7.19 Gain Reduction Metering
When the Meter Select is toggled into “G.R.” the bi-color LED meter is programmed to indi-
cate a bar graph from left to right but differing from the program level indications. In this case,
the bar is entirely green except for a possible red dot which floats within the green bar. The
entire length of the green bar indicates total gain reduction of the Compellor. The position of
the red dot indicates the amount of Leveling gain reduction, if any. The amount of gain reduc-
tion contributed by compression is inferred from the remainder of gain reduction indicated
above the red dot.
If all gain reduction is due to compression, then the indication will be a totally green bar, and
the whole bar indicates compression. If all the gain reduction is from leveling, then the green
bar will have a red dot at the right most point. Figure 7-2 shows an example of indicating
16dB total gain reduction with 4dB of leveling. 12dB of compression is therefore inferred.
