Product Description

The Linear Acoustic® MT2000 Bitstream Analyzer is a portable, handheld diagnostic tool that can monitor and generate Dolby® Digital, Dolby Digital Plus, Dolby E, and PCM bitstreams.

With its built-in test-signal generator, the MT2000 allows audio system integrators and service engineers to quickly monitor and check the integrity and composition of Dolby encoded and PCM signals routed through production, broadcast, cable, satellite facilities, or even a home theater system.
