Description
The Electro-Voice Q44 Power Amplifier is a robust two-channel amplifier delivering 2 × 650W @ 2Ω / 2 x 450W @ 4Ω / 2 × 270W @ 8Ω, designed for professional audio environments where efficiency and reliability are essential. It provides clean and consistent power for small to medium passive loudspeaker systems, making it well suited for live sound reinforcement, permanent installations, and rental applications. Although this model has been discontinued by the manufacturer, it is still available at Rauf Electronics.
Featuring switchable LPN (Low-Pass Notch) filtering along with a built-in low-cut protection circuit, the Q44 improves low-frequency definition while protecting compact 12″ and 15″ loudspeakers. This smart signal processing ensures controlled bass performance and dependable operation, even in systems operating without dedicated subwoofers.
