DCT-2 is a Coaxial / Toslink audio converter, compact and convenient. It accepts S/PDIF audio signal input through either Coaxial cable or Toslink cable, and passes the signal (as is) to both its coaxial and Toslink output ports. With its built-in amplification feature, DCT-2 can also serve as a repeater of audio signal and extend (double) the transferring distance.
