For proper operation, both input and output jacks of both sub-units must be wired; in A-B mode, the signal runs from input 1 to output 2 and vice versa.
Black Lion Audio presents with the Black Lion Audio B172A two popular compressor circuits in one housing: On the left is a unit of the Seventeen FET compressor. In terms of operation and function, the Seventeen is based on the Urei 1176, but is not a replica of this classic, but instead convinces with a much more open, treble-emphasized, but also powerful sound. On the right side there is an opto compressor based on the Teletronix LA-2A. Here
Both compressors have their own inputs and outputs, but can also be linked internally and swapped in sequence. A switch on the front is provided for this purpose. In addition, both can be switched separately to bypass, which was not possible with the big models. If you own two B172As, the two units can be linked together via link jacks to form a stereo pair.
Black Lion Audio delivers one of the most popular and successful device combinations with a fraction of the space requirement and at an attractive price - in addition developed with expertise and manufactured to a high standard. The
