Features

  • Precision-built for professionals: Backed by thousands of hours of research and engineering, Amp Multi was built from the ground up to streamline professional installation at every stage. It’s designed to support your workflows and help you deliver bespoke audio experiences with precision and efficiency.
  • Multi-zone flexibility: Each output can be assigned to any zone, giving you complete flexibility in system design. Users can easily change audio sources and content, ensuring a seamless, consistent experience.
  • Manually tune each output: With ProTune, you can optimize the sound for the placement and room acoustics of any low-impadance passive speakers. This feature offers a comprehensive set of manual controls, including a 10-band parametric EQ and adjustable gain and delay offsets.
  • Intuitive configuration: An audible chirp identifies each unit in the Sonos app -- no PIN required. Front and rear LEDs indicate setup mode for a more seamless experience.
  • Intelligent Indicators: Speaker outputs automatically detect when a speaker is connected, while status LEDs provide real-time feedback during setup. Ambient light sensing adjusts brightness to the enviroment, and all indicators are configurable in the app.
  • Power more speakers: Select the feature Optomize Sonos Speakers in the Sonos app to unlock the ability to power up to three Sonos Architechtural speakers per output (24 total). The custom DSP optimizes the EQ, while limiter control enables even and consistent volume dynamics throughout the frequency range.
  • Flexible connectivity: Connect via wired Ethernet or WiFi 6 and stream up to four audio sorces simultaneously using the Sonos app, Apple AirPlay 2, or Spotify Connect. Analog and USB inputs provide additional flexibility, and the subwoofer output is freely assignable to any zone.
