The Amp Multi is a professional 8-channel, 4-zone amplifier designed to simplify installations while delivering high-quality audio. Its sleek, rack-ready design supports a 2U configuration, with convection cooling and GaN technology for efficient power use and minimal heat. Each of the eight 125W channels can be assigned to any zone, giving integrators complete flexibility to design multi-zone audio systems tailored to the space.
Post-filter feedback (PFFB) ensures real-time signal correction, providing precise, clear sound across a variety of speaker loads. Amp Multi includes ProTune manual controls, allowing adjustment of EQ, delay, and gain on every channel to optimize each zone's performance. The flat back and optional rack mount (sold separately) make installation fast and secure, with clear status LEDs providing immediate feedback.
Control and streaming are easy with the Sonos app, Apple AirPlay 2, or Spotify Connect. Stream up to four sources simultaneously across different zones, monitor outputs, and assign channels effortlessly using wired Ethernet or WiFi 6. Amp Multi supports Sonos Architectural speakers and offers optimization profiles for each output, giving integrators the tools to deliver precise, customized multi-zone audio experiences.
