About theAshly PEMA 8250.70 8-channel Network Power Amp
The Ashly PEMA 8250.70 is a high-density, eight-channel network power amplifier specifically engineered for large-scale commercial distributed audio systems. Each channel is configured to deliver power into 70V (and typically 100V) constant-voltage speaker lines, making it an all-in-one solution for powering extensive background music and paging networks in venues like shopping malls, airports, hotels, and educational campuses. This networked amplifier integrates eight channels of efficient Class D amplification into a single 2U chassis, providing exceptional power density and simplifying installation by eliminating the need for external output transformers. Remote control, configuration, and monitoring are enabled via Ethernet, allowing for centralized management of the entire amplification system from a computer.The amplifier includes onboard digital signal processing for each output channel, accessible through network software. This integrated DSP provides essential tools like parametric EQ, output delay, and limiting, enabling system integrators to optimize and protect each zone directly from the amplifier without needing an external processor. Remote management capabilities allow technicians to adjust levels, configure DSP settings, and monitor system status—such as output level, clipping, and temperature—facilitating easy maintenance and optimization. The amplifier is built for reliability in 24/7 operation with comprehensive protection against faults.By combining high-channel-count constant-voltage amplification, networked intelligence, and per-channel DSP, the PEMA 8250.70 represents a highly efficient and scalable solution. It is designed for system architects who need to power and manage extensive multi-zone audio systems with centralized control and processing, dramatically reducing rack space and system complexity.
