CONGRATULATIONS

on your purchase of the Radial ProAV2. Radial products are easy to use and
this short manual contains all the information you need to start using your
ProAV2 right away. For more information on the ProAV2, and other Radial

OVERVIEW

The Radial ProAV2 is a two channel passive direct box. This innovative DI
features a 'Swiss army knife' of input options making it the perfect DI for
professional AV integrators and rental companies that regularly deal with a
variety of system interface problems.
The Radial ProAV2 is equipped with standard ¼" instrument inputs for each
channel making it easy to connect stereo instruments or two mono ones.
Stereo RCA and 3.5mm jacks allow for easy connections from consumer
-10dB audio devices, like MP3 and CD players, to microphone snakes.
At the heart of the ProAV2 are two custom Radial transformers that convert
the high impedance inputs to a balanced low impedance signal while isolating
noise caused by ground loops. Constructed with a two piece 14 gauge steel
enclosure the ProAV2 is well suited for years of touring and rental use. Enjoy!

CONNECTING THE ProAV2

Before connecting the ProAV2 make sure the sound system is turned off and
all levels are set to zero. This will avoid any pops in the sound system that
could damage loudspeakers. Also confi rm that the GROUND, PAD and LIFT
buttons are in their "out" positions. The ProAV2 is passive and does not require
any power whatsoever to work. Phantom power will not damage the ProAV2
if applied.

ProAV2 BLOCK DIAGRAM

Follow the block diagram from the inputs on the left to the outputs on the right. A
really cool feature with the ProAV2 is all the input jacks are paralleled together
in stereo. This makes any hi-Z jack a handy patch point. For example, a CD
player may be connected to the RCA jacks and the signal sent to a computer
sound card via the 3.5mm jack in addition to the balanced XLR outputs.
