Operating Manual - MX-406 Stereo Microphone/Line Mixer
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 moni-
tors or an extra loudspeaker zone.
4.8 Stereo Output Level
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 con-
nect to a stereo recording device.
4.9 Mono Output Level
This control 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.
4.10 Headphones Level
This control adjusts the level of the stereo signal
to the headphone jack. Headphones should have an im-
pedance of 600 ohms or greater, or signal distortion may
result.
4.11 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.
4.12 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
microphones. If there is a mix of both condenser and
dynamic microphones, the phantom power will not affect
the operation of the most dynamic mics.
