Because the Surround MultiMeter Goniometer is dealing with multichannel signals, the<br />

display is divided into multiple segm<strong>en</strong>ts, as shown in the image. Each segm<strong>en</strong>t indicates<br />

a speaker position. Wh<strong>en</strong> the surround panner is moved in a channel strip, the indicator<br />

changes accordingly. This indicates not only left and right channel coher<strong>en</strong>ce, but also<br />

the front-to-rear coher<strong>en</strong>ce.<br />

• Goniometer button: Displays the Goniometer results in the main display.<br />

• Auto Gain field: Sets the amount of display comp<strong>en</strong>sation for low input levels. You can<br />

set Auto Gain levels in 10% increm<strong>en</strong>ts, or set it to off.<br />

Note: To avoid confusion with the Auto Gain parameter found in other <strong>Soundtrack</strong> <strong>Pro</strong><br />

effects and processors (such as the compressors), Auto Gain is only used as a display<br />

parameter in the meters. It increases display levels to <strong>en</strong>hance readability. It does not<br />

change the actual audio levels.<br />

• Decay field: Determines the time it takes for the Goniometer trace to fade to black.<br />

• L–R, Ls–Rs, Both buttons: Determine which channel pairs are shown in the main display.<br />

Wh<strong>en</strong> you are using the Surround MultiMeter in configurations with exactly two channel<br />

pairs (quad, 5.1, and 6.1 configurations), the Goniometer can display both pairs if you<br />

select Both. One pair (for L-R) appears in the upper half of the main display, and one<br />

(for Ls-Rs) appears in the lower half.<br />
