On the main panel, tuning and control parameters are accessible as follows:
- InputGain: Controls stereo input gain. This can be used to apply gain to stereo input signal.
- CrossOver: Speaker cutoff frequency. This tuning parameter is used to set the speaker cutoff frequency below which speaker is unable to reproduce the sound. Harmonics are generated for each frequency component below speaker cutoff frequency.
- Dist odd: Odd harmonics level control. The harmonics generated will have odd and even harmonic components. This tuning parameter is used to control the level of odd harmonics.
- Dist even: Even harmonics level control. This tuning parameter is used to control the level of odd harmonics.
- Threshold: Limit level of harmonics. This compressor tuning parameter is used to limit level of harmonics generated. When signal level reaches this values compression is activated.
- Attack: Attack time constant. This time constant determines amount of time required to compress the signal to target value.
- Release: Release time constant. This time constant determines amount of time required to restore the signal to its original value once signal level drops below Threshold.
- Ratio: Amount of the Compression applied to harmonic signal when harmonic signal level exceeds Threshold
- Delay Left ch: Delay control for high pass filtered left channel. This control is used to delay Left channel to time align with harmonic signal
- Delay Right ch: Delay control for high pass filtered right channel. This control is used to delay Right channel to time align with harmonic signal
- Harmonic Gain: Control harmonic output level. This control is used to adjust the output level of harmonic signal.
- Presets: Different tuning sets and Bypass. Tuning sets have values for Low, Moderate and Strong bass generation. Preset also has tuning to bypass(bass off).
- Biquad: Biquad panel to shape the harmonics. The biquads can be tuned to shape harmonics.
- Mixer: Panel to control the mixer gains.
