What is the GRND / GND switch used for

Question:

What is the GRND / GND switch used for on my Helicon product?

Answer:

This is referred to as a ground lift. The purpose of the ground lift switch is to overcome buzzing that may occur when the Thru jack connects to a different amplifier/PA. Leave out when Thru is not connected.

This issue typically happens when you have the Helicon unit on the different power circuit from what the thru is being plugged into.
