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 LOW LEVEL control is inactive.
3
LOW MUTE:
When pressed to the
in
position, all signal is removed from the LOW Output. °is 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 DELAY
control adds from 0 to 2 ms of time delay to the LOW OUT only. °is allows a low frequency driver to be electroni-
cally 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:
°is 41-detent selector determines the crossover frequency between the LOW and HIGH Out-
puts. °e 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 indicator:
If the power cable is plugged in and this yellow LED is lit, the unit ready to operate.
