To connect two optical audio signals to an audio output, this switch smoothly, probably only succeed without any problem with a splitter that sends signals elktrisch strengthened. For this purpose, this splitter, which is also available for four inputs, ideally suited. When connecting my PC to the TV via HDMI cable 5m, I wanted to spend both the audio from the PC as well as the sound of the TV (1.5m HDMI cable) about my audio system. With a simple distributor worked not because the signals have overlapped. With the Audio Splitter SPDIF DIGITAL PORT 2 the reason goes smoothly because one connects the electric connection of each input via switch separately with the audio system. The splitter is well to accommodate its size, though the small switch to it is a bit fiddly. A pressure switch would probably be more comfortable. Also you have to take the necessary power supply for the electrical transmission in purchasing. Ultimately, however, the secured function is important and the workmanship is of high quality. Conclusion: the audio signal is as promised (to 5m) transfer prima and switched smoothly. Recommended.
