MULTI-BAND MODE

Multi-band mode - is a 3 band compression mode. By dividing the source material into 3 frequency areas you can avoid that peaks at certain frequencies controls the compression of the entire signal. By setting the Lo and Hi Cross-over frequencies you determine the range of the Frequency areas.

To select Multi-band mode

•ENVELOPE MODE key LED must be off/unlit.

•MULTI-BAND OFF LED must be unlit.

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 -3dB with an occasional peak at 0dB. If the 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).

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.

Peak Type

The TRIPLE•C is basically an RMS based Compressor, meaning that it responds to the average level of the incom- ing source material. This key turns the TRIPLE•C into a Peak based Compressor. When the key LED is lit the TRIPLE•C is in Peak mode. Peak mode is the general choice when processing percussive material. This feature is only available in Multi-band mode.

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 an upper limit. Compressors and limiters are often used in conjunction. - The Compressor as the musical/gentle way of reducing the level and the limiter as a hard abrupt con- trol to avoid distortion. See illustration.

Look Ahead

Press to activate the 3ms Look-ahead delay. This gives an even better and more precise compression performance of the TRIPLE•C. - 3ms is approx the time it takes for sound to travel 1 meter.

Spectral Adjust

Lo-Freq & Hi-Freq Controls

Applying the same Ratio, Attack and Release settings for both Lo, Mid and Hi bands will often result in an un-even Output frequency balance. With the Lo-Freq and Hi-Freq controls you can adjust the Output level of the Lo and Hi-Frequency bands.
