Detailed Parameters Section 4

4.12 Ambience

Ambience uses a combination of gain and compression to enhance low level information. Reverb tails and acoustic guitar finger picking are examples of sounds that can be enhanced by using the Ambience effect.

Ambience On/Off

Sort of self explanatory by now.

Amount 1.0:1 to 5:1

This sets the amount of ambience.

Width 10 to 30 dB

This controls the portion of the signal that the ambience is applied to.

Thresh -60 to 0 dB

Sets the threshold of the ambience processor.

4.13 TCM™

Transient Capture Mode or TCM™ was first seen in the dbx 172 Super Gate. Basically what it does is delay the input of the VCA enough that the detector is able to read ahead in the signal. With a long enough TCM™ time it is possible to have a gate start to open or compressor start to compress before the signal hits the VCA. This can be used to achieve very intelligent limit- ing and gating along with very smooth and transparent compression. Once the TCM™ is turned on it works on the compressor, gate and limiter while in both multiband and broadband modes. To keep the multiband dynamic elements phase coherent, there is only one TCM™ time for all bands of the gate, compressor, and limiter.

TCM™ On/Off

This is a global control and turns the TCM™ on or off for all compressors, limiters, and gates.

Time 0 to 85 m Sec

This sets the amount of the TCM™ delay. The longer the time, the more time the unit has to react to fast transient peaks. Care must be used however as a long TCM™ time coupled with a fast release on the compressor or limiter can cause them to release before the peak even hits.

4.14 De-Esser

The De-Esser is only available in non-multiband chains, e.g., Stereo Broadband or Dual Mono. A De-Esser is primarily used to remove the "S" or sibilant sounds in a vocal track.

Within the De-Esser menu the following parameters are user adjustable:

De-Esser On/Off

You guessed it. Turns the De-Esser on or off

Freq. 800 Hz to 8.00 kHz

This is the center frequency the De-Esser uses when in Band Pass mode or the corner frequency used when in High Pass mode.
