Observe the labels screened BELOW the knobs for Mono 4-way operation.
1. POWER SWITCH:
Two guesses.

2. POWER INDICATOR:
When this yellow LED is lit, all output muting circuits are fully"on"
and the unit is ready to operate.
3.
MASTER LEVEL CONTROL:
This controls the overall level of the entire unit in the Mono
configuration, without changing the relative settings of the individual Sub/Low/Mid/High
outputs.
4. SUB-WOOFER LEVEL CONTROL:
This controls the level of signal going to the Sub­
woofer only.
5. SUB-WOOFER MUTE SWITCH:
Removes all signal from the Sub-woofer output when
pressed to the IN position. This eases the system tune-up procedure, as described in Section
111-4.
6. TIME DELAY CONTROL:
This control exists primarily for 3-way applications of the AC 23.
In Sub-woofer applications this control will normally be set to minimum (MIN). Refer to
Section 111-3.
7.
SUB/LOW CROSSOVER FREQUENCY SELECTOR:
This 41-detent selector sets the
crossover frequency between the Sub-woofer and Low frequency drivers. The detents will
assure accuracy and consistency. Refer to Section 111-2 to determine the proper crossover
frequency points for the particular drivers in your system.
8. LOW FREQUENCY LEVEL CONTROL:
This controls the level of signal going to the Low
Frequency driver only.
9. LOW FREQUENCY MUTE SWITCH:
Removes all signal from the Low Frequency output
when pressed to the IN position.
10. LOW FREQUENCY TIME DELAY CONTROL:
This control adds from Oto 2mS of time
delay to the Low Frequency output only. This allows a low frequency driver to be electronically
phase-aligned with a mid frequency driver whose diaphragm is situated BEHIND the low
frequency diaphragm. Refer to Section 111-3 for alignment procedure.
11. LOW/MID CROSSOVER FREQUENCY SELECTOR:
This control sets the crossover
frequency between the Low and Mid frequency drivers. Refer to Section 111-2.
