  • Page 9 5 HlGH‑MID OUTPUT (FOR MONO 5‑WAY ONLY): Use this Output only for Mono 5-Way applications. Connect the HIGH-MID OUT to the input of the high-mid frequency amplifier. Do not use this Output when using the AC 23S as a Mono 4-Way Crossover.
  • Page 10 Mid Amp Sub Amp The switching in the AC 23S will result in a Mono 4‑Way configuration with the crossover ranges SUB, LOW, MID & HIGH from left to right across the bottom front panel. By connecting a patch cable from the CHANNEL 1 HIGH OUT to the CHANNEL 2 INPUT, the LOW / MID crossover range changes from 70 Hz‑1 kHz to a higher range of 190 Hz‑7 kHz.
