The Radial 48 is a day active DI box analog that is used exclusively with phantom power via the mixer (48v).
1 input jack, 1 thru jack and XLR male output.
On the side push switch input 2: - 15 db and 1 merge.
On the side push switch output 3: Ground, Low cut and Polarity
1 LED to verify power 48v is sent. It is a pressure on the low cut switch that allows this check. LED can shine that at this time. I see it as a fault, but not wanting to lose Radial says no millivolt, all for her.
(Must see!)


The J48 is for confident musicians sound their instruments and eager to find this in a grain mix it in the studio or on stage.
Function merge to me personally is of no use, it is an adder for two input sources to a single output.
The low cut proves very effective on a rumble from below the stage to an electro-acoustic.
The ground lift and polarity inverter can adapt to all situations and configurations.


This is why this DI. The sound of the instrument is perfectly reproduced. The tone knob on my Fender Precision becoming effective as ever. The wear of the ropes, then attack all these parameters are shelled over time find yourself their superb.


I personally discovered for two weeks. But as a professional stage it's been a long time that I see the gradual replacement of Ar 133 other brands including Radial. Musicians always pinailleront too.
Radial seems to be a mark in line with the world of music together technicians and musicians with a common language. The radial J48 is acclaimed by both sides which to me means everything.

DI analog
running 48V power supply
1 input jack (guitar)
1 output jack (to amp)
1 XLR output (to sound card)

ground lift
low cut
-15 Db
phase inversion


easy to use


very good DI allows me to record the guitar signal directly while playing on my amp (by me)!
with the X-amp I pass the signal REAMP in my head and the result is identical to the original.
very good return signal so


I use it for 3 years for shooting guitars live (for the réamping) with the X-amp from the same manufacturer!


we forget ... so it is good!

Pure ANA.
Connectors classic XLR out, Jack (x2: input + "through") as input.

No battery: 48V Phantom power only through.

Not small, not tiny but not too-big-inspires confidence.
Not "cheap" anyway. A


DI, whatever. Simpler than that you die ...

Oh yes, there's the button "merge" that can "summon" the 2 input Jack (input and "through").

Otherwise, ground lift,-15dB, low cut (high pass filter-6dB at 80Hz), phase inversion and an LED to indicate that there is 48V but only lights qd we push the button "Low cut" to keep all the juice to avoid saturating the DI-peaks

It is also equipped with a foam non-slip on to do less. Practice to prevent slipping the ID if installed on an amp.



Seriously, this is the best DI I heard.
On a good low (5 or 4 strings), it's just excellent.

The bass is clear, right, attack transients and excellent string, not a breath ... Everything is there. And to make it saturate, it must go!
(According to the specs, +12 dBu nominal, +21 dBu peak!)


Before, I tried Berhingtruc-it works. If so, a 133-BSS-classical, a Palmer-remember reference-or DI output of the amp Kustom bass player ...

The DI-is still 2 classes above, in my opinion. A DI

Beware if looking for transparency is your quest, this product is to discover, for if one seeks against staining, go your way ... this is not for you ...

I discovered this by accident. My boss had made a comparison between a DI Radial and Avalon, a Lower, who then came home on a Studer console ...
I am blind and I found cost gniale the difference between the two sources, I immediately recognized the Avalon ...
Avalon color (too much or not enough for my taste, but only my opinion) with Radial sound is transparant ... transients are well respected, there is no boost particulire. .. It breathes ... There is no crushing of the signal ...

40Khz bandwidth should be enough to keep toadflax 20 20k, right?

On the website, the dtailles characteristics of the product speaks for even ...
The client list is a proof of quality supplmentaire there are a lot of men ... Jazz

I love its transparency ... and more design exudes quality has beefy air ... We hear about it in 10 years ...
I tried diffrente DI front, Country Man, BSS, Berhinger, but still not as big DI Manley and Chandler ... I'm not color the sound partisant taking with DI, but rather to pramplis or mix with well doss effects. I was looking for 2 DI for keyboards or for acoustic instruments, I utlis at work, I found concrete, and when I went to the site, I saw all the characters tics, and I realized what I had heard ... It's srieux ...

As for qualitprix report, it is excellent ... I have found 2 on Ebay USA for $ 400 (shipping included). 185 our friend across the Rhine, Toto ...

If I just bought 2 for me, it is not by chance that I made this choice ... Go !!! Yet something more to the tools, bringing everywhere !!!
