Labels above the controls refer to the unit being operated in the 2- or 3-Way Stereo mode. Labels below the
controls refer to the unit being operated in the 4- or 5-Way Mono mode.
Set the STEREO/MONO switch appropriately. The fact that the AC 23B is a multiple function unit means the outputs
are switched around in Mono mode.
To operate the unit in Stereo 3-Way mode, be sure the rear panel switches are set for STEREO 3-WAY. Following the
labels above the controls and jacks in logical order, you will find Channel 1 Master Input LEVEL, LOW Output, MID
Output, and HIGH Output, with the same for Channel 2. If you need a summed Mono Low Ouput, see 'Monoing the Low
Outputs' on page Manual-7.
To use the unit as a Mono 5-Way, first check that the CHANNEL 1 and 2 switches are set to 3-WAY, and the other
switch is set to MONO. Connect the INPUT source to CHANNEL 1 only. Following the labels below the jacks, look at
SUB OUT, then look over at LOW OUT, now go back to MID OUT, then over to HIGH-MID OUT and then proceed to
the HIGH OUT. An internal switch determines 4 or 5-Way mode. Our apologies to 4-Way users: We must ship the units in
the 5-Way mode since normal Stereo 3-Way operation demands it: a fact not the least bit obvious, but nevertheless, a fact
it remains. Pity. See page Manual-6 for Mono 4-Way configuration.
In agreement with IEC and AES/ANSI standards, AC 22B wiring convention is pin 2 Positive, pin 3 Negative (return),
pin 1 chassis ground. See the "Sound System Interconnection" RaneNote included with this manual for more information
on cabling and grounding requirements.
CAUTION: Never connect anything except an approved Rane Power supply to the thing that looks like a red
telephone jack on the rear of the AC 23B. This is an 18 VAC center tapped power input. Consult the Rane factory for a
replacement or substitution.
WEAR PARTS: This product contains no wear parts.
