FRONT PANEL: STEREO 2-WAY CONFIGURATION

Observe the labels ABOVE the controls for Stereo operation.

 

POWER switch: Self-evident.

 

POWER indicator: When this yellow LED is lit the unit is ready to operate.

 

CH 1 MASTER LEVEL control: sets the overall level of Channel 1 without altering the relative settings of the HI and

LOW outputs. Unity gain for all level controls is at “7”.

 

LOW frequency LEVEL control: sets the level of signal going to the Low Output in this Channel. Refer to alignment

instructions on page Manual-11. In the MONO SUB mode the Channel 1 LEVEL control sets the Level of the mono
subwoofer output; Channel 2's LEVEL control is inactive.

 

LOW frequency MUTE switch: When pressed to the in position, all signal is removed from the Low Output in this

Channel. This eases tune-up procedures as described on page Manual-6. In the MONO SUB mode, the Channel 1 LOW
MUTE switch Mutes the MONO SUB Output, Channel 2's Mute is inactive.

 

LOW frequency time 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. NOTE: Both DELAY controls are inactive in the MONO SUB mode. See instructions on page Manual-6.

 

Crossover frequency selector: This 41-detent selector determines the crossover frequency between Low and High fre-

quency Outputs. The detents assure maximum accuracy and consistency between channels. Refer to page Manual-6 to
determine the proper crossover frequency for your particular system.

  

HIGH frequency LEVEL control: sets the Level of signal going to the High Frequency Ouput in this Channel.

 

CH 2 MASTER LEVEL control: sets the overall Level of Channel 2 without altering relative settings of the HIGH and

LOW Outputs.

Observe the labels ABOVE the inputs and outputs for Stereo operation.
