Roland Octacapture problem.
« on: January 25, 2021, 01:10:19 PM »

I have a Roland Octacapture that has lost phantom power on input 2.
Works with dynamic mics and line sources, but not with any of my measurement mics.
Has anybody here experienced something like this and know if it can be fixed?

I filed a support request with Roland, waiting for their answer...

No, not yet. I guess it could be as simple as a bad connection on the output since phantom works on the other channels. Maybe I could get lucky and locate it with a DVM.

Different from the one on the front panel?
I rarely use the control panel, usually operate it from the front panel. I have tested turning phantom on/off on all channels, works as it should on all ch except #2.

I had a look inside with a DVM. There is connection from the xlr connector down to the circuit board, and the solder points look okay, so the chassis connector is probably okay. But I'm not getting phantom on the pins on input #2 so I suspect it's a component failure on the board.
It's beyond my skills and tools to repair something on a SMD board, I guess #2 just became "upgraded" to my ref input.

Where?

There is one per input in the controller and on the front panel, AFAIKWO they appear to do the same thing when I operate them.
