2.2.14 MONITOR MUTE TALLY OUTPUT
SIXMIX provides two logic outputs to control On The Air tally lights: “MAIN” and “MIC 2”. Both outputs are via the
1/8” MIC TALLY jack. These outputs should be connected to a Henry Engineering Superely for tally light control.
Warning! DO NOT connect high voltage AC tally light wiring directly to the console!
The Main Tally output will turn on tally lights whenever either Mic 1 or Mic 2 is ON, if the Mic channel(s) has been
programmed for Monitor MUTE (See Section 2.1.1). The Main Tally output provides +12VDC whenever either
Mic 1 or Mic 2 is ON. Connect the 1/8” TRS plug as follows:
TIP:
Connect to Superelay “+ IN” terminal
SLEEVE: Connect to Superelay “G” terminal
The Mic 2 Tally output will be active whenever Mic 2 is ON, whether or not the Mic 2 Monitor Mute is set ON.
This output provides a Ground (logic-low) whenever Mic 2 is on. Connect the 1/8” TRS plug as follows:
RING:
Connect to Superelay “ON” terminal
SLEEVE: Connect to Superelay “G” terminal.
Also, be sure to connect a jumper wire between the “OFF” and “G” terminals of the Superelay.
Both Tally outputs can be used simultaneously to operate two Superelay units.
2.3 GROUNDING
For best performance, especially in high RF fields, connect the chassis GND screw to the station ground.
The ground terminals of all balanced input connectors (Mics, Lines 3A-5A, Air) are connected to the chassis, which
is connected to the AC power cable ground pin. Note that the ground terminals of unbalanced line inputs (3B-6B)
and all audio outputs are connected to the internal “audio ground”. There is DC isolation between the internal audio
ground and the chassis ground.
2.4 POWER
INPUT
SIXMIX is powered with an internal power supply. It is set at the factory for use with 115 volt AC mains.
To use SIXMIX with 230 volt AC mains, have a qualified technician remove the jumpers between E16+E18, and
between E17+E19. Then install one jumper between E16+E17. Change the fuse to .125A.

ADJUSTMENTS AND SETUP
3.1
MIC GAIN ADJUSTMENT
Each of the 2 Mic input channels has a GAIN adjustment to optimize the mic preamp gain for the microphone being
used. The gain can be varied over a 25dB range. Use a small screwdriver to carefully adjust the gain trimmers,
located on the top panel, just below the Cough buttons. To quickly set mic gain, follow these steps:
1.
Assign the Mic channel to the Program bus.
2. Set the Mic channel fader to –15db.
3. Speak into the microphone; set gain so that voice peaks read about 0VU on the console VU meters.
4.0 OPERATION
Operation of the SIXMIX is simple and straightforward. The mix bus buttons are color-coded: RED = PROGRAM,
BLUE = CUE. Color-coded LEDs match the button colors, and visually indicate switch positions for efficient, error-
free operation. If the LED is red, the channel is “on the air”; if it’s blue, the channel is in Cue mode.
Audio sources are mixed to the Program bus. Mix levels are monitored using the LED VU meters. Channels 2 thru
6 can be also be fed to the Cue bus and Cue speaker. The console’s Program output, an Air monitor, or PC play-
audio can be monitored via the Monitor and Headphone systems. A second announcer can use a Guest Pod for
monitoring. The console operator can talk to the booth announcer using the Talkback facility; the booth announcer
can respond via the Cue system. The AutoCue system provides for easy and efficient source cueing.
