About the Rolls REQ215

The REQ215 from Rolls is a dual channel, 15-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.

Rolls REQ215 Features

  • Dual channel, 15-band graphic EQ in a one space, rack-mount chassis
  • High and low pass shelving filters
  • XLR and 1/4" balanced and RCA inputs and outputs
  • Passive bypass for making accurate comparison of source and processed audio
