Gainclone PCB

[The Dudster]

Been lurking on the forum for a while and have seen many threads regarding gainclone PCB's. None of them seems to be complete though, the person who designed them forgot a trace here, a component there or made the tracks to narrow for high currents.
Is there someone out there who has layout files for a fully working PCB? It just needs to be a very simple layout like the one on the application note. I need to build 24 channels in one enclosure, so the PCB have to be small. They will be run from a dual supply of +/- 14 VDC driving 12 x 6ohm tweeters and 12 x 5" 4ohm woofers. For my surrond speakers...

Eeeeeh, Ok, I should have searched. Sorry.

Thanks though, just what I need and it was so sexy too, red and all.

It sounds like http://www.fedde.tk ]Fedde[/URL] is the guy you need to contact. He has PCBs finished and they are ultra-compact.

PS He is in Holland.

so this question is most likely stupid.
I understand the stereo set up of an amp you have 2 channels a left and a right.
But if you want to start to build a 4.1 , 5.1 6.1 or as it seems a 7.1
how does one go to split up the channels into rear, front and center etc... channels
do you need some kind of electronic splitter that splits each of the 2 incoming source channels into multiple or how does that work?
plpease not toooooo technical, I was born stupid!

usually the source (computer/dvd player etc) will have the 5.1 7.1 whatever outputs..
so its a simple matter of having enough amplifiers for each channel

I "think" building a DAC which support mutipule channel will work too.

I have been looking at an old Pioneer system with surround sound
front R L, rear R L and center speaker
I can hear definitely different sounds coming form different speakers (depending on the film ofcourse) but the dvd out is only 2 rca jacks for audio ( frankly I have never seen a cable leaving a dvd player that had more than 2 rca jacks for audio....




for a DAC can you give me an 'easy' schematic
I would like to look at that and I understand that for each speaker I would need it's own amp so for a 6.1 i would need 7 amps, but considering the small space a gc takes i could do all of that in a relatively small enclosure seperated from the powersupply

The 'better' HT receivers have separate preamp outputs for each channel. If you're going to roll your own amps, then you should consider a HT preamp/processor like the Outlaw Model 950.

There are no DIY solutions for a HT receiver because of licensing issues.

Here is the rear panel of the 950 with all the preamp outputs (and other connectors).
