About the Ashly ne4250.70peD 4-Channel Amplifier with OPDante Option Card
The Ashly ne4250.70peD is a sophisticated four-channel network power amplifier specifically engineered for large-scale commercial distributed audio systems. A key feature is its built-in capability to directly drive 70V and 100V constant-voltage speaker lines, making it an ideal, all-in-one solution for background music and paging applications in venues like shopping malls, airports, hotels, and educational campuses. Each of its four channels is powered by a high-efficiency Class D amplifier, delivering substantial and clean power to long speaker runs without the need for external transformers. This integrated design simplifies installation, reduces points of failure, and provides precise per-channel control over the voltage and power delivered to each zone.
This amplifier is defined by its intelligent network integration, coming equipped with an OPDante option card slot. This allows for native connectivity to a Dante Audio over IP network, enabling the amplifier to receive digital audio streams for all four channels directly via a standard Ethernet cable. This convergence of power amplification and networked audio transport facilitates flexible, scalable system designs where audio can be routed from any Dante source on the network. Furthermore, the amplifier includes onboard DSP for each channel, configurable via network software, providing essential zone-specific processing like parametric EQ, output delay, and protective limiting directly at the amplification point.
Built for reliability in 24/7 operation, the ne4250.70peD includes comprehensive protection circuitry for each channel, guarding against thermal overload, short circuits, and other faults. Its compact 1U chassis saves valuable rack space while housing the powerful amp modules, network audio card interface, and DSP engine. Remote monitoring of parameters such as output level, clipping status, and temperature is available through Ashly's network software. By combining constant-voltage outputs, Dante readiness, and per-channel DSP in a single unit, this amplifier represents a modern, centralized, and intelligent solution for powering and managing extensive commercial sound systems.
