BeoSound 3 only supports SD cards up to 2 GB in size from SanDisk. BeoSound 4 (mk. II) supports SD cards up 16 GB.

I have the Beosound 4 (mk. II) using different SanDisk SD cards at 2 GB / 4 GB / 8 GB without any hiss. I am using my PC and Windows Media Player with 192 Kbps for "recording" the tracks.

Try to format the card and then save some new songs into a folder from your PC.

I've tried formatting several times and added different songs and it still doesn't work. The SD card I use is from SanDisk and is 2GB a higher speed version of 15 MB/s called "Ultra II" but don't see why a faster card should cause any issues?

I have also tried with a non-SanDisk SD card of conventional speed and 512MB but not of the brand SanDisk and I get the same hiss sound.

I can convert new MP3 songs but if the product is soo sensitive to formats etc (and the songs I have added to the SD cards comply with the specifications) it is an odd product. I might have a faulty unit - what a shame.

Well - You might have a faulty unit - I dont think this hiss is normal on Beosound 3. On Beosound 4 i dont have any noise of any kind when playing SD card.

It must be other members who has Beosound 3 and can help you! Or try the Bang & Olufsen homepage:

Sorry for being obvious, but do these MP3's sound OK on other kit than your BS3?

Hi, yes they are fine on other units. I've simply dragged-and-dropped them from iTunes to the SD card (Mac).

Have sent an email to B&O customer service - let's se if they can cast some light on this. Will post here if useful info from them.

Thanks for your input.

Are these downloaded MP3's or something you have encodec yourself - if so, what did you use to encode them?

Hi, I encode them myself from CD's using iTunes (I have a Mac computer if that makes a difference). I have just ordered a conventional slow speed 2GB SD card of the brand SanDisk which I understand B&O recommends so will se if it makes a difference.

I have 2 BS3's and I don't recall either making a hiss noise like you describe. 🙁  I've used many different sized cards and speeds over the years.  I would guess it needs a repair, or (if repair costs are similar to other B&O costs) learn to deal with it 🙂
