Playback Strips; Adjusting Playback Volume - Echo Indigo dj Owner's Manual

At the top is the peak meter for this channel, labeled in decibels. Under the
peak meter is the monitor pan slider; this pans the input channel between the
two channels of the output bus. Holding down the Ctrl key and clicking on a
pan slider will set the slider to the center position. Note that this does not
affect your recording. Below the pan slider is the monitor mute. This
controls whether or not you want this input channel to be mixed directly out
to the currently selected output bus. Again, this does not affect recording.
This is followed by the monitor fader, which controls the input monitor
level. Like the pan and mute controls, this does not affect your record level.
Also, clicking on the readout below the fader will allow you to numerically
enter a fader setting.
The analog inputs also have gang buttons, and their operation is the same as
the gang button for the master outputs.

Playback Strips

The controls for the level of audio being played by an application are found
in the middle of the Console and have the label "Virtual out" at the bottom.
Each Indigo Console has multiple playback strips – one for each virtual
output. Each playback strip allows you to pan, mute and change the level of
the audio signal that is being sent to your Indigo product's physical outputs.
Each virtual output can be mixed in any combination to your Indigo
product's analog outputs.

Adjusting Playback Volume

Output volume adjustments are made in the digital domain. When you lower
a volume fader below 0dB, you are actually decreasing the number of
available bits, thereby taking away from the potential dynamic range of the
system. Therefore, we suggest that whenever possible you leave the output
faders set to 0dB, and perform any necessary attenuation with the volume
knob on your Indigo product or with an external mixer. When the playback
volume controls are set to 0dB and the input signal approaches the
maximum pre-clipping level, you can achieve the full 24-bit dynamic range
of the system.
