Connecting and controlling an amplifier for networked systems has now been simplified with Network-Enabled Amplifiers. This line offers ease of use, setup and control using standard 10/100 Ethernet protocol and Protea™ ne Software. No special outboard control units are needed. Choose either 4-channel ne4250 or 8-channel ne8250 amplifiers are rated at 250W per channel with separate HI-Z and LO-Z models. ne Series amplifiers are offered in two separate platforms—the standard network amplifier or a network amplifier with an on-board Protea™ DSP Processor. Each can be customized for any installation by adding your choice of AES3 inputs, Dante™ or CobraNet™ card. NE Multi-Channel amplifiers are also offered with 240V Line Voltage in either Low-Z or 100V constant voltage output models for International customers.
