Multi-Zone Audio Amplifiers8 Channels, 125W Per Channel
Amplify four rooms from one chassis. IDS CCTV supplies the Sonos Amp Multi — eight assignable outputs across four independent zones at 125W per channel, with Ethernet, Wi-Fi 6, RCA and USB-C inputs, and a rack-friendly 1.5U footprint.
What a Multi-Zone Amplifier Gives You
A multi-zone amplifier takes an audio source and delivers it to several areas of passive speakers independently. Instead of stacking single-zone amplifiers, you install one rack unit that addresses every zone over the network.
Zones & assignable outputs
Four independent zones and eight assignable outputs per chassis, so one amplifier can feed separate rooms, a stereo pair or a surround set without extra units.
Network streaming & app control
Ethernet and Wi-Fi 6 connectivity, with the Sonos app managing zones, sources and output assignments — including four simultaneous audio sources.
Inputs for local sources
RCA and USB-C inputs bring a local source into the system alongside streaming, with compatibility for Sonos subwoofers.
Rack-ready 1.5U chassis
A rack-friendly 1.5U chassis with real-time LED feedback, speaker detection and audible setup cues, plus an optional 2U Rack Mount for multi-unit racks.
