View Full Version : Crackle on speakers

I have a second hand SliMP3 player and have been very impressed with it's ease of use. However, one set of speakers is currently on their way back to the manufacturer only for me to find that there was still a problem with alternative speakers. The problem is intermittent, which is why the speakers got as far as being sent back, but I can now confirm that the problem is with the SliMP3 box. I have the output splitting. One split goes to an amp and speakers in the front room. One split goes to some powered speakers in the kitchen. When the nasty crackling starts, it's on both sets of speakers and also remains if I plug in one set at a time.

Through experimentation this morning, it seems that I can stop the cracking (for now at least) by having the volume around the half way mark. This isn't the worse thing in the world, but does render the volume control on the SliMP3 remote pretty useless. If the volume goes up to about 3/4, then this crackling starts to occur intermittently.

Has anyone else noticed this problem? Is there anything that can be done about it?

Cheers
Damian

No feedback on this? Is it a problem with my device? Is it fixable?

It sounds like a HW problem to me. I know nothing though.

There have been reports of some soldered joints corroding inside the older
SliMP3 devices. If you are handy with a soldering iron or just want to give
it a shot, open up the case and look for any signs of corrosion.

My uneducated guess is that cranking up the volume on the Squeezebox you are
exceeding the limits of the DAC. When you do that, the analog output will
have some very sharp edges.

You could confirm that by looking at the analog outputs with an
oscilloscope, something that most people do not have.

Are you using RCA or 1/8" jack out?

I'm using RCA and then using a splitter to 2 different sets of speakers.

It sounds the same if I remove the splitter though so that's not the trouble.

I'll maybe have a look for dry joints someday, but I'm not the best with a soldering iron.

In the mean time, I just need to keep the volume at about half way. Works ok, just feels like I've got a second rate piece of kit.

check for loose connections first ...though you may have a dry joint in a cable ....

I have heard pops and crackels from an sb3 when the pc's transmitter was trying to do too many things.

I've wiggled all the connections and tried different sets of speakers. I'm pretty sure the server computer has been pretty idle too other than serving the SliMP3 when this has happened.

Interesting Problem. Does the SliMP3 have an analogue or digital volume control(like the SB3)? If It's analogue, just replace the SliMP3 with some other audio source and crank it up. If the crackling occurs, it's probably in your splitter hardware or down in that level. If not, the player is probably at fault.

For the record, SliMP3 only has analog RCA and 1/8" headphone jack outs.
