Resolution

1. If there is no sound from the satellites, but the bass module is working
   1. Confirm that the amplifier or digital signal processor does not contain a low pass filter causing the system to output 'sub only' frequencies.
   2. If you are sending full range audio to the bass module, but there is no sound from the satellites, check the wiring from the bass modules to the satellites.
2.  If there is no sound from any of the loudspeakers, check the wiring and mode of the loudspeaker
   1. If you are using a 70V/100V amp, be sure the wiring is set properly for High-Z operation.
   2. If you are using a Low Impedance amplifier, check that the bass module is wired properly for Low-Z, 4ohm mode.

 

Wiring

70V/100V Bass Module Wiring

Transformer Settings

The transformer tap is set at the factory for 200W use. To set it for lower wattage, remove the end of the + jumper wire that is connected to 200W and reattach it to the appropriate tap (100W, 50W, or 25W).

Mono Direct - Input Wiring

To bypass the transformer and prepare the loudspeaker for 4W use and mono sound input, remove the two jumpers from the transformer settings on the front of the loudspeakers. Leave the CH1 and CH2 input jumpers on the back of the loudspeaker as they are.

Stereo Direct - Input Wiring

To bypass the transformer and prepare the loudspeaker for 4W use and stereo sound input, remove all jumper wires.
