General Description The MCX-106 is a compact self-powered mixer with a Microprocessor controlled stereo cassette deck, designed to allow recording a live demo tape, performing to pre-recorded program material, recording sound on sound with an external tape source, and simultaneously performing as a six-channel "powered" main sound system and a six- channel independent monitor mixer. The MCX-106 features: six input channels, a 300 watt power am plifier, 9-band graphic equalizer, automatic compres

Input Connections Generally speaking, there are two rules to follow when connecting equipment outputs to the inputs of other equipment. 1. Properly match the impedances of the outputs and inputs. 2. Connect low impedance outputs to high impedance inputs. It goes without saying that not only input and output impedance matching but also level matching should be taken into consideration. Each input channel of the MCX- 106 is provided with an input TRIM control, so the usable signal level range is v

How to get a good mix Before connecting other equipment to the Powered mixer, If the trim control is set as shown in the left figure, the check the impedance and level of both. If the impedances input level controls can be set to the same position. and levels do not match, mixing will be very difficult and the S/N ratio will also be adversely affected. The input level controls are used in general between 6 and 8. Each input channel of the MCX-106 is provided with a TRIM control. Thorough underst
