Used ART 351 Dual 31-Band Graphic Equalizer Rackmount EQ

ART 351 designed as a professional dual-channel 31-band graphic equalizer built for live sound, studio, installed audio, and PA system tuning applications. Featuring standard 1/3-octave frequency spacing across the audible spectrum, the unit allows precise adjustment of problem frequencies for feedback control, room correction, monitor tuning, and overall tonal shaping.

The ART 351 typically includes independent left and right channel EQ sections, switchable range settings, balanced XLR and TRS connectivity, high-pass filtering, clip indicators, and bypass functions for flexible integration into live and recording environments. Graphic EQs like the 351 are widely used in FOH systems, monitor rigs, rehearsal spaces, DJ setups, and studio patchbays because they provide fast visual control over frequency response and system tuning.

Known for rugged rackmount construction and straightforward analog operation, the ART 351 became a practical affordable option for engineers, musicians, venues, and mobile sound companies needing reliable frequency control without moving into higher-end touring-grade processors. A versatile rack EQ ideal for PA optimization, monitor feedback reduction, live sound shaping, and studio signal processing applications.
