ratty05 Posted September 29, 2008 Posted September 29, 2008 Hi Guys, Can someone please give me a simple explanantion of what a pre amp or pro amp does? I've had a look in the FAQ's but they seem to discuss models and I know nothing about them. I currently have a Yamaha 2700 and was thinking about either upgrading for new HT or if the purchase of a pre or pro or whatever is suitable would be better but I have no idea what they do? Thanks.
Shonky* Posted September 29, 2008 Posted September 29, 2008 A pre/pro (I think short for pre-amp/processor) is basically a receiver without the amplifier. i.e. an external amplifier is then required for a full system. The concept is that it allows for a good external amplifier that doesn't need upgrading and also allows for a better/larger amp without having a massive receiver. Just like taking a receiver with pre-amp outs and feeding an external amp like an Elektra or Rotel. Except in that case you are paying for the inbuilt amplifiers which are ultimately left unused.
Juicester Posted September 29, 2008 Posted September 29, 2008 keep in mind obviously that you can have pre and pro's which are seperate too. A seperate pre-amp and seperate processor. This, running along what shonky said, is to ensure that you've got the best in each stage, rather than a mish mash of the two (or all three if you consider what an AVR does). The biggest let down of recent processor's was their inability to decode latest codecs and having HDMI inputs (1.3 anyway). Now the new batch of 'pro's' are out, there will be a lot of happy people.... if you can afford to go down the seperates route of course!
dantan Posted September 30, 2008 Posted September 30, 2008 In terms of pure sonic ability, having everything separate is ideal but in most cases unpractical. Having a separate surround sound processor and dedicated power amplifier would be superb, but most people simply end up purchasing an A/V Receiver because it is only one 'box' compared to two separate 'boxes'. Having the more sensitive surround sound processing completely separate to the amplification side is ideal, as there are less chances of interference, etc.
SDL Posted September 30, 2008 Posted September 30, 2008 In the olden days, prior to the all in ones this was about the only way to go. I still have my HK Dolby Surround Processor and 3 seperate amps, one for centre bridged, one for fronts, one for rears, all collecting dust. I keep meaning to use them on the family room TV but just don't get around to it.
