User Guide

CONGRATULATIONS on your purchase of the Radial Pro48 active direct

box. As with all Radial products the Pro48 is easy to use. This short manual

contains all the information you need to start using the Pro48 right away. For

OVERVIEW

The Pro48 is a great sounding active direct box. It has been optimized to

produce maximum headroom and dynamics while working within the limited

current available from 48V phantom power.

The Pro48 employs a unique switching power supply that steps up the current

from phantom power to produce higher internal rail voltage than typical

active DI’s. This makes the Pro48 capable of peak input transients to 9 volts

without any noticeable distortion, making it perfect for both active and passive

instruments. The Pro48 is equipped with an input PAD to help prevent overload

from hot signals and a ground lift to reduce noise caused by ground loops. The

balanced XLR output can drive very long cables without appreciable signal

loss. The Pro48 is constructed for heavy use in the studio and on stage.

Pro48 BLOCK DIAGRAM

To fully understand the Pro48 follow the block diagram from the inputs on the

left to the outputs on the right.

Pro48™ User GuideRadial Engineering Ltd.

After the paralleled input and thru jacks the signal passes through a switchable

15dB PAD which allows the Pro48 to handle virtually any audio device from

passive pickups to high output instruments without overloading.

Next comes the active drive circuit that converts the signal to balanced low

impedance mic-level for transmission over long cables without noise or signal

loss. The switching PSU steps up the current from phantom power and the

drive circuit uses the higher rail voltage to increase headroom and dynamic

range.

The switching PSU uses a transformer in the DC path to block noise caused

by ground loops. The ground LIFT switch interrupts the ground path around the

transformer to help suppress noise from bleeding through into the audio path.
