QXD-1K
4-Channel 1000W Power Amplifier with DSP and Network CapabilityThe QXD-1K is a compact 1RU, 4 x 250W Class-D amplifier designed for professional audio-visual environments. It offers flexible bridged output options up to 2 x 500W, including 70V/100V capabilities. This amplifier features UMAC™ Class-D technology, ensuring ultra-low distortion, high efficiency, and low power consumption. It’s ideal for fixed installations and includes a 32bit/96kHz DSP with FIR/IIR filters, peak and RMS limiters, and Quest speaker libraries.
A front-panel TFT display, RJ45 (network port), and GPIO provide intuitive local and remote control and monitoring capabilities. The RJ45 port allows for seamless integration into larger site-wide DSP and control systems, such as Q-Sys or Crestron, enabling comprehensive remote monitoring of the amplifier.
With advanced protection features, fan-forced cooling, universal mains, and a standby power consumption of under 0.5W, the QXD-1K is a robust and network-ready amplifier. Dante® Version Available – QXD-1KD (additional 4 inputs, Dante® AoIP, AES67 compatible)
