manual abstract
With 5 outputs, 4 mixing busses and 8/12 input channels, the M508/512 makes an excellent main mixing board for small to medium scale nightclub, theatrical and broadcast jobs. In large scale concert reinforcement environments, the M508/512 can be used as an adjunct to the main mixing console or as a stage monitor mixer. The M508/512 is built of only the finest components such as smooth, quiet conductive plastic faders, and equalizers with “flat”position detents. These controls are calibrated accurately, in dB, for precise, repeatable settings that save valuable set-up time. To ensure the M508/512 holds up under real world" conditions, it is equipped with a bipolar 25 V power supply that affords a generous margin of headroom (an easy +24 dB output). Internally the M508/512 has the convenience of modular plug-in circuitry, and outside a solid front panel adds to strength and durability. You’ll appreciate the extra refinements in the M508/ 512’s advanced technology, reliability and human engineering. To take full advantage of your M508/512 mixer, please read this manual carefully.

(0 VU = +4dB). 1 LED built into each input channel and each VU meter. Input LEDs turn on when post-input selector signal reaches or exceeds 3dB below clipping. Meter LEDs turn on when output signal reaches or exceeds 10dB below clipping. For remote powering of condenser microphones, DC can be switched on via a rear panel phantom power switch. (+40V DC for US & Canadian models and +48V DC for the other model) Voltage is applied to pins 2 and 3 of the input XLR connectors via a pair of 6.8kft resistors that feed each balanced input transformer.
