1 – Settings (Sonalksis logotype): Click this button to access the Preferences (Settings) panel.
2 – Meter: The meter displays a current indication of signal level. The main display is a classic Peak-type level meter, which follows the signal in accordance with the metering type selected on the Preferences panel. The superposed red bar displays the current instantaneous signal RMS.
3 – Pre: Selecting ‘Pre’ switches the fader to display the pre-fader, pre-pan, pretrim input signal.
4 – Fader: The fader is the main plug-in control, and allows you to adjust the level of the incoming signal. Hold ‘SHIFT’ to fine-adjust the level, or enter a value in the textbox beneath the fader. Double click, Alt-click or Ctrl-click (Win)/Apple-click (Mac) to reset the fader.
5 – PEAK: This box, and the red arrows on the meter, displays the current highest peak value recorded (using the metering law configured on the Preferences panel). Click boxes to reset.
6 – RMS: This box, and the yellow arrows on the meter, displays the current highest instantaneous RMS value recorded. Click the boxes to reset.
7 – Trim: The Trim dial provides a course input level adjustment. The Trim range can be configured using the preferences panel. Hold ‘SHIFT’ to fine-adjust the level, or enter a value in the textbox beneath the dial. Double click, Altclick or Ctrl-click (Win)/Apple-click (Mac) to reset the dial.
8 – Pan (not applicable in mono version): The Pan dial allows a stereo signal to be panned to the left or to the right. The Pan law is configured using the preferences panel. Hold ‘SHIFT’ to fine-adjust the setting, or enter a pan position in the textbox beneath the dial. Double click, Alt-click or Ctrl-click (Win)/Apple-click (Mac) to reset the dial.
9 – Flip Phase: The Flip Phase button inverts the phase of the signal, for mixing applications.
10 – Bypass: The Bypass button provides a soft-bypass for the plug-in.
11 – Mute: The Mute button will mute the signal.
12 – Fine: Fine mode allows for an alternate method of fine-calibration of the fader. When the fader is set approximately, pressing ‘Fine’ will ‘zoom in’ on the fader, and offer a linear-law fader, which you can adjust with greater accuracy. The range of the Fine scale can be configured in the Preferences panel.
