Each band meter is showing the gainreduction of the compressor to the right of the meter
center-line and the gainreduction of the expander to the left of the centerline. Whenever the
limiter of that particular band is in action a black square is shown at the end of the meter.
Illustrated above is thus an expander gainreduction of 2 dB in the low band, no action in the
midrange and 2.5dB compression in the high band as well as limiting taking place.
PAGE 4 - COMPRESSOR:
C-THRSH -40 dB - 12 dB Compressor threshold with auto makeup
function. (Very useful if a there is low
level at the digital inputs. You may think
of this as a "drive" control for this
purpose). Thresholds are relative to the
'0dB ref' as shown on figure 4.
C-RATIO off - 1.12:1 - infin:1 The ratio of the compressor can be
adjusted from off (1:1) to infinite gain
reduction.
C-GAIN Read Only Displays the auto make-up level.
Lowering the threshold and/or increasing
ratio on a compressor will normally
result in a reduced (i.e. compressed)
output level. DYNAMIC1 automatically
adjusts (make up) the compressor output
level in order not to loose signal level.
C-GAIN will display this make up gain
value, which is calculated to uphold a
unity gain at a '0 dB reference' level of
your choice.
