The Artsound Smart Zone 4 streamer functions as a streaming preamplifier for four independent zones, with the option to select a different music source for each. It supports internet radio, Spotify Connect, Tidal, Deezer, Qobuz, Apple AirPlay and playback from a NAS via UPnP/DLNA. It is controlled using the 4Stream app for iOS and Android, while amplification is selected separately.

The zones can be expanded with SMART HYDE devices or by combining two Smart Zone 4 units. The device also features an alarm and sleep timer.
