It uses a variant of the TK2050 to provide 50 watts per channel of high-efficiency, high-fidelity power for the ZonePlayer's speaker outputs. The Sonos(TM) Digital Music System is comprised of two stylish components: the Sonos ZonePlayer, a networked audio player that distributes, plays and amplifies music in any "zone" in the home, and the Sonos(TM) Controller, a wireless handheld device with a full-color screen which allows the user to access, customize and control the music anywhere -- from the bedroom to the backyard. Class-T amplifiers allow the ZonePlayer to provide ample, high quality power to stereo speakers, without generating excess heat. The ZonePlayer offers lots of features packed into a small and stylish case. The TK2050, with an efficiency of 92%, allows the unit to operate without a cooling fan. A typical class AB amplifier See amplifier classes. would dissipate nine times as much heat as the Class-T design in normal operation, prohibiting the cool and quite operation of the Sonos system. Standard class-D amplifiers would not be able to offer the audio fidelity that Sonos required for the ZonePlayer (0.02%THD ThD abbr. Latin Theologiae Doctor (Doctor of Theology) Noun 1.
