Solid State Logic SL 9000 J SERIES User Manual

THRESHOLD – Whenever a signal exceeds the level set by
this control, the compressor will start to act at the ratio set by
the RATIO control. This control also provides automatic make-
up gain, so as you lower the threshold and introduce more
compression, the output level is increased, maintaining a
steady output level regardless of the amount of compression.
RELEASE – Sets the time constant (speed) with which the
compressor returns to normal gain settings once the signal has
passed its maximum. The control also incorporates a pull
switch which, when selected, provides a fast attack time (3mS
for 20dB gain reduction). When down the attack time is
program dependent (3mS - 30mS).
The yellow and red LEDs, on the right of the LED display area,
indicate the amount of gain reduction (compression).
Expander/Gate
This section can act as a ":1 Gate or as a 2:1 Expander when the HOLD pot is pulled
upwards. A red LED indicates that Expand mode has been selected.
RANGE – Determines the depth of Gating or Expansion. When turned fully anti-
clockwise (Range = 0), this section is inactive. When turned fully clockwise, a Range of
50dB can be obtained.
THRESHOLD – Variable hysteresis is incorporated in the Threshold circuitry. For any
given ‘open’ setting, the Expander/Gate will have a lower ‘close’ threshold. The
hysteresis value is increased as the Threshold is lowered. This is very useful in music
recording as it allows instruments to decay below the open threshold before Gating or
Expansion takes place.
