Shown below are the Custom Preset sub-tab parametric controls corresponding to A thru H on the previous page. Non-standard
controls and unique functions are described below.
• Parametric EQ 1 thru 3 : Provides 3 bands to provide notch filters. Default set to 0 dB (no effect). Each filter has a ±12 dB
gain control, and selectable center frequencies from 20 Hz – 22.05 kHz.
• Inf :>1Thr check boxes: When enabled, automatically increases AGC ratio to Infinity:1 once a signal exceeds the AGC
threshold, allowing for expansion below the threshold and limiting above the threshold. Useful for bass frequency control.
• Soft Clip controls : For low-frequency bands 1 and 2, sets the point above in which band 1 (low bass) and band 2 (mid bass)
are very quickly limited, acting more like a clipper without the artifacts. This helps maintain a “tight” bass sound.
