ProMix-1 Installation and Operation Manual
OPERATION
OPERATION
Operation of the ProMix-1 is simple and straightforward. Microphone and USB
audio are mixed to the Program output. The operator can use headphones, plugged
into the front panel ¼” headphone jack to monitor the Program audio as well as
IFB/Cue (Return)audio fed into the IFB Input.
PROGRAM AUDIO CONTROLS
The Program audio can be turned on and off using the front panel PGM
(Local)On/Off button (1). When ON, the “PGM” LED (2) will be illuminated. The
output level is determined by the rotary PGM (Local)Level control (3). The “nor-
mal” position is at three o’clock position, which yields 6dB of “in hand” gain when
the rotary PGM (Local)pot is turn fully clockwise.
HEADPHONE (HdPh) OUTPUT CONTROLS
The user can monitor the PROGRAM output and IFB/Cue (Return)audio via the
jack on the front panel (4). Headphones with impedances of 32 ohms or higher can
be used. Do not use 8-ohm headphones. The headphone output is equipped with
Program and IFB pan pots, (5) which determine what is heard through the head-
phones. The PGM (Local)pan pot adjusts if the program audio is fed to either the
left, right or both ears. The same holds true for the IFB pan pot, which adjusts if
the IFB audio is fed to either the left, right or both ears. The headphone volume
is adjusted with the HdPh # control (6).
TALKBACK FUNCTION
The ProMix-1 includes talkback capability that permits the ProMix-1 and/or
ProMix-4 users to speak to an announcer who is wearing headphones connected to
either a ProMix-1 or ProMix-4 via the optional ProMix HUB-6. When the TALK-
BACK button (7) is pressed the TB LED (8) will light and the “normal” audio being
fed to the Program output is interrupted and is overridden by audio from the
Talkback circuit. All assigned channels are fed to the “Talkback” buss attached to
the ProMix HUB-6. When the talkback push button is pressed, a short burst tone is
injected into each headphone, notifying the connected users that one of the attached
ProMix’s would like to talk. To use the talkback system, simply press and hold the
“Talkback” push button for as long as you want to communicate. All partiers want-
ing to talk, simply presses and holds the talkback button.
The short tone burst is generated each time the talkback button is pressed. The tone
level can be adjusted on the Hub.
PROGRAM LIMITER
The ProMix-1 is equipped with a soft program limiter, the “Limit” LED (9) will
light when the program audio is in a clipped condition.
