Tube Leveling Amplifier
1. On/Off. Turns the Compressor on or off in the signal chain.
2. Gain. Sets input gain to the compressor. Because this type of compressor operates in a different way
than a standard compressor, much of the way that it affects signals is based on the input level. Try dif-
ferent settings to see what suits your needs.
3. Peak Reduction. Sets the amount of peak reduction to apply to the signal. Higher settings result in
more gain reduction and more pronounced compression effect.
4. Compressor/Limiter Toggle. The button below toggles the Tube Leveling Amplifier between its
compressor and limiter modes. When in compressor mode, it acts with a variable ratio of 1:1-10:1.
When in limiter mode, it acts with a variable ratio of 10:1-20:1, more aggressively limiting peaks.
5. Key Filter. This sets the frequency at which the Tube Leveling Amplifier will engage. It will still pro-
cess the entire frequency range, but it is only engaged when the specified frequency is present.
6. Key Listen. Press to listen to the signal being used to trigger the compressor, as set with the Key Fil-
ter control (including the effects of the high-pass filter). Press again to switch back to the normal chan-
nel signal.
Class-A FET Compressor
1. On/Off. Turns the Compressor on or off in the signal chain.
2. Input Gain. Sets input gain to the compressor. This setting affects the action of the compressor, so
feel free to try various settings to find the optimal effect for your needs.
3. Output Gain. Sets the amount of "makeup gain" to apply to a signal. Once a signal is compressed, its
overall level is often reduced. This gain control lets you bring it back up to the proper level after com-
pression occurs.
4. Attack. Sets the time it takes for the compressor to begin attenuating a signal once it passes the
