Solid State Logic 82S6MC060A Compressor/Limiter -Introduction, Detailed Parameter Description

Compressor/Limiter –Introduction
The Channel Compressor/Limiter Section has a num ber of
key features including a variable compression ratio from 1:1
to ∞:1, a variable th reshold from	–20dB t o +1 0dB, a uto
sensing attack time ( or selectable	1ms attack t ime), and a
variable release from 0.1 to 4 seconds.
The Compressor/Limiter has two modes of signal detection,
Peak and RM S. As their names suggest these modes		of
detection either act on peaks of the incoming signals or on
their RMS or average l evels. This gives two very different
modes of compression and limiting with Pea k Mode giving
far more dramatic compression characteristics.
Detailed Parameter Description
RATIO: When turned to 1:1, the Compressor/Limiter section
is inactive. Turning the cont rol clockwise i ncreases the
compression ratio to give a true limiter at the fully clockwise
position. T he co mpressor normally has an ‘over-e		asy’

characteristic. Selecting PK changes this to peak sensing, and replaces the ‘o ver–easy’ characteri stic wi th a hard knee, providing an alternative for some instruments. 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 als o provi des autom atic \make-up gain, so as you lowe r 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.
FAST ATT: Provides a fast attack time (3mS for 20dB gain
reduction). When off the attack time is program dependent
(3mS – 30mS).
The yellow and red LEDs, on the bottom of the LED display
area, indicate the amount of gain reduction (compression).
Expander/Gate – Introduction	number o f useful
The g ate/expander section c ontains a
features including a variable range from 0 to 40dB, a variable
threshold f rom - 30dB to +1 0dB, a	f ixed at tack time

(switchable to Fast Attack of 100µs), a variable hold time from 0 to four seconds and a variable release time from 0.1 to 4 seconds.

The sidechain signal is sourced from the signal feeding the dynamics section a nd th e filters a nd/or equaliser c an be inserted in this sidechain. The green LEDs indicate the amount

of gain reduction on the expander/gate.∞ By default, the Gate/Expander section functions as an :1 gate. When the EXP button is pressed, the section becomes a 2:1 expander.
