Radial JDI vs J48
Recieved my J48 yesterday and I have to say – nothing against the JDI – but the J48 is massively dynamic with far more clarity to my ears than the latter. A much stronger and clearer signal to feed the DAW with this unit for sure. Granted it’s no U5 or anything, but for a DI “box” this is impressively close.
Very impressive…

Radial Engineering
When comparing passive DI boxes, begin by considering the instrument or audio source, the number of channels required for a particular setup and the feature set. You will find that most passive DIs share features such as an input pad and a ground lift. All Radial DIs have built-in filters to reduce parasitic noise caused by magnetic fields and radio frequency waves.
The primary difference between the various models is the type of transformer that is employed. We spend hours listening to various transformers to find the best one for a given application and price point. For instance, the industry-standard Radial JDI employs a USA-made nickel core transformer with dual Faraday shields and a MuMETAL® external can. MuMETAL® provides upwards to 10,000 times greater shielding than aluminum. This combined with the steel outer shell protects the sensitive high impedance signal from outside magnetic fields from power transformers that can pollute the signal.
The JDI, JDI Stereo, JD6 and Duplex have exceptionally linear frequency response from 10Hz to 40kHz.
The ProDI employs a custom-made Eclipse transformer manufactured to our specifications for a more economical option to the Jensen and is also equipped with a MuMETAL ® shield.
shield. The ProDI, ProD2 and ProD8 share the same Eclipse transformer which is linear from 20Hz to 18.5kHz and works extremely well for live touring.
The Stage-Bug SB-2 employs a copper shielded Eclipse transformer which delivers great performance from 40Hz to 18kHz; the Stage-Bug DI’s compact size makes it ideal for weekend club dates and jamming with friends.
While the industry standard Radial JDI and JDI Stereo are primarily intended for use with instruments such as bass, acoustic guitar and keyboards, the two-channel Radial Duplex adds greater connectivity for AV applications where you may need to connect to CD players, video machines, or any device with consumer-type output connections. The same follows with respect when looking at the Radial Pro series. If you are using the DI in a live situation and the PA system is band-limited up to 18kHz, you may find that the ProDI will work perfectly well. If on the other hand, you are recording in the studio you may want to capture the very highest harmonics, the JDI would be a better choice. The Radial JDI is used by Tony Levin, and The Who while the Pro series DIs like the ProD8 are used by U2, Rush, and the Rolling Stones.

Radial JDI and J48 DI boxes challenges and problems
Hi there,
I usually use the DI boxes in both live and studio for re-amping and later sound design and used Radial units for ages. However, recently I was testing the units in some unconventional ways to just get ideas. The rule of thumb is to use Active DIs for passive instruments (e.g. J48) and Passive DIs for active instruments (e.g. JDI). However recently I discovered two problems and decided to send the Radial technical support an email so they could shed some lights on the matter. Here I copy the email I send:
Hi there,
Thanks for such great sounding and durable products, I’m a big fan.
I’v been using Radial J48, JDI, X-AMP and others for years now. However, recently I was using both J48 and JDI on passive electric guitars just for testing and I realized two things.
1- I realized that does not matter which device I use (JDI or J48), when I use the THRU jack on either of those devices my passive guitars slightly become dull sounding and a little bit darker. I think it can be expected from the JDI as it is a passive DI which I assume by splitting the signal, it somehow affects the sound (same old passive units problem, e.g. passive Ernie Ball Volume Pedals). But how about the active J48? I have 2xJ48 units and both behave the same as the JDI, that if I insert a cable into the THRU jack, I can audibly hear the difference in the sound becomes muddier, darker with less definition. As I said I somehow expect this to happen for JDI as a passive unit against passive guitars/instruments, but J48 makes me wonder. I would appreciate if you can shed some lights on this issue.
I usually use my J48 for recording unaltered-raw guitar signal for re-amping, but now that I realized the THRU jack somehow affects the signal in a way that is not ideal to my ears I’m wondering what are my options? Currently I’m using JDI (with a trick even for passive instruments) as I explained below since I found this issue with the J48.
