GX3, GX5, GX7 specifications

QSC Audio has established itself as a leader in professional audio solutions, and its GX series of power amplifiers—GX7, GX5, and GX3—reflect the brand's commitment to quality and performance. These amplifiers are designed to deliver reliable, high-quality sound reinforcement, meeting the demands of musicians, DJs, and audio engineers alike.

The QSC GX7 is a robust amplifier capable of delivering 1,000 watts per channel at 4 ohms, making it an excellent choice for larger venues or events where powerful sound output is essential. It features QSC's PowerLight technology, which provides high efficiency and a lightweight design, ensuring portability without sacrificing power. The GX7 also includes an advanced clip limiter that protects the system from distortion, while maintaining audio clarity. Its rear panel features XLR and TRS inputs, allowing for versatile connectivity options.

Next in the lineup is the GX5, a mid-range amplifier that offers 700 watts per channel at 4 ohms. It strikes a perfect balance between performance and size, making it suitable for both small to medium-sized events or as part of a larger sound system. Like the GX7, it adopts the PowerLight technology for energy efficiency, and its durable construction ensures reliability in diverse environments. The GX5 also comes equipped with a low-frequency protection circuit that safeguards speakers from over-excursion, preserving sound quality throughout usage.

The smallest of the series, the GX3, delivers 500 watts per channel at 4 ohms. Ideal for smaller venues, mobile applications, or as monitors in a studio setting, the GX3 shares many of the same technologies as its larger counterparts, including the PowerLight design and a comprehensive protection system. Its front-to-back ventilation helps maintain thermal stability, enhancing performance during longer sessions.

All three models incorporate a design philosophy emphasizing user convenience and flexibility. The amplifiers feature an intuitive rear panel layout that simplifies setup and operation, while their lightweight design makes them easy to transport. QSC’s innovative technology ensures consistent performance and durability, making the GX series a trusted choice for professionals.

In summary, the QSC Audio GX7, GX5, and GX3 amplifiers deliver impressive power, solid build quality, and advanced features tailored for a variety of audio applications. Whether powering large PA systems or small setups, these amplifiers embody QSC's dedication to audio excellence and reliability.
