EQ355
Dual 31-Band Graphic EQ
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 EQ355 is a dual-channel EQ with 31 bands per channel. Each channel has an independently switchable range of 6 or 12 dB, variable high-pass and low-pass filters, master level control, and bypass switch to quickly compare the dry and processed signals.
The rear panel has balanced XLR, balanced 1/4 TRS, and unbalanced RCA connectors, so the EQ355 is easy to integrate into any system. It also features a ground lift switch to help eliminate hum.
