7.4.2 Parametric Equalizer
Bandwidth: That is, the range of influence of the segment around the center frequency, the
larger the value, the greater the bandwidth and the greater the range of influence.
Equalizer type: 5-terminal parametric equalizer
Passthrough/Enable: enable/disable the equalizer;
Band Pass/Enable: Enable/disable the equalizer for the current band
Reset: restore the current parameters to the default state
Center frequency: the center frequency that needs to be equalized
Gain: the gain/attenuation value of the frequency center point
Dante 4-Channel Audio DSP
Parametric equalizers are digital filters used in audio for adjusting the frequency content of a
sound signal. Parametric equalizers provide capabilities beyond those of graphic equalizers
by allowing the adjustment of gain, center frequency, and bandwidth of each filter.

Enable: Compressor enable indicator or control
Threshold: Threshold of the compressor.
Ratio: The input and output compression ratio of the compressor.
Attack Time: The start time of the compressor.
Recovery Time: The recovery time of the compressor.
Reset: reset to default parameters
Compressors are used to reduce the dynamic range of signals above a user-determined
threshold, the signal levels below the threshold remain unchanged.