2- After finding about the issue with the THRU jacks on both JDI and J48, I thought, well maybe it would be a better idea to just use the JDI (because I always preferred its smooth, warm yet clear sound of the Jensen Transformer in the JDI anyway) even for passive instruments (magnetic electric guitars) and instead use a high quality buffer between my guitar and the JDI? I did that and it was great! I used a high end Cornish/Empress dedicated buffer (I assume even a good Boss pedal would work here) right before the JDI, then through JDI to my Focusrite audio interface. This way my pickups see the active buffer, and then buffer gets smooth out by the JDI transformer before going into my interface. I honestly like this sound much better this way than the J48 which I used for years.
Now the second question is, is there any downside to use the JDI for passive pickups and compensate the needed gain via the preamp on the interface? Theoretically speaking, does it affect my passive instrument’s sound and cut some harmonic contents and crucial frequencies this way? Is my solution for putting a buffer before the JDI a viable solution if I like and prefer the smooth sound of the JDI over the J48?
And the last question is that I read on the manual of both units that the input impedance for both units are way less than 1MO (which is usual for amps, pedals, etc…) does their low impedance somehow makes both units not-ideal for guitars in general? (for mostly magnetic passive guitars).
As I said, I’m often recording guitar/bass amps in both live and studio (often dry/wet for guitars) and usually use Radial units for mostly re-amping purposes and sound design.
Best Regards,
———-
Can anyone confirm or try their THRU jack and let me know? I have tried 3 units so far and all behaved the same. You have to listen with a good pair of speakers in a acoustically treated environment, or even better with a good set of headphones. By just plugging in any jack into the THRU the sounds audibly changes, when using passive instruments (again surprisingly for both JDI and J48).
Also, do you guys think my solution of using a buffer before the JDI is a good solution if I prefer the sound of the JDI transformer sound? Is there any downside to this?
Cheers,
Radial JDI Passive DI and J48 DI Package
Your Complete DI Kit!
Sweetwater put together the Radial JDI Passive DI and J48 DI Package to cover just about any recording or live gig scenario. In addition to the active and passive DIs, the bundle also includes an array of essential cabling and a padded gig bag to hold everything.
Radial JDI
Radial J48
The Radial JDI passive direct box is the kind of premium-quality direct tool you need for great sound and rock-solid reliability on stages and studios anywhere. The Radial JDI features a Jensen isolation transformer to give you the best performance possible at all frequencies. This box can handle very high signal levels without distorting, and its passive design helps to eliminate 60-cycle ground loops. It’s great for everything from passive and active guitars and basses to analog and digital keyboards. Take it from Sweetwater: the Radial JDI is a dependable, quality performer!
The Radial J48 is an active direct box that has been specifically designed to work around the limited current that is available with 48-volt phantom power and do so while delivering the pure and natural sound of the instrument. A unique switch-mode supply steps up the internal rails to allow an input signal of up to 10 volts without any noticeable distortion. The single most important development goal of the Radial J48 was increasing the headroom without compromising sound quality. To this end, every possible effort was made to deploy the limited energy resources of phantom power to the audio signal path. To begin, phantom power is converted using a super-efficient digital switch-mode power supply that steps up the internal rail voltage to an impressive 10 volts. This allows you to hit the J48 with as much as 9 volts without choking! To further increase available horsepower, all non-essential devices such as power-hungry LEDs are turned off when the J48 is in use. A typical LED requires almost as much current as does the complete audio circuit!
This bundle includes: 1 Radial JDI transformer-equipped passive DI 1 Radial J48 active 48-volt phantom-powered direct box 2 Pro Co EXM-20 20′ Excellines microphone cables, XLR male to XLR female 2 Pro Co EG-20 20′ Excellines instrument cables, 1/4″ TS male to 1/4″ TS male 1 Gator G-Mixer 1212 padded carry bag

Longform candid interviews with music producers and audio engineers covering mixing, mastering, recording and music production.
