2.Peak Expansion Meter

Indicates the level of peaks above the peak expansion threshold. Low-level peaks are shown as one or two graduated bars. Slightly higher peaks of longer duration are shown as three graduated bars. High-level peaks are shown as three solid bars.

4.Input Meter

When the Meters parameter is set to In, indicates the maximum left or right channel input levels, whichever is greater. The associated tick marks are placed in 3dB increments. The right-most tick mark indicates 0dB or maximum input level.

Note:

Use the Meters parameter to select between gain reduction and input level metering.

3.Gain Reduction Meter

When the Meters parameter is set to GR, indicates the output level reduction due to compression. The value shown indicates the maximum left or right channel gain reduction, whichever is greater.

The meter moves from right to left. The tick marks are placed in 3dB increments. The right-most tick mark represents 0dB or no gain reduction. Each tick mark proceeding from right to left indicates an additional 3dB of gain reduction.

TYPICAL MASTERING DYNAMICS CONTROL ADJUSTMENT

The following is a common scenario for musical sources that have not previously been compressed:

For analog input sources, adjust the front panel Input Trim knob so the input meters peak in the -6dB range. The input meters should never exceed the 0dB level.

Beginning at 0dB, reduce the setting of the ExpThrsh parameter until peaks in the source material cause the peak expansion level meter to show 1 to 3 graduated bars. High-level peaks in the sound source
