CONGRATULATIONS

on your purchase of the Radial ProAV1 passive direct box. This innovative DI fea-

tures a ‘Swiss army knife’ compliment of connectivity options making the PROAV1

the perfect DI for professional AV integrators and rental companies that regularly

deal with a variety of system interface problems. As with all Radial products the

ProAV1 is easy to use. This short manual contains all the information you need to

start using the ProAV1 right away. For more information on the ProAV1 and other

Radial products, visit our website at www.radialeng.com.

The Radial ProAV1 is a clever and useful device that will provide you with years of

problem-solving connectivity. It may even save the show ten minutes before curtain.

Enjoy!

INTRODUCTION

The ProAV1 is a single channel DI with stereo inputs and a merge function that

mixes left and right signals to a mono, mic-level, 600 Ohm XLR output. Upon in-

spection, you will notice the Radial ProAV1 is equipped with multiple input connector

formats that allow virtually any audio device to be connected. In addition to standard

¼” instrument inputs, the ProAV1 is equipped with 3.5mm and RCA jacks for -10dB

consumer audio devices like MP3 and CD players. An XLR jack allows +4dB line-

level pro-audio equipment to be properly connected to a microphone snake and

console preamp.

At the heart of the ProAV1 is the Radial transformer that balances the signal and

provides level and impedance conversion while isolating noise caused by ground

loops. Radial transformers, manufactured for optimum signal transfer and minimal

insertion loss, are exceptional for their linear frequency response and ability to han-

dle high input levels without distortion. The transformer is mounted in a mu-metal

can for protection against electromagnetic ﬁ elds produced by power transformers,

lighting dimmers and video displays.

The ProAV1 is completely passive and therefore does not require any power what-

soever to make it work. With its heavy-duty steel construction the ProAV1 is well

suited for touring and rental use.

CONNECTING THE ProAV1

Before connecting the ProAV1 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 cause

damage to speakers. Also conﬁ rm that the PAD, LIFT and XLR INPUT SELECT but-

tons are in their “out” positions. Phantom power will not damage the ProAV1.

ProAV1 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 the hi-Z input jacks are paralleled together in stereo. This

makes any unused hi-Z jack a handy patch point to pass the signal on to mixers or ampli-

ﬁ ers. Next, the stereo inputs are merged to mono through a resistive network designed to

minimize phase cancellation.

-15dB PAD

The ProAV1 is equipped with a -15dB input PAD to prevent overload distortion when

interfacing high output devices like CD players. The PAD reduces the input to the

transformer and will not effect the level at the thru-put jacks. The XLR input is preset

for +4dB signals and is not affected by the PAD.

TRANSFORMER ISOLATION

The ProAV1 transformer converts hi-Z inputs to a low impedance, balanced, mic-level

signal. A huge beneﬁ t of using transformers for signal conversion is the isolation the

transformer provides by preventing the ﬂ ow of ground currents between the input and

output. This isolation effectively blocks hum and buzz caused by ground loops.

GROUND LIFT

To make grounding as ﬂ exible as possible the ProAV1 features a ground LIFT switch.

When the LIFT switch is in the “in” position, pin-1 on the XLR output is disconnected,

interrupting the ground between the source device and mixing console. This can help

to reduce noise caused by ground loops.

XLR OUTPUT

The ProAV1 produces a balanced, 600 Ohm, mic-level signal that is compatible with

microphone snakes systems and mixing consoles preamps. Balanced signals can

drive very long cables without appreciable noise or signal loss.

ACCESSORIES

OPTIONAL J-RAK

The optional J-RAK is a 2RU rack

chassis that allows up to 8 Radial

devices in one neat 19” package. The

DIs can be mounted with either the input

side or output side facing the front.

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.

RCA & 3.5mm JACKS - CONSUMER -10dB AUDIO EQUIPMENT

Consumer audio electronics like CD players, computer sound cards and MP3 players

may connect directly to the ProAV1 without cumbersome adaptors through the 3.5mm

and RCA inputs.

¼” JACKS - INSTRUMENTS

Musical instruments may be connected to the ¼” input jacks. When connecting a mono

instrument, like a bass guitar, the instrument connects to the ¼” INPUT jack and the play-

ers on-stage ampliﬁ er is connected to the ¼” THRU jack.

When connecting stereo instruments, like sythesizers, the two ¼” jacks may be used for

left and right channels. The signal may be accessed at the RCA THRU or 3.5mm jacks

and passed to mixers, sound cards or on-stage ampliﬁ ers.

XLR BALANCED +4dB INPUT

Pro-audio equipment with a balanced +4dB line output may be connected to the ProAV1

XLR input. The XLR input is activated by a recessed switch on the side of the ProAV1.

Push the recessed switch in to activate the XLR input and disable the ¼”, 3.5mm and

RCA inputs. The ProAV1 will convert the +4dB line input to a mic-level signal at the XLR

output.

Computer sound card uses 3.5mm jack. RCA jacks output stereo

signal to local mixer. Mono mic-level output to PA system.
