The digital matrix mixer with audio processing shall incorporate microphone mixing, matrix mixing, and signal processing in a single rack space unit.

The matrix mixer shall have 12 inputs and outputs: four line level inputs, eight microphone/line selectable inputs, and 12 line level outputs. Each mic/line input shall have four selectable filters, which
include all-pass, high-pass, lowpass, and notch; automatic gain control; phantom power; and automatic microphone mixing capabilities. The unit shall have four internal and four global automatic
microphone mixers, each with fully adjustable parameters. The microphone mixer shall use PA adaptive, adaptive ambient, chairman override, first mic priority, last mic mode, number of open mics.

The matrix mixer shall have a 12x12 internal matrix mixer with attenuation at every cross point in .5dB steps. Any input can be routed to any output or multiple outputs. The matrix shall consist of 12 analog inputs/outputs, 12 digital inputs/outputs from the network bus, and eight inputs/outputs from the processing blocks.

Signal processing shall be provided by eight assignable processing blocks, each with 15 programmable filters, delay, and compression. The processing blocks shall include such filters as high pass, low pass, all pass, low shelving, high shelving, notch, parametric EQ, CD horn, Bessel crossover, Butterworth crossover, and Linkwitz-Riley crossover. Filter setup shall be real-time. The unit shall include a signal generator for pink noise, white noise, and tone sweep capabilities, and shall be assignable to any input on any linked unit. Signal delay is adjustable up to 500ms.

The matrix mixer shall have up to 32 presets. Multiple presets can be used simultaneously without interruptions or interference with other presets. The unit shall feature a macro recorder to create up to
255 macros for simple remote control management of the system.

The unit shall have a 12-channel bi-directional audio bus to pass audio, system control, and four channels of NOM for four sub-mixers to other units. The maximum distance between linked units shall
be 80 feet (24 meters). Up to eight units can be linked for up to 32 line inputs and 64 mic inputs.

System settings shall be saved in the unit, and shall include password protection.

The unit shall be set up and operated with intuitive software that allows complete configuration of the system. Additional control shall be handled via custom setup software, RS-232 protocol with
communication speeds up to 57,600 baud, RS-485 control panels, or contact closure.

The unit shall have the ability to meter a group of inputs or an entire signal flow. Meters shall be provided on inputs, processing, and outputs for echo return loss, echo return loss enhancement, and
gate parameters.

The unit shall have a frequency response of 20Hz to 20kHz and a signal to noise ratio of 80dB re 0dBu, A Weighted.

The unit shall have an internal power supply that automatically adjusts between 100-240VAC of power input. The unit shall comply with FCC, CSA, IC, CE, NOM, ACA, SABS, VCCI, and JATE
requirements.

The ClearOne PSR1212 is specified.
