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.
