Millennia Mixing Suite and Power Supply

Offering 100% bus compatibility with George Massenburg's (GML) HRT-9100 Mixing System, the Millennia MIXING SUITE provides audio excellence and modular flexibility. With an expanding selection of input and output options, the MIXING SUITE is intended for critical location recording, sub-mixing, large MIDI-array mixing, film and stage work, multi-source mastering, and more. Multiple Suites can be combined for a total of up to 80 input channels.

Mixing suite includes 5 microphone preamp modules (with EQ), 1 passive input module, 1 stereo input module, 1 aux send/return module and one master module (including metering, 2 headphone outputs and oscilator module.  

The mixing suite includes a talkback amplifier with its own mic input.

Employing circuitry similar to that found in the acclaimed Millennia microphone preamplifiers, the MIXING SUITE is almost entirely DC-coupled without the addition of servo amplifiers. Each circuit element has been carefully optimized in critical listening tests for musical realism, spatial accuracy, and dynamic stability. No detail of circuit design, mechanical topology, or component selection has been neglected.

The Millennia Media MIXING SUITE is a high speed, high headroom signal path design. Utilizing the finest French Vishay conductive plastic potentiometers and superior grade componentry throughout, the MIXING SUITE is designed for a lifetime of professional industrial applications. Millennia will continue to develop and release new plug-in modules. Currently planned modules include an ultra-transparent parametric EQ, A/D converter, etc.

A rugged, high-performance external power supply accompanies the MIXING SUITE. The power supply chassis employs a 40W engineer's talkback amplifier with a feature we call TRUE-MUTE. In many talkback systems, the amplifier remains on, with an audible hum or hiss. The TRUE-MUTE system assures that all power is off when talkback is not selected, yet returns quietly to full power in less than 200 mS when talkback is selected.
