MusicCast Multi-Room Streaming Amplifier (4 Zone, 8 Channel)
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 from the ground up for custom installation, the “QS” represents the ultimate integrated solution for filling every room in a home with extraordinary sound.
Access all of your favourite music, including built-in streaming services and music libraries on smartphones, tablets and network-attached storage devices.
(Streaming service availability varies by region and may change or be discontinued without notice.)
Want to hear TV sound or vinyl records throughout the home? Link to a MusicCast receiver, sound bar or turntable to access audio from virtually any source.
The QS supports IP control by 3rd-party control systems used in many of today’s most advanced smart homes.
It’s also easy to set up and control with the free MusicCast app, which offers unique personalisation features including the ability to assign custom images to rooms, and to rename, rearrange and hide sources.
No ordinary amp, the QS employs ultra-efficient ICEpower integrated circuits to deliver eight channels of pristine, musically-dynamic digital amplification at 50 watts/channel (8 ohms) with an outstanding 10 Hz to 22 kHz (+0/-3 dB) frequency response and 106 dB signal-to-noise ratio. It is 4 ohm capable at 100 watts/channel and bridgeable to 200 watts/channel (8 ohms).
The curse of the custom integrator: ground loop hum, a common and vexing side effect of connecting a bunch of electronics together in a rack. The QS takes care of it with a brilliantly-engineered differential circuit design. Sometimes it’s what you don’t hear that sounds the most amazing.
Experience every detail of your favourite recordings. The QS supports high-res audio playback up to 192 kHz/24-bit, and employs the same premium ESS Sabre DACs (Digital-to-Analogue Converters) and PML capacitors used in our flagship AVENTAGE AV receivers.
Mount it in a rack with the included ears or remove the ears for shelf installations. The included magnetic faceplate discourages tampering and provides the perfect cosmetic finish.
The QS is truly made for custom integration, with Euroblock-style speaker connectors, dual RJ-45 Ethernet ports and a detachable AC cable for smart connectivity, and IP, IR and 12 V Trigger Out jacks for versatile control.
Access Basic or Advanced settings via a Web Setup menu and store commonly-used profiles for faster configuration of future projects.
