Ipad and vga adaptor and PA system
I have aHarbinger110 PA system and have mics, guitars, and ipad plugged in - all works great. But...
When I want to send Visio to the tv and sound to the PA, I get a hum. Read about ground loops and unplugged everything, used same surge-protector and get the hum. Even swapped vga cable for a shielded one. The hum only starts when I plug the vga adaptor into the ipad.
PA------ipad (earphone port). Great sound
PA------ipad (earphone port)----dock-jack--vga-adaptor----cable---tv (hum)
If you want to split audio and video, you have to use vga adaptor.
Checked for noise gate app but could not find anything. Any ideas on options?
