CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

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

• 1 Year Warranty
