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 products, visit our web-

site, www.radialeng.com.

OVERVIEW

The Radial ProAV2 is a two channel (stereo) passive direct box. This innovative DI

features a ‘Swiss army knife’ compliment of connectivity 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 a stereo instrument or two mono ones. Stereo RCA and

3.5mm jacks make it easy to connect -10dB audio devices like MP3 and CD players

to a microphone snake and console preamp.

At the heart of the ProAV2 are two Radial transformers that perform level and imped-

ance conversion while isolating noise caused by ground loops. Radial transformers

are manufactured for optimum signal transfer and minimal insertion loss, and are

exceptional for their low distortion, ﬂ at frequency response and ability to handle high

input levels. The transformer is sheilded in a mu-metal can for protection against

noise caused by electromagnetic ﬁ elds. It’s heavy-duty, two piece steel enclosure is

well suited for years of touring and rental use. The ProAV2 is completely passive and

does not require any power whatsoever to make it work. Enjoy!

CONNECTING THE ProAV2

Before connecting the ProAV2 make sure the sound system is turned off and all lev-

els 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. Phantom power will not damage the ProAV2 if applied.

ProAV2 BLOCK DIAGRAM

Follow the block diagram from the inputs on the left to the output on the right. A really

cool feature shown in the diagram is all the hi-Z input jacks are paralleled together

in stereo. This makes any hi-Z jack a handy patch point. For example, a CD player

can be connected to the RCA jacks and the signal thru-put by the ¼” jacks to a sub-

mixers line input. The 3.5mm jack could also be used to send the CD signal to a

computer sound card.

¼” JACKS - INSTRUMENTS

Guitar, bass and the output of effect pedals may be connected directly to the ¼” input

jacks. The signal may be thru-put to the players on-stage ampliﬁ er by using the same

channel RCA jack and adaptor.

LIFT (RIGHT CHANNEL ONLY)

If the ProAV2 is used as two mono DIs a situation can arise where one source device

needs a ground path through the ProAV2 but the other source does not. This can

occure when one source is AC powered and the other is not. To accommodate this

the right channel is equipped with a separate ground lift switch labeled LIFT. Devices

powered throught the AC mains should be plugged into the right channel. When the

LIFT switch is depressed the right channel ground is interrupted between the input and

output while the left channel maintains a ground path through the ProAV2.

Mains

Break loop here with

LIFT switch.

The right channel LIFT feature can be used on devices that plug into AC mains power to reduce hum and buzz caused

by ground loops. The dashed line shows the ground loop formed between the AC mains and the signal cable ground.

When connecting stereo instruments, like synthesizers and drum machines, the two ¼”

jacks are used for the left and right channels. The stereo signal may be accessed at the

RCA or 3.5mm jacks and passed to sub-mixers, computer sound cards or on-stage ampli-

ﬁ ers.

RCA & 3.5mm JACKS

Consumer electronics with an unbalanced -10dB output, like CD and MP3 players, may

connect directly to the ProAV2 without cumbersome adaptors through the 3.5mm and

RCA inputs. The unbalanced inputs are paralleled together so any unused jacks may be

used to thru-put the signal to another device like a sub-mixer or recorder.

GROUND

To make grounding as ﬂ exible as possible, the ProAV2 features a GROUND switch

and all connectors are isolated from the chassis to help eliminate noise caused by

ground loops. When the GROUND switch is in its “in” position, pin-1 on the XLR is

disconnected, interrupting the ground on both channels between the input and output.

Interrupting the ground can help in some situations to reduce noise caused by ground

loops.

XLR OUTPUT

Each ProAV2 channel outputs a balanced, 600 Ohm, mic-level signal that is compat-

ible with microphone snakes and mixing console preamps. The output can drive long

cables without appreciably noise or signal loss.

OPTIONAL J-RAK

The optional J-RAK is a high density 2RU rack

shelf for Radial DI’s and splitters that allows up to

8 Radial devices to mount in one neat 19” package.

The DI’s can be mounted with either the input side

or output side facing the front. Ideal for studio or

touring. Constructed of 14 gauge steel with a baked

enamel ﬁ nish.

OPTIONAL J-CLAMP

The optional J-CLAMP can mount a single Radial device to

virtually any surface. Perfect for hiding away inside racks, on

podiums or under tables. Constructed of 14 gauge steel with

a baked enamel ﬁ nish

-15dB PAD

The ProAV2 is equipped with a -15dB input PAD to prevent overload distortion when inter-

facing high output devices like CD players. The PAD reduces the input to the left and right

transformers and will not effect the level at the paralleled jacks.

TRANSFORMER ISOLATION

The Radial transformers convert the hi-Z input signals to a low-Z, mic-level signal. A major

beneﬁ t of using transformers for signal conversion is the isolation the transformer provides

by preventing the ﬂ ow of ground currents between the ProAV2s input and it’s output. This

transformer isolation effectively blocks hum and buzz caused by ground loops.