I’m a big fan of Radial Engineering’s products, and Tape Op has published reviews of a number of Radial’s products: JDV Mk3 Class-A DI in Tape Op #36; JD7 Injector multi-output guitar re-amping and distribution system in #38; X-Amp active re-amping device in #45; and JPC stereo PC/AV DI also in #45. A few months ago, I purchased a bunch more gear from Radial, including the JDI passive direct box and Reamping Pack that I’m reviewing here, because I’m finding myself recording more instruments direct and re-amping them later. And just about every recording session has involved some use of my growing collection of Radial products-whether it’s something standard like recording bass through a DI or something less ordinary like taking a vocal track and creating a submix of re-amped vocals through multiple guitar amps to add healthy amounts of sugary grit to the vocal performance. Radial Engineering’s Reamping Pack is a great way to kickstart your addiction to re-amping. It’s a kit that includes a J48 Mk2 phantom-powered direct box and an X-Amp re-amper in a foam-lined, plastic case that holds both boxes along with the 15 Volt wall-wart for the X-Amp. Because the X-Amp was already reviewed, I’ll focus on the J48 here.
First of all, it’s worth mentioning that inside the J48 is a digital power supply that converts standard, low-current 48 V phantom power into 10 V rail-voltage for the internal amplification circuitry and oversized capacitors that store energy to allow for high-current transients. Thus, the J48 has much higher headroom and far less distortion than typical phantom-powered devices, while still consuming very little power. Other innovative features include a resistive mixer circuit that you can switch in to sum two sources (useful for connecting a stereo device to a mono input); an 80 Hz low-cut filter that will give you more headroom if your instrument has unneeded low end (like an acoustic guitar might); and a phantom power LED that you can light up momentarily (but will go out automatically so you don’t waste any precious power). There are also switches for 15 dB pad, ground lift, and polarity reverse.
The JDI is the passive sibling to the J48. Inside the JDI is a Jensen JT-DBE transformer that exhibits extremely-low phase distortion (4 deg at 20 Hz) and flat frequency response (within 0.1 dB from 20 Hz to 20 kHz). Like the J48, it has switches for 15 dB pad, ground lift, polarity reverse, and resistive mixing. It also has a speaker setting that engages a 30 dB pad and a low-pass filter to mimic the sound of a mic’ed 12” speaker. With this setting enabled, the JDI can be connected to the outputs of an instrument amp, in parallel with a speaker load, so that you can record the sound of the amp’s electronics direct.
Both DI’s, like all of Radial’s boxes, are built tougher than any other audio products I’ve seen. Switches and connectors are recessed behind the “book ends” of the heavy-gauge steel box to prevent accidents (switching or breaking), the bottom is completely covered with a single piece of high-quality rubber, and aircraft-rated bolts tie together removable components. Also, each box is so well- labeled that you may never need to read its manual… but you should, because Radial’s manuals are extremely comprehensive and informative. For example, if you do read the JDI manual, you’ll learn that you can use the JDI “backwards” (with an XLR-F gender-changer) as a passive re-amping box!
My first test of the two DI’s was on a Fender P-Bass track. In the past, I’d been using a low-cost Whirlwind IMP 2 to take a direct feed from the bass in parallel with a mic’ed track. I’d always convinced myself that this setup sounded “good enough,” because I wanted to reserve my more expensive DI-equipped preamps for other instruments, and I usually ended up using more mic’ed sound than direct. Well, trying the J48 and JDI on bass was an ear-opener. The jump in sound quality was immediately noticeable on the first note. Both Radial DI’s sounded great, but in the end, I preferred the transformer-based JDI over the active J48. The JDI really brought out a beautiful, full tone, especially evident on the E string. This first test encouraged me to try other DI’s on the bass. And nowadays, I go back and forth between the JDI and an Avedis 1122-equipped BAE 312A preamp channel (reviewed in Tape Op #45) that I purchased recently to supplement the eight API 312’s and two BAE 312A’s that I use for recording drums. I choose the BAE 312A when I need a more aggressive bass sound, while the JDI is my go-to DI when I want a fuller sound that adds cohesiveness to the bottom end of the mix. The JDI does load the pickup some, so with some instrument/amp combinations, you can hear an unwanted effect. Because of this loading, I almost always prefer the J48 over the JDI on electric guitar. The J48 seems to bring the guitar more “forward” in sound with its higher input impedance than the JDI. And especially with single-coil pickups, the high end softens noticeably with the lower-impedance JDI. On the other hand, this trait can be an advantage. For example, I’ve found that the JDI works wonders for taking the icy bite out of a Strat’s bridge pickup when recording to digital. (Note that the higher-priced JDV and JD7 have a “drag” control to vary input impedance and therefore pickup load.) On active instruments, it’s a much tougher call. Both DI’s sound great, but certain sounds feel stronger out of one DI than the other. In general, it’s usually a choice of smoother lows from the JDI or stronger highs from the J48. For example, some harmonically-rich patches on my Moog Voyager benefit from the J48’s more forward high end, while sounds with simpler timbres are warmer through the JDI. Choosing which DI to use is akin to choosing which mic preamp to use, so it’s great to have a choice!
