Mix-point Gain

DSP Configurator provides control of the mixer that is used to mix the line input and microphones to the outputs. Each of the microphone and stereo line inputs is connected to a mix-point for each of the outputs. In general, mic mix levels are set relative to the source program material connected to the output and also relative to other microphones. The default setting for mic mix-points is unmuted at unity gain (0.0 dB).

See the Optimizing Audio Levels section for more information.

Adjusting Mix-point Gain

Mic mix-point behavior is as follows:

  • No mix information - A solid gray circle indicates that the
    mix-point exists but does not contain any mix information (the mix-point is muted).

  • Mix information - A solid teal circle indicates that the mix-point contains mix information (the mix-point is unmuted). When one channel is mixed (either the left or right channel), one-half of the circle is shaded teal, representing the unmuted channel. The other half of the circle is gray, representing the muted channel.

  • Mouse-over - When you hover the cursor over a mix-point, the cursor changes to a hand tool.

  • Single-click - A single click brings focus to (selects) the mix-point. This is indicated by a dark green outline around the circle.

  • Double-click - Double-clicking the mix-point opens the Mix-point dialog box. The focus outline becomes light green for an open dialog box.

  • Multiple open dialog boxes - When multiple mix-point dialog boxes are open, the mix-point for the most recently opened dialog box has a light green outline. The previously opened dialog boxes do not have a focus outline.

Mix-point Dialog Box Components

To open the mic Mix-point dialog box, double-click a mic mix-point. You can use this dialog box to adjust the mix levels to the left and right stereo bus. The gain range is
-24 dB to +12 dB.

Each mix point has upper and lower soft limits that can be used to limit the range of the control. These soft limits default to the inherent "hard" limits for the mix level control.

To define the upper and lower soft limits, click and drag the upper and lower soft limit handles. The soft limit resolution is 0.1 dB.

In the mix-point dialog box, you can view the level or mute status of the mic input GAIN block. The reported information can be used as a reference when setting mix-point levels.

To mute the signal individually to the left and right of the stereo bus click the associated Mute button.

A Gang button couples the left-channel and right-channel Mute buttons. If one channel is muted, the other channel is muted as well. The Gang button is shaded green when the two Mute buttons are ganged.
