The B-220-DAC is the solution for newer devices that do not have analog outputs. It converts the 2-channel PCM signal into an analog signal that can be used in a multi-room audio system. And unlike competitive models, this is the only DAC you need since it features both optical and coaxial inputs. This Binary product has a 2-year limited Warranty.
