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, Audition, and Tel (mono) mix buses. The program

and audition buses provide identical stereo performance allowing the audition output to be used as a back up to the

program bus, as a separate program bus, or to preview or record material.

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.

1.5.6 Mix-Minus via 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 and TEL and the caller to Program only. The TEL

bus should then be fed back to the telephone hybrid and Program audio used to feed the air chain. To prevent feed-

back 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 mix bus, and feeding all

other inputs to both program and audition mix buses. Switch the monitor speakers to audition 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 Amplier Output Select

The monitor input select switches on the right-hand side of the console allow monitoring of program, audition, tel, 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.
