Setting the Channel Level
The Channel Level control is a vertical slider that is adjusted in 1-dB increments and con-
trols the output level for the channel. The Channel Levels can range from -60 to 12 dB. If
yo
u place the mouse over the slider, the numerical value of the level appears.
Signal LEDs, Clip LED, and VU Meters
Each input channel has one or more input signal LEDs, Clip LED, and two vertical volume
unit (VU) meters, labeled “IN” and “OUT”.
The green input signal LEDs automatically illuminate when a signal is being received. The
re
d Clip LED automatically illuminates when the signal is clipping (i.e., exceeding a pre-
defined threshold). Clipping can result in distortion and, for output signals, can even
d
a
mage speakers. Note that the specific level and duration that a signal must reach in
order to trigger the input signal LED can be configured via the
Signal Present settings.
The “IN” VU meter indicates the strength of the channel’s input signal (after gain adjust-
ments), while the “OUT” VU meter indicates the strength of the channel’s output signal.
Th
e VU meter not only illuminates green, yellow, or red (depending on the signal level),
but also has a scale ranging from -60 to 0 dB to indicate the actual signal level.
Muting a Channel
You can mute a channel to cut off an audio signal and stop the input signal from being
sent to the output channel. Note the input signal will still be visible on the IN meter, but
the OUT meter will show that nothing is being forwarded to the output channel.
To mute a channel:
1 On the appliance Web UI’s main page, select DSP.
2 Click the Mute button for the channel that you want to silence.
Status Provides real-time status for the amplifier, including which
mo
de (2-channel or single channel bridge mode) the out-
put is configured, channel output limits, and more.
Reset button Present on almost all DSP screens other than the main
mi
xer, this button will reset the DSP settings to the dis-
played feature’s default setting.