If you’ve never tried re-amping, I urge you to give it a try. You’ll be amazed at how much fun you’ll have (and how much control you’ll gain) by recording your instruments direct and re-amping them (especially after you’ve edited them) through different effects and amps. Radial Engineering’s Reamping Pack is really a great way to start as it includes the two devices you’ll need, and its street price of $300 is less than the combined street prices of the J48 and X-Amp ($180 each). Plus, it comes with a carrying case. The J48 Mk2 is an outstanding active DI box, and it complements the Class-A X-Amp re-amping device well. Also, the JDI by itself is a fantastic passive DI, and as I mentioned above, if you “turn it around,” you can use it as a passive re-amping box. (Reamping Pack $450 MSRP, J48 and X-Amp separately $200 each, JDI $200; www.radialeng.com)
Bộ lọc nhiễu đàn guitar Radial J48
Tại sao chúng ta nên dùng DI Box?
– Guitar điện, guitar bass và guitar acoustic có pickup là loại nhạc cụ phát ra mức tín hiệu rất yếu và trở kháng rất cao (thường là khoảng 10.000 ohms), ngõ ra chuẩn 6.3mm unbalance (TS)
– Trong khi các loại amp cho guitar và guitar bass có thể tiếp nhận và hoạt động tốt đối với loại tín hiệu trở kháng cao này (do mục đích thiết kế) thì các loại bàn trộn âm (mixer) và các loại thiết bị ghi âm trong cả studio và sân khấu thì thường chỉ đáp ứng tốt với nguồn tín hiệu có trở kháng thấp (từ vài trăm đến vài nghìn ohms), chuẩn kết nối balance (XLR cho micro hoặc TRS cho line)
– Do vậy, khi cắm guitar vào bàn trộn âm hay các thiết bị ghi âm thông thường sẽ có hiện tượng rú rít, tạp âm (noise). Đây là nguyên nhân kỹ thuật vì sự không tương thích về mặt trở kháng gây ra. Ngoài ra, còn có yếu tố rủi ro như chất lượng đàn, chất lượng dây giắc, tạp âm do môi trường (sân khấu) và sóng radio gây ra các loại nhiễu nói trên
– Đấy là lý do mà DI Box ra đời (DI = Direct Injection), nó đồng bộ trở kháng từ trở kháng cao sang trở kháng thấp (Unbalance TS to Balance XLR) đồng thời nó được tích hợp chức năng lọc nhiễu radio, nhiễu do các vòng lặp gây ra do không nối đất (hay còn gọi là thiếu mát)
– Ngày nay có nhiều hãng sản xuất fuzz guitar có tích hợp chức năng DI, cạc âm thanh có chức năng DI. Tuy nhiên tất cả những thiết bị trên chỉ tích hợp mạch DI đơn giản, không thể có chất lượng tốt như một DI Box chuyên biệt
– Vì vậy, dù là chơi trên sân khấu hay ghi âm tại studio, các guitarist nên trang bị thêm 1 chiếc DI Box chất lượng tốt, phù hợp với chiếc guitar của mình để không chỉ đảm bảo tiếng đàn sạch sẽ không bị nhiễu, mà còn có âm thanh chất lượng tốt cho track của mình.

Which DI Box Do I Need? | 7 Essential DI Boxes You Need
You’ve probably already heard of the many benefits of using direct boxes (DI boxes), so I’m sparing you the details in this article. The question we’ll be answering is “which DI box do I need” because there are many different types of DI boxes out there. After reading, you’ll know exactly which product you’ll need depending on the instrument(s) you’re using and the application!
