General troubleshooting for when "no audio" is reported for an IZA 2120-HZ or LZ amplifier. 

 

Relevant Product(s)

  • FreeSpace IZA 2120-HZ
  • FreeSpace IZA 2120-LZ

 

Possible Resolutions

  • Check input wiring and input signal LED to ensure proper signal is being received. 
  • Check to be sure the proper speaker EQ is selected. Particularly if using an IZA 2120 with the "FS3B" EQ option. This will be low frequency only, and may not be heard on mid-high frequency BMS speakers. 
  • If using a ControlCenter CC-1 or CC-2 controller, be sure this is wired properly. If a CC-2 is being used, be to wire for both primary functions.
  • If the A/B terminal is not wired, it will default to input B only when only one controller is connected.
