APX 4500 05 control head audio options

[bboston]

I have a David Clark headset attached to an APX-4500 with and 05 control head. The audio is coming through the front speaker on the control head and in the headset. I cannot find an audio option in the CPS to disable the speaker. Am I missing the speaker disable option somewhere?

The O5 doesn’t have a speaker. Are you talking about the O2?

Have you looked in the audio profile that you’re using?

Assuming you mean O2, you have to open the control head and unplug the speaker.

My apologies, it's an O3 head

I'll get it right eventually. Yes it is the O2 control head
