●Compressor settings window Clicking on the compressor button brings up the compressor menu. In the compressor menu you can set the parameters of the rms compressor. You can set the threshold, attack, hold, and release time, the compression ratio and the make-up gain. Next to the controls is a VU meter that also displays the gain reduction (GR).  Be sure to use the ‘Back’ button to return to the output menu.

Even if Input channels are set to Linked in the Unit window, it is still possible here to mix individual Input channels to an Output channel in any desired ratio. Level setting are shown numerically below each fader. The available range is from -48 dB to 0 dB. As in other screen, double clicking a fader resets it to default.

A complete control screen is available for each Output channel. The graphical area reflects the Crossover settings for the channel in addition to any equalization settings set up in this screen, and is very similar to the available settings in the individual Input channel screens.The status of an element is always reflected in the blue on/off button next to each element.
