The player is equipped with a variety of input/output options including six-channel analog RCA outputs, dual RCA analog stereo outputs, S/PDIF PCM digital output, TOSlink optical output, composite video output, S-Video output, and component video output. The SA-12S1 features a 10-bit video DAC and employs a dual differential topology for its HDAM modules and Crystal DACs. It boasts a toroidal power transformer and separate transformers for display functions, and its internal design includes heavy shielding with both dual plate steel and copper. Notable specifications include dimensions of 18" x 5" x 15" and a weight of approximately 24 pounds.

The SA-12S1 is designed for those who appreciate a more forward and engaging sound signature as opposed to the smoother, more relaxed characteristics of its predecessor, the SA-1.
