Optical Audio Adaptor

Product Information

S/PDIF (Sony/Philips Digital Interface) is a type of digital audio interface used in consumer audio equipment to output audio over relatively short distances. The signal is transmitted over either a coaxial cable with RCA connectors or a fiber optic cable with TOSLINK connectors. Also, coaxial doesn't have the bandwidth required to support high-quality surround sound formats such as Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos and DTS:X. So, in a modern home cinema setting, its uses are quite limited. But don’t be tempted to try and use a standard RCA phono cable in place of a dedicated coaxial digital cable. They look similar and can work, but an analogue interconnect has different impedance values from a digital one (50 ohm versus 75 ohm), so won’t work as well. An entry-level cable like the QED Performance Coaxial will do a fine job for most.

Although the cables are fiber optic, the output isn't very powerful. The laser system your local fiber internet service provider uses might be able to shoot a signal down several thousand feet of fiber optic cable, but your TV's TOSLINK port certainly won't. TOSLINK is just the shortened trade name for Toshiba Link, both named for the company that introduced optical audio as a consumer standard.They could easily update both to support full bandwidth, all formats but it's all about HDCP, which is a shame. Also, maybe Toshiba invented the original digital toslink connected but both are S/PDIF, which was created by Sony and Philips.(see below). Let's look at three common situations where it is beneficial to use TOSLINK over HDMI. Keeping Older Audio Gear In Service

The majority of TV and AV products launched over the last few years support HDMI version 2.0, but HDMI 2.1 (which supports 8K resolution content and features such as ALLM) is becoming more common among modern TVs and AV kit.You'll find HDMI inputs and outputs a firm fixture on the best TVs, Blu-ray players, AV receivers and, increasingly, soundbars. An entry-level cable like the AudioQuest Pearl HDMI will suit a wide range of systems.

The consumer version of the TOSLINK standard has stayed stable for decades. A TOSLINK optical audio cable from the 1990s will work just like one you buy today.And, in our experience, compared to optical, a coaxial connection does tend to sound better. That's because it has greater bandwidth available, meaning it can support higher quality audio up to 24-bit/192kHz. Optical is usually restricted to 96kHz. spk said:so assuming that the dac is equal in quality i would convert at the receiver. I could be mistaken, but my impression is that analog signals, especially unbalanced, low level signals, are susceptible to noise whereas digital signals, especially optical, are not. So you want to keep your analog signal path as short as possible.
