Mono 4-Way Switch Instructions
1. Be sure all power and audio is turned off. Remove the top
cover of the AC 23B.
2. Locate the 4-WAY/5-WAY switch (see diagram).
3. Move the switch from the 5-WAY position to 4-WAY.
4. Replace the cover. The AC 23B is now set for Mono 4-Way
Mode. The HIGH-MID OUTPUT duplicates the MID
OUTPUT frequencies with a different low pass setting as
determined by the HIGH-MID / HIGH FREQUENCY
control, and is not normally recommended for use since the
tweeter crossover point will be inaccurate.
This operation must be reversed to operate the unit in
either Stereo 3‑Way or Mono 5‑Way Mode.

3. Moving the header to the SHIP position puts the Low Out-
puts back in stereo, as shipped from the factory.

The mono output is now at Channel 1 LOW OUT.
