Sonos is a consumer electronics company based in Santa Barbara, CA founded by John MacFarlane, who previously founded Software.com. The company's main product is the Sonos Multi-Room Music System.

Multi-Room Music System

The Sonos(R) Multi-Room Music System is a modular set of digital appliances that works with end-user supplied speakers to form a zoned audio system in which different zones may play the same or different audio.

The Sonos Multi-Room Music System creates multi-room audio hi-fi in which different zones may play the same or different songs simultaneously throughout the house. The company tagline is "All the music you want. All over your house. All from the palm of your hand."

There are two main appliances in the Sonos Multi-Room Music System: ZonePlayers and Controllers. ZonePlayers may connect directly to speakers, or to an amplifier, and take the place of a traditional hifi setup. The system is controlled by the Sonos Controller, a wireless handheld remote equipped with a color LCD screen, scroll wheel and buttons that control music streaming and zone selection. Software is also available for iPhone and iPod touch, Mac, Windows computers to control the system.

ZonePlayers

ZP120 succesor to ZP100, noticeable differences include a reduced footprint, a 110 watt amplifier as well as the upgrade to SonosNet 2.0. The ZP120 has speaker posts for direct hookups to speakers and 2 Ethernet port switch on the back. Does not include audio outs as per the ZP100. Does still include Subwoofer Out.

ZP80- an Ampless ZonePlayer that includes optical out, Coaxial digital out as well as analog RCA inputs and outputs. It has a built in 2 port ethernet switch

Audio inputs with digital encoding on ZonePlayers allow for connection to external audio sources including MP3 players, Mobile Phones, CD players, TVs, DVDs, VCRs, and radios. The ZonePlayers include Ethernet jacks, and can be used as a virtual ethernet connection for normal network traffic: network traffic is bridged silently between all the ZonePlayers in a single system. This means you can stream external sources all over the house.

ZoneBridge

The ZoneBridge BR100 acts as both a first wire connection and a Wireless repeater for SonosNet.

The system is controlled by a wireless handheld remote equipped with a color 3.5” LCD screen, scroll wheel and buttons that control music streaming and zone selection, volume, play/pause, track up, track down, and back.
