Feature Controls :
The slider attached to the input meter on the left is the Threshold control. The Threshold sets the input signal level where the overall compression begins to take effect. The Threshold can be set anywhere between -60 and 0 dB.
The Frequency Range section allows you to select the specific frequency range that gets processed by the compressor. The 18 compressor bands will be distributed across whatever range is selected. For example, with Mid selected, all 18 bands will be focused on the Mid range, allowing for more precise control over the frequencies within that range.
The available Frequency Range options are as follows:
Full Range: 16 Hz – 20 kHz
High: 3 kHz – 20 kHz
High Mid: 200 Hz – 18 kHz
Mid: 180 Hz – 7 kHz
Low Mid: 12 Hz – 8 kHz
Low: 15 Hz – 500 Hz
The 6 sliders below the graph set the Depth for their corresponding bands. The 18 compressor bands are divided among the 6 sliders so that each slider controls the Depth for 3 of those bands. The range of frequencies affected are shown below each slider.
The Depth determines the maximum amount of Gain Reduction that can be applied within each slider’s control range. Possible Depth values range from -24 to 0 dB. Setting a Depth slider to 0 dB will prevent any attenuation from occurring within that slider’s control range.
The Knee value determines the hardness of compression on the input signal as it transitions through the Threshold point. Possible Knee values range from 1 to 30. With a low Knee value (Hard Knee), the compression will activate more abruptly as the signal passes over the Threshold. A high Knee value (Soft Knee) will allow the transients of the input signal to pass through more smoothly, applying compression gradually as they transition through the Threshold point.
The Output Trim adjusts the level of the compressor’s output signal anywhere from -10 dB to +10 dB. It can be used to increase or decrease the output level as needed for gain compensation.
