CT-12X8MA CasaTunes 12X8 Matrix Amplifier

The CasaTunes 12X8 is our most powerful offering, designed for high end projects.

The CasaTunes 12X8 combines an audio matrix switch with six stereo 110W power amplifiers, and two dedicated pre-amplified outputs. The number of rooms configured can easily be expanded by adding up to 7 additional CasaTunes 12X8 matrix amplifiers, for a total of 96 rooms.

With 12 input sources available, the CasaTunes 12X8 is designed to complement our 2, 3, 5 and 8 stream music servers. Any unused input sources can be used to connect various audio components, including TVs, set-top boxes, Google Chromecast, Amazon Echo Link, SONOS Connect and Port devices, phonographs, and other components.

You can listen to any input source in any room or combination of rooms. The built-in hardware audio switch results in perfect synchronization and near-zero latency, ideal for switching TV audio, as well as music.

If more amplified zones or power is required, the CasaTunes 12X8 offers 2 pre-amplified and trigger outputs, which can be used to connect to, and control, a secondary power amplifier (such as the CasaTunes CT-2100A and CT-250A stereo amplifiers)

The CasaTunes 12X8 matrix amplifier supports 8 optional keypads that can be assigned to any room. The keypads integrate an IR receiver which can be used to relay IR signals to the source equipment selected for the room.

Other advanced features include an LCD Touch Panel display on the amplifier unit for setup and/or maintenance, system and zone protection, subwoofer pre-amplification filter support, gain adjustment for each input source and output, configurable audio delays, support for presets, and multiple EQ settings for each room, including a 7-band parametric equalizer, loudness, bass, treble and balance.
