REQ313 GR APHIC EQUALIZER
The ROLLS REQ313 graphic equalizer is intended for room equalizing or sound shaping and the approximate fre-
quency response curve can be seen graphically by the settings of the frequency controls. Recording and broadcasting
studios, sound contractors and musicians will appreciate the low noise, straightforward design, and versatile signal
control of the REQ series.
The equalization filters in the REQ313 are constant bandwidth
(constant Q).The bandwidth of each individual filter is narrow
enough to prevent unwarranted interaction between filters, yet
wide enough to produce exactly the type of correction curve
demanded by even the most unusual acoustic surroundings.
FEATURES
• 31 Bands of constant Q equalization
• XLR and 1/4” input and output
• Low cut and High cut filters
• Passive bypass
• 1Year Warranty
