Newbie and first post so be nice!
I have a problem with a high pitched interference when on phantom power.
I have a Tascam US 600 and a selection of new and second hand mics. My aim is to record stage shows, so to that end I own three Stageline Em925p's rifle/shotgun mics. These can be either phantom or battery powered. I also inherited a Philips LBB 9510/20 which looks like a dynamic mic but is a condenser so needs phantom.
The issue I have is that the stageline's have a faint but audible whine when connected and phantom powered (on battery there's no whine). Made me think a problem with phantom from the unit. However, connecting the Philips there's no whine when on phantom.
Whilst I can run on battery to solve the problem (rather use phantom though) I'm eager to learn if this just a case of budget mics or is there something else going on that I could solve.
Have tried to eliminate poss sources such as -
- tascam unit connected/not connected to PC - no change
- all PC's/gadets unplugged from power supplies throughout the house - no change
- Mobile phones switched off etc - no change
- Different xlr leads - no change
- I have no fluorescent lights in the house
Any theories......?
Many thanks
Gary
