Operating Manual - MX-406 Stereo Microphone/Line Mixer
capacity of the MX-406, the stereo line input can be used as
stacking inputs for supplementing the MX-406 with another
mixer, such as an Ashly LX-308 stereo line level mixer.
4.7AuxMasterOutput
This control adjust the level of the aux master ¼"
jack output, which gets it's signal from the six aux level
controls on the input channels. It is used for an effects unit
send, or can drive a power amplifier for monitors or an extra
loudspeaker zone.
4.8MainOutputs
These two controls determine the signal level to the
¼" jack left and right outputs. They are used to drive power
amplifiers for the main loudspeakers, or to connect to a stereo
recording device.
4.9Mono/PhonesOutput
Thinner concentric knob adjusts the level of the
summed mono output. It is completely independent of the main
left and right master controls. In other words, changes to either
left or right output level will not affect the mono output level.
The outer concentric knob adjusts the level of the
stereo signal to the headphone jack. Headphones should have
an impedance of 600 ohms or greater, or signal distortion may
result.
4.10OutputMeters
A pair of peak reading 10 segment LED meters are
used to indicate stereo output level in VU. 0 VU is equivalent
to +4 dBu (1.228Vrms).
Green LED's are used below 0 VU, yellow above
0 VU and two red LED's indicate clipping. The clip LED's
turn on 3dB below actual clipping, detecting excessive signal
level on any critical audio path within the master section. If
all outputs are turned down and there is still clipping, then one
or more inputs must be turned down.
4.11PhantomPowerLED
The phantom power switch is on the back panel.
When the switch is pressed in, the LED is lit and +48VDC
is applied to all six mic inputs for use with condenser mi-
crophones. If there is a mix of both condenser and dynamic
microphones, the phantom power will not affect the operation
of the most dynamic mics.
