FULL-RANGE MODE
Full-range mode is the mode typically found in standard
Compressors. Threshold, Ratio, Attack and Release
settings apply for the entire frequency area.
To select the Full-range Mode
ENVELOPE MODE key LED must be off/unlit.
MULTI-BAND OFF LED must be lit.
Input Section
Input Level
Adjusts the Input level of the TRIPLE•C. Play your source
material through the TRIPLE•C and observe the Input
meters in the display. Correct operation level is approx -6
to -3dBs with an occasional peak at 0dB. If the Input signal
at any time overloads, - reduce the Input level.
Dynamic Section
Threshold
When the signal is above the set Threshold point the
Compressor is activated and the gain of any signal above
the Threshold point is processed according to the Ratio,
Attack and Release settings.
Ratio
The Ratio setting determines how hard the signal is
compressed. (see illustration above).
Example:
With a Ratio setting of 2:1 an Input signal at 4dB
above Threshold is reduced to only 2dB on the Output-side.
Attack
The Attack time is the response time of the Compressor.
The shorter Attack time the sooner the Compressor will
reach the specified Ratio after the signal rises above the
Threshold point.
Release
The Release time is the time it takes for the Compressor to
release the gain reduction of the signal after the signal
drops below the Threshold point again.
Softlim
Softlimiter on/off switch. Where the Compressor mostly is
used to gradually reduce the dynamic content above the
set Threshold point a limiter is used to directly avoid hitting
the upper limit of 0dBFS. Compressors and limiters are
often used in conjunction. - The Compressor as the musi-
cal/gentle way of reducing the level and the limiter as a
hard abrupt control to avoid distortion. See illustration.
In Full-range mode the controls in the Spectral
adjust section have no effect.
Look Ahead
The Look Ahead delay function is not available in the
Full-range mode
Makeup Gain Section
Bypass
Press to bypass the TRIPLE•C. All processing parameters
are bypassed. Input Level control and all System settings
found in the I/O menu are not bypassed.
Level
When a signal is compressed, the maximum Output level
of the signal is reduced. Since it is a reduction in dynamic
content and not a gain-reduction that is the object of
applying compression a make-up gain is necessary to lift
the signal to appropriate level. Observe the gain reduction
via the meters and lift the processed signal to approximately
0dB using the Level knob in the Make Up Gain section.
For detailed information please read the section on make
up gain in the section called “Using Compression”.
