I added one filter IC for the E-amp channel, I soldered J0, but I don't see the extra filters menu... What am I doing wrong?

You may have to update the firmware.

Older versions did not have filter menu.

Hi Kevin,

Thank you for your reply. I am already on the latest beta firmware of System Blue, 8.1, but no luck yet.

If you installed the filters correctly and jumped J0, you should be seeing the filter option for channels you have set to normal.

Maybe you can take picture of circuit board?

Do I have to solder IC's for all 4 channels? Currently I'm only using the E-amp, because I'm in the process of making my H-field antenna's. So I only soldered the IC for the E-amp... I disabled the H-amps in the config.

No, there is an information somewhere in the manuals that you should start with one IC and then check if it was succesfully and if it helps.

I did not solder my 2 chips at the moment but I don't need more.

They can be mounted in random order and from one to four pieces.
The CPU tests J0, it is shorted, it sends clock signals, filter-ic or not Smile

Looks correct.

Could be jumper is bad, or a defect with the board.

RichoAnd what happens with the CPU connection is floating?

Hi everybody,

I have to apologize, the filter section is only visible when Remote Control mode is set Manual mode. I found it by accident... Sorry for the confusion...

I was just going to post that. Tongue

I was getting interference and testing automatic and noticed filters were gone.
