6.2 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 mini-

mum setting.

6.3 Line Input

The line input is a standard 1/4" TRS active bal-

anced type found in the same "combo jack" connector as

the mic input. The line input balanced impedance is

20KΩ. It will accommodate a wide range of input levels.

6.4 Channel TRS Insert

A channel TRS insert patch point allows a de-

vice 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 out-

put and ring for the returning input. These signals will

be unbalanced, so cable length should be at a minimum

to maintain low noise.

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.

6.5 Stereo Line Input

The stereo line RCA inputs have a nominal oper-

ating level of -10dBu to match most consumer audio

sources. This signal is controlled by the Stereo Line In-

put dial on the front panel. This input is also used as a

stereo effects return, or as a stacking input for adding

additional mixers.

6.6 Stereo Line Out

The stereo line outputs are nominal -10dBu "pre-

master", so they are not affected by the settings of 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 stereo output into

another mixer.

6.7 Aux Master Output

The 1/4" jack aux master output is used to drive

a monitor or zone amplifier, effects processor, recording

device, or any function which requires level control inde-

pendent from the main stereo mix. It is pseudo-balanced,

which means that while it is a single ended signal, it has

balanced impedance for low noise when driving an active

balanced input circuit over a long distance.

6.8 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. Pin 1 is