Choosing the right DI box; it’s like choosing the right tool for the job. The first thing we’ll need to consider is the output-impedance of the instrument/device you’ll be using. Instruments like guitar/bass require DI boxes which can handle higher voltages. It’s even more important to consider if they’re using active/passive pickups. Similarly, there are also both active/passive DI boxes and there’s even another “special” category that includes DI boxes with specific functions. If it sounds overwhelming, you’ll be surprised how knowledgeable you’ll become after taking the time to study this guide. The last thing I want to mention is that we’ll be looking exclusively at DI boxes by Radial Engineering since they’re basically the industry-standard. Let’s get started!
ACTIVE DI BOX
PASSIVE DI BOX
SPECIAL DI BOX
CONCLUSION
ACTIVE DI BOX
You need the Radial Pro48 Active DI Box if you’re using both active/passive instruments
So, which DI box do I need if I’m looking for an all-in-one solution? I asked myself the same question before purchasing my first DI box and the Radial Pro48 seemed to be the most affordable, yet most versatile product.
It’s powered by your audio interface’s +48V Phantom Power and has been designed to work with both active/passive instruments.
Frequency Response 20 – 20,000 Hz Dynamic Range 99 dB Input Impedance 220 kOhm Output Impedance 600 Ohm Noise -82 dB Maximum Input +9 dBU Features Attenuation, Ground Lift
I’ve personally used the Pro48 with active/passive guitars and active/passive bass guitars. However, you can also use it with electro-acoustic guitars equipped with pickups. Since its internal rail voltage sits at 9-Volts, you’ll be fine with most active instruments (they usually don’t exceed 7-Volts).
Considering the fact that the Radial Pro48 doesn’t include more than one input, you won’t be capable of using it in stereo with keyboards, mixers, etc…
One of the advantages of using active DI boxes like the Pro48 is the “transparency”. In other words, they won’t colour your sound like passive DI boxes would. It’s really a matter of personal preference, but your instruments will sound exactly as they are.
The additional throughput is also excellent for duplicating your original signal to feed into your amplifier simultaneously.
For example, you may want to record your DI signal and use microphones to record your amplifier at the same time to have options. It’s mostly used in live situations, but I use this technique in the studio all the time!
Lastly, the -15 dB attenuation is really important for active instruments. Even if the Pro48 has been designed to handle the voltage, my active guitars/basses are usually WAY too loud. I don’t usually need to use it with passive instruments though.
So, the Radial Pro48 is perfect for active/passive guitars/basses and electro-acoustic guitars.
You need the Radial J48 Active DI Box if you’re looking for maximum headroom and minimum noise
If you’re willing to spend more, I strongly recommend splurging on the Radial J48. It’s pretty much the same product as the Radial Pro48, but one of things it does better involves its dynamic range (+10 dB to be precise).
The J48 is basically the “premium” version of the Pro48 and also produces less noise.
Frequency Response 20 – 20,000 Hz Dynamic Range 109 dB Input Impedance 220 kOhm Output Impedance 200 Ohm Noise -99 dB Maximum Input +10 dBU Features Attenuation, Ground Lift, Merge, Polarity, HPF
The fact that it’s been designed to handle louder transients also makes it more suitable for drum modules/drum machines. In these cases, the optimized signal-to-noise ratio can also make this unit more beneficial. The J48 produces -16 dBU of input noise and -17 dB of internal noise less than the Pro48.
However, my favourite feature is the ability to transform the J48 into a passive summing mixer.
Basically, the J48 includes a “merge” function that can convert its input/throughput into two passive stereo inputs. The resulting output will contain both signals mixed down into MONO. It’s great if you wanted to sum the left/right channels of your keyboard instead of having the stereo image.
If you wanted stereo though, you could also consider the J48 Stereo instead!
Other than that, the J48 also includes the same features as the Pro48 with the additional HP Filter (80 Hz) and polarity reverse (useful if your audio interface doesn’t include this feature). In my opinion though, these features are more useful in live situations.
That being said, I think the Radial J48 would be the better option for stage-use. However, it’s just as good for studio sessions and I especially recommend it if you’re playing an electronic drum kit (use the J48 Stereo though).
The Radial J48 does everything the Pro48 can do and more! If you’re working in stereo you’ll need the J48 Stereo.
