User Manual

The Comp FET-76 doesn't have a Threshold control. Threshold changes according to the
chosen compression ratio. This is because, although we can define the compression ratio
(among the available choices) the compressor is still program dependent. This means that
it reacts differently according to the audio that feeds the circuit.

♪: To better find the right compression settings, first define the desired Ratio, and then slowly raise
the Input value. Since Input and Output are tied (linked), you may notice a decrease in the resulting
volume when compression starts to be applied. If you want, you may raise the Output volume to
compensate.
Since the unit has some coloring induced, it still has some impact in the sound, even if it's
not applying any compression.
4.2.2. Link
The Link switch connects the Output control to the Input control. It is a toggle switch, which
is On by default. The control is labeled with a picture of a chain.
When Link is On, each time we move the Input control, the Output control moves in the
opposite direction. Since the compressor is program dependent, we may be tempted to drive
the signal really hot. This way we can drive Input (and compression) like crazy without
risking overloading the audio chain.
We can always move the Output independently, since the link only works from the Input to
the Output, and not the other way. Therefore, after we find the ideal Input level to achieve
the desired compression, we can then check for the right Output gain without changing the
Input.
If we turn Off this control, both Input and Output can be changed independently of each
other.
Comp FET-76 Input and Output controls at
the default position. We may see the Link
switch in the bottom, between the two
knobs
