All three models in the series have stereo program outputs, and differ only in the number of input channels: the MQ802 has 8, the MQ1202 has 12, and the MQ1602 has 16 input channels. Each channel has a pair of switch-selectable inputs, one XLR-type connector and one phone jack, either of which is usable with mic or line level sources. There are 4 mixing busses: program left and right, echo, and foldback. The program outputs are both equipped with 9-band graphic equalizers, useful for increasing the available sound system gain before feedback, and for making overall tonal adjustments to the program. MQ-Series mixers are ideal for use in cabarets or nightclubs, as well as for concerts, school productions, trade shows, and small theatrical productions. Because the mixing busses all have sub-inputs, two or more mixers can be linked to obtain more input channels and sub-group capability. The mixers are designed for easy interface with other equipment. Each channel input has both a low impedance XLR-type connector and a high impedance phone jack, each of which is switchable for nominal levels from —60 to +4dB (OdB ref. 0.775V rms). The program outputs are brought to both balanced XLR-type connectors and unbalanced phone jacks, with +18dB maximum level. And the echo/effects output is brought to two phone jacks, providing a choice of +4dB and -20dB nominal levels. Auxiliary inputs are able to accept nominal levels from -32dB to +4dB. Thanks to this added flexibility built into the mixers, external pads and transformers are seldom required. Other features include dB-calibrated faders, bar graph style peak-indicating meters on the outputs, and peak LEDs on the inputs. Each input channel also has 4-band equalization. Internally the mixers offer the convenience of modular plug-in circuitry, and outside a solid front panel adds to strength and durability. To take full advantage of your MQ-Series mixer, please read this manual carefully.
