Input Pad -The input pad is a 20dB output fader recording off of the stereo mix, or attenuation switch on the rear panel for use for stacking the MX-406 with another mixer. with the XLR microphone inputs. It should 7. Aux Master Output -The 1/4" jack aux master normally be left in the "out" position for best output is used to drive a monitor or zone signal to noise ratio and should only be used amplifier, effects processor or recording device. when the input is being overdriven with the gain It is pseudo-balanced, which means that while control at its minimum setting. it is a single ended signal, it has balanced 3. Line Input -The line input is a standard 1/4" impedance for low noise. TRS active balanced type. The line input 8. Mono Output -The XLR mono output balanced impedance is 20... It will combines the left and right stereo signals (pre accommodate a wide range of input levels. output fader), and uses an isolation transformer 4. Channel TRS Insert -A channel TRS insert capable of driving 600 ohm lines. This signal is patch point allows a device such as a remote determined by the mono output level control, level controller, graphic equalizer, noise gate, with a nominal operating level of +4dBu. compressor/limiter, or direct out recording Note: The transformer-balanced outputs are device to be used with one or more input designed to drive up to +24dBu into 600 channels. The MX-406 TRS insert jacks use loads. With output transformers, the level the tip for output and ring for the returning increases as the impedance of the terminating input. These signals are unbalanced. To use load exceeds 600 ... Unlike a direct-coupled the TRS insert as a Direct Line Output (pre EQ) output, transformers are affected by termination for recording, you must make a special cable impedance. Expect a slight increase in output with tip and ring connected at the MX-406 end level when driving high impedance inputs with and a tip-sleeve mono plug at the other end. these outputs. The output meters will remain Connecting tip and ring at the mixer insert jack accurately calibrated to the levels present on is necessary for uninterrupted signal within the the transformerless outputs, regardless of the mixer when using direct line outputs. load on the transformer outputs 5. Stereo Line Input -The stereo line RCA inputs 9. Stereo Outputs -The 1/4" jack stereo right and have a nominal operating level of -10dBu to left outputs are controlled by the left and right match most consumer audio sources. This master. They are balanced TRS jacks with a signal is controlled by the Stereo Line Input dial nominal operating level of +4dBu into any load, on the front panel. This input is also used as a and are capable of driving long lines. stereo effects return, or as a stacking input for 10. +48V Phantom Power Switch -This switch adding additional mixers. applies +48VDC to all six XLR mic inputs to power condenser microphones. Installation Always switch the unit off before making substantial changes to the settings or connectors. Use four screws and washers when rack mounting. This unit has specific electrical and signal requirements, please take special care to double check all connections and settings and refer to the specifications section of this manual. The unit should be connected to a standard 3-wire grounded electrical outlet supplying 100-240 Volts, 50-60 Hz. To reduce the risk of ground loop hum, connect all audio equipment to the same electrical power source. Removal of the ground pin is both unlawful and dangerous, as a potential shock hazard could result. Overall power consumption is less than 30 watts.

Four of the input channels are used for vocal microphones, while the remaining two channels are used for stereo accompaniment tracks. The stereo line input is used for additional pre-recorded music such as that of a movie soundtrack or CD player. Stereo line output RCA jacks are used to record the event to a cassette, video camera, or even a PC with recording capabilities. Stage monitors are fed ...
