Volume Control (VOL)
Each output channel volume block provides a mono long-throw
fader with a range of 0 to 100 dB of attenuation, and a volume
setting readout (in dB) below the fader. Volume level is adjustable
with the slider or by entering the desired level directly into the
volume setting readout in 0.1 dB increments.
Clicking the fader handle or clicking within the fader area brings
focus to the fader. The input signal level can be adjusted using any
of the following methods:
• Click and hold the fader handle, then drag it to desired level in
1.0 dB steps.
• Click or tab to the fader handle, then use the <up> and <down>
arrow keys to change the desired level in 1 dB steps. The
keyboard <Page Up> and <Page Down> keys increase or
decrease the level in 5 dB steps.
• Click in or tab to the level readout field. Type a new value, then
press
<Enter> or <Tab> to another area.
Output polarity switching is also provided with a button that toggles polarity.
The default setting is unmuted, at 0 dB attenuation. A peak meter displays the real-time
audio level from – 60 to 0 dBFS.
The
OK button accepts settings and closes the dialog with a click. The Cancel button
ignores changes and closes the dialog.
The output volume control provides level control for each output. The output control is a
trim control adjustable from – 100.0 to 0 dB. The default setting is unity gain (0.0 dB).
The
Polarity button, accessible in the dialog box, allows the polarity of the wires
connected to the audio connectors (+/tip and -/ring) to be flipped in order to easily correct
for miswired connectors.
The
Mute button, accessible in the dialog box, allows the post-meter audio output to be
silenced. When the audio output is muted, the mute button lights red, and red indicators
in the block turn on. If the output has been grouped with other inputs or outputs, the
group number will be indicated on the right side of this button.
