SUBWOOFER
(V3000 ONLY)
The subwoofer can be operated in stereo or bridge mono, set the switch to subwoofer position
depending on your application, select the frequency from 20 Hz to 200 Hz via variable frequency
selector.
AMP MODE (STEREO/BRIDGE)
The Amplifier mode should be configured before operation, if you want to change it during perfor-
mance, you must decrease the gain controls to protect the speakers from any popping noise.
THRU
Thru will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the
signal source outputs into the first amplifier’s input, patch from the amplifier’s THRU jacks to the
next amplifier’s input, and so on, daisy-chaining as many amplifiers as there is no excessive level
loss. Is not affected by crossover setting.
GROUND LIFT SWITCH
Applying or lifting the ground switch will change level for background noise and hum, if the noise
level remains the same in either position, better to keep the ground lift switch in the ground position.
This will eliminate 60Hz cycle Hum that is sometimes induced when mounting several units in the
same rack.
