My board (Mackie 1604 VLZ III) has phantom power which the girl singer needs for her microphone. My bass amp (G-K 1001 RB II) can't have phantom power, according to the manual. For this reason I can't line out from the head to the board. Can I safely use a Radial JDI between my bass & the amp to DI to the board without any consideration for the phantom power? In other words, will the JDI isolate the bass amp from the board's phantom power?
