FRONT PANEL: MONO 3-WAY CONFIGURATION
Observe the labels below the controls for Mono operation.
1
CHANNEL 1 MASTER LEVEL 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”.
2
LOW LEVEL controls the Level of signal going to the LOW Output.
3
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 7-12.
4
LOW DELAY 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.
5
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.
* NOTE: The Channel 1 HIGH LEVEL and Channel 2 MASTER LEVEL controls are automatically bypassed when the System Mode
switch is set to MONO 3-WAY as shown on the facing page. Adjusting these controls have no effect in MONO mode.
6
MID LEVEL controls the Level of signal going to the MID Output.
7
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 7-12.
8
MID DELAY control adds from 0 to 2 ms of time Delay to the MID Output only. This allows a mid frequency driver to be elec-
tronically 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.
9
MID / HIGH FREQUENCY: sets the crossover Frequency between the MID and HIGH Outputs. Refer to Selecting Cross-
over Frequencies
on page Manual-6.
0
HIGH LEVEL controls the Level of signal going to the HIGH Output only.