PASSIVE DI BOX
You need the Radial ProDI Passive DI Box if you’re using high-output instruments
So, which DI box do I need if I’m using high-output instruments? In other words, we’re looking for the DI box most suited for high-impedance instruments and we’re starting with the Radial ProDI.
Active DI boxes can work with both high/low impedance sound sources, but Passive DI boxes WON’T work with low-impedance signals.
Frequency Response 20 – 18,500 Hz Dynamic Range 128 dB Input Impedance 140 kOhm Output Impedance 150 Ohm Maximum Input +18 dB Features Attenuation, Ground Lift
That being said, most guitars/basses and other instruments like keyboards still fall into the category of high-impedance instruments. The only exception would be guitar/bass pickups that have relatively low output-gain. 99% of the time though, the Radial ProDI will get the job done!
If versatility wasn’t an issue, I’d seriously recommend going passive.
Passive DI boxes like the Radial ProDI will react much better to these higher-output instruments since their dynamic range/maximum input is far greater. For example, the ProDI’s dynamic range exceeds the J48’s by +19 dB and input-gain by 8 dBU.
The only thing you’ll be sacrificing is frequency-response (the highs are rolled-off).
However, the Radial ProDI actually has more of that analog/vintage sound. Passive DI boxes use transformers and can either pleasantly colour your tone or it can be rather unpleasant…
Rest assured that Radial DI boxes sound excellent and use some of the highest-quality transformers. The ProDI uses an Eclipse ET-DB2 transformer.
Other than that, the Radial ProDI is basically the passive version of the Pro48 and also offers an equivalent stereo model (for keyboards, drum modules, etc…).
You need the Radial JDI Passive DI Box if you’re using high-output instruments, but want more quality
Once again, if you’re willing to spend a little more, the Radial JDI provides noticeable improvements compared to the ProDI. Similar to the difference between the Pro48/J48, the JDI provides more headroom and improved frequency-response (in this case).
Another advantage with the Radial JDI is the use of Jensen transformers (JT-DB-EPC).
Frequency Response 20 – 20,000 Hz Dynamic Range 135 dB Input Impedance 140 kOhm Output Impedance 150 Ohm Maximum Input +21 dB Features Attenuation, Ground Lift, Merge, Polarity, HPF
These transformers are sought after because of their frequency-response, low distortion, low phase-deviation, noise-rejection and ability to handle high-output signals. The main reason the Radial JDI is more expensive is because of this one component and I think it’s worth it.
It also includes the same features (like “merge”) as the Radial J48.
Compared to the ProDI though, the JDI can offer +7 dB of dynamic range and +3 dB of maximum input. It also covers the full frequency-spectrum (20 Hz – 20,000 Hz) and is one of the least noisy passive DI boxes.
Usually, the disadvantage with passive DI boxes is their noisiness and reduced frequency-range.
That being said, the Radial JDI is one of the DI boxes with the most headroom on the market without sacrifice. I personally believe you’d be much better off with this unit, especially if you had no low-output instruments to worry about.
Although active DI boxes may be more versatile, passive DI boxes like the JDI perform much better with high-output instruments. If you’re using drum modules/drum machines almost exclusively, you cannot live without this guy!
Because of the Jensen transformer, the Radial JDI will actually improve your signal and it’s also available in stereo.
SPECIAL DI BOX
You need the Radial JDX 48 Amp DI Box if you want to record using your amplifier’s speaker output
So, which DI box do I need if I intend to record my amplifier using its speaker output? I was personally shocked to find out that this was possible thanks to the Radial JDX 48.
Prior to finding out about this invention, I had attempted to record my amplifier using the headphones output (not the best results, but it worked).
Dynamic Range 114 dB Input Impedance 15 kOhm Output Impedance 2 kOhm Noise -100 dBU Maximum Input 120 Watts Features Polarity, Ground Lift
However, the Radial JDX 48 provides the best results without needing to use microphones. You can record the sound of your amplifier directly without any deviation from the original tone. Most amplifiers include the standard 4-Ohm/8-Ohm outputs for cabinets.
You’d simply use one of them (4 Ohm is better) and connect it to your JDX 48 as if it were the speaker.
