What is a digital audio output cable?
Beside this, what is digital audio output?
From Lifewire.com. A Toslink (or optical) audio output is a fiber optic connection that makes use of LEDs to transmit digital signals from the source to the receiver. Similar to the SPDIF, it is a reliable way of transferring signals and is able to carry 2 uncompressed or compressed signals (in 5.1 or 7.1 sound).
Subsequently, question is, is digital audio output the same as optical? Unlike other cabling standards, the optical audio system uses fiber optic cables and laser light to transmit digital audio signals between devices. The port is typically labeled “optical audio”, “TOSLINK”, “Digital Audio Out (Optical)” or something similar, but you certainly don't need a label to identify it.
Considering this, what is the optical digital audio output for?
Also known generically as an "optical audio cable" or just "optical cable", its most common use is in consumer audio equipment (via a "digital optical" socket), where it carries a digital audio stream from components such as CD and DVD players, DAT recorders, computers, and modern video game consoles, to an AV receiver
How do I connect digital audio to speakers?
Most likely the input on the stereo or home theater receiver is an RCA jack. For digital connections, locate an unused optical digital or HDMI input port. Using a cable with the appropriate plugs on each end, connect the audio output from the television to the audio input of the receiver or amplifier.
