Ashly Audio's NE Series amplifiers are network-enabled, multi-channel power amplifiers with a Class-D platform and switching power supply. The series includes the ne4250 (4-channel) and ne8250 (8-channel) models, each rated at 250W per channel. Features include 10/100 Ethernet for remote control and monitoring, FIR filter capability, low-Z, 25V, 70V, and 100V models, and optional AES3 inputs, mic pre inputs, CobraNet, and Dante modules. The amplifiers have a 5-year warranty and are safety/compliance certified with cTUVus, CE, FCC, and RoHS.
