How to choose AV Receiver
AV Receiver is the centre of the home cinema experience. It connects together the sources which include the speakers and display. AV Receivers may look complicated and overwhelming, but that’s why we’re here to summarise it for you. Basically, what you need to gather is: how many speakers do you have, how many HDMI inputs will you need and what’s your budget?
Since most of us are stuck at home due to the lockdown, you might want to have a surround sound system in your home and you probably already know how many speakers you can fit in unless you just moved into a new home. If you only have room/space for five speakers and a subwoofer, then all you need is a five-channel AV receiver but if you have a large room/space and/or are planning to expand, perhaps even getting an Atmos system.
Then, we’d recommend looking for an amplifier that lets you accommodate four Atmos speakers, a 5.1.4 or 7.1.4 configuration instead of two 5.1.2 or 7.1.2. Besides that, you’ve also got to consider the connection. You’ll need to make sure you have enough HDMI input if you’re got multiple sources and that they support the latest 4K and HDR specifications (HDCP2.2, HDR10, DV and HLG) if your film collection is increasingly full of 4K HDR Blu-ray discs. Besides Atmos, there is also DTS:X. Their function is pretty much the same. Both are surround sound format designed to create a 3D-like sound for a more immersive audio experience
– The first number stands for speakers and there are 5, so 5 speakers
– Second number stands for subwoofer and there is 1, so 1 subwoofer
– Third number stands for height speakers, speakers that are above the ground and there are 4 height speakers.
In summary, you’ll need to check your current devices for connections. For example, if you have a Blu-ray player, Playstation and an Apple TV then you’ll need an AV Receiver with at least 4 HDMI inputs. You’ll also need to make sure your AV receiver is ready for your TV and what type of TV you have. Besides that, how many speakers can your room fit. No reason to go looking for a 20-channel AV Receiver if you don’t have the room/space to fit 10 speakers.
