I need a mini amplifier

Post by mr x » Wed Jun 22, 2011 6:12 pm

Don't need a radio, or lots of options, just a set of rca inputs and 4 speakers out, preferably 80w or higher. Maybe something like this:

Ideas?

What is the application? Four independent speaker outputs or just stereo driving 4 speakers? What impedance are the speakers? 80w to each speaker or 80w total?

I have a good tuner that I want to set-up in the kitchen, with 2 speakers outside, and 2 inside. I haven't picked out the speakers yet, because I thought I should start with the amp. 80w per speaker, but could probably go with 60 or even 40 I suppose. Don't want to spend too much, but I will probably wind up with a big integrated amp anyway - seems that's all there is anymore.

Yea the consumer market has gone to totally integrated solutions. I'm using a $400 studio amp to drive my computer speakers, If I had my time back I would of gotten speakers with integrated power amps.

Something like these look like really good value and near audiophile level quality: http://kellysmusic.ca/productinfo~s~STU ... 187703.htm" onclick="window.open(this.href);return false;

The main difference between the speakers above and a traditional system is that the ones above have separate amplifiers for highs and lows that are perfectly matched to the drivers. With the highs and lows powered separately there is less interaction between the two and thus less distortion. I wish I understood it better to explain it better. You also don't get any power loss from cabling between the amp and the speaker drivers. In the past decade most of the mid range pro PA systems have gone this way. Well the larger systems have almost always had separate amps for high, mid, low and sub. The new trend has been to put the amplifier right in the back of the speaker cabinet.

Outdoors having the amp built right in doesn't work out so well do to moisture and cooling issues. Sure you can make an amp that is totally sealed but then you have trouble keeping it cool. I dunno off hand if there are any good powered outdoor speakers at a consumer price.

Well if its just radio I would just pickup a cheap bookshelf system. The full system will cost less than a single speaker or amp from a component system.

Yeah, probably the simplest option. They are just such fucking junk though, and I'd likely still need a set of outdoor speakers...I guess I want the best of both worlds, lol.

You can use the bookshelf system to drive the outdoor speakers, if you don't push it you could run both the set that came with it and the outdoor speakers at the same time. Otherwise just wire up a 4 pole double throw switch between the inside and outside speakers.
