The Ashly nXp Series nXP4004 is a high-power, intelligent four-channel network amplifier that combines substantial output capability with the advanced configurability of the Protea Software Suite. Each channel delivers 400 watts of efficient Class D amplification, suitable for driving demanding loudspeaker loads in professional installed sound applications. A defining feature of this amplifier is its programmable output configuration, allowing each channel to be software-defined for specific operating modes, including low-impedance, 70V, or 100V operation, eliminating the need for physical jumpers or switches and enabling complete setup and adjustment from a networked computer.

The integration of the Protea Software Suite elevates this amplifier beyond a simple power source, providing deep, per-channel digital signal processing directly within the unit. Accessible via Ethernet, the DSP includes parametric EQ, output delay, crossover filters, and compressor/limiters. This allows system integrators to perform detailed acoustic tuning, speaker optimization, and system protection without requiring an external processor. The software provides a graphical interface for intuitive system design, real-time monitoring of parameters like output level, temperature, and impedance, and the storage of multiple presets for different operating scenarios.

Housed in a 2U rack-mountable chassis designed for optimal thermal management, the nXP4004 is built for reliable 24/7 operation in demanding commercial environments. Its combination of high power density, programmable outputs, extensive Protea DSP, and network control makes it a highly flexible and intelligent amplification platform. The Ashly nXP4004 is engineered for system architects who require a future-proof, software-configurable amplifier that can serve as the cornerstone of a sophisticated, networked audio ecosystem.
