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.
