Multiple Stream Box S2 units can form a multi-room setup, and two units can be paired as a stereo pair with assigned left and right channels. Output options include fixed line-level RCA, variable mini-jack for powered speakers or power amplifiers, and optical digital for connection to a dedicated DAC.
