Figure 2: Compressor Section of the front panel
+ 0 - THRESHOLD leds:
¨
The Ò+Ó led illuminates when the signal is above the OverEasy portion of the compression curve
¨
and that the full compression ratio is in effect . If OverEasy is disabled, this led indicates that the
signal is above the level set by the Compressor Threshold control and that compression is occuring.
¨
The Ò0Ó led illuminates when the signal is in the OverEasy portion of the compression curve. In this
region the ratio varies as a function of signal level between 1:1 and the ratio set by the Ratio control.
¨
This led will not light when the OverEasy function is off.
The Ò-Ó led illuminates when the signal is below the level set by the Compressor Threshold control.
This indicates that the Compressor is not compressing and is operating in its linear region.
THRESHOLD control:
This control sets the level above which compression occurs, and has a 60 dB range.
¨
OverEasy switch:
¨ ¨
OverEasy is a feature that provides a softer compression sound than hard knee does. OverEasy
smooths the transition from un-compressed to compressed. This smooth transition greatly reduces
compression artifacts and allows faster attack times and higher compression ratios while still main-
¨
taining the natural characteristics of the signal. The switch lights to indicate OverEasy processing is
¨
enabled. When conventional hard knee processing is desired, disable the OverEasy function. See
¨
Figure 3 for a comparison of OverEasy and hard knee compression curves.
