settings of the individual Sub/Low/Mid/High Outputs. Unity gain for all level controls is "7".
2.
Subwoofer Level Control: Sets the level of signal going to the Sub Output.
3.
Subwoofer Mute Switch: Removes all signal from the Sub Output when pressed to the in position.
4.
Subwoofer Delay Control: In Subwoofer applications this control has virtually no effect and will normally be
set to MIN (minimum).
5.
Sub / Low Crossover Frequency Selector: This selector sets the crossover frequency between the
Subwoofer and Low outputs.
6.
Low Level Control: Sets the Level going to the Low frequency output.
7.
Low Mute Switch: Removes all signal from the Low output when pressed in.
8.
Low Delay Control: Adds from 0 to 2 ms of time delay to the Low output only.
9.
Low / Mid Crossover Frequency Selector: Sets the crossover frequency between the Low and Mid

Frequency control will have no effect regardless of their settings when the AC 23S is switched to "Mono 4W"
on the back panel.

High-Mid Level Control (5-way only): Sets the level of signal going to the High-Mid output.
15.
High-Mid Mute Switch (5-way only): Removes all signal from the High-Mid output when pressed to the in
position.
16.
High-Mid Delay Control (5-way only): Adds from 0 to 2 ms of time delay to the High-Mid output only.
17.
High-Mid / High Crossover Frequency Selector (5-way only): Sets the crossover frequency between the
High-Mid and High Frequency outputs.
