Soft Soft This being a Soft Soft-Knee type compressor which is very transparent. In Soft-
TYPE
Knee mode however, the compression ratio increases as the signal level
increases and so there is no hard and fast threshold as such. In Soft-Knee,
the THRESHOLD parameter is used to adjust the amount of compression,
and RATIO alters the curve of the knee, making it softer or harder on a
scale of 0 to 9.
COMPRESS PATCHES
Patches numbered 73 through and including 80. These patches have
different time constants associated with the 'hidden' AUTO-Attack, AUTO-
Hold, and AUTO-Release. These times are available for different
programme material, eg. patch 80 would be good on dynamic classical
music mixdown, patches 76 or 77 would be good on a dance, high-energy
type mixdown.
ADVANCED LIMIT
Again requiring only one parameter screen, the Limiter has variable Threshold, Ratio, Attack, Hold
and Release. The principle is similar to that of the Compressor except that the Ratio range is
greater. Limiting is useful in conjunction with a Compressor which may be set up with a long
attack time. In these circumstances, the Compressor may allow short transients through
unchecked, but a fast attack Limiter following the Compressor will prevent these transients from
exceeding the desired amplitude. The Threshold parameter will effect the operation of the
Compressor auto threshold feature, even if the Limiter is not assigned.

THRESHOLD is the level of input signal over which Gain Reduction will
THRESH
start to occur. Often this parameter will be set to just below the maximum
recording level or maximum system level depending on M500
implementation. The parameter range has been logically restricted to
-10dB -10dB through to +18dB +18dB
The LIMIT THRESHOLD parameter will also effect the operation of the
COMPRESSOR
Auto Auto THRESHOLD feature, even if the LIMITER is not
assigned.
The RATIO setting determines how much Gain Reduction occurs when the
RATIO
input signal goes above THRESHold. The parameter range covers from 2: 2: 1 1
to 90:1 90:1
The amount of Gain reduction (Limiting) depends upon the THRESHold
and RATIO settings and the signal level. eg. A signal of +10dB with a
THRESHold setting of 0dB with RATIO set to 90:1 will give an output level
of 0dB.
