Problem

Unit indicates it has power and is turned on (LED lights on, LCD display on) but no audio passes. 

Solution | Workaround

Verify the following: 

• The unit is turned on (Power LED and LCD display both come on). 
• The presence of an input signal (Signal LED indicator flashes). Use another loudspeaker to verify the signal, if necessary. 
• If unit does not turn on, refer to K.2 Loudspeaker Does Not Turn On document. 

After verifying power and input audio signals, does the problem remain?
