Description
The new SpeakerCraft MRA-664 is a complete home audio controller that delivers up to six unique music sources for stunning sound in every room of the house. This MRA is the first to integrate multi-room audio with home theater control for easy setup and great listening.

What once might have required hours of programming has been reduced to simple execution. For larger residences, two MRAs can be paired to create a six-source, 12-zone system. That means 12 rooms, each with music porting. Additionally, all zones are equipped with fixed or variable pre-outs, making it easy to increase power and volume with our new SpeakerCraft amplifiers (SC2-50, SC2-100, SC2-150, SC12-30 or SC16-50).
