1. Input Level Meters
Indicate incoming signal levels. Input level meters
show a minimum when the incoming signal is more
than -48dB digital full-scale. Level meters appear in
inverse video when the signal approaches overload
(-2dB digital full-scale). When signals are between
these extremes, the level meters appear as shown
above.

Input level meters show calibrated values, with 0dB
indicating digital saturation. Markings on the open
portion of each level meter show -6, -18, and -32dB.
The meters have single-pixel precision in which each
pixel represents 2dB.

S/PDIF digital input sources that have been mastered
"hot" (at the maximum bit rate) will cause the input
level meters to peak as if digital full-scale is
6
occurring. However, the unit is just receiving the
maximum output from the source, which is loud
enough to peak the meters. This is not a problem as
long as the source audio is not distorted.
Gain reduction from the compressor is indicated by
a descending bar situated between the two input
level meters. It is also calibrated in 2dB increments
per pixel.
2. Input/OVL Indicator
Reflects the input type in normal operation. The first
letter indicates input type, which is selected with the
System Mode parameter Input Source (see page 3-4).
