Your re-labelling of Vm1 and Vm1 is not equivalent to yours so you should not change them. These are midpoints for DC near the mid point of. The uF output capacitors that feed the power amplifier pass frequencies down to 20Hz when the input impedance of the power amplifier is.

Checked the connections oksoldering, and wiring several times and is exactly the same like the example.

The capacitors are only there to decouple inputs and outputs, right? I have also some doubts about the pin order because mostly, the 5th pin is the upper-right pin. When using uf and uf there is no difference in sound quality and provides rich bass, so I think uf could be right. Skip to main content.

However when I change the output caps, tried 10uf, 22uf, 47uf, uf and uf. Perform some causal exploring. There is even more confusion when I found the “evaluation board manual”, it is practacly the same as the example in the datasheet however there are some resistors in serie on the input path with jumper pads to be able to bypass the resistor.
