Procedure

Scenario:

You have an analog output of a Q-SYS Core wired to a Bluetooth transmitter that is sending audio, via Bluetooth, to an in-room self powered speaker for in-room amplification. This room is being used for conferencing and there is active AEC processing being done in the design.

The AEC reference mix is *incomplete* and you will never get rid of the echo unless/until you:

• Take a parallel output of your last audio pin output path before the audio hits Mic/Line out from the Q-SYS Core and then:
• Wire it to a Delay block.
• Send the output of the Delay block to your AEC reference mix *in addition* to the already standing AEC reference material(s).
• Push this change to the Core and fine-tune audio delay until any residual echo is eliminated
• The reason this occurs is due to the inherent (and variable) latency of Bluetooth TX/RX.. This must be compensated for in your AEC reference/mix/processing.
