Controls the decay speed of the peak detector used by the dynamics processing.

SLOW
Controls the amount of gain slewing which will general slow up the response to
attack transients only.
 CMP RATIO
: (value range:
1.0:1
to
5.0:1
, step:
.
1
)
3.0:1
Compressor ratio. Sets the compressor ratio i.e. 2.0:1 means for every 1 dB
above the compressor threshold the gain will be reduced 2 dB
 CMP THRESH
: (value range:
0
to
–96dB
, step:
1
)
-20dB
Compressor threshold. Sets the threshold below which grain reduction occurs
according to the compressor ratio setting.
 CMP KNEE
: (value range:
0
to
20dB
, step:
1
)
0dB
Compressor soft knee setting. Sets the "depth" of the compressor's soft knee. A
soft knee of 6 dB will result in more gradual gain reduction in the 6 dB range over
the compressor's set threshold. Note that settings below 6 dB have very little
effect.
 EXP RATIO
: (value range:
1:1.00
to
1:4.00
, step:
.
01
)
1:1.10
Expander ratio. Sets the expansion ratio i.e. 1:2.0 means for every 1 dB below
the expander threshold the gain will be reduced 2 dB.
 EXP THRESH
: (value range:
0
to
–96dB
, step:
1
)
-40dB
Expander threshold. Sets the threshold below which gain reduction occurs
according to the expander ratio setting.
 REDUCE
: (value range:
0
to
–36dB
, step:
1
)
-12dB
Maximum amount of expander gain reduction. Sets an absolute limit on the
amount of gain reduction caused by the expander.
 GAIN
: (value range:
0
to
30dB
, step:
1
)
0dB
Make up gain setting. Used to compensate for the gain reduction caused by the
action of the compressor.
Dynamics comprises both a compressor and an expander, which operate jointly.
The compressor in Dynamics can perform mild or extreme compression and features a soft knee for more
transparent operation. The expander in Dynamics can perform subtle or extreme noise reduction.
Note that the Dynamics processing is done before the existing Expander (which is still functional). Thus, the
expander can be used as a stand-alone noise gate while the dynamics can shape the sound as desired.
ADC Location page
ADC: INTERNAL
Page purpose: This page indicates where the analog to digital conversion (ADC) is performed.
Parameters:
 STA-150
– AD conversion is done in the attached STA-150.
 STA-100
– AD conversion is done in the attached STA-100.
 INTERNAL
– AD conversion is done internally for use with the mic input connector.
NOTE:
External
only applies when an STAxxx is attached.
