Omg Wow! Dls A7 Is An Amazing Work Of Art! Pics Inside...

Soundstream used to use this exclusively, they called it "chassink". It made repairs pretty tough, and trouble shooting tough as well. I don't think they use it anymore.

Sweet figured two things out. They are getting away with useing 85c caps because all the heat or most of it is on the opposite side of the board! Awsome design! The boards are rubber isolated to help shock but also to press the mosfets into the heat sink! Freaking awsome! Never seen a design like this. Most hang the mosfets off the sides into a rail to dissapate heat. This one uses the whole top fin surface to cool! Sweet! You can see the drawing of the mosfets in this photo, they are directly under the board drawing!

And then again here...

Anyone else use this kinda design..? I have not seen it but it totally makes sense. Lets you use allot smaller chassis and get rid of heat faster!

that sucks, was hopeing to see the pair soon!

Pinny @ DLS came though big time...I'll be a father of twins come tomorrow..hehe

Just wondering, the blue cylinders are obviously the transistors, but what are the circular devices with wire coiled on them?

The blue cylinders are capacitors. The transistors are the small through hole devices soldered below the blue caps; they are black and with a shape like half circles. The ferrite cores with coiled wiring are toroids.

yep, you cannot see the mosfets, they are under the board "aka transistors"

I think this is only a single sided board with all the components being on top side as shown in the pics. It's a combination of both through hole and SMDs.

Thanks for the help, transistors and capacitors sound too much alike to guess which one looks like what to me, both use separate layers of metal ect, though i guess if those were the transistors it would be a much different amp. This is kindof random, but does anyone have any idea what a superconductive subwoofer would sound like? I'm doing a research paper on superconductivity and that idea just came to mind, I havn't come across any information of superconductive loud speakers but it would be nice to read.

it would sound like unobtanium iridium goncuelation.

Correct, however it is a very THICK single sided board. Not crappy thin floppy board that cannot support it's own weight in components!

What are the stats of this amp? It doesn't make sense why it is so complex... all that just to amplify some signals?

google "dls a7"

And mine is going back to the hospital because it died on me today //content.invisioncic.com/y282845/emoticons/crying.gif.ec0ebefe590df0251476573bc49e46d8.gif Tried everything known to man and can't get her out of protection.

Called the dealer and he's bring me a new one. Just a heads up for you DLS freaks out there (incase you haven't seen it already): http://www.dls.se/english/fake_products/fake_copies.htm

Good thing you bought authorized //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

lol, but if you used the right superconductor you could have perfect diamagnetism, the repeling of a magnetic field completly, and im sure that would be able to create some noise,but if you made an entire system of the superconductive material would it not be a perfect signal, which would sound...perfect.
