Description
The Electro-Voice Q66 Power Amplifier is a versatile two-channel amplifier delivering 2 × 900W @ 2Ω / 2 x 500W @ 4Ω / 2 × 380W @ 8Ω, designed for professional audio applications that require dependable and efficient power delivery. It offers stable performance for medium-sized passive loudspeaker systems and is well suited for live sound reinforcement, fixed installations, and rental environments where consistent output and reliability are essential.
Equipped with switchable LPN (Low-Pass Notch) filtering and an integrated low-cut protection circuit, the Q66 improves low-frequency definition while helping protect 12″ and 15″ passive loudspeakers. This intelligent signal processing ensures controlled bass response and enhanced system stability, even in setups operating without dedicated subwoofers. Although this model has been discontinued by the manufacturer, it is still available at Rauf Electronics.
