Fredenstein F602 Tube Compressor
User Controls:
Threshold Control:
Determines the input level at which the compressor is activated. If turned completely counter
clockwise, a switch engages and the compression is turned off.
Compression Ratio:
The amount of increase in output level relatively to the threshold level. Minimum is 2:1, maximum
is 20:1 (limiting).
Release Control:
If the signal drops below threshold, the release time determines how fast the compressor falls back
to 0 dB gain reduction. If turned completely counter clockwise, a switch engages and the release
time is set to automatic mode depending on the program material. The range is 12 ms to 5s.
Attack Control:
Determines how fast the compressor reacts to signals above threshold.
Mix Control:
The mix control allows the user to select a ratio between the compressed and uncompressed signal.
If turned completely counter clockwise, a switch engages and only the compressed signal will be on
the output, if turned completely clockwise only the uncompressed (input) signal is present on the
output.
Level Control:
Make-up gain can be applied in the range of 0 to + 20dB to compensate for the gain reduction.
