Dynamics
The output channel dynamics block provides a limiter function (see the diagram below)
that restricts the input signal level by compressing its dynamic range above a specified
threshold. The limiter is most commonly used to prevent clipping, protecting a system
against component or speaker damage. While the limiter is closely related to the
compressor, it applies a much higher compression ratio of ∞:1. The ratio is fixed and
cannot be changed.
Volume
Each output channel volume block (see the following diagram) 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 a
value directly into the field in 0.1 dB increments. Using the arrow buttons on the keyboard
provides 1 dB increments.
An individual Mute button provides control of channel muting. Output polarity switching is
also provided with a button that toggles between positive (+) and negative (-) 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 single click, while the Cancel
button ignores changes and closes the dialog.
