ART EQ351 Single 31-Band EQ Processor

Overview of ART EQ351 Single 31-Band EQ Processor

ART 300-Series graphic equalizers are designed for live sound, studio, and installation audio applications to provide intuitive sound shaping, versatile features, and silent operation.

The EQ351 is a single-channel 31-band EQ with a switchable range of 6 or 12 dB, for subtle shaping or dramatic sculpting of your sound. The high-pass and low-pass filters can quickly dial in the optimal bass and treble response, and the bypass control lets you compare the dry and processed signals for easy reference.

The rear panel has balanced XLR, balanced 1/4 TRS, and unbalanced RCA connectors, so the EQ351 is easy to integrate into any system. It also features a ground lift switch to help eliminate hum.
