Mono 4-way and 5-way control labels are in these rows
Observe the labels screened below the controls for Mono operation.
1
MASTER LEVEL control:
Sets the overall Level of the entire unit in Mono mode, without changing relative 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. See page Manual-13.
3
SUBWOOFER MUTE switch:
Removes all signal from the Sub Output when pressed to the in position. This eases the system
tune-up procedure, as described on pages Manual-9-14.
4
SUBWOOFER DELAY control:
In Subwoofer applications this control has virtually no effect and will normally be set to MIN
(minimum). Refer to pages Manual-9-12 for alignment procedures.
5
SUB / LOW crossover frequency selector:
This 41-detent selector sets the crossover frequency between the Subwoofer and Low
Outputs. Refer to page Manual-9 to determine the proper setting for your system.
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 Outputs.
0
MID LEVEL control:
Sets the Level of signal going to the Mid Output only.
q
MID MUTE switch:
Removes all signal from the Mid Output when pressed in.
w
MID DELAY control:
Adds from 0 to 2 ms of time Delay to the Mid frequency Output only.
e
MID / HIGH‑MID crossover frequency selector:
Sets the crossover frequency between the Mid and High-Mid Outputs.
*
NOTE: Both the CHANNEL 1 HIGH LEVEL control and CHANNEL 2 MASTER LEVEL control are automatically bypassed when
the AC 23S is switched to “MONO” on the back panel. Adjusting these controls has no effect in the Mono mode.
The HIGH-MID LEVEL control, HIGH-MID MUTE switch, HIGH-MID DELAY control and HIGH-MID / HIGH FREQUENCY
control will have no effect regardless of their settings when the AC 23S is switched to “MONO 4-Way” on the back panel.
r
HlGH‑MID LEVEL control (5‑way only): Set
s the Level of signal going to the High-Mid Output.
t
HlGH‑MID MUTE switch (5‑way only):
Removes all signal from the High-Mid Output when pressed to the in position.
y
HlGH‑MID DELAY control (5‑way only):
Adds from 0 to 2 ms of time Delay to the High-Mid Output only.
u
HlGH‑MID / HIGH crossover frequency selector (5‑way only):
Sets the crossover Frequency between the High-Mid and High
Frequency Outputs.
i
HIGH LEVEL control:
This controls the Level of signal to the High Output only.
o
POWER indicator:
Two choices: on or off. If the power is plugged in and this yellow LED is lit, then the unit ready to operate.
