Hi everybody!
I've built a small amp based on the "Texas Instruments Evaluation board - TPA3008D2EVM" which is a 10-W Stereo Class D-Amplifier.
(http://focus.ti.com/docs/toolsw/folders/print/tpa3008d2evm.html for more info)
I'm having problems with static noice (as i think its called, correct my non native English I'm mistaken), as soon as i connect a cable to the input terminals. I don't think its the cable (which is of low quality though) but works fine with other amps ...
The amp looks like this;

The cable beeing used is a simple RCA - 3,5mm jack, like this one;

Im a little short on other input sources, but im gone try a preamp i have available, and see if that makes a difference ....
Any ideas, anyone?
