Telephone hybrids
STEP 8- CONNECT A TELEPHONE HYBRID
1) CONSOLE PHONE INPUT- A telephone hybrid has an audio input and an audio output. The hybrid audio output is the callers voice and is connected to the
source input channel SEVEN on the console.
2) CONSOLE MIX MINUS OUTPUT
- The input to the hybrid is from the console MIX MINUS OUT connector on the back of the console. A mix minus bus is a special
audio mixing bus that contains all audio on the console program bus MINUS the callers voice. In this way the caller hears everything except himself. If he was not
“minused” from the mix, then the caller would feed back to himself. The mix minus output is balanced (+4dBu) located on a 1/8" TRS phone jack.
3) CONTROL LOGIC
- The ARC-8 has no phone logic to turn the hybrid on and off. This should be done manually from the hybrid’s front panel.
4) LEVELS
- The console PHONE IN and PHONE OUT connectors are set for +4dBu levels.
