ProMix 12 Installation and Operation Manual
INSTALLATION
CONTROL INTERFACE
MIC 2 & 3 REMOTE CONTROL
The console provides for remote control of Mic 2 and Mic 3 via the Mic 2 & 3
Remote Control connector (9).
This 15-pin D connector should be wired according to Figure 2.
Note that “cough switches” for Microphones 2 & 3 can be installed for use by the con-
sole operator if these microphones will be used in the studio. If these cough switches
are not used, jumpers must be installed as shown between pins 9 & 10 and between
pins 13 & 15.
Microphones 2 & 3 will not operate if these jumpers are missing.
Cough switches can also be installed for remote use, as shown connected to the
remote Microphone ON switches. If the “cough switches” are not used, jumper
wires must be installed in their place.
LEDs can be used to show “Mic ON”; be sure to include the 1K resistor as shown.
(This value can be changed to set LED brightness.)
The Talkback function allows the booth announcer to talk directly to the console
operator (off-air) via the Talkback system.
The MUTE TALLY output on pin 4 provides a means of switching external equip-
ment when the monitor mutes. This circuit goes to +12v (HI) when the monitor is
muted. It can be used to operate “ON AIR” warning light controllers, etc.
LINE CHANNEL REMOTE CONTROL
The console provides 9 momentary SPST switches than can used for “remote start”
of line channel source equipment, e.g, CD players, tape decks, etc. Interface to these
switches is via Line Channel Remote Starts connector (10), a 25-pin D connector.
WARNING: The maximum voltage that can be applied to Remote Start switches is
24vdc @ 100ma or less. DO NOT EXCEED THIS RATING. NEVER CONNECT
THESE CIRCUITS TO A 110 VOLT AC LINE! Connect the mating 25-pin D con-
nector according to Figure 3.
POWER INPUT
Plug the console’s external power supply into the Power jack (11). Do not use any
power supply not supplied with the console. The power supply is a “universal input”
type, and can be used with any AC input voltage between 100 and 250 VAC, either
50Hz or 60Hz. No changes to the power supply are needed. The AC mains cord
must have a connector appropriate for the AC socket being used.
