The FPâ€‘PEQ3 is the ideal choice in many applications where parametric equalization or acoustic notch filtering is needed. The FPâ€‘PEQ3 is a singleâ€‘channel module featuring three identical independent filters. Each filter has separately adjustable FREQUENCY, BOOST/CUT amplitude, and bandwidth (BW) parameters. The FREQUENCY has three fully overlapping switchâ€‘selectable ranges: 15 Hz to 200 Hz, 150 Hz to 2 kHz, 1.5 kHz to 20 kHz. The BOOST/CUT provides a Â±15 dB range, switchâ€‘selectable to produce either cut or boost, making acoustic adjustment easier than with other parametric equalizers. Setting a given filterâ€™s BOOST/CUT to minimum completely removes that filter from the circuit. The bandwidth (BW) allows adjustment from 0.04 octave to 1.5 octave.
