The REQ313 from Rolls is a single channel, 31-band graphic equalizer designed for room equalization or audio material sound shaping. Recording and broadcasting studios, sound contractors and musicians will appreciate the low noise, straightforward design and versatile signal control of the unit.
The approximate frequency response of the equalizer can be seen graphically by the positions of the frequency controls. The filters in the unit are constant bandwidth with the bandwidth of each individual filter being narrow enough to prevent unwarranted interaction between filters, yet wide enough to produce exactly the necessary correction curve demanded by the acoustic surroundings.
