The 6978 Communications module has three communications ‘channels’. all with
similar facilities. All sections have microphone inputs with variable gain; phantom
power on/off; routing to ‘All’ Sub groups and individual routing switches for the Aux
Groups. Comms 3 is slightly different in that it has a front panel mounted mic input
connector and a Talkback switch.
Since all three sections are similar, only Comms 1 is described in detail.
