5.1 Fat Channel Navigation
5.1.3.3 Class-A FET Leveling Amplifier
4. Key Filter. This encoder sets, and the scribble displays, the frequency at which
the Tube Leveling Amplifier will engage. It will still process the entire frequency
range, but it is only engaged when the specified frequency is present. Press
the button below to listen to the signal being used to trigger the compressor
(including the effects of the high-pass filter, as set with the Key Filter control).
Press again to switch back to the normal channel signal.
Press the Processor button to turn the Compressor on or off.
When the Fat Channel is in Tube Compressor mode, the touchscreen shows an
overview screen that displays the relevant parameters (as available in the Fat
Channel). Touching any onscreen knob allows you to use the Master Control encoder
to set the selected parameter. Touching a drop-down selector (such as Key Source)
lets you select from a list of relevant choices. Use the Master Control encoder to scroll
through choices. Touching onscreen buttons toggles the related parameter on or off.

1. Processor On/Off. Enables or disables the Compressor.
2. Comp / Limiter. Switches between the compressor and limiter modes.
3. Gain. Sets the input gain to the compressor.
4. VU Meter. Displays the post-Compressor signal level.
5. Peak Reduction. Sets the amount of peak reduction to apply to the signal.
6. Key Filter. Sets the Key Filter frequency.
7. Key Listen. Touch to enable the Key Listen function.
8. Key Source (Input Channels only). Sets the Key Source for the Compressor.
When the Class-A FET Leveling Amplifier is selected, the following controls are
available in the Fat Channel:

1. 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.
2. 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 compression occurs.
3. Attack. Sets the time it takes for the compressor to begin attenuating a signal
once it passes the threshold.
4. Release. Sets the time it takes for the compressor to stop attenuating a signal
once it falls below the threshold.
5. Ratio. Sets the Ratio for the compressor. The following Ratios are available: 4:1,
8:1, 12:1, 20:1, or All.
