Two classics in one chassis, the B172A marries the Seventeen version of the legendary “76” FET limiter with their take on the renowned “2A” tube optical compressor. Whether you use the FET and opto separately — or in series, where one catches the audio’s peaks and the other provides the heavy compression — the B172A will blow you away with its incredible sound and versatility. The B172A’s Dual Mono Link makes it easy to route your signal through the 17 and 2A circuits in any order. Painstaking effort went into choosing the best transformers needed for each circuit. Spec’d with a CineMag input transformer on the 2A side, BLA’s own Chicago-wound output transformers on both circuits, high-grade signal path and decoupling capacitors, the B172A gives you ultra-convenient access to a pair of classic dynamics processors while also providing a valuable signal processing tool never before available in a single chassis.
