HUM-vee
I know I've done this setup before, but
last night had big problems...... shooting with a battery powered camera, boom mike attached via XLR adapter, and monitoring video out to a Sony monitor,which was plugged in (AC)--- the video out cable to the monitor was creating the dreaded 'hum'...remove the cable from the jack, hum gone does this mean I HAVE to run my external monitor off a battery as well? |
Use an isolation device or a ground-lifter.

Mike,
Where do you find an isolation device or ground lifter? Do you use any specific one? Thanks... |

Of course this one is a 1/4 inch jack I/O but with adapters it will do the job. I always carry one around if I am plugging into someone elses board. |
Also, search around TecNec (www.tecnec.com), They have a bunch of different Ground-loop and Hum eliminators in their catalog, and i'm sure on their website as well.
