How To Pick The Right Receiver For Your Home Theater Needs

AV receivers are combined amplifiers and input selectors – a crucial component of a home theater system Building A Home Theater System? Do It Right! 10 Crucial Mistakes To Avoid Do an image search for "home theater" and you’ll see photo after photo of huge, lavish theaters with seating for up to twenty (or more!) and giant screens. These ideals are every tech geek’s dream,... Read More . They switch between all your HiFi and TV components, drive your surround sound speakers, and send the video signal out to the TV. That’s basically it – they are the central hub all of your AV equipment. Yet there’s a huge range of receivers on the market, so the choice can be a little overwhelming. What exactly should you be looking for in a new AV receiver?


This article is aimed at the regular Joe – if you’re an audiophile who cares about the exact DAC chipset, you’ll probably splutter at various points. Please don’t think this article is aimed at you!


It’s very easy to underestimate the number of inputs you’re going to need. While your needs might not be quite as ridiculous as our esteemed gaming editor Dave LeClair and his hundreds of retro gaming consoles, you may be surprised how quickly those inputs get used so always buy a model with more than you need to allow for future expansion. Five of my HDMI inputs are already in use.

Start by making a list of all the equipment you need to connect to the receiver, and the type of connections they need – older equipment may have:

  • Component audio and video (5 RCA plugs)
  • SCART (mainly European)
  • Stereo audio (2 RCA plugs, or just a 3.5mm single jack)
  • Composite audio and video (3 RCA plugs – red/white/yellow)
  • TOSLINK optical audio

Most receivers will be able to accommodate perhaps one or two of each legacy device, but the main number you find advertised will refer to the number of HDMI inputs.



A mesmerising array of sockets awaits you at the rear of an AV receiver!

It’s safe to say that any expansion you need will be in the form of HDMI. HDMI is the modern standard for transmitting digital audio and video signals – one cable to rule them all. Even the previous generation of games consoles use HDMI, and most computers now include HDMI output sockets. When calculating how many inputs you need then, add a few to allow for future HDMI devices.

Higher end models may also support more than one HDMI output, to allow you to choose between a TV or projector How to Set Up a Projection-Based Home Theater, Step by Step Watch movies on the big screen, at home, with the perfect home cinema set up for any budget. Nothing beats the big screen experience for movies or gaming, but home theater is an expensive hobby... Read More , for instance. You won’t find this in budget models, so a simple external HDMI switch/matrix can be used instead.

One caveat to look out for: 3D equipment and AV receivers don’t play nice due to differing HDMI standards. Unless you buy a receiver specifically designed to work with 3D signals, you may be stuck connecting your 3D devices directly to your TV or projector. This won’t affect most of you, but worth bearing in mind.


4K Passthrough and Upscaling

The newest video standard to arrive in the next few years is “Ultra HD”, or 4K – if you want your receiver to be compatible, make sure it features 4K passthrough. Of course, you’ll need a TV capable of displaying that too. Matt Smith’s advice was to basically avoid 4K TVs for now Should You Buy A 4K / Ultra HD Television? About a decade ago, manufacturers started to sell what's now widely known as an HDTV. But now HD is old news, so the industry has decided to push another new technology; Ultra HD, also known...

Upscaling means your receiver will convert a lower resolution video source to a higher resolution – 1080p, or even 4K on very high end equipment. Unless you have money to burn and are particularly attached to a very old device, forget upscaling, you don’t need it – and your TV probably does a better job of it anyway.

Surround Sound Channels and Power

Surround setups range from 5.1, 6.1, 7.1, 9.1 to a rather ridiculous 11.1 speaker system. The “.1” refers to a subwoofer, responsible for bellowing bass sounds; you may even find “.2”, which means it supports two subwoofers like the Onkyo TX-NR616. A good 5.1 setup is more than sufficient for the average living room, but some Blu-ray movies are encoded for 7.1 if you’re after the absolute best.



Discussing audio decoders like Pro Logic is a little out of the scope of this article – suffice to say, your receiver should at least handle DTS and Dolby Digital (used for movie soundtracks), and Dolby Pro Logic II (which can process a stereo source into 5.1 channels).

Power refers to the sound output per channel – usually around 50 to 150 watts. The speakers you buy should be of a matching power for the best performance. Larger rooms require a higher power. The physical size of a speaker is largely aesthetic and has little to do with the quality of the sound it produces, so don’t just think “bigger is better”.

You can save money by buying an AV receiver and surround speaker set deal, and you won’t have to worry about matching up power ratings or impedance values.

Connectivity and Extra Features

Many receivers will now add additional connectivity with computers, mobile devices, or network storage. Here’s some keywords to look out for:


If you have a computer, media center, smart TV or gaming console, most of this functionality is already available, so don’t base any judgement on these added features. If you have them, that’s nice, but certainly don’t pay extra – these features tend to be outdated rather quickly as new services come along.


Cheat Sheet

  • Allow for a few more HDMI inputs than you need; make a list if you have specific requirements for older components, or be prepared to buy an adapter/converter.
  • Future-proof with 4K passthrough, but it’s not going to be essential for a good few years yet.
  • Forget upscaling.
  • 5.1 surround is more than enough; bigger rooms will require a greater power rating though (around 150w).
  • Save money and hassle by buying an AV receiver and matched speaker set.
  • Don’t worry about gimmicks like Spotify or DLNA.

Budget AV receiver sets start at around $300 for a complete package, and truly offer excellent value for money. At the top end, an AV receiver alone can be $2500. Onkyo, Denon and Yamaha are all reliable brands – don’t go for a no-name import. It’s always a good idea to actually visit a showroom and listen to the system first.

    I had an Onkyo 7.2, lasted maybe a 2 years, they get very hot to the touch. The HDMI board replacement cost was more than a new unit.

    I ended up finding a new Pioneer SC-1522 THX9.2 on Ebay. Runs cooler, works with iPad app and connects 11 speakers with 2 subs. I'd get 7.2 or 9.2, even if you don't have all the speakers, you can add them later on. With two subs you don't need to turn it up much as with one, the two together have a nice deep punch that you'll feel and won't distort or bottom out.

    Gimmicks like DLNA? What!

      All DLNA does is let you view movies, music, and images from other devices (PC, laptop, phone, tablet, etc) on your large screen television and fancy surround sound system. Why would anyone want their $300 (minimum) audio video receiver to be capable of this?

      DLNA is actually one of the main reasons for our present system!

      A gimmick, yes. Incompatible formats, different implementations. It's not defined as rigidly as it should be to be truly useful. If you have a combination that works, thats awesome - but I'd be hesitant to recommend anyone go out and actually buy something on the basis of it has DLNA. A decent media center and network share would be far more compatible.
