INTRODUCTION
The ROLLS REQ313 graphic equalizer is intended for 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.
