Cloud rackmounting mixers have been designed as a solution for systems integrators whereby a product is required to be compact yet allow a number of sources to be combined into a single audio output.
A 7-input, 1U rackmountable mixer that allows the user to combine various line, microphone, and auxiliary audio sources and output via single balanced stereo output. Five primary input channels, each of which has balanced microphone input and unbalanced stereo audio input via RCA phono connections, are joined by an independent microphone channel that uses ‘VOX’ detection to allow paging use with voice-over-programme ducking. An emergency input via balanced phoenix style connector automatically mutes all other channels to conform to PA/VA regulations. An internal jumper determines whether the microphone channel should remain unmuted for announcements.
The front facing panel of the MX155 mixer features all output volume control via independent channel rotary controllers, HF (+/-10dB at 10kHz) and LF (+/-10dB at 50Hz, CH1-5; +/-10dB at 100Hz, Mic channel) EQ controllers on each input channel, and a ducking mix control. A master output rotary controller is positioned to the right of the panel with a 10-stage LED VU. A 6.3mm jack headphone socket and volume controller allows monitoring directly from the front panel, whilst a latching on/off switch and LED give easy access to powering. A 3.5mm TRS jack auxiliary audio input, with corresponding level controller, is positioned to the left of the panel. The rear facing panel of the mixer hosts all other I/O connections and input gain controls.
