Meter
The Meter switch specifies the signal source for the main stereo meter, either
input or output.
Input
When the Meter switch is in Input mode, the main level meters display the signal
level at the input of the plug-in (and is not affected by the Input knob).
Output
When the Meter switch is in Output mode, the main level meters display the
level at the output of the plug-in. When the Limiter is enabled, the Output and
Input knobs will affect this display.
Scale
The meter Scale switch increases the resolution of the main stereo level meter
(See Figure 40 below). The meter range that is displayed in Normal and
Zoom modes is dependent upon the meter Type setting (see “Type” on
page 147).
Figure 40. Precision Limiter meter scale in PK-RMS Zoom mode
The main level meters in Normal mode, and the gain reduction meter in both
Normal and Zoom modes, are linear (level differences between LED segments
is the same). In PK-RMS and K-20 Zoom modes however, the main level
meters use two different linear ranges for increased accuracy.
The ranges and response for each meter type and scale is detailed below.
PK-RMS
In Normal mode, the meter range is –60dB to 0dB with a linear response of
0.5dB per segment. In Zoom mode, the range is –18dB to 0dB with two different
linear responses: 0.2dB per segment from –18 to –6dB, and 0.1dB per
segment from –6 to 0dB.
