Description
NE Series Multi-Channel, Network-Enabled Power Amplifiers
Our multi-channel ne (Networked-Enabled) Series Amplifiers are uniquely designed around an energy efficient Class-D platform with a switching power supply.
Connecting and controlling an amplifier for networked systems has now been simplified with ne 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 the ne4250 (4-channel) or ne8250(8-channel) packages rated at 250W per channel, with separate Hi-Z and Low-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, mic pre inputs, CobraNet or Dante modules.
