How do I inject program audio to a channel on my MS_704?
On the back panel of the MS-704, you plug program audiointo the program XLR input. Then remove thefront panel cover plate on the bottom-front of the MS-704 and select the channel (A, B, C or D)that you want the audio to be injected on to on the PROGRAM dip switches. Then you take your small screwdriver andadjust the amount of that audio you want on the channel on the pot associatedto that channel. When done, replace thecover and you’re done.
