No audio playing out of mall audio system. May also affect some custom audio systems

Potential Symptoms

  • Audio doesn't play out of the audio system even though input lights light up on the front of the BSS BLU-100 or other BSS BLU DSP (digital signal processor)

Environment

  • Mall audio system and possibly some custom systems
  • BSS BLU-100 (or other BSS BLU processor)
  • Contrio Controller with buttons and volume knob, EC-8BV or EC-4BV

Cause

  • For Mall systems and some custom systems, the Contrio controller is programmed as a source selector with the volume knob being the master system volume.  The volume knob is also a button which can be tied to a system mute.  It is possible this button was pushed muting all audio output.

Resolution

  • Push the volume button so that it unmutes the main output and allows audio to pass through the system.
