EAW UXA4807
8-Channel Professional Multipurpose Installation DSP Power Amplifier
The EAW UXA4807 represents a masterclass in high-density multi-zone integration, packing a colossal eight-channel power block and ultra-deep digital audio processing into a compact full-rack 2U frame. Engineered to deliver unyielding, concert-level sonic fidelity into premium commercial installations, multi-room entertainment hubs, and high-end hospitality venues, the UXA4807 provides sound contractors with an incredibly flexible, all-in-one matrix power solution. It completely eliminates rack clutter by delivering massive dynamic headroom across eight fully independent zones while retaining pristine signal transparency.
Staggering Eight-Channel Power & Hybrid-Z Elasticity
Built on industry-proven Pascal amplifier electronics, the EAW UXA4807 features an incredibly robust, agile power distribution block designed to handle a vast mix of speaker types and loads simultaneously. Driven simultaneously across all eight independent output channels, it safely unleashes a balanced 8 x 700 Watts at 2.7 ohms, 8 x 500 Watts at 4 ohms, or 8 x 250 Watts at 8 ohms.
When high-demand subwoofers or heavy theater fills require serious driving power, the channels can be smoothly configured in bridged BTL pairs to output an impressive 4 x 1400 Watts into 4 ohms or 8 ohms. Breaking away from the limits of traditional performance amplification, the UXA4807 bridges the gap into distributed commercial networks by natively driving high-impedance speaker lines—offering up to 4 x 1400 Watts for 70V systems or 4 x 1400 Watts for 100V lines via bridged BTL mode. Supported by a huge dynamic power ceiling that provides up to 5500 Watts of total peak power, this amplifier guarantees sudden transients and low-frequency impacts pass through completely free of clipping distortion.
Preloaded Greybox Loudspeaker Intelligence
The ultimate operational advantage of the EAW UXA4807 lies in its preloaded internal library of proprietary EAW Greybox™ loudspeaker profiles. Integration professionals no longer need to spend hours searching for, downloading, or manually programming complicated filter parameters. From a simple web interface dropdown, technicians can assign precise crossover boundaries, specialized FIR and IIR acoustic correction parameters, time-alignment matrices, and tailored driver protection algorithms. This ensures that every passive EAW cabinet paired with the system voices exactly as acoustically intended while remaining bulletproof against overdrive.
