About theAshly nXp1504 4-Channel Network Power Amplifier, 150W at 2 Ohms with Protea DSP
The Ashly nXp1504 is a four-channel network power amplifier that integrates efficient, moderate-power amplification with the advanced processing capabilities of the Protea DSP platform. Each channel delivers 150 watts into a 2-ohm load, making it well-suited for driving multiple low-impedance loudspeakers in distributed commercial audio systems such as retail stores, restaurants, and offices. This amplifier is designed for modern networked audio environments, offering not only remote control and monitoring but also the deep, customizable signal processing associated with Ashly’s flagship Protea System, enabling detailed tuning and optimization directly at the amplifier stage.A defining characteristic of the nXp1504 is its inclusion of the full Protea DSP toolkit on a per-channel basis. Accessible via network software, this processing includes parametric EQ, output delay, crossover filters, and compressor/limiters. This allows system integrators to perform precise acoustic correction, speaker alignment, and system protection for each output zone without the need for an external processor. The amplifier’s Ethernet port facilitates seamless integration into a local area network for control, monitoring, and, with optional cards, Dante audio networking. Real-time monitoring of output level, clipping, impedance, and temperature provides valuable system diagnostics from a central location.Housed in a compact 1U rack-mountable chassis, the nXp1504 is engineered for reliable, continuous operation in commercial installations. Its combination of moderate high-current power output, the powerful Protea DSP engine, and network control in a single unit makes it a highly intelligent and flexible amplification solution. The Ashly nXp1504 is ideal for system architects who require the processing depth of a dedicated DSP combined with the convenience and efficiency of a networked power amplifier for optimized multi-zone audio systems.
