Description
The Electro-Voice Q99 Power Amplifier is a high-performance two-channel amplifier delivering 2 × 1250W @ 2Ω / 2 x 900W @ 4Ω / 2 × 550W @ 8Ω, designed for professional audio applications, offering strong and stable power output to confidently run medium to large passive loudspeaker systems. Built with EV’s proven reliability, it is suitable for live sound, fixed installations, and rental use where consistent performance is required.
Equipped with switchable LPN (Low-Pass Notch) filtering and an integrated low-cut protection circuit, the Q99 enhances low-frequency clarity while safeguarding smaller 12″ and 15″ cabinets. This intelligent processing allows tighter bass response and improved system control, even in setups where no separate subwoofer is used. Although this model has been discontinued by the manufacturer, it is still available at Rauf Electronics.
