![]() Just make sure that the subwoofer you buy has a high-level input. You can then use a built-in filter and volume control on the sub to balance the amount of bass with that from your front speakers. It takes a full-range speaker signal – taken from the same outputs that power your stereo speakers. Many subwoofers will have what is known as a high-level input.Ī high-level subwoofer input is different from the more common low-level input. However, that still doesn’t mean you can’t use a subwoofer. There are a few about – like the Cambridge Audio CXA61 pictured here – but as a rule, most stereo amplifiers won’t have a subwoofer output. There aren’t so many stereo amplifiers with a subwoofer output – and if you find one, they are usually the more expensive models. However, if you are hoping to use a stereo amplifier/receiver for a 2.1 sound system – front left and right speakers with a subwoofer – then you should be careful.

So why might you want a stereo receiver rather than a multichannel AV receiver?įirstly, and probably the main reason is that a quality 2-channel receiver will probably give you more bang for your buck – a better quality sound at a cheaper cost.Ī stereo receiver/amplifier only has one purpose – to amplify the sound. You may well use the receiver purely as an amplifier – and may not even use the built-in tuner. Well, the stereo receiver just has one of these built-in.Īpart from that, there is no difference between an amplifier and a receiver. Some of you may have a separate radio tuner unit as part of your Hi-Fi setup. You will also have all the other 2-channel inputs just like an amplifier to plug in your CD, DVD player, PS3, etc. The receiver will probably need connecting to an appropriate aerial/antenna to receive the radio signal – but you can pick up radio channels on the receiver and send this to the speakers. Most music and TV sound are produced using stereo audio. This type of amplifier has two speakers connected to it – audio left and right. ![]() Stereo amplifiers take the 2-channel stereo audio output signal of a device, and then send this audio to the connected speakers.
