QXD-10K
4-Channel 10000W Power Amplifier with DSP and Network CapabilityThe QXD-10K is a flagship 2RU, 4 x 2500W Class-D amplifier designed for the most demanding installed sound applications. It delivers exceptionally high output with refined efficiency and ultra-low distortion, supporting 8Ω, 4Ω, 70V, and 100V operation, and providing up to 10,000W total continuous power. Leveraging UMAC™ Class-D technology, the QXD-10K integrates a 32bit/96kHz DSP for advanced signal processing. This includes FIR/IIR filters, peak and RMS limiters, and Quest’s proprietary speaker tuning libraries.
A front-mounted high-resolution TFT display with an LED encoder allows for intuitive configuration. System-wide control and monitoring are supported by RJ45 (network port) and GPIO connectivity, enabling seamless integration into larger control systems.
Equipped with Neutrik speakON® outputs and a powerCON® mains input, the QXD-10K ensures secure connections in high-power environments. Dante® Version Available – QXD-10KD (additional 4 inputs, Dante® AoIP, AES67 compatible)
