Cut-Only Equalizer

Term used to describe graphic equalizers designed only for attenuation (also referred to as notch equalizers, or band-reject equalizers). The flat (0 dB) position locates all sliders at the top of the front panel. The filters (normally spaced at 1/3-octave intervals) all start at 0 dB and reduce the signal on a band-by-band basis. Proponents of cut-only philosophy argue that boosting runs the risk of reducing system headroom. Historically many cut-only EQ’s have been passive devices, which in some audiophile circles means they have the potential to sound better (no op amps = less distortion and noise).
