Toshiba originally created TOSLINK to connect their CD players to their own brand receivers. As time passed, it ended up becoming a popular format for digital audio output from some devices - but mostly from TVs to receivers. If your newer TV does not have a HDMI out to go to your receiver, then you usually have a toslink (or optical) out for the audio. This format does not carry any video. So, if you’re looking to couple, split, or convert your TOSLINK connection - you’re all set with the merchandise listed below.
