[. . . ] Microphone Input 1 can be switched to line level, set to have priority over all inputs, and can be activated by either VOX with an adjustable threshold or a contact closure. Activation of any microphone override provides 18Vdc (300mA) at a barrier connector on the rear panel, which may be used to drive LEDs or relays. Two unbalanced, stereo Aux inputs are internally summed to mono and selected by a switch on the front panel.

Integrated Mixer/Amplifier
Architects' and Engineers' Specifications
The integrated mixer/amplifier shall have a nominal output power of at least 160W RMS. It shall operate on 115VAC or 230VAC at either 50Hz or 60Hz and have its source power supplied by a detachable IEC power cord. In addition the unit shall be capable of being directly powered by a 24Vdc source, such as storage batteries. The unit shall have a constantimpedance output to drive a 4 load at its rated output. It shall also have 25V, 50V, 70V and 100V constant-voltage outputs with like performance. Inputs to the unit shall include: at least four actively balanced microphone; two unbalanced, stereo Aux; and an unbalanced signal processing return. Outputs shall include: at least two unbalanced Tape (auxiliary) with a common, continuously variable level control; and one signal processing send. Balanced connections shall be made through XLR connectors and unbalanced connections through RCA connectors. Microphone Input 1 shall have adjustable sensitivity between mic and line, selected by a switch on the rear panel. This input shall also be programmable to completely exclude or attenuate all other inputs when its priority link is activated by either a contact closure or a VOX circuit, with a continuously adjustable threshold. The XLR connector for Input 1 shall be wired, in parallel, to a barrier strip on the rear panel. [. . . ] LED status indicators shall be provided on the front panel to indicate power, signal present at the output terminals, peak signals near clipping and an overload condition. The integrated mixer/amplifier shall be a model AM4160, manufactured by Mackie Industrial.
