input used to connect your instrument to

the 4-Play.

2. SELECT FOOTSWITCH: Advances

through the enabled outputs to select

which one is on.

3. OUTPUT LED INDICATORS: Indicate

which of the 4 outputs is active, super-

bright to ensure visibility on stage.

4. GROUND LIFT: Disconnects the ground

on pin-1 at the XLR outputs.

5. OUTPUTS 1 ~ 4: Balanced XLR mic-

level outputs are used to feed the PA

system.

6. MUTE FOOTSWITCH: Used to turn

off all of the balanced outputs for

changeovers and tuning.

7. MUTE LED: Illuminates when the mute

footswitch is depressed.

8. TUNER OUT: Connect to a tuner pedal

to allow for on-the-fly tuning.

9. TUNER ASSIGN: Selects whether the

tuner is always on, only on when the

mute switch is engaged, or only on when

the mute switch is not engaged.

10. OUT-3 ENABLE: Allows out-3 to be

activated using the select switch.

11. OUT-4 ENABLE: Allows out-4 to be

activated using the select switch.

OVERVIEW

At its most basic form, the 4-Play is a

1-in, 4-out direct box that lets you route

the connected instrument to any of four

different channels on the PA and in your

monitors. This allows each instrument to

have its own dedicated channel with in-

dividual level, EQ and effects. Only one

input is used in order to eliminate cable

spaghetti on stage. You simply mute the

4-Play, change the instrument, select

the desired output and you are set to go.

MAKING CONNECTIONS

Before making connections, it is always best to turn audio system levels down in order to prevent

plug-in transients that could damage more sensitive components such as high frequency drivers. It

is also a good idea to test at low volumes before turning up. This way, should a cable not be properly

seated, making a live connection will be safer.

Powering the 4-Play is done using a standard

9V Boss®-type power supply. These are readily

available at all music stores. You can also power

the 4-Play using a multi-output pedal brick. Be

careful to ensure you are using the proper volt-

age and polarity (center-pin negative). A power

supply cable lock is there to protect against ac-

cidental disconnection. Merely unscrew the lock

using a hex driver, insert the power cable through

the cavity and then retighten.

Connections from instruments to the 4-Play in-

put is done using standard ¼” coaxial cables.

The outputs from the 4-play to the PA system

are typical XLR connections wired to AES stan-

dard pin-1 (ground), pin-2 (+) and pin-3 (-).

USING

There is no power switch on the 4-Play. As soon as you connect the PSU it will spring to life and OUT-

1 will be activated. The OUT-1 LED will illuminate to conrm the active output.

If all is good, mute the 4-Play and connect OUT-2 to

your second channel. You can test using the same in-

strument or switch to another if you like. Depressing the

SELECT footswitch will now toggle between outputs 1

and 2. If you plan to use OUT-3 and OUT-4, these must

be enabled using the two ‘set & forget’ switches located

on the front corners. When pushed in, these switches al-

low the selector switch to advance to the third and fourth

outputs and illuminate the associated LEDs.

Note: There are two ‘set & forget’ switches on the two front corners. These are used to enable selec-

tion of outputs 3 and 4 respectively. For now, these should be set in the out position.

1. Press the MUTE footswitch to turn off the outputs.

2. The MUTE LED will illuminate to let you know the outputs are muted.

3. Connect your rst instrument to the 4-Play using a standard ¼” coaxial guitar cable.

4. Connect OUT-1 to the rst channel on your PA system via XLR cable.

5. Depress the MUTE footswitch to reactivate the outputs and slowly increase the level on the PA

to test.

FEATURES

Lifting the ground

The 4-Play is equipped with ground lift switches on each of the four out-

puts. Set all of the ground lift switches in the down or grounded position. As

you rotate through the outputs, if you notice any noise, try lifting the ground

as this can often help remove buzz and hum caused by ground loops.

Connecting a tuner

The 4-Play is also equipped with a tuner output, along with a 3-position

tuner assign switch that allows you to choose when this output is active.

When the tuner assign is set to ALWAYS ON, the tuner will still be active

even when the mute switch is engaged. When set to ON W MUTE, the

tuner output will only be active when the mute switch is engaged, allowing

you to mute the instrument output to the PA when you want to tune up. The

OFF W MUTE setting will do the opposite, allowing the tuner to remain on

until the mute switch is engaged.

You can also use

the TUNER OUT

as an output to an

amp. Select OFF W

MUTE when switching

instruments.
