musicBox 6 | 12 | 18 System Overview

Providing up to 2 music streams in 6, 12 or 18 rooms

The musicBox Multi-room audio system features a high-quality music experience for your home that you can enjoy no matter what room you’re in. Working, relaxing, entertaining friends, getting ready for your day or going to bed, even just doing housework or laundry -- all these activities are enhanced when you have a whole home audio system providing the perfect background music for everything you do.

We designed the musicBox multi-room home audio system for the DIYer, like you, with superior ease of use and simple instructions. But when it comes to quality, everything about this whole home audio solution is professional grade. The musicBox system is available in six, twelve and eighteen room configurations.

The musicBox multi-room music system includes the CasaTunes music server and one or more CasaTunes 6X6 matrix amplifiers.

The CasaTunes music server is the heart and brain of your multi-room music system, supplying two independent  audio streams to the CasaTunes 6X6 matrix amplifier. Each stream, or streamer, acts as a stand-alone music player. You select the music to play on each player, and which player to listen to in each room.  You can listen to the same music in all rooms, or any combination of rooms.

The CasaTunes 6X6 matrix amplifier operates as a switch, switching any of six input sources to any combination of rooms, and as an amplifier, powering the speakers in each room.
