Audio mixer
These CH1~CH4 Audio Level Faders are for controlling the CH1~CH4 audio
mix.
These faders correspond to the Audio Source selector buttons 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 create a balanced and pleasing
mix. When the CH1~CH4 Audio Level Faders are set at -6dB, or Unity, they
pass the audio signal through at the same level as when it entered the bus.
This is why the level setting at the Input Bus is so important.
MASTER
: This Slider is for controlling the audio level for the Mixed audio
output.
Audio Input Source Selectors and Level Controls
This section of the SE-2000 controls which audio input channel (CH1~CH4)
will be sent to the Audio Bus and its associated Fader.
This row of audio channel selection buttons has LEDs built in to show which
input channel is active. Level control for each audio input source is via the
rotary pots above each of the audio channel selection buttons.
A+V:
When this button is engaged or lit, the audio associated with a selected
video input source automatically follows the video through any transition
between the Main and Sub Sources. When the A+V button is inactive, the
audio sources must be switched manually. For more information, see
A+V

Audio LED Meters
These meters play a vital part in correctly setting the audio levels to avoid
clipping or other distortion.
The LED style Audio meters, show the signal strength at the Audio Output.
The signal they measure is determined by the sources selected by the Audio
Bus selectors and the levels set by the rotary pots and faders.
Audio Monitor Button
Use the Headphone section to monitor any of the sources (CH1, CH 2, CH3,
CH4) or “Master” output. Repeated presses of the Headphone Audio Monitor
button will cycle through the monitoring choices. In many cases, headphones
may be a more useful and accurate choice than speakers for audio
monitoring.
