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. 
 

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 

 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 

 button accepts settings and closes the dialog with a single click, while the 

 

button ignores changes and closes the dialog.
