  If your Viola Systems Amplifier has no sound but the front panel LED is lit, several things could be the cause. First, ensure all signal wiring is correctly connected. Next, verify that all units feeding the amplifier are switched on. Also, check that the input selector and any other relevant switches are set appropriately. Make sure the signal source is actually playing, and that the pre-amplifier or signal source volume controls are set loud enough to hear.

  If your Viola Systems Amplifier keeps shutting down, disconnect the inputs to both channels and also the speaker cables. Then, try to switch the amplifier on. If it starts but then shuts down, there may be a fault with the signal source or a short circuit in the speaker cables or speaker. Switch the amplifier off and reconnect one channel from the signal source. Switch the amplifier on. Switch the amplifier off and reconnect the other channel from the signal source.
