Operating Of A Telephone Hybrid Or Isdn Codec With The Mix4 - junger MIX4 Operation Manual

There is a combined function for using the MIX4 with a Telephone Hybrid or an ISDN Codec.
This mode is within the Setup software by choosing the HYBRID function. The drawing below shows a
sample configuration for MIX4 and a generic telephone hybrid :

The first step is to select a Mix4 GPI for signaling an incoming call.
The next step is to select a MIX4 Tally output that signal the hybrid to accept the incoming call.
On the Desktop-Unit page of the Setup software, a User Button function must be selected to permit direct
talking to the hybrid. In this case the local talkback source is used.
On the Main page, the bus to be used to feed the hybrid will be selected by selecting the HYBRID function
for that bus.
Finally the HYBRID function must be activated on the Sources page for the Channel Strip button where
HYBRID has been selected as the input.
When HYBRID is selected for the first time as a source for a Channel Strip, you need to decide via
<SOURCE> selection from which channel (L or R) the signal is taken and how the <BUS> assignment will
be so as to insure that this Strip is not routed to the bus that feeds the hybrid! Unpleasant feedback could
otherwise result!
