Operating Manual -MX-406 Stereo Microphone/Line Mixer
(Mono Output, cont.)
Note: The mono transformer-balanced output is designed to drive up to +24dBu into 600 ohm loads. Because of the
nature of an output transformer, the output level increases as the impedance of the terminating load becomes higher than 600
ohms. Whereas a "direct-coupled" output stage like that of the right and left outputs will not change as the load changes, any
transformer used in an audio path is affected by its termination impedance. Since line level inputs on audio devices are typi-
cally 10KΩ or higher, expect a slight increase (2.5dB) in output level when driving conventional active 10KΩ inputs with the
transformer outputs.
6.9 Stereo Outputs
The 1/4" jack stereo right and left outputs are controlled by the left and right master . They are pseudo-balanced TRS
jacks with a nominal operating level of +4dBu into any load, and are capable of driving long lines .
6.10 +48V Phantom Power Switch
This switch applies +48VDC to all six XLR mic inputs to power condenser microphones . Phantom power will not
affect most dynamic mics, which may be used along with condenser mics .
7. TYPICAL
APPLICATIONS:
7.1 Small Sound Reinforcement System:
In the setup shown here, the MX-406 is used
to mix typical sound sources that might be
found in a church, small club, school theater
or similar environment . Four of the input
channels are used for vocal microphones,
while the remaining two channels are used
for stereo accompaniment tracks . The stereo
line input is used for additional pre-recorded
music such as that of a movie soundtrack, CD
player, or MP3 player . Stereo line output
RCA jacks are used to record the event to
a cassette, video camera, or even a PC with
recording capabilities .
Stage monitors are fed using the aux mix
to the master aux output, and left and right
outputs drive the main speakers . The mono
output drives a 70 Volt distributed sound
system amplifier, used for plenum (ceiling)
speaker installations .
