When your Soundbridge Network Music Player (models m500/m1000/m1001/m200) seems to not be receiving power, it is most likely an issue with your Power Adapter. Using a multimeter, you can test to see if the power adapter is working properly. This test MUST be done with the unit under a load, as testing without a load will usually show a proper voltage reading, but once a load is attached, the unit will be shown to be failing.

Testing the Soundbridge's power adapter with a load attached can be done in various ways:
1) you can take the unit to your nearest Radio Shack (or other electronics store) and ask the employees to test the adapter with a load attached.
2) you can hook up the soundbridge up to the adapter, and then using the tips of the multimeter probes to carefully pierce through the plastic covering protecting the wires to get a reading (make sure not to cross the probes.)

If you have a m1001 or M400x unit AND a Roku Streaming Player, then you can test to see if the problem is the power adapter by using the adapter for the Roku Streaming Player to see if it powers you device, as the two units have interchangeable adapters (Note: The inside diameter for the Streaming Players is a touch larger than that of an m1001/m400x so the connection may be slightly loose).

All of the following information is a guide to aid you in finding a proper power adapter for your Soundbridge device, please be sure to read thoroughly:

Any power adapter that you use to operate your Soundbridge device will need to be regulated.

The following list shows the minimum requirements for a power adapter for each of the different Soundbridge devices. Voltage requirements need to be precise, while amperage requirements are the minimum needed to power the device. For best performance it is generally recommended to try to get a power adapter that has a higher amperage rating.

M2000:
24 volts, DC, center positive, 0.7 amps.
Outside diameter = 5.5mm; inside diameter = 2.1mm.

M500/M1000 (with connections under the endcaps):
9 volts, DC, center positive, 1.3A.
Outside diameter = 5.5mm; inside diameter = 2.1mm.

The M1001 (includes units labelled as M1000 but with connections at the back) and the M400 PX (aka Pinnacle HomeMusic):
5.0 volts DC @ 1500mA (or 1.5Amp) connector uses 2.1 inside diameter and 5.5mm outside diameter. Center positive.
Take care to ensure that the replacement PSU has a straight edged connector. The elbow connectors that are now common will not fit inside the recess. Ask the online webshop about this specifically, or visit the real shop. This is true of all units with the power connector in a recess. Apparently, Maplins sells the straight pin connectors separately.

For US Purchases:
You can purchase replacements for the m1001 at:

(The Roku Streaming Players power adapter, does work with the Soundbridge m1001)

Apparently, Roku has stopped selling, or ran out of stock for power adapters that will work with models other than the Soundbridge M1001, when looking for replacements for m500/m1000/m2000 models, please confirm the specs with listed in this post. (Note: I will be updating this list with options as I find them)

Special thanks to Burkhardi, S80_UK, dupondt, and jjaf for their help in compiling this information.

Edit: 9/18 updated Soundbridge accessories store URL for purchasing PSUs for m1001

Im getting this set up as a sticky, please let me know if you think I need to make any changes to this post.

Derek,

Your M2000 info is in error... The M2000 takes 24 volts DC (centre positive) and the supply must be rated to supply at least 0.7 amps.

Also I suggest that your listing for M1000 should add "(connections at the ends)" and your listing for the M1001 should include "(includes units labelled as M1000 but with connections at the back)" since Roku sold many such units.

Edit - thanks! (that was quick)

Regards,

Les.

Thanks for talking the time for such a good and useful post Derek.

This will be a helpful tool to Alanmc, Les and Dupondt that are always on the ball when it comes to helping SoundBridge owners with power supply issues on these forums (as you are too).


SOUNDBRIDGE OWNERS: for what it's worth, if your power adapter (aka Wall-Wart) checks out ok/fine and you still have a dead M500, M1000 or M2000, please contact myself or Pete before you deem the unit not salvageable. Pete and I have had great luck in regards to repairing these units. So please contact either of us before you throw in the towel so we can get your music streaming around your house again.

We can do this for a very fair price which makes this a very good and cost effective option; and since they are no longer in production and you can't beat the UI among other thigns, then it's a great option.

Note: Even if it seems dead other then a couple of the side LEDs (where the Ethernet port is located on the side (same as the side in Wi-Fi card (in CF formfactor))) we can still help.

We also can service your M1001, R1000 and HD1000

Edit - added other devices that we support.

Les, thank you for the correction, and fixed!

Matt, not a problem, and Les should also be thanked as the idea came from a post that Les made a few weeks ago and I decided to look into the possibility of this being a sticky.

Edit:
Again, I'd like to thank the two of you for your input and please, let me know if you (or anyone else) sees anything else I may have made a mistake on, I did type all of this up relatively quickly and without my soundbridges in front of me.

a) It should be made clear that the SoundBridges need regulated PSUs.

b) The amperages of the original PSUs are minimum requirements, using higher rated adapters is highly recommended.

c) You forgot the SoundBridge M400 PX (aka Pinnacle HomeMusic), which uses a PSU identical to that of the M1001. As this model has an LC display 1.5 amps should be sufficient.

dupondt,

Thank you for the suggestions, changes have been made to the original post. Additionally, if you happen to know of any good european locations for replacement adapters, Id love to know what they are so I can include them in the post.

Dupondt, Thank you for that rather comprehensive list, it has been added to the original post.


Methinks I'm going to need to clean that post up sometime soon.

Is there a power unit that we can buy in Radio Shack that will sufficiently and correctly replace the one for the M1001? Thanks

As above...

The M1001 (includes units labelled as M1000 but with connections at the back) and the M400 PX (aka Pinnacle HomeMusic):
5.0 volts DC @ 1500mA (or 1.5Amp) connector uses 2.1 inside diameter and 5.5mm outside diameter. Center positive.

That should be enough of a description to allow them to provide a suitable supply.

Note - it must be 5 volts regulated. Not 4.5, not 6, not anything but 5 volts.

Les.

What a blessing this forum has been. Without it I would have binned my M1000, but as it was I found another supply that did the trick. Thankyou.

Updated information about using straight pin style connectors for M1001 units.

In case this helps, I have had good luck replacing dead Soundbridge power supplies with 5V supplies that come with many Dlink routers (these are usually rated at 2A).

The connectors are not the same, so you have to cut the cable and rejoin the old connector--just make sure you test with a multimeter to ensure you have the polarity right. If you don't want to solder, make a good twist connection and tape it well. I mention this because sometimes older Dlink routers are on sale for a pittance--probably about the same as a decent power supply and shipping would cost. Or perhaps some of you might have one hanging around. I have two Soundbridges that have been working fine with 5V Dlink power supplies for three years or so. (I have also learned to never throw out power adapters after something dies. You never know when one will come in handy.)

As my Soundbridge M2000 or hopefully only its power-supply (no lights working, even not the ethernet lights!) has passed away yesterday, is there any possibility to get a european-version of the power-supply?

Or is there any power-supply form conrad.de which is reccommendable for the M2000.

Thank you very much for your help.

Patrick
