AMP6-Basic: Whats needed?

[perhem]

Hello!

Just got my AMP6-Basic assembled and since this is my first time I want to make sure I have everything required to get this thing going...

I have:

AMP6-Basic assembled
2x Random speakers, working (dont know efficiency etc but just testing atm) 8 Ohm, 30 watts.. Think they can handle the power! ;>
12V DC 1000mA MAX Transformer (Testing, going with battery later)
MP3 player/Computer

Is it possible to use that "transformer"?
What else is needed and what is important? Anything that I should check before I connect everything?

Best Regards!

Transformers are AC not DC. How are you getting 12VDC from this?
What is the output amperage or VA of this "transformer".
See me sig file below before powering up for the first time (hint a 12V light bulb works well);

Its a 230VAC -> 12VDC Transformer (or converter, dont really know what to call it).
Haven't got the "transformer" here atm (at work ) but will check as soon as I get home.
I will run this using a battery later, but with a "transformer" now just to get things sorted out.

Anything else I need to get it running? :>

Its 12V DC 1000mA MAX Adaptor.

*For use with battery operated appliances
*Short circuit & overload protection
*Equipped with universal DC plug

Should be able to just plug that in, right?

Yes that will do fine, assuming the polarity of the output connector is correct.
Most "adapters" voltage output is rated at full current, in this case 1 Amp. With only a few mA the voltage may be much higher.
Measure the voltage first to determine the ploarity of the connector, and also that the open circuit voltage does not exceed 14.5VDC.

Once again, unless you are 100% confident of your work, use of a current limiting resistor is highly recommended for first power up of any amp.
In case there is a short, the resistor will limit the current to hopefully protect the amp from explosive damage.
A 12V light bulb of 5-7W will probably be OK as a resistor.

Sorry for this newbee question, but where and how do you plug the resistor to protect the amp ?
In series, I assume ?
Just after the transformer ? After the bridge (I have an amp10-b) ?

If you can please give some further details or a small schema it would be very nice !
thanks.

Measured yesterday, right on 12.0VDC. Checked the instructions for AMP6-Basic, read through almost whole forum and finaly decided to try it out. Used a small bulb 5W as a resistor at first. It worked so I removed the bulb then tried it out with a bit more power. Used a random piece of sheet metal as coolingplate to be safe.

WOW is my reaction! Worked like a charm.

Ordered an alu box thats arriving today then im of getting this thing together. Also thinking about the P.audio HP10W but dont really know if I want to spend to much money. :/

It looks like you figured it out. The light bulb goes in series with the power supply.
In the AMP6-Basic, you could just use the light bulb in place of the fuseholder (instead of the fuse) for the first test.
If the light stays on, then you have a short or high current connection somewhere in your amp.

Many thanks for the explanation, scratchy: look like i would have plug the thing at the correct place but wouldn't be able to interpret the signs ...
