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”.
