Hi there,
I need to connect the audio signal coming from this BT module (BT.PDF) to the
WM8783 (we need to use that device for its low cost!)
I undertand about DC blocking capacitor (I intend to use ~1uF). The problem is that the BT module outputs 3 signals:
- Right
- Left
- AOM (Audio ouput comon, which is fixed at 0.9V, and should not be grounded!)
The WM8783, on the other hand, has only 2 inputs:
- Right
- Left
What is the best way to connect both devices?
Should i just ignore the audio output common (AOM)?
Here is what i intend to do, simply:
(MOD 2 is the BT module)
Should i put some voltage divider before the DC blocking caps, in case i need to decrease signal amplitude?
Are there some rule of thumbs i should consider or some advice you could share ?
Thanks a lot in advance.
