Stereo universal frequency equalizer with fine f-specific control by adjusting center frequency and resonance peak.
The left and right audio bands are divided into five bands.
The frequency control can vary continuously from the center frequency of each band to within ± 1.6 octaves of the reference center frequency.
The BANDWITHCON and R-L can freely change the sharpness of peaks and dips, and can make subtle corrections of less than 1/4 octave width.
The sliding volume band level control allows you to change the level of each band continuously within ± 12 dB at the center frequency. When all the sliding volumes are set to the midpoint, the characteristic is + 0 -0.2 dB from 10 Hz to 20 kHz with little distortion.
