QUICK START
The AC 22B can be either a Stereo 2-Way or Mono 3-Way
crossover. Labels above the controls refer to the unit being oper-
ated in the 2-Way Stereo mode. Labels below the controls refer to
the unit being operated in the 3-Way Mono mode.
The fact that the AC 22B is a multiple function unit means
the outputs are switched around depending on the SYSTEM
MODE and SUBWOOFER switches on the back of the unit.
To operate the AC 22B in Stereo 2-Way mode, be sure that
the Mode switch is set for STEREO 2-WAY. Follow the labels
above the controls and jacks.
When operated in the Mono 3-Way mode, the switch should
be set in the MONO 3-WAY position. Follow the labels below
the controls and jacks. In Mono 3-Way mode the Channel 1
High Output is unusable. This output is the high-pass-only por-
tion of the midrange filter. The Channel 1 High Level and the
Channel 2 Master Level are also defeated on the front panel.
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” Rane-
Note included with this manual for more information on cabling
and grounding requirements.
NEVER CONNECT ANYTHING EXCEPT AN RS 1 OR
OTHER APPROVED RANE AC POWER SUPPLY TO THE
THING THAT LOOKS LIKE A TELEPHONE JACK ON
THE REAR. This is an AC supply and requires some special at-
tention if you do not have an operational power supply EXACT-
LY like the one that was originally packed with your unit.
