ProMix 12 Installation and Operation Manual

OPERATION

mode, an external amplified speaker must be connected to the TB OUTPUT as

described in Section 2.9.) If the TALKBACK button (20) is pressed and held down,

the “normal” audio feeding the Booth output is overridden with audio from

Microphone 1 (the console operator’s Microphone). The booth announcer can

respond by pressing the remote TALKBACK button (connected per Figure 2; see

Section 2.2.1.) The console operator via the Talkback speaker will hear the

announcer’s Microphone. (One-way operation is possible without using the

Talkback speaker. The console operator can still speak to the announcer, however

the announcer cannot reply.)

4.8 MONO OUTPUT

The console includes a Mono output that provides a summed (L+R) signal of either

the Program or Audition bus. The MONO OUT: PGM/AUD button (21) determines

which bus is sent to the Mono output. If this button is up, the Program bus fed to

the Mono output; if it is down, the Audition bus is fed to the Mono output. The

Mono output is always at the same level at the Program and Audition bus outputs.

4.9 MIX-MINUS OUTPUT

The console’s Mix-Minus output is a monaural mix of all sources assigned to the

Audition bus, except for Line channel #4. This input should be used for the

“Receive” (caller) audio from a telephone hybrid. The Mix-Minus output is there-

fore the same as the Audition mix, minus the caller. This Mix-Minus signal is nor-

mally fed back into the hybrid’s “Send” input.

4.10 VU METERS

The ProMix 12 features accurate VU meters (23) to monitor the main bus output lev-

els. Using the VU METER can meter either the Program or Audition bus:

PGM/AUD button (22). If the button is up, the Program bus is metered; if it is

down, the Audition bus is metered. Mix levels should be adjusted so most peaks

read about 0VU. The meters are calibrated so that 0VU equals +4dBm on the main

bus outputs.
