REAR PANEL: ALTERNATE MONO 4-WAY INSTALLATION
Note: The switching in the AC 23B will result in a Mono 4-Way configuration with the crossover ranges SUB,
LOW, MID & HIGH from left to right across the front panel. By connecting a patch cable from the CHANNEL
1 HIGH OUT to the CHANNEL 2 INPUT, the LOW/MID crossover range changes from 70 Hz-1 kHz to a higher
range of 190 Hz-7 kHz. Switch CHANNEL 1 to 3-Way, and CHANNEL 2 to 2-Way.
Note: DO NOT follow the Mono 4-Way Jumper Instructions on page Manual-7.
ቢ MONO INPUT: Connect the output from your mixer or other signal source only to the CHANNEL 1 INPUT for Mono
operation; do not use the Channel 2 Input. Note: For this alternate Mono 4-Way installation, connect a patch cord from the
CHANNEL 1 HIGH OUT to the CHANNEL 2 INPUT as shown.
ባ SUBWOOFER OUTPUT: Connect the SUB OUT to the input of the subwoofer amplifier (or bass bin amp).
ቤ LOW FREQUENCY OUTPUT: Connect the MID OUT to the input of the low frequency amplifier.
ብ MID FREQUENCY OUTPUT: Connect the HI MID OUT to the input of the mid frequency amplifier. Be sure the
CHANNEL 1 HIGH LEVEL and the CHANNEL 2 MASTER LEVEL controls are set at “7” for unity gain between Channels.
ቦ Hl FREQUENCY OUTPUT: Connect the HIGH OUT to the input of the high frequency amplifier.
ቧ STEREO-MONO switch: Be sure this switch is in the STEREO out position. Yes, STEREO. A Mono circuit is created
when Channel 1 is patched into Channel 2, and the correct signal flow depends on this switch.
ቨ 2-WAY/3-WAY switches: Converts each channels outputs from 3-Way to 2-Way. For this configuration, set CHANNEL 1
to 3-Way, and CHANNEL 2 to 2-Way.
ቩ 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.
ቪ Chassis ground point. A #6-32 screw is used for chassis grounding purposes. Always connect the crossover chassis to the
amplifier chassis. See the CHASSIS GROUNDING note on page Manual-7 for details.
