31-Band Constant Q Graphic EQ

รายละเอียด

REQ313 31 Band Graphic Equalizer 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 REQ313. 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.   REQ313 31 Band Graphic Equalizer 31 Bands of constant Q equalization. XLR and 1/4" input and output. Low cut and High cut filters. Passive bypass.
