Radial Engineering Pro 48 Active DI Box

Description

Active DI Box

Jack in/thru
XLR out
– 15 dB pad
Ground/lift
Operates with 48V phantom power

Exceptional sonic performance

The Pro48’s innovative internal switching power supply significantly increases headroom producing less distortion while yielding a smooth, linear response that extends from 20Hz to well above 40kHz. This results in natural, uncolored signal that is as good or better than DI boxes costing several times more. The superior performance makes the Pro48 an ideal candidate for use with battery powered active basses and acoustic guitars that tend to overload other direct boxes.
