The Digital 2-way o converter is a Coaxial / Toslink o converter, compact and convenient. It accepts S/PDIF o signal input through either Coaxial cable or Toslink cable, and passes the signal (as is) to both its coaxial and Toslink output ports. Optical to Coaxial o: This bi-directional digital o converter splits the optical signal from your optical source (such as Blu-ray Player or Satellite Receiver) to your Speaker or Amplifier, providing both optical and coaxial o output simultaneously. Coaxial & Optical o Adapter: It splits the coaxial signal from your coaxial source to your Speaker or Amplifier, delivering both optical and coaxial o output at the same time. Use the switch on the side of the converter box to select Optical input or Coaxial input. Long-distance Transmission: With a built-in amplification chip, this dual-way o converter can also function as an o signal repeater, extending the transmission distance.
