START & STATUS

ÔOUT MIX FEED': When you want to feed the audio signals from this cardÕs output to feed the MIX

BUS. The ÔoutputÕ is Ôdown streamÕ of the VCA, PA, and all other audio processing, so it will
include these signals and processing in the audio data which is fed to the bus. You must also
turn on one, and only one of the ÔMIX BUSÕ switches. This configuration card is used when you
want to feed the audio from this card, along with the audio from any number of other cards,
to one other card in the system (the card which will listen to the mix bus must be configured
with the ÔMIX LISTENÕ configuration card and the same ÔMIX BUSÕ switch turned on as on this
card).

The ÔBUS FEEDÕ pot on the front panel of the DR- Repeater card you are configuring

controls how ÔhotÕ a signal is sent to the MIX BUS from this card. By adjusting the ÔBUS FEEDÕ pot
levels of all of the cards feeding this MIX BUS, the relative volumes of all of the signals feeding
this MIX BUS can be adjusted.
