MX-406 Rear Panel

1.Microphone Input - The MX-406 microphone input is an active balanced type with a nominal impedance of 1200 ohms. Performance is best with a 200 ohm microphone.

2.Input Pad - The input pad is a 20dB attenuation switch on the rear panel for use with the XLR microphone inputs. It should normally be left in the "out" position for best signal to noise ratio and should only be used when the input is being overdriven with the gain control at its minimum setting.

3.Line Input - The line input is a standard 1/4" TRS active balanced type. The line input balanced impedance is 20
. It will accommodate a wide range of input levels.

4.Channel TRS Insert - A channel TRS insert patch point allows a device such as a remote level controller, graphic equalizer, noise gate, compressor/limiter, or direct out recording device to be used with one or more input channels. The MX-406 TRS insert jacks use the tip for output and ring for the returning input. These signals are unbalanced. To use the TRS insert as a Direct Line Output (pre EQ) for recording, you must make a special cable with tip and ring connected at the MX-406 end and a tip-sleeve mono plug at the other end. Connecting tip and ring at the mixer insert jack is necessary for uninterrupted signal within the mixer when using direct line outputs.

5.Stereo Line Input - The stereo line RCA inputs have a nominal operating level of -10dBu to match most consumer audio sources. This signal is controlled by the Stereo Line Input dial on the front panel. This input is also used as a stereo effects return, or as a stacking input for adding additional mixers.

6.Stereo Line Out - The stereo line outputs are nominal -10dBu "premaster", and are not affected by the main Left/Right output controls. These outputs would be used for making a pre- output fader recording off of the stereo mix, or for stacking the MX-406 with another mixer.

7.Aux Master Output - The 1/4" jack aux master output is used to drive a monitor or zone amplifier, effects processor or recording device. It is pseudo-balanced, which means that while it is a single ended signal, it has balanced impedance for low noise.

8.Mono Output - The XLR mono output combines the left and right stereo signals (pre output fader), and uses an isolation transformer capable of driving 600 ohm lines. This signal is determined by the mono output level control, with a nominal operating level of +4dBu.

Note: The transformer-balanced outputs are designed to drive up to +24dBu into 600
loads. With output transformers, the level increases as the impedance of the terminating load exceeds 600
. Unlike a direct-coupled output, transformers are affected by termination impedance. Expect a slight increase in output level when driving high impedance inputs with these outputs. The output meters will remain accurately calibrated to the levels present on the transformerless outputs, regardless of the load on the transformer outputs

9.Stereo Outputs - The 1/4" jack stereo right and left outputs are controlled by the left and right master. They are balanced TRS jacks with a nominal operating level of +4dBu into any load, and are capable of driving long lines.

10.+48V Phantom Power Switch - This switch 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.
