Engage Button
-------------

.. image:: in.png

When turned off, whole processing of the plugin is bypassed.

--------------
Comp In Button

.. image:: comp_in.png

When turned off, reduction is not applied to input signal. Tone processor keeps working regardless of this setting.

---------------
Reduction Meter
---------------

.. image:: reduction_meter_vu.png
.. image:: reduction_meter_peak.png

VU
    White line indicates current reduction amount, in VU ballistic. Blue triangle indicates output gain.
Peak
    Momentary peak reduction amount is displayed by segments. The meter behaves as quasi peak program meter with 3 msec integration time.

----------
Color Lamp
----------

.. image:: color.png

Color lamp indicates the amount of processing under nonlinear part of internal tone processor.

----------
Input Knob
----------

.. image:: input.png

Input Knob controls the gain applied to input signal.

--------------
Threshold Knob
--------------

.. image:: threshold.png

Threshold Knob controls signal level that the compressor starts to apply reduction.

-----------
Output Knob
-----------

.. image:: output.png

Output Knob controls the gain applied to output signal.

-----------
Ratio Knob
-----------

.. image:: ratio.png

Ratio knob controls the factor of gain reduction amount.

-----------
Attack Knob
-----------

.. image:: attack.png

Attack Knob controls time to start applying reduction after input signal exceeds threshold.

------------
Release Knob
------------

.. image:: release.png

Release Knob controls time to stop applying reduction after input signal becomes lower than threshold.

---------
Link Knob
---------

.. image:: link.png

Link knob controls amount of inter-channel synchronization of reduction curve.

--------
Mix Knob

Indicates peak level of side chain signal. When external side chain is available and selected, segments color becomes orange.

-------------------------
Side-chain Monitor Button
-------------------------

.. image:: sidechain_monitor.png

When turned on, the compressor outputs side chain signal instead of main input signal.
