ProMix 12 Installation and Operation Manual
INSTALLATION
2.1.6 MAIN MIX BUS OUTPUTS
The console’s six main mixing bus outputs appear on male XLR connectors (5). All
outputs are electronically balanced; each will drive a 600-ohm load. The nominal
level is +4dBm. Connect as follows:
PIN 1: Ground
PIN 2: Hi
PIN 3: Lo
Note: To feed an unbalanced load, connect to Pins 1 & 2 only. DO NOT
SHORT PIN 3 TO GROUND!
It is not necessary to terminate any console outputs.
2.1.7 MONITOR OUTPUT
The console’s Monitor outputs (6) are via a T/R/S jack. These outputs are unbal-
anced, and will drive 600-ohm loads. (Termination is not necessary.) The nominal
level is –10dBm. Connect the mating TRS plug as follows:
TIP: Left Monitor output
RING: Right Monitor output
SLEEVE Ground
2.1.8 BOOTH OUTPUT
The console provides a secondary Booth monitor output (7) that can be used to drive
headphones worn by an announcer in an “announce booth”. This output, via T/R/S
jack, will drive headphones of 24 ohms or higher. (Termination is not necessary.)
The nominal output level is 0dBm. The mating TRS plus should be wired as fol-
lows:
TIP: Left Booth output
RING: Right Booth output
SLEEVE: Ground
2.1.9 CUE/TALKBACK OUTPUTS
The console provides outputs to drive external amplified speakers for monitoring the
Cue bus and Talkback circuit (8). Using the Cue output is optional, as the Cue bus
can be monitored via the Monitor system (with the CueMix function) as well as via
the Phones output. The Talkback output must be connected to an external (ampli-
fied) speaker if this feature is to be used. The Cue and Talkback outputs are unbal-
anced and will drive 600-ohm loads to a nominal level of –10dBm. (Termination is
not necessary.) Inexpensive “computer speakers” are ideal for use with the Cue and
Talkback outputs (audio quality unimportant). The mating T/R/S plug should be
wired as follows:
TIP: Cue output
RING: Talkback output
SLEEVE: Ground
