1.5.2 Mic Use
Mic channels should always be activated with the slider down, and then “potted up” to avoid a sudden “room rush” of
background sound.
Cue speaker muting is only provided when a mixing channel is turned “on”. Therefore, feedback can occur between
the cue speaker or the monitor speakers (if cue monitoring is selected) and a mic input if the mic channel is placed
in cue. To avoid this possibility, install the cue inhibit jumpers on the section of the Six Channel Control Board associ-
ated with the mic channel. This will prevent a mic channel from entering the cue mode and possibly cuing feedback.
Consult the Six Channel Control Board Section for details on programming information.
1.5.3 Cue Circuitry
Unless disallowed by jumper removal, all selected inputs maybe placed on the cue bus by depressing the cue button,
located above the fader. Refer to Section 2.2 for additional information.
The cue signal is monitored by the cue speaker, and level adjusted by the front panel cue level control. The cue
speaker is muted by any input that is turned “on” and that was pre-selected during installation to activate the Mute 1
control bus. The internal cue speaker may be disconnected and a remote speaker connected in its place. Consult the
Output Board Section for detailed information on wiring.
In addition, the cue signal maybe selected for monitoring by the headphone or monitor amplifier select switches.
1.5.4 Output Routing
Each mixing channel can be routed to any combination of PROGRAM.1, PROGRAM.2, and PROGRAM.3 mix buses.
All buses provide identical stereo performance allowing them to be used as a back up to the airchain, as a separate
program bus, or to preview or record material. Note that PROGRAM.3 features an additional analog mixed mono out-
put.
1.5.5 Utility Buses
Millenium digital consoles feature 10 fully programmable utility buses. Via software programming every input may be
routed to any mix minus bus on a pre or post fader, or pre or post on-off switch basis.
Applications for the Utility buses include traditional “mix minus” uses, fold-back monitoring special monitor sends and
intercom functions.
Mix minus configurations can ONLY be changed via the Millenium PC software link. Consult the software section for
connection, programming and configuration options.
Note that UTILITY buses 1 & 6 are genrally utilized for PROGRAM.3
1.5.6 Mix-Minus via the PROGRAM.3 (formerly the “TEL” Bus)
Talk show hybrid telephone patches frequently require a return feed to the caller that does not contain his own voice
(mix minus). To accomplish this, the host may be routed to PROGRAM.1 and PROGRAM.3 and the caller to PRO-
GRAM.1 only. The PROGRAM.3 bus should then be fed back to the telephone hybrid and Program audio used to feed
the air chain. To prevent feedback in this application, the studio monitor speakers should not be used.
A “fold back” feed can also be created by feeding all microphone inputs into the PROGRAM.1 mix bus, and feeding
all other inputs to both PROGRAM.1 and PROGRAM.2 mix buses. Switch the monitor speakers to PROGRAM.2 and
feed the air chain with program signal. In this application, the mic inputs need not mute the monitor speakers, as no
feedback will result.
1.5.7 Monitor Amplifier Output Select
The monitor input select switches on the right-hand side of the console allow monitoring of the PROGRAM buses, cue
and four external stereo inputs which are common to the monitor and headphone circuitry. All monitor outputs follow
these switches. Level adjustment for the control room monitor output is provided on the front panel. In addition, the
control room monitor output is dimmed to a level that has been preset by a trimmer on the Output Board by the Mute 1
control bus. A studio monitor output that is muted by the Mute 2 bus, and an unmuted monitor output are also provid-
ed. In addition, a prefader, unmuted monitor output is available.
