The capability of the highly popular Sonos wireless music system is set to be expanded with the introduction of new extenders.

Sonos is expanding their wireless mesh-network multiroom music system by launching a dedicated low-cost wireless extender and expanding the number of premium subscription-music services that can be distributed throughout a broadband-connected home without turning on a networked PC.

Sonos’ system, launched in 2005, consists of a  wireless-RF LCD remote that displays the song library of a networked PC, displays a menu of Web-based streaming sites accessible without a networked PC, and directs music to wireless clients called ZonePlayers. The clients incorporate audio decoders, DACs and proprietary wireless mesh-network technology to access PC-stored songs and Internet music without long wire runs.

A Zone Player incorporates a 2 x 50-watt amp to drive passive speakers, and a version without amplifiers connects to Legacy stereo systems.


To distribute music wirelessly, consumers previously had to use an Ethernet cable to connect one of these ZonePlayers to a nearby networked router. With the launch of the ZoneBridge, however, consumers can make the wired connection to a router at a lower cost. As a result, ZoneBridge makes Sonos systems more practical for use in newer homes whose network routers are installed in structured-wiring cabinets in utility closets where no one listens to music, said Sonos president Phil Abram.

ZoneBridge also makes Sonos more practical in houses where a PC and router are in close proximity — in these applications, consumers often don’t need an expensive Zone Player near their PC, which can easily be used instead of a Zone Player for music playback, he said.

The 10.9 centimetre by 10.9 centimetre by 4.06 centimetre ZoneBridge also doubles as a repeater that can be used in lieu of a more costly ZonePlayer to extend system range in large houses, Abram said. The range of a ZonePlayer or ZoneBridge is about 1524 centimetre to 45 metres depending on the house.

Custom installers can use the ZoneBridge to extend the range of the Sonos wireless remote in large homes, he added. In a custom application, installers mount multiple ZonePlayers in a central A/V rack and wire them to in-wall and in-ceiling speakers spread throughout the house. In some cases, installers connect the Zone Players directly to more powerful multiroom amplifiers or to a custom-installation hub that connects to other centrally located A/V sources. In a custom application, Sonos’ remote is needed to control music selection because in-wall touchscreens can’t display the Sonos menu, Abrams noted.


ZoneBridge “also helps us at retail” because dealers can use less expensive ZoneBridges to extend system range to demo units in a store, he said.

With or without a ZoneBridge, a Sonos system now accesses five premium subscription-streaming services direct via networked broadband modem without a PC or networked-attached storage (NAS) device running. Sonos added direct access to the Napster and Best Buy on-demand subscription-streaming services, which join already-available direct access to the Rhapsody on-demand service and the Sirius and Pandora radio services, Abrams said.

Combined with direct access to 400 non-subscription Internet radio stations, he said, Sonos is expanding its appeal beyond digital music enthusiasts who rip CDs for storage on a home PC.

“It has become easy to find music through the giant jukebox in the sky without having to buy and rip CDs,” Abram said.
