M3 DI problems

Post by justplay » Sun Jun 24, 2012 7:52 pm

Hi, we are having an issue with the our Mesa m3 Carbine rack amp. This amp is being fed into a Hartke HyDrive 4x10 cabinet. There are no other effects of sorts conected, just the amp head and the cab.

When trying to DI the bass from the head to the mixer board ( Mackie CFXII-16 ) with an XLR cord into one of the channels on the board, we get nothing but a hum. Even with the gain turned all the way off on the mixer channel and the volume and gain controls on the amp fully down, the mixers master channel is still showing noise on the master mixer channel lights. Is there a step we're missing, or does this sound like a defect? The amp seems to work ok without the DI socket connected.
