Rolls REQ131 Single Channel 31 Band Graphic Equalizer with High and Low Pass Filters

The REQ131 from Rolls is a single channel, 31-band graphic equalizer that is a useful signal processing tool where precise frequency control is needed across the audio spectrum. Designed for sound reinforcement and recording applications, the smooth band-pass filtering and transparent low-noise circuitry provide virtually distortion free operation.

Since the frequency band centers are ISO standard, the unit is compatible with most real time analyzers. When used with an analyzer, the REQ131 may be used to tune an acoustical environment to avoid feedback, increase clarity and flatten the overall frequency response of an acoustical environment.
