The totally redesigned 1177A retains all the features of the original 1177, but adds an attractive, all-metal cabinet, and a new circuit board layout. This 4x1 AutoSelect switch is a perfect solution when digital audio sources outnumber your system's digital audio inputs. The 1177A features both digital coaxial and digital optical inputs and outputs, and automatically outputs the selected audio source in both formats simultaneously.

Four inputs, one output.
