Like the MAS 100, the MAS 110 is built around a high-efficiency, two-channel Class D amplifier and powerful digital signal processing (DSP) technology. And like the 100, it delivers best-in-class audio performance with proprietary flat-panel bass drivers and waveguide MMD® tweeters. So what makes the MAS 110 different? A DAB+ (digital audio broadcasting plus) tuner for interference-free digital radio. With a compact system that makes everything sound as great as this one does, interference simply cannot be tolerated.
