A pair of integrators and MIT engineers present the Netonos Note, a means to integrate Sonos multi-room audio systems with doorbells and surround sound receivers, allowing the playback of whole-house announcements.
The Note stacks on top of Sonos Connect Network controller, and supplies automated control of surround receiver power on and off, source selection and volume control, eliminating the need for multiple remotes.
It is compatible with most AV receivers, including Denon, Marantz and Yamaha, via ethernet, RS-232, IR or 12V trigger.
