FEATURES

1. JR1 REMOTE: Locking XLR

and ¼" combo jack used to

connect a remote switch. Use with

footswitches, MIDI contact closures

or the Radial JR1.

2. REMOTE LINK: Used to link

the switching of additional Relay

Xo units. Allows stereo and multi-

channel switching systems.

3. MIC/LINE INPUT: Balanced XLR

input. The Relay Xo signal path is

100% passive. Audio signals will

pass through unchanged without

added noise or distortion.

4. OUTPUT-B: Alternate balanced

XLR output. This output is active

when the select switch is pressed

inward or when a remote switch is

closed. The B LED illuminates when

the output is active.

5. OUTPUT-A: Main balanced XLR

output. This output is active when

the switch is in the outward position

or when a remote switch is open.

The A LED illuminates when the

output is active.

6. CA BL E CLA MP : Prevents

accidental power disconnection by

locking down the AC adapter cable.

7. POWER JACK: Connection for

the included 15 volt (400mA) AC

power adapter

8. FULL-BOTTOM NO-SLIP PAD:

This provides electrical isolation

and plenty of ‘stay-put’ friction to

keep the Relay Xo in one place.

9. OUTPUT SELECT: This switch

toggles the Relay Xo’s outputs.

Two LED indicators display which

output is active.

10. GROUND LIFT: Disconnects

pin-1 (ground) on the input XLR

jack to help reduce hum and buzz

caused by ground loops.

Tip

OVERVIEW

Thank you for purchasing the Radial Relay Xo, a simple yet effective switching

device designed to toggle a microphone or other balanced audio signal

between two channels on a PA system. As with all products, getting to know

the feature set is essential if you intend to get the most out of the Relay.

Please take a minute to read through this short manual. If you are left with

unanswered questions, feel free to send us an email at info@radialeng.com

and we will do our best to reply in short order. Now get ready to remotely

switch to your heart’s content!

The Relay is basically a 1-in, 2-out straight-wire switcher for balanced audio.

There is no transformer or buffering circuitry in between the input and outputs.

This means the Relay Xo can not introduce distortion or noise into the source

signal and allows it to be used with mic or line level sources. A link feature

allows multiple Relay Xo units to be combined and switch stereo or multi-

channel audio systems. Switching can be done on the Relay Xo, via remote

footswitch or by MIDI contact closure.

MAKING CONNECTIONS

Before making any connections, make sure volume levels are turned off or

down and/or power is turned off. This will help you avoid turn-on or power-on

transients that could harm more sensitive components like tweeters. There

is no power switch on the Relay. Simply plug in the included 15 VDC supply

and it will spring to life. A cable clamp next to the power jack can be employed

to prevent accidental disconnection.

The audio input and outputs employ balanced XLR connections wired to the

AES standard with pin-1 ground, pin-2 hot (+), and pin-3 cold (-). Connect

your source device such as a microphone or wireless mic receiver to the

Relay Xo input jack. Connect the A and B outputs to two inputs on a mixer.

A B

Switching between the outputs can be done using the OUTPUT SELECT push

button on the side panel. Start by setting up channel-A. Set the AB selector

switch set to the A position (outward). Speak into the mic while slowly bringing

up the volume levels. To set up the channel-B depress the AB selector switch

to toggle the output. The LED indicators illuminate to display the active output.

USING THE RELAY XO FOR A TALK-BACK SYSTEM

A momentary footswitch, like the optional JR1M, is recommended when using

the Relay Xo as a talk-back or communication mic switcher as this requires

holding the footswitch ‘on’ to speak with other band members or the crew.

Releasing the footswitch reverts back to normal. This avoids accidentally

leaving the Relay on ‘communication mode’ which could otherwise prove to

be embarrassing if left on.

USING THE RELAY XO TO SWITCH MIXER CHANNELS

Using a latching switch, like the optional JR1L, is suggested when switching

between audio channels on a PA system. Switching channels lets you

alternate between a dry channel for communication with the audience and

a wet channel with echo and reverb for singing.

REMOTE CONTROL

The Relay Xo’s outputs may be toggled remotely using an external ‘latching’ or

‘momentary’ switch connected to the ‘JR1 REMOTE’ jack. This combo jack features

a locking XLR and ¼" input. The ¼" connection works with any standard footswitch

such as a momentary sustain pedal or a latching amplier channel switch. It can also

work with any device equipped with a ¼" contact-closure output like a MIDI controller.

Simple footswitches and contact-closure devices like MIDI

controllers use ¼" cables to connect to the Relay Xo.

Both the combo jack’s XLR and ¼" connection work with the optional Radial JR1

footswitches. The JR1 footswitches are also equipped with locking XLR jacks allowing

you to use either type of cable. Locking connectors are benecial on busy stages as

it reduces the opportunity for a connection to come lose during a performance. The

JR1 footswitches are available in momentary (JR1-M) or latching (JR1-L) formats to

address various needs on stage and include A/B LED status indicators.

The JR1 uses either ¼" or locking XLR cable to connect to the Relay Xo.

Because footswitches are either momentary or latching it’s important to understand

how the Relay Xo works with these two types of switches. A momentary

footswitch, like the JR1-M or a keyboard sustain pedal, will toggle to output-B

only while held down. Once the momentary footswitch is released the Relay Xo

will toggle back to output-A. A latching footswitch , like the JR1L or an amplier

AB channel selector switch will toggle the Relay each time it is pressed. One press

will toggle to output-B. Pressing again with toggle back to output-A.

MULTI-CHANNEL SWITCHING

Two or more Relay Xo units can be switched in tandem by simply bridging the

devices together using a standard ¼" patch cable. The LINK feature allows

switching of stereo and multi-channel audio systems from a single switch. Connect

a footswitch to the rst unit or use the side panel OUTPUT SELECT switch.

Connect the ¼" LINK jack on the rst unit to the JR1 REMOTE jack on the second.

You can connect as many successive units as you like this way.
