Connector panel


Ethernet ports (2)

Use an Ethernet cable if you want to connect to a router, computer, or network-attached storage (NAS) device (optional).

AC power (mains) input

Use only the supplied power cord (using a third-party power cord will void your warranty).

Note:Be sure to use the proper power adapter for your country.

Select a location

If you purchased a Boost to replace a Sonos product that’s connected to your router, first add the Boost to your Sonos system, then plug it into your router and move the one that was originally wired.

If you purchased a Boost to extend the range of your Sonos system, place the Boost in between the Sonos speaker that’s out of reach and the rest of the Sonos system.

Wall mounting

  1. Choose a location that’s close to an electrical outlet (power cord length is 6 ft. / 1.8m), away from heat sources, hidden wiring, gas lines, etc.

  2. Drive an American standard #6 round head screw (metric, M3.5 round head screw) into the wall, leaving a gap between the wall and the screw head (approximately 0.13 in / 3.3mm).

  3. Note:Pan head screws will also work.

  4. Place the Boost on the wall and slide straight down, allowing the screw head to slip behind the smaller end of the keyhole slot on the back of the Boost.
