"XLR Outputs are not affected by 48V phantom power."

Recommended Posts

I own a PC212+.  Page 7 of the user manual says:

"NOTE: XLR Outputs are not affected by 48V phantom power."

 

Anyone know the difference in architecture between the PC112+/212+, and Helix, which says:  "IMPORTANT! Never connect the Helix device's XLR outputs to a device whose XLR inputs have 48V phantom power enabled!"

 

I was about to purchase a 2-channel Line Isolator for my PC212+ plugging into FOH mixers until I realized it lacked the same warning as the Helix.  Would the Line Isolator have no affect whatsoever, or would there still be some benefit?

The Helix XLR outs won't be damaged by phantom power, but phantom power can attenuate their output and/or make them sound bad. This is because of the anti-pop circuitry on those outputs. Apparently the Powercab XLR outs don't have this anti-pop feature. There's probably no reason to use a line isolator with the PC.
