The Ashly ne4250.70 is a 2 RU rack-mountable, network-enabled, four-channel amplifier capable of delivering 250W per channel at a constant voltage of 70V for installation in retail applications, paging systems, warehouses, and more. Its Class-D output circuitry and switched-mode power supply ensure high efficiency and reliable performance. A temperature-sensitive, variable-speed fan along with built-in amplifier and load protection inhibit overheating and overcurrent conditions.

Euroblock inputs and outputs allow standardized connectivity with line mixers and constant-voltage speakers, and the per-channel stepped, calibrated input attenuators offer easy recallability. The selectable high-pass filter can be set to 12 dB/octave at 80 Hz or 6 dB/octave at 400 Hz, thereby preventing excessive low frequencies from reaching your speakers. Setup and control of the ne4250.70 are conveniently executed via Ashly Protea software using standard 10/100 Ethernet protocol.
