These faders correspond to the selector buttons above and control the relative volume of each input in the
master output as well as the master output level. They are called faders because they are used to decrease
(rather than increase) the signal levels to make a balanced and pleasing mix. When they are set at Unity, at
6, they pass the audio signal through at the same level it was at when it entered this bus. This is why level
setting at the Input Bus is so important.
These meters show the audio signal level at the Main output. The strength of any audio signal that is routed
to the output will be displayed here. As mentioned above, these meters play a vital part in correctly setting
the audio levels to avoid clipping or other distortion. You’ll notice that the LEDs are green up through the +0
dB level, turn yellow at +4 dB, and turn red at +10 dB. As you set the audio level for each input, make sure
that the signal peaks to +8 dB or very occasionally to +9 dB. Every time the signal goes to +12 dB, it will be
distorted.
Use the Headphone section to accurately monitor any of the sources (Microphones, Aux-2, Aux-1 (MSC),
“Video” (VCR) or “Master” output. Repeated presses of the Headphone button cycle through the monitoring
choices. In many cases, headphones may be a more useful and accurate choice than speakers for audio
monitoring. For example, in a noisy club or at a concert, you won’t be able to hear any additional sound
coming through speakers. Headphones will also more accurately reproduce the sound you wish to monitor at
a lower cost than speakers.
