Product Overview

Specially designed for custom integration of whole home audio systems, the "QS" (Quad Streamer) provides four zones of audio streaming and eight channels of high-performance audio amplification in an ultra-slim, 1U-high, rack-mountable enclosure. Expandable and extremely flexible, the QS works with the MusicCast multi-room audio system, allowing it to be linked with home theater AV receivers, sound bars and Hi-Fi gear in a wide variety of configurations.

Designed for custom integration of a MusicCast multi-room audio system connected via Ethernet LAN in a rack or cabinet
Streams four zones of audio per unit, expandable to 32 zones with simultaneous playback in linked groups of up to 20 zones each
Eight channels of audiophile-grade Class D amplification assignable to any zone, bridgeable and 4-ohm capable, featuring a unique ground loop/hum-free circuit design
Built-in Pandora^®, Spotify, SiriusXM Internet Radio, SiriusXM Music for Business, TIDAL, Deezer, Napster and more, plus access to music libraries and linked external sources
Easy control via a free MusicCast app and 3rd-party control systems
1U-high, rack-wide enclosure; removable rack ears and faceplate included
