THE BLOCKS
28
Soft Compressor
This is a feed forward compressor.. It sounds very smooth
and works well on acoustic and electronic instruments.
Threshold
When the input level exceeds the Threshold, the Compressor
will be activated. This means that the lower the Threshold, the
more compression you will get.
Ratio
The Ratio of the gain reduction. E.g.: When the Ratio is set to
4:1 it means that for every 4dB the input level rises, the output
level increases by only 1 dB.
Attack
The Attack time is the response time that the Compressor uses
to reach the gain reduction specified by the Ratio parameter.
Example: If the input signal suddenly increases to 4dB above
threshold in no time with the Ratio set to 4:1 and the Attack
set to 20 ms, the Compressor will use 20 ms to reach the gain
reduction of 1 dB.
Release
Release sets the fall back time of the Compressor, after the
signal drops below the Threshold.
Knee Mode
The Knee Mode parameter sets the bending point of the
compressor to soft knee or hard knee. When soft knee is
selected, the Compressor will gradually reach the ratio, while
hard knee will cause the Compressor to go directly from no
compression to the set ratio.
Output
Output adjusts the output gain after compression, to
compensate the loss of level caused by the compression.
SIDECHAIN
The Sidechain is the reference signal that the Compressor is
listening to internally for processing. You will never hear this
signal on the output.
Input
When placed on Channel 1, you can select the Sidechain Input
to be either the Same (Ch.1) or Channel 2.
Example: If you select to have Sidechain input from Ch.2, you
can go to the Layout page and select Ch. 1 Pre, as input to
Ch.2. Now you have all the blocks on Ch. 2 for processing the
Sidechain signal on Ch. 1. You can also have a completely
different input on Ch. 2.
NOTE: When two blocks are linked, you cannot select Ch. 2
as input for Ch. 1 Sidechain.
Vintage Compressor
This compressor is a bit more specialized and “vintage”- like.
It is a very musical compressor that sounds especially good on
vocals.
It’s a feedback type compressor which means that it gets its
Sidechain input from its output, and therefore it is not possible
to have another separate input to the Sidechain.
Input Drive
The Compressor works with a fixed threshold at -24 dB, so the
Input Drive is meant for adjusting the input level to fit this
threshold.
Example: The more you boost the Input Drive, the more you
will exceed the fixed threshold, and you will get more
compression.
Output Gain
Output Gain adjusts the level after the compression, enabling
you to compensate for level jumps through the Compressor.
Ratio
Adjusts the Ratio of the gain reduction.
Example: When the Ratio is set to 4:1 it means that for every 4
dB the input level rises, the output level increases by only
1 dB.
