Hi,
I have an old bluetooth headset circuit that has no functional speakers and a home theater with damaged input ports.
I managed to open up the home theater driver amp and directly connected the bluetooth headset circuit to it via wires and some soldering.
Now, my problem is that whenever I switch on the home theater and the bluetooth headset, the home theater starts making weird noises. I am guessing it's because of the battery in the headset that provides some sort of voltage to the amp.
Is there anyway to get this set up functional and eliminate the noise?
Thanks.
 
Solution
If the BT receiver is battery powered that shouldn't put any noise into the HTS. Did you test it into a known working input on another system
You assumed the problem is somewhere downstream of where you connected the BT receiver? Might not be.
