DBX 555 5-Band Parametric Equalizer for 500 Series Module

500 Series 5-channel parametric equalizer with controls for level, frequency, bandwidth, bypass and on/off. Each of the 555's bands offer the typical gain, frequency center and bandwidth controls and operate as peaking (bell) type filters. Gain can be adjusted by up to +12dB of boost or -15dB of cut. Bandwidth is continuously variable between .03 and 2.0 octaves. Each band also has an on/off switch, making it easy to compare each band's affect against the original, unprocessed signal. And if you decide against using a band, simply leave the band off to easily remove it from the signal path - rather than having to "zero out" the controls.