This DI box also includes a throughput which can also allow you to connect your signal to your cabinet during live performances. You can also use it in the studio if you want to record both the sound of your amp “dry” and with microphones.
The Radial JDX can handle up to 120 Watts at 8 Ohms, so most amplifier heads will work!
In my opinion, this active direct box would be an excellent alternative for guitarists/bassists. It can be used to run these instruments as well, so it’d be better than the Radial Pro48 if you were running a guitar/bass studio.
You’d essentially be maximizing the amount of possibilities you could use to record your instruments. You could record with an amp, without an amp, with cabinets, without cabinets and/or any combination of the above!
The other DI boxes we talked about wouldn’t be capable of handling the signal from your amplifier, so the Radial JDX 48 is an excellent alternative (no stereo version though).
You need the Radial PZ-DI Piezo DI Box if you’re using instruments that use Piezo pickups
So, which DI box do I need if I need to record instruments using Piezo pickups? You’ll most likely need the Radial PZ-DI if you want to get the most out of your instruments since Piezo pickups work differently.
Piezo pickups can deliver loads of up to 10 mOhms which is higher than most pickups!
Frequency Response 20 – 20,000 Hz Dynamic Range 105 dB Input Impedance 220 kOhm/1 mOhm/10 mOhm Output Impedance 200 Ohm Features Attenuation, LPF, HPF
What I really like about the Radial PZ-DI though is its ability to switch between different impedances (220 kOhms, 1 mOhm and 10 mOhms). Basically, you can actually use this DI box to connect many different instruments including standard guitars/basses.
I think it’s more valuable simply for the fact that you can alternate between different input impedances!
The Radial PZ-DI also falls into the active DI box category, so it delivers “transparent” frequency response. It also includes both a LP filter and a HP filter knob that can be adjusted. Basically, this will really come in handy if in live situations more than in the studio, but you’ll still need it in the studio to record Piezo pickups.
The throughput is also beneficial for duplicating your original signal to send it to an amplifier.
However, if you’re not planning on working with Piezo pickups, the Radial PZ-DI wouldn’t be that useful to you. Most instrument pickups will never exceed the 1 mOhm impedance range, so the toggle switch would mostly remain at 220 kOhms.
For example, most guitars usually produce anywhere from 10-50 kOhms. That’s much lower than what Piezo pickups are capable of!
If you’ll be working with Piezo pickups though you absolutely need the Radial PZ-DI.
CONCLUSION
Which DI box do I use (and why)?
I could’ve gone over even more DI boxes (I may add some to the list), but I simply wanted to simplify things for you. I pretty much studied Radial Engineering’s entire catalogue and distilled it down to 7 essential DI boxes you need to own.
Although, you most certainly won’t be needing all of them unless you’re working for others.
To be completely honest, the need for DI boxes is slowly dissipating because of the HI-Z-enabled preamps on most audio interfaces. They’re designed to handle the higher-impedance signals from guitars/basses, so you really don’t need a DI box anymore.
So, why do I still use one? And which one DO I use?
I incorporated my Radial Pro48 into my recording system because I use it to duplicate my signal using the throughput. It doesn’t go into an actual amplifier, instead I route it to my Universal Audio Arrow which I use as my amplifier (usually the Friedman BE100 plugin).
The balanced XLR output is simply used to preserve my DI performance “clean” so that I can potentially use it in the post-production stage for layering and/or replacing.
I talk more about my process in my guide on the “best way to record bass guitar at home”. I also mention it in my guide entitled the “best way to record electric guitar at home”.
The reason I use the Pro48 is simple… I was looking for an affordable DI box that provided maximum versatility. However, I would’ve probably chosen the Radial JDI if I could go back in time…
The truth is, unless you’re using some old-vintage analog equipment, you won’t really need an active DI box. Most modern instruments are high-impedance so you’ll get even better results with passive DI boxes (make sure it’s good though, transformers can make/break your signal).
If anything, I hope my article was able to help you sort the overwhelming amount of different DI boxes. There are basically three categories and most of us only really need one or two of these devices. I chose Radial Engineering as my case study because they’re actually the industry standard. Go to any venue/studio and guess what they’re using… Radial! If you enjoyed learning about DI boxes with me, consider subscribing to my weekly newsletter for more helpful guides just like this one.
