Studiomaster nEX2-1000 AES67 Networked 2-Channel Power Amplifier

Studiomaster nEX2-1000 AES67 Networked 2-Channel Power Amplifier

The Studiomaster nEX2-1000 AES67 networked 2-channel power amplifier delivers 500W per channel at 8 ohms, 750W per channel at 4 ohms, or 1500W bridged at 8 ohms. Its Class-D design combines high-output amplification, onboard DSP, network audio transport, and a compact 1U rack enclosure for fixed professional sound systems.

Designed for installed audio, houses of worship, performance venues, education facilities, and commercial AV systems, this networked amplifier supports stereo, parallel mono, and bridged operation. Balanced combination inputs and professional speaker outputs simplify integration, while dual Ethernet ports connect the amplifier to AES67 audio-over-IP networks for low-latency routing, monitoring, and control.

A front-panel 1.8-inch TFT display provides access to levels, presets, operating temperature, protection status, and network information. Built-in processing includes equalization, filtering, delay, dynamics, feedback suppression, matrix mixing, and gain sharing. Front-to-rear forced-air cooling, a removable dust filter, and multiple protection circuits support dependable rack-based operation.
