Crestron DM-NAX-4ZSA-50 – DM NAX 4+1 Zone Streaming Amplifier

Product Overview

The Crestron DM-NAX-4ZSA-50 is a next-generation DM NAX Audio-over-IP 4+1 zone streaming amplifier, providing four independent amplified audio zones plus one subwoofer or auxiliary output in a single rack-mount chassis. It receives DM NAX Audio-over-IP streams from the Gigabit Ethernet network — from DM NAX encoders, streaming sources, and DM NAX preamplifiers — and delivers amplified audio to four independent speaker zones simultaneously, each carrying independent source selection and volume control from Crestron 4-Series control systems and touch panels.

Product Description

The DM-NAX-4ZSA-50 replaces traditional analog zone amplifiers with a networked audio streaming approach — audio sources are distributed over the Gigabit Ethernet network as DM NAX streams rather than as analog audio cable runs from a central DSP or preamplifier to each amplifier. This architecture enables flexible source routing without signal level audio cabling between rack components: any DM NAX source on the network can be routed to any zone of the DM-NAX-4ZSA-50 in real time from the 4-Series control system. The 50W per channel output is suited for standard commercial speaker loads in conference rooms, lobbies, and open-plan office audio zones, and the 5th output channel provides a dedicated subwoofer or additional auxiliary output for full-range commercial audio installations.

Key Features
