The Ashly nX4004 is a programmable four-channel power amplifier designed to deliver reliable, high-fidelity amplification for demanding commercial and installed sound applications. Each channel is capable of providing 400 watts into 4 ohms or 250 watts into 8 ohms, and all channels can be configured for 70V/100V constant-voltage operation, offering exceptional flexibility for driving a variety of loudspeaker loads in distributed audio systems. The amplifier's defining feature is its integration of Ashly's Protea DSP software, which provides comprehensive digital signal processing for each output channel. This includes parametric EQ, crossover filters, limiters, and delay, allowing system installers to precisely tailor the amplifier's performance to match specific loudspeaker characteristics and optimize for room acoustics, all without requiring an external processor.

Network connectivity is central to the amplifier's programmability and control, enabling seamless integration into facility IP networks for remote management and monitoring. Through a standard Ethernet connection, system administrators can access the unit via a web browser or Ashly's software to adjust parameters in real-time, monitor thermal and signal status, mute channels, and recall stored presets for different events or times of day. This remote capability, supporting protocols like Telnet and SNMP, simplifies system commissioning, routine maintenance, and troubleshooting, and allows the amplifier to be incorporated into larger third-party control systems. The design emphasizes both robust power delivery and intelligent system management, making it suitable for applications in houses of worship, performing arts centers, and corporate venues.

Built for continuous, reliable operation, the nX4004 features a robust power supply, efficient Class-H amplification technology, and a variable-speed fan for effective thermal management. Its 2U rack-mountable chassis is designed for professional installations, and the front panel provides clear status indicators and basic controls. By combining substantial multi-channel power with network-programmable DSP in a single unit, the Ashly nX4004 reduces system complexity, enhances control and diagnostics, and delivers optimized audio performance for sophisticated fixed-installation sound reinforcement.
