FINALIZER D.C. 30
Expander
Signal levels below the Expander Threshold will be lowered according to the Expander
Ratio. If the Ratio is set at 1:2, 1dB of level drop on the input will result in 2dB level drop
on the output. If you want to turn off the Expander, set the Threshold at OFF.
For high Ratios, the Expander becomes a Gate. For low Ratios, Expansion is subtle and
may be used to counteract the gain applied in the Compressor section, thereby preventing
noise floor build up. The Expander Range is set based on the value of the Ratio.
Expander Attack time is set based on Look-ahead Delay.
Expander Release time is set based on Target Type.
Compressor
Signal levels above the Compressor Threshold are lowered according to the Compressor
Ratio. If the Ratio is set at 3.2:1, 3.2dB of additional input level is needed to make the
output rise 1dB.
Threshold and Ratio in the Low and High band is based on the Mid band settings, and how
the Target Type and Target Factor is set.
If you want to turn off the Compressor, set the Threshold at OFF.
Make-up gain is automatically calculated and applied as a function of Threshold and Ratio.
Compressor Attack time is shown for the Mid band. Release times for the Low and High
band depend on the Mid band Release and the Target Type setting.
Compressor Release time is shown for the Mid band. Release times for the Low and High
band depend on the Mid band Release and the Target Type setting.
Band Levels
The levels on each of the three frequency bands are controlled on the Lo, Mid and Hi
faders. The levels are adjusted at the output of the compressor, prior to Limiter and Soft
Clipping circuitry.
Limiter
Limiting takes place above the Limiter Threshold. Thresholds in the Low and High band is
based on the Mid band settings, and how the Target Type is set.
If you want to turn off the Limiter, set the Threshold at OFF.
Limiter Attack time is based on the Target Type setting and the Look-ahead Delay. Attack
times are always much faster than in the Compressor section.
Limiter Release time is based on the Target Type setting.
Soft Clip
When the three frequency bands of the Expander, Compressor and Limiter are re-
combined, overshoots may result. To control these transients in a gentle way, a Soft
Clipping circuit with selectable Threshold is included in the Finalizer D.C..
Watch the Soft Clip meter to make sure, that Soft Clipping is only active at signal peaks,
unless you like a slight distortion to be added to the basic components of your signal.
