PHONE MODULE NOTE:

The logic controls (1) Stop Logic,

(2) Start Logic, and (3) Logic com-

mon are momentary closures from

a dry contact reed relay (max cur-

rent = 50 milliamps). They are avail-

able on the ‘Phone module in’ and

‘Logic’ connectors for connection to

the hybrid.

Stop Logic

a) 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 input on the phone module.

b) CONSOLE MIX MINUS OUTPUT

- The input to the hybrid is from the console PHONE OUT connector on the

back of the module. A mix minus bus is a special audio mixing bus that contains all audio on the console 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.

c) CONTROL LOGIC

- The hybrid has two ways to “answer” the caller and pick up the telephone line: front

panel manual control of the hybrid itself and remote control. For manual control, an On and Off button will be

located on the front panel of the hybrid. For remote control, the PHONE LOGIC module connector (RJ45)

must have a custom cable connecting it to the console source start/stop logic. The logic is dry reed relay

closures for both Start and Stop as shown below.

d) CALIBRATION

- The console PHONE IN and PHONE OUT connectors are set for +4dBu levels. These connec-

tors have trim pots on the top of the module
