REQ315 GR APHIC EQUALIZER

The ROLLS REQ315 graphic equalizer is intended f or room
equalizing or sound shaping and the approximate frequency
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 REQ315 are constant bandwidth
(constant Q). The bandwidth of each individual filter is narrow
enough to prevent unw arranted inter action between filters, y et
wide enough to produce exactly the type of correction curve
demanded by ev en the most unusual acoustic surroundings.

FEATURES

• Two channels with 15 bands of constant Q equalization each

• XLR and 1/4” inputs and outputs

• Low cut filters

• 6/12 dB Boost/Cut Range switch

• Passiv e b ypass

• 1 Year Warr anty
