Overview

ne4250.70 amplifier plus OPDante and OPDAC4 Option Cards

OPDante: Option Card (Dante Network Audio Interface)
OPDAC4: Option Card (Internal 4-Channel DAC - Digital to Analog Converter) with Selectable HPF

These NE 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 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, mic pre inputs* or a 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.
