Ashly ne4250.70BD 4-Channel Amplifier with OPDante and OPDAC4 Option Cards

$2,699.00

The ne4250.70BD is built on an energy-efficient Class-D platform with a switching power supply for reliable and energy-conscious performance. It comes with a factory-installed OPDante network audio input card and an OPDAC4 digital-to-analog converter card, which simplifies installation and wiring for networked audio systems. All configuration, control, and monitoring are handled remotely via a standard 10/100 Ethernet connection and Ashly's Protea NE Software. This model allows for versatile output options, including the ability to bridge channels for higher power output (500W at 140V). It features software-controlled high-pass filters and supports various remote control functions via contact closures or DC voltage. The amplifier is housed in a rugged 2RU, rack-mountable chassis with Euroblock connectors for secure and reliable audio inputs and outputs.

About the Ashly ne4250.70BD 4-Channel Amplifier with OPDante and OPDAC4 Option Cards

The Ashly ne4250.70BD is a fully loaded, network-centric four-channel amplifier designed as a comprehensive audio endpoint for sophisticated installed systems. This model is distinguished by its inclusion of two critical option cards: an OPDante card for Dante Audio over IP connectivity and an OPDAC4 card providing four channels of analog-to-digital conversion. This configuration allows the amplifier to accept audio from both digital Dante networks and traditional analog sources simultaneously, offering maximum input flexibility for hybrid systems. It is specifically engineered to drive 70V and 100V constant-voltage speaker lines directly, making it a powerful all-in-one solution for large-scale commercial background music, paging, and multi-zone audio distribution.

The integration of the OPDante card transforms the amplifier into a native device on a Dante network, capable of receiving multi-channel digital audio streams over Ethernet. The OPDAC4 card complements this by providing four balanced analog inputs, ensuring compatibility with legacy or non-networked sources. Onboard DSP is fully accessible for all four output channels, allowing for individual parametric EQ, delay, crossover, and limiting to be applied, regardless of the input source. This level of processing enables precise tuning and protection for each speaker zone directly within the amplifier, reducing the need for external signal processors and simplifying system architecture.

Built for continuous duty in demanding environments, the ne4250.70BD features robust protection circuitry and efficient Class D amplification in a 1U rack-mountable chassis. Remote monitoring and control of all parameters—including input selection, DSP settings, output levels, and system diagnostics—are available via network software. By combining dual-format audio inputs, constant-voltage outputs, and extensive DSP in a single, network-manageable unit, the Ashly ne4250.70BD represents a highly integrated and future-proof solution for complex, professional audio installations.
