Sum Mono Switches - Separate switch for Channel "A" and Channel "B"
These switches combine the content of the Left and Right line inputs into summed mono input signal. There
are sometimes situations where a sound system is operated in a non-standard format where a stereo source
signal may bot be desired. Inclusion of a sum switch expands the versatility of these input channels, including
where the input is a mono signal source.
Channel ON Switch (Illuminated when ON)
When activated, routes the stereo input channels signal to the master output by way of the Left-Right / Center
Assignment switch. The Solo PFL switch and Signal Present/Peak LED will remain active regardless of the
position of this switch.
Stereo Line Input Channel Level
This high quality rotary control adjusts the channels stereo level that is being feed to the master output section
of the mixer.
Peak/Signal Present LED Level Monitor
Dual-color LED monitors the combined (left + right) channel levels. In normal operation, varying intensity of
the green LED represents acceptable signal levels. Should levels approach clipping, the LED will illuminate red.
This should be an indication to the operator that the channel input level control should be decreased until the
red peak indicators are no longer activated. (Overall output levels can be adjusted by raising the master output
level position to offset any decrease in level caused by lowering the input channel faders).
Left-Right / Center Assignment Switch (Illuminated when assigned to Center)
Assigns stereo input sign to L-R Mix bus (Default) through the Balance Control or when switch is depressed, to
the Center Mix Bus as a Summed Mono signal. This assignment method prevents the signal from being
accidently fed to all mix buses when employed in a typical LCR Installation where Left-Right speaker are used
for music reproduction and the center is used for vocal reproduction.
