Operator Manual – MX-406 Mixer

MX-406 Rear Panel

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.

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.

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.

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.

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.

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.

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.

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.

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

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.
