FRONT PANEL: STEREO 2-WAY CONFIGURATION
Observe the labels screened above the controls for stereo operation.
1
CHANNEL 1 MASTER LEVEL controls the overall Level of Channel 1 without altering the relative settings of the HIGH 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 in this Channel. In the MONO SUB mode the Channel 1
LEVEL control sets the Level of the MONO SUB Output, Channel 2's LEVEL control is inactive.
3
LOW MUTE: When pressed to the in position, all signal is removed from the LOW Output. This eases tune-up procedures, as
described on pages Manual-7 through 12. In the MONO SUB mode, the Channel 1 LOW MUTE switch mutes the MONO
SUB Output, Channel 2's MUTE is inactive.
4
LOW TIME DELAY control adds from 0 to 2 ms of time Delay to the LOW OUT 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. NOTE: Both DELAY controls are inactive in the MONO SUB mode.
5
LOW / HIGH FREQUENCY: This 41-detent selector determines the crossover Frequency between the LOW and HIGH Out-
puts. The detents assure maximum accuracy and consistency between Channels. Refer to Selecting Crossover Frequencies on
page Manual-6 to determine the proper setting for your particular system.
6
HIGH LEVEL controls the Level of signal going to the HIGH Output in this Channel.
7
CHANNEL 2 MASTER LEVEL controls the overall Level of Channel 2 without altering relative settings of the HIGH and
LOW Outputs.
8
POWER switch and indicator: Two choices: on or off. If the power supply is plugged in, this yellow LED is lit, and the POW-
ER button is depressed, then the unit ready to operate.
