Audio Adjustment
The line level input of the loudspeaker expects to see -10 dBV nominal, the level provided by many consumer audio
devices. Higher input levels may be used or the volume of the loudspeaker may be turned down by adjusting the
attenuator behind the end cap as shown below. The DIP switch #1 is used to select between stereo or mono
operation where switch ON=Stereo and switch OFF=Mono. For mono operation connect only the left channel or
white connector. DIP switch #2 is used to activate the SRS WOW HD processing including TruBass and loudspeaker
equalization.
The Level Attenuator is set full clockwise (no attenuation) by default when shipped from the factory. A flashing red
LED on this circuit board indicates input clipping. If this LED flashes turn the level attenuator down until the
flashing stops. Always remove the end cap and verify the level trim is set properly when setting up a system for
the first time.
