XR18 phantom power

New
2021-07-26

Hi,


I have a Behringer XR18 and phantom power has stopped working on all channels apart from channels 1 and 9.  Anyone know what might cause this?  I'm hoping the board layout may be such that a link / ribbon cable has come loose but would like some more info before dismantling.  Is there a service manual available?


Many thanks,


Ray
