The mixer shall have an “open  buss“ architecture to allow easy linking of the output busses of multiple units.It shall be mounted into a standard 1 RU all steel chassis with extruded aluminium front panel.


It shall have four independent 3 pin female XLR balanced microphone inputs which shall be able to be switched to line inputs. These inputs shall combine down to a stereo output pair of balanced male 3 pin XLR connectors.

Each input shall have EQ controls on the front panel for Low,100Hz 15dBCut/Boost,Shelving; Mid,800Hz 15dB Cut/Boost,Bell,Broad Q; High 10KHz 15dB Cut/Boost,Shelving. There shall also be a true L & R constant level Pan control.
Each channel shall also have a balanced jack Direct output, which shall bypass the mixed outputs. This output shall be able to be used concurrently with the mixed outputs.

Switchable Phantom power shall be available on all the microphone inputs, to enable the use of condenser microphones and direct boxes.

There shall be 5 pin DIN “open buss” connectors on the rear panel of the unit.
The Input Gain shall be variable between 20dB-60dB on Mic/Line channels by a rear panel trim control, as well as a Mic/Line input switch.

The Channel Level shall be variable from infinity to +6dB Gain, and the Frequency Response shall be 20-20KHz ±1dB. THD shall be less than .005%, 100Hz to 10KHz.
The Master Outputs Signal to Noise ratio shall be -90dB unweighted.
The Direct output impedance shall be 150 Ohms, and the balanced Master Outputs impedance shall be 300 ohms.                      
Maximum Output Level shall be +20dB
AC power range shall be switchable 100 to 120V or 220 to 240V AC, and shall be connected to the unit via a standard three pin IEC connector, with built-in fuse and voltage change switch.
The unit shall be the ARX MIXX
