Electro-Voice Q66II: High-Power Pro Music Amplifier with Legendary LPN Bass Enhancement

The Electro-Voice Q66II is a professional-grade power amplifier within the prestigious Q-Series, engineered to deliver the high-output performance and rugged durability that defines the EV brand. Specifically designed for Pro Music and diverse sound reinforcement applications, the Q66II provides a solid 600 Watts per channel at 4 Ohms and peaks at 900 Watts at 2 Ohms. This makes it an exceptionally flexible power source for a wide array of passive speakers, including the Sx300, ZX4, and SB122. Built on a Class-AB topology, it retains the classic EV sonic character while offering substantial dynamic headroom to handle the unpredictable peaks of live musical performances with ease.

Key Features

• Patented LPN (Low-Pass Notch) Filter: A switchable sonic enhancement that adds depth and punch to the low-end frequencies, featuring integrated low-cut protection to optimize 12-inch or 15-inch cabinets when operating without a subwoofer.
• Proven Class-AB Design: Delivers the high-fidelity sound and linear performance of traditional Class-AB amplification, ensuring clean audio reproduction and low harmonic distortion.
• Massive Dynamic Headroom: Tailored for real-world live sound demands, providing the necessary power reserves to handle transients without loss of audio quality or stability.
• Simplified Bi-Amp Connectivity: The Output A NL4 connector is wired to carry Output B signals on pins +/- 2, facilitating clean and efficient cabling for bi-amplified speaker systems.
• Integrated Dynamic Limiter: Built-in circuitry that monitors and controls signal peaks to prevent clipping, protecting both the amplifier and your loudspeakers from damage during high-output operation.
• Advanced Cooling & Protection: Equipped with a comprehensive protection suite and a 3-stage front-to-rear cooling fan system to ensure reliable operation in demanding thermal environments.
