Lexicon NT-312 (same as Bryson 5B-ST)

Lexicon NT-312 3-channel lineup from one of Lexicon's best amplifier series, which was relabeled from Bryston.  Perfect for the three front speaker channels, or various other options. Channel 1 and 2 can also be bridged!  One benefit of the Lexicon over the Bryston models is that 12V triggering was added to these units, and the Lexicons were THX certified.
