The dbx 555 parametric EQ is comprised of five separate EQ bands that can be switched on and off independently. Each of this equalizer’s bands also employs a Bandwidth knob to dictate how wide an area it effects. A global Bypass switch makes comparing processed and unprocessed signals a breeze. An LED display supplies proper metering and LME49720 op-amps yield top-notch sound quality. The dbx 555 5-band parametric EQ puts an excellent sound-shaping tool in your 500 Series rack!
