Product Description

The Radial Pro48 direct box, an active direct box with nine times more headroom than the competition, less distortion and a great price.

Following the trail blazed by the immensely popular Radial J48, the Pro48 is a scaled back version that incorporates the same digitally controlled switching power supply that steps up the rail voltage from the typical 1 volt to an astounding 9 volts!

Today, most instruments such as acoustic guitars and basses are equipped with internal preamps called buffers. These can develop anywhere from 3 volts to 6 volts when turned up and played hard. This excessive output level overloads typical direct boxes as they are unable to handle the signal due to the limitations of phantom powering. Radial developed a work-around in the J48 by using the same trick that power amplifier companies now use to increase the efficiency of their amps. It is called digital switching. Essentially, Radial takes phantom power and converts the high voltage and low current from DC into AC using a special transformer and digital timing chip. They then filter the power and reconvert it to DC to get their 9 volt rails. High rail voltage means more signal handling and less distortion. With demanding customers like Bruce Springsteen and Jerry Douglas using the Radial J48 on their guitars, you can be sure the sound is right.

The Radial Pro48 features a compact yet ultra-solid 14 gauge steel enclosure with a book-end protective sleeve. It is equipped with 1/4 in. input and thru, -15dB pad, ground lift and 48V phantom power indicator LED. zZounds is an authorized dealer of Radial products.

Customer Reviews
4 out of 5 (1 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Good find, it sounds big and detailed on acoustic guitar."
Sound: I bought both a Radial passive DI and an active DI at the same time. The passive one has a Jensen transformer, model JDI; and the active model was the Pro48. At home, the active one sound more transparent in the mids than the passive one with the Jensen transformer. On the stage on my first use, the active one Pro48 was to me obviously clearer and pretty much a revelation. Like wow, what do we have here. On the other hand, the passive model (which cost about $200 versus about $140 for the active one) was good but not "special". I think I'll use the passive one if I get an input thats too hot. And, in the future, I'm going to only buy the Pro48 or maybe the more expensive active model, the J48, that is supposed to have more features but the same sound. My first use of the Pro48 was on an acoustic guitar. The Pro48 sounded better than the guitarists preamp rig (a higher priced floor preamp specifically for acoustic guitars). The guitarist's rig sucked life from the sound when compared to plugging straight into the Pro48. So he plugged straight in and sounded big and full and detailed. Really a nice sound considering its from a DI on a stage. So for sound, I'm giving it a 10 but maybe there is something out there that is better but I haven't heard it. of course, I haven't heard the really pricey DI's. On the other hand, I own a couple of focusrite ISA428's that have guitar inputs with Lundhal transformers (that I've used in a studio) but again to me, the ISA428's DI sound good but not "special" in terms of transparency and detail. I would definitely use the Pro48 and would not even consider the ISA428 on acoustic steel string guitar; even in a studio. Feature: Has pad and ground lift but no high pass filter. Pretty basic. Ease of Use: Just have to be careful plugging in and out cause there is a loud pop. No loud pop on the passive one. Quality: Heavy steel. Road worthy. Manufacturer Support: Haven't use it. Good videos on Youtube help me select this product. Overall: I give it a 9 because who knows, there might be something else out there that is better that I haven't tried. I expect this product to last a very, very long time. I'll buy more of this or maybe the more expensive model, the J48, In fact, unless something changes, I might only buy this DI from now on.
