SKU QXD5K
QXD-5K
4-Channel 5000W Power Amplifier with DSP and Network Capability
The QXD-5K is a high-powered, 2RU, 4 x 1250W Class-D amplifier designed for performance-critical installations. It delivers up to 2500W per channel in bridged mode and supports 70V/100V operation. Built on UMAC™ Class-D architecture, this amplifier offers exceptional dynamic range, ultra-low distortion, and highly efficient power delivery. It includes an integrated 32bit/96kHz DSP for precise signal management, featuring FIR and IIR filters, peak and RMS limiters, and onboard Quest speaker presets.
For control, a high-resolution TFT display and LED-illuminated encoder are available on the front panel. Network control and GPIO are accessible via the RJ45 port, allowing for remote management and integration into broader AV systems.
The amplifier features Neutrik speakON® outputs and powerCON® mains connections for professional-grade reliability. Dante® Version Available – QXD-5KD (additional 4 inputs, Dante® AoIP, AES67 compatible)
