AC 22B

ACTIVE CROSSOVER

OPERATORS MANUAL

AC 22B CONNECTION

In agreement with IEC and AES/ANSI standards, AC 22B

wiring convention is pin 2 Positive, pin 3 Negative (return),

pin 1 Signal ground (for unbalanced use), with the connector

case or shell tied to chassis ground.

BALANCED OPERATION

Use only when driving from a true balanced source and

driving to a true balanced destination—either transformer

coupled or active drive. Connect the input to pins 2 and 3

with pin 2 positive. Do not connect pin 1. Terminate the

shield to the case or shell. Connect the output to pins 2 and 3

with pin 2 positive. Do not connect pin 1. Connect the shield

to the case or shell.

UNBALANCED OPERATION

Connect the input between pins 2 and 1 with pin 2 positive

and pin 1 Signal ground. Short pin 3 to pin 1. Terminate the

shield to the case or shell. Connect the output between pins 2

and 1 with pin 2 Positive. Leave pin 3 open—do not short it

to pin 1. Connect the shield to the case or shell.

COMBINATION OPERATION

For combined balanced and unbalanced operation, use

whichever half of the above instructions apply for each end.

See the “Sound System Interconnection” RaneNote

included with this manual for more information on cabling

and grounding requirements.

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

operated in the 2-Way Stereo mode. Labels below the controls refer to the unit being operated in the 3-Way Mono mode.

The AC 22B is a fully balanced output version of the popular AC 22 and is equipped with XLR conectors instead of

the standard ¼" TRS jacks. All other features, specifications and operation are identical with the standard model with an

added switch. Where the AC 22 is configured somewhat automatically by using switching jacks, the AC 22B is config-

ured by a SYSTEM MODE switch added to 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 portion of the midrange filter. The Channel 1 High Level and the Channel 2 Master Level are also defeated on the

front panel.

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 attention if you do not have an operational power supply EXACTLY like the one that was originally

packed with your unit.
