REAR PANEL: MONO 3-WAY INSTALLATION

CAUTION: MONO SUB SWITCH MUST BE IN 2-CHANNEL OR M3W MODE!

 

Mono (CHANNEL 1) INPUT: This ¼" Input accepts either balanced TRS (tip-ring-sleeve) or unbalanced TS (tip-sleeve)

plugs. Plug the output of the mixer, equalizer or other signal source to this Input for mono operation. DO NOT PLUG INTO
THE CHANNEL 2 INPUT: THAT INPUT IS USED TO DRIVE TWO CHANNELS WITH THE SAME MONO INPUT.
 Refer
to “Stereo 2-Way Installation” on page Manual-3.

* NOTE: Do not use this input for 3-Way Mono operation. Use the Channel 1 Input only.

 

HIGH frequency OUTPUT: These are ¼" TS (tip-sleeve) unbalanced Output jacks. Connect this Output to the input of the

high frequency amp.

 

MID frequency OUTPUT: Connect this Output to the input of the mid frequency amp.

 

LOW frequency OUTPUT: Connect this Output to the input of the low frequency amp.

 

MONO SUB mode switch: must be in the M3W position for Mono 3-Way operation.

 

Power input connector: This unit is supplied with a Rane RS 1 remote power supply suitable for connection to this input

jack. This unit’s power supply input is designed for an AC supply, delivering 18-24 volts, from a center-tapped transformer
capable of supplying at least the current demanded by this product. Using any other type of supply may damage the unit and
void the warranty. Consult the factory for replacement.

 

Chassis ground point: A #6-32 screw is supplied for chassis grounding purposes. Always connect crossover chassis ground

to amplifier chassis ground. See the CHASSIS GROUNDING note on page Manual-3.
