In part 1 of this two part video, we looked at 5 of the 10 common mistakes people make with their home theatre audio. In this second and final part we will be looking at the remainder; and you can’t talk about sound without talking about cables. There’s a huge amount of hype around the benefits of pricey, high quality cabling. But in today’s digital world there is no advantage to be gained through spending a fortune on wire. Though that doesn’t stop manufacturers from trying to convince you otherwise. The only thing you should be concentrating on is getting cables that are only as long as they need to be and picking the most appropriate digital connection for your system. Unlike mid and high frequency noise, low frequency sounds are largely directionless. Which should mean you can put the subwoofer anywhere you like without ruining the surround affect. However, the overall performance of the sub is dictated by it’s surroundings. They greatly benefit from being placed carefully. You ears will always be the best guide for speaker placement. Positioning the subwoofer a few centimetres away from the wall can improve performance. Finding a convenient and attractive message for getting the audio to the source and every speaker in the room is a challenge. Which is why some manufacturers have produced what they describe as wireless surround sound systems. Typically used in radio transmissions to get an audio signal to the rear speakers. While this eliminates the needs for signal wires it introduces the needs for power cables. So what you’re really doing is swapping one annoyance for another. One of the biggest advantages of HDMI cables is that they can carry both sound and video. Which significantly reduces the amount of clutter around your home theatre components. However, with a sound system that’s seperate to your TV, you have to split the audio and video signal between two devices. Some system provide a pass through feature that does exactly this. While some simply pass the whole thing; audio and video over to your TV. So check the spec to make sure that you have chosen the model that does the former. Or at least supports the seperate means of digital audio input. Finally, it’s a common misconception that hearing clear, individual sounds from each individual speaker means your surround sound system is working well. While it’s true that positional audio should do exactly that, good surround sound is all about immersion. If you’re watching a scene set in a thunderstorm for example you want to feel like you’re in the middle of the action. And not like Rolf Harris standing here behind you with a wobble board. So now you know what the most common mistakes are you should be able to avoid making them when it comes to buying your own surround sound system.
