FRONT PANEL: MONO 3-WAY CONFIGURATION
Observe the labels
below
the controls for Mono operation.
1. POWER switch: Self-evident.
2. POWER indicator: When this yellow LED is lit, the unit is ready to operate.
3. CHANNEL 1 MASTER LEVEL: This controls the overall Level without altering the relative settings of the HIGH, MID
and LOW Outputs. Unity gain for all Level controls is at “7”.
4. LOW LEVEL: This controls the Level of signal going to the LOW Output.
5. LOW MUTE: When pressed to the in position, all signal is removed from the LOW Output. This eases tune-up procedure,
as described on pages Manual 7-13.
6. LOW DELAY: This control adds from 0 to 2 ms of time Delay to the LOW Output only. This allows a low frequency driver
to be electronically phase-aligned with a high frequency driver whose diaphragm is situated behind the low frequency
diaphragm. Refer to Time Delay Adjustment on page Manual-6 for the procedure.
7. LOW/MID FREQUENCY: This 41-detent selector determines the crossover Frequency between LOW and MID Outputs.
The detents will assure maximum accuracy and consistency between Channels. Refer to Selecting Crossover Frequencies
on page Manual-6 to determine proper setting for your particular system.
8. MID LEVEL: This controls the Level of signal going to the MID Output.
* NOTE: The Channel 2 MASTER LEVEL control is automatically bypassed internally when the System Mode switch is set to
MONO 3-WAY as shown on the facing page. Adjusting this control will have no effect in the MONO mode.
9. MID MUTE: When pressed to the in position, all signal is removed from the MID Output. This eases tune-up procedures, as
described in pages Manual 7-13.
10. MID DELAY: This control adds from 0 to 2 ms of time Delay to the MID Output only. This allows a mid frequency driver
to be electronically phase-aligned with a high frequency driver whose diaphragm is situated behind the mid frequency
diaphragm. Refer to Time Delay Alignment on page Manual-6 for procedure.
11. MID/HI FREQUENCY: This sets the crossover Frequency between the MID and HIGH Outputs. Refer to Selecting
Crossover Frequencies on page Manual-6.
12. HIGH LEVEL: This controls the Level of signal going to the HIGH Output only.
