What type of devices would you connect to a SPDIF? It is primarily used for connecting home cinema (home theatre) systems, Hi-Fi, games consoles, set top boxes, computers, and other consumer entertainment devices. S/PDIF (Sony/Phillips Digital Interface) is a consumer audio connection standard for transmitting high-quality digital audio.

It transfers digital audio signals from one device to another without the need to first convert to an analog signal, which can degrade audio quality. S/PDIF (Sony/Philips Digital Interface) is an audio transfer format interface. Such soundbars many not have HDMI inputs anyway. Fiber optic cables won’t be able to transmit these high-res sound formats. The major difference is that HDMI cables can pass higher resolution audio which includes formats found on Blu-ray like Dolby TrueHD and DTS HD Master audio. Is it better to connect soundbar with HDMI or optical? In terms of value for money, aux cables are usually cheaper, more versatile, and most commonly found on modern devices than their digital counterpart. Higher quality aux cables can also help as they’re better shielded. The Biggest Difference: HDMI is better because it’s capable of passing higher-resolution audio that’s uncompressed, which includes extra formats that won’t translate as well through optical cable and S/PDIF like Blu-Ray’s DTS HD Master Audio and Dolby TrueHD.

While a SPDIF coaxial connection looks like an RCA analog type connection, it is not the same. You must have a very specific SPDIF digital cable. The signal is transmitted over either a coaxial cable with RCA connectors or a fiber optic cable with TOSLINK connectors. S/PDIF (Sony/Philips Digital Interface) is a type of digital audio interconnect used in consumer audio equipment to output audio over relatively short distances. This is beneficial since such a conversion can hurt audio quality. S/PDIF is an optical audio cable format that allows the transfer of digital audio signals from device to device without needing to convert to an analog signal first. S/PDIF coaxial with RCA connectors can be converted to optical. 5 Is RCA cable and SPDIF cable the same?.
