The QX4-8000 is a high-performance, four-channel power amplifier engineered to deliver continuous output of 4760 watts RMS per channel into 2 Ohms. Designed for use with high-power passive loudspeaker systems, it is particularly well-suited to applications requiring sustained output and reliability under demanding operating conditions.
Encased in a compact 1U rack-mountable chassis and weighing just 12 kg, the QX4-8000 offers a high power-to-weight ratio, making it an ideal choice for both permanent installations and mobile or touring systems where space and load capacity are critical considerations.
Signal input is handled via balanced XLR connectors, ensuring compatibility with professional audio equipment and minimising noise over long cable runs. Loudspeaker outputs are provided through robust Neutrik Speakon connectors, offering secure, high-current connections suitable for low-impedance loads.
The amplifier supports multiple operational modes—stereo, parallel, and bridged—providing flexibility in system configuration. Efficient thermal management is achieved through a variable-speed, temperature-controlled fan system that ensures stable operation even under extended high-output conditions.
Comprehensive protection circuitry is integrated to safeguard both the amplifier and connected loudspeakers. This includes protection against thermal overload, short circuit, and DC offset faults. These features contribute to long-term operational reliability, even in challenging environments.
