Hi All,

Hope you guys are doing fine. I have searched all over the internet and no proper solution i have come across. So i hope someone may help me out here.

I have this Philips Fidelio wireless Subwoofer (Model:B5) It is a part of a wireless system. The main unit is giving problems and so i couldn't use the subwoofer. i have opened the panel and the pictures are as per link below:

From what i gather, the boards have been separated into 2 parts: 1 is for transformer; and 2. for the amplifier. The unit is working is fine. I can't figure out there is the stereo in on the amplifier board. If you look closely, the rectangular shape metal piece is actually the bluetooth module to connect. i used my phone to search the sub, and it is discoverable but i couldn't pair the sub with my phone. I have also included in greater detail on the 'bluetooth chipset'. I am no engineer so i would know where or how to connect my 'line in' into the amplifier.

The amplifier is good and because of that, i would like to use it. There are cheap amplifiers around (TPA3116) but if possible, i would like to use the internal one.

I hope someone could help me out by showing me where or how to hook up the 'line in' into the current amplifier. Hope to hear from you guys soon.

Thanks in advance

If you can find out which pins of the (WI-FI?) plug-in-board are the Left & right audio signals output, I think you could connect to those (amplifier) inputs the line-out of your PC, TV or other device.

What is written next to the 4-pin white socket at the right site of the base-board?

Hi Sluc,

Thanks for replying to my thread. First of all, the wireless connection is bluetooth, and the bluetooth module is connected to the board by 26 pin (nex to CN204, where you can see 1 on top, and 2 below, right until the end, where it has written 25 on top and 26 at the bottom - Img no.222711). So there is no left or right signal output.

The 4 pin white socket at the right hand side. This one connects the bluetooth button as well as LED notification for the connection. it does not show the input of any sort of line in.

Top right has 6 pins, and it does not state any 'signal in'.

Any other possibility? I was thinking what is the A & B on the bluetooth module? is that some kind of antenna to receive the audio? do you tink that can be used as 'line in'? i have not tried it yet..

Hope to hear from you soon. Thanks for replying and helping out... :-)
