REAR PANEL: STEREO 2-WAY INSTALLATION
Observe the labels
above
the Inputs and Outputs for Stereo operation.
햲
CHANNEL 1 INPUT:
Plug the left output of the mixer, equalizer or other signal source to this Input. See ‘AC 23B
Connection’ on page Manual-1 for wiring details.
햳
CHANNEL 2 INPUT:
Plug the right output of the mixer, equalizer or other signal source to this Input.
.
햴
HIGH FREQUENCY OUTPUTS:
Connect the CHANNEL 1 HIGH OUT to the left channel input of the high frequency
amp, and the CHANNEL 2 HIGH OUT to the right channel input of the high frequency amp.
햵
LOW FREQUENCY OUTPUTS:
Connect the CHANNEL 1 LOW-2Way Output to the left channel input of the low
frequency amplifier, and the CHANNEL 2 LOW-2Way Output to the right channel input of the low amplifier. If you need a
summed Mono Low Ouput, see ‘Monoing the Low Outputs’ on page Manual-7.
햶
2-Way/3-Way switch:
Converts the outputs from 3-Way to 2-Way. This switch removes the Low frequency crossover from
the signal path. Low frequencies are now routed to the Mid frequency Output. Be sure to slide the switches to the 2-Way
position.
Note: The Low frequency outputs are still active and may be used as additional subwoofer outputs.
햷
STEREO/MONO switch:
Set this switch to the STEREO “out” position.
햸
POWER input connector:
Use only a model RS 1 or other power supply approved by Rane.
This unit is supplied with a
remote power supply suitable for connection to this input jack. This is not a telephone jack. The power requirements call for
an 18-24 VAC center-tapped transformer only. Using any other type of unapproved supply may damage the unit and void
the warranty. Two years parts and labor is worth safeguarding.
햹
Chassis ground point:
A #6-32 screw is used for chassis grounding purposes. Always connect crossover chassis ground to
amplifier chassis ground. See ‘Chassis Grounding’ below for details.
IMPORTANT NOTE
CHASSIS GROUNDING
If after hooking up your system it exhibits excessive hum or buzzing, there is an incompatibility in the grounding
configuration between units somewhere. Your mission, should you accept it, is to discover how your particular system
wants to be grounded. Here are some things to try:
1. Try combinations of lifting grounds on units that are supplied with ground lift switches or links.
2. If your equipment is in a rack, verify that all chassis are tied to a good earth ground, either through the line cord ground-
ing pin or the rack screws to another grounded chassis.
3. Units with outboard power supplies do not ground the chassis through the line cord. Make sure that these units are
grounded either to another chassis which is earth grounded, or directly to the grounding screw on an AC outlet cover by
means of a wire connected to a screw on the chassis with a star washer to guarantee proper contact.
4. Try moving the device away from high magnetic field sources, such as large transformers used in power amplifiers.
Please refer to the included RaneNote “Sound System Interconection” for further information on system grounding.
