QUICK START
e AC 22S can be either a Stereo 2-Way or Mono 3-Way crossover. To keep operation simple, remember this:
Labels above the controls refer to the 2-Way Stereo mode.
Labels below the controls refer to the 3-Way Mono mode.
e fact that the AC 22S 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 22S 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.
AC 22S
ACTIVE CROSSOVER
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. is output is the high-pass-only portion of the midrange filter. e 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 22S
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.
WEAR PARTS: is product contains no wear parts.

2-way operation:
read the top row
Observe the labels screened above the controls for stereo operation.
1 CHANNEL 1 MASTER LEVEL controls the overall Level of Channel 1 without altering the relative settings of the HIGH and
LOW Outputs. Unity gain for all LEVEL controls is at “7”.
2 LOW LEVEL controls the Level of signal going to the LOW Output in this Channel. In the MONO SUB mode the Channel 1
LEVEL control sets the Level of the MONO SUB Output, Channel 2's LOW LEVEL control is inactive.
3 LOW MUTE: When pressed to the in position, all signal is removed from the LOW Output. is eases tune-up procedures, as
described on pages Manual-7 through 12. In the MONO SUB mode, the Channel 1 LOW MUTE switch mutes the MONO
SUB Output, Channel 2's MUTE is inactive.
4 LOW DELAY control adds from 0 to 2 ms of time delay to the LOW OUT only. is allows a low frequency driver to be elec-
tronically phase-aligned with a high frequency driver whose diaphragm is situated behind the low frequency diaphragm. Refer to
Time Delay Adjustment on page Manual-6. NOTE: Both DELAY controls are inactive in the MONO SUB mode.
5 LOW / HIGH FREQUENCY: is 41-detent selector determines the crossover frequency between the LOW and HIGH Out-
puts. e detents assure maximum accuracy and consistency between Channels. Refer to Selecting Crossover Frequencies on
page Manual-6 to determine the proper setting for your particular system.
6 HIGH LEVEL controls the Level of signal going to the HIGH Output in this Channel.
7 CHANNEL 2 MASTER LEVEL controls the overall Level of Channel 2 without altering relative settings of the HIGH and
LOW Outputs.
8 POWER indicator: If the power cable is plugged in and this yellow LED is lit, the unit ready to operate.

Observe the labels screened above the Inputs and Outputs for stereo operation.
1 CHANNEL 1 INPUT connects to the left channel output of the mixer, equalizer or other source.
2 CHANNEL 2 INPUT connects to the right channel output of the mixer, equalizer or other source.
3 HIGH OUTPUTS: Connect 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.
4 LOW OUTPUTS: Connect the Channel 1 LOW OUT to the left channel input of the low frequency amp and the Channel 2
LOW OUT to the right channel input of the low frequency amp. When the SUBWOOFER switch is set to MONO SUB, only
use Channel 1 LOW OUT. Channel 2 LOW OUT is disconnected in MONO SUB mode.
5 SUBWOOFER switch disconnects the Output from Channel 2 LOW OUT and sums it with Channel 1 LOW OUT. e result
is taken from the Channel 1 LOW OUT.
6 MODE switch: Set this switch for STEREO 2-WAY operation.
7 Universal Voltage Input: via a miniature IEC 60320 C6 appliance inlet. is mates with an IEC 60320 C5 line cord (USA
domestic). Do not lift the ground connection!

3-way operation:
read the bottom row
Observe the labels below the controls for Mono operation.
1 CHANNEL 1 MASTER LEVEL controls the overall Level without altering the relative settings of the HIGH, MID and LOW
Outputs. Unity gain for all Level controls is at “7”.
2 LOW LEVEL controls the Level of signal going to the LOW Output.
3 LOW MUTE: When pressed to the in position, all signal is removed from the LOW Output. is eases tune-up procedure, as
described on pages Manual 7-12.
4 LOW DELAY control adds from 0 to 2 ms of time Delay to the LOW Output only. is allows a low frequency driver to be
electronically phase-aligned with a high frequency driver whose diaphragm is situated behind the low frequency diaphragm. Refer
to Time Delay Adjustment on page Manual-6 for the procedure.
5 LOW / MID FREQUENCY: is 41-detent selector determines the cross over Frequency between LOW and MID Outputs. e
detents will assure maximum accuracy and consistency between Channels. Refer to Selecting Crossover Frequencies on page
Manual-6 to determine proper setting for your particular system.
* NOTE: e Channel 1 HIGH LEVEL and Channel 2 MASTER LEVEL controls are automatically bypassed when the System Mode
switch is set to MONO 3-WAY as shown on the facing page. Adjusting these controls have no effect in MONO mode.
6 MID LEVEL controls the Level of signal going to the MID Output.
7 MID MUTE: When pressed to the in position, all signal is removed from the MID Output. is eases tune-up procedures, as
described in pages Manual 7-12.
8 MID DELAY control adds from 0 to 2 ms of time Delay to the MID Output only. is allows a mid frequency driver to be elec-
tronically phase-aligned with a high frequency driver whose diaphragm is situated behind the mid frequency diaphragm. Refer to
Time Delay Alignment on page Manual-6 for procedure.
9 MID / HIGH FREQUENCY: sets the crossover Frequency between the MID and HIGH Outputs. Refer to Selecting Cross-
over Frequencies on page Manual-6.
0 HIGH LEVEL controls the Level of signal going to the HIGH Output only.
q POWER switch and indicator: If the power cable is plugged in and this yellow LED is lit, the unit ready to operate.
