Phorus

Phorus uses DTS Play-Fi technology to power simple, great-sounding whole-home wireless audio. Stream Hi-Fi over Wi-Fi from your phone to Play-Fi speakers across the house, in one room or all rooms.

The app supports built-in streaming from music services, Internet radio, DLNA servers, and your device’s library (including iTunes playlists). It also handles speaker setup, volume control, and grouping, including Spotify Connect integration. Note: this is a companion app for Play-Fi-enabled products and is not a stand-alone audio player; for Polk Audio, Definitive Technology, or Phorus, use the brand-specific Play-Fi app.
