RDL RU-EQ3 Three Band Equalizer with Knobs - Terminals

The RU-EQ3 is designed with a versatile bridging input that allows for both balanced and unbalanced connections. Its output driver boasts a 150 Ω balanced impedance and is engineered to drive unbalanced or balanced lines with an impedance of 150 Ω or higher. The active equalization knobs on the front panel are specially curated to cater to a broad range of systems and are dedicated to separate audio bands. These knobs provide a boost or attenuation of at least 12 dB to each band's center frequency. The low and high band equalizers are thoughtfully designed to function as a total bass or treble control, with a carefully selected Q value. The RU-EQ3 also comes with a midrange control, precisely optimized for voice band adjustment, and calibrated for smooth operation in wideband music applications. The module is equipped with an OVERLOAD indicator that flashes if either the input or output stage clips.
