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.
The
Mute
button will illuminate red. You can click the
Mute
button again to unmute
the channel.
Adjusting Volume Levels
The vertical slider control can be used to adjust the channel’s output level in 1 dB incre
-
ments between -60 dB and +12 dB. The overall adjusted output level of the channel
signal can be viewed on the “OUT” VU meter, marked in 2 dB increments between -60 dB
and 0 db.
To adjust the channel volume level:
1
On the appliance Web UI’s main page, select
DSP
.
2
Use the channel’s slider to adjust the volume level.
Selecting Input Type, Input Gain, and Phantom Power
Just above the labels for the input channels is a switch that allows you to select either
Line
or
Mic
as the input, indicating the type of input signal being used. A line level signal
is typically at least 50 dB greater than a mic level signal.
Input channel 1 has the option to select
AES
as a digital input type. Input channels 1–3
accept either XLR or Phoenix (also known as Euroblock) connectors, while channel 4 only
accepts a Phoenix connector.
Note:
AES stands for Audio Engineering Society 3, a standard for the exchange of digital
audio signals between professional audio devices.
If you select
Mic
as the input, you can specify whether or not the microphone will use
phantom power. Phantom power is electrical power that is sent to a condenser mic
through its mic cable.
