I'm not clear on the four pins of the DC power supply for the speakers. Do you think there two different voltages needed??? It's not worth trying to convert your ac power supply/ It would take a few parts and you will not end up with 18 vdc. You can purchase a 18 v dc adapter for as little as 15.00.

Plug the power supply into the wall and the power cord into teh speakers. Plug the speaker wire into the speaker and the othe end into the musice source. turn on the speaker volume to mid rand and play some funky music!

This worked for me on my M604: Try inserting/removing a headphone plug into the jack several times to see if that clears the problem.

The "popping" sound is very similar to the sound that the unit makes when inserting headphones into the 'headphone' jack on the back of the unit.

The jack has a contact switch that triggers a relay inside the unit. If that contact switch is 'on the verge' of making contact, slight temperature changes may cause deform closer to it's contact target. The subsequent capacitance build-up and discharge across the gap could explain the cycle of popping noises after the unit warms up.

1. Check that the speaker input cable or input jack is not damaged. Do this but plugging in some other speakers or headphones into the computer and plugging the speakers into a MP3 player or cd player.

2. check device manager. This can be done in Win XP by right clicking my computer, properties, hardware, then click device manager. Alternative way to enter device manager is by clicking start menu, control panel, system (performance and maintenance), hardware then device manager.

In the deice manager window see if any question marks or exclamation points are visible.

If so, see if it the mark is for an audio device.

If it is an audio device, uninstall the device.

Next, try to install the sound card driver again. If that fails, the enter the device manager and uninstall the sound card again, restart the PC, ignore the hardware manager, and try to install the sound card driver software again.

3. If the sound card is a separate discrete card then you can power down the PC (do powerdrain procedure to drain capactors) and reseat the sound card.
Hopefully some of this helps
