CONNECTING SOUNDAR TO NON ARC PROJECTOR TV
Peer around the back of your TV – if it’s packing three or four HDMI sockets, you need to find the one that’s labelled 'ARC' or 'eARC' (we'll get to the second of those shortly). To take advantage of HDMI ARC, you’ll need a television and audio processor (AV receiver or soundbar) with ARC-enabled HDMI sockets. HDMI ARC removes the need for an optical cable and allows you to send audio ‘downstream’ from a compatible HDMI socket on your TV to a compatible HDMI ARC socket on a soundbar or AV receiver. Previously, you would have to connect an optical cable from the back of your TV to an optical input on your audio device.īut that’s a messy solution. Either way, you don’t want to use your TV’s speakers for audio – you’d rather hear everything played through a soundbar or AV receiver instead. Or perhaps your smart TV is using a built-in video app such as Netflix, Disney+ or Prime Video. You have a set-top box, games console and Blu-ray player all plugged into your TV via HDMI. It was introduced as part of HDMI version 1.4 and has been part of the specification ever since. It wasn’t until 2009 that the HDMI ARC protocol was added to the spec sheet. The HDMI interface has evolved over the years, with new versions ( HDMI 2.1 is the latest) bringing support for new audio and video technologies such as 3D, 4K, 8K, HDR and high frame rates, to name but a few. As HDMI has become the de facto AV connection, traditional analogue sockets such as SCART and component video have found themselves consigned to the spare parts bin. It was billed as a convenient way to send high-quality digital picture and sound data ‘upstream’ from a source to a TV, amplifier or soundbar.
HDMI launched way back in 2002, and the first consumer kit to feature this high-tech connector hit the shops in 2004.
