DESCRIPTION

The Architectural Acoustics Automix™ is a high quality automatic mixer with eight transformer balanced, mic/line inputs. Each mic/line preamp provides a gain control, phantom power (mic inputs), low cut filter, activity/clipping LED, and a choice between manual or automatic operation. Each channel can be muted externally or multiple channels can be muted externally via an assignable mutebus. In addition, channels one and two provide adjustable priority and a signal processor loop. The master section provides a gain trim control, three sweepable notch filters, a downward expander, a transformer balanced output, and a remote volume port.

The Automix has been designed so that multiple units can easily be linked together to form a single mixer with many more inputs

(16, 24, 32...). The Automix is supplied with a plexiglass security panel to prevent changes to the installer's settings. The

Automix is packaged as a stand-alone unit, but will also rack-mount into a standard 19" rack with optional rack-mount kit.

ENGINEERING SPECIFICA-

TIONS

The automatic microphone mixer shall have eight transformer balanced microphone/line inputs. Each channel shall have its own gain and level control, as well as switchable controls for manual/automatic operation, low-cut filter, phantom power, and mutebus. Each channel shall have external muting capability, activity/clipping LED and a status (logic) output.

Channels 1 and 2 shall have a signal processor loop and priority controls. The master section shall have its own level controls, as well as controls for the notch filter and the downward expander.

External muting, remote volume, and the linking of multiple units shall be accomplished through barrier strip connections on the back of the unit.

The mixer shall have a frequency response of 20 Hz to 20 kHz +1/-2 dB. It shall have an

EIN of -122 dBu and the total harmonic distortion shall be less than 0.1% at 1 kHz.

The maximum output level shall be +20 dBu

(High-Z load) or +16 dBm (600 ohm load).

The unit shall be packaged in a rugged metal chassis 17" wide by 3.5" high by 10.2" deep. The unit shall operate from 120 V AC,

60 Hz, domestic; and from 230 V AC,

50/60 Hz, export. The unit shall be a Peavey

Architectural Acoustics Division model
