Questions answered in V-TONE manuals
How do I turn the ADI21 on and off?
The unit powers on automatically when a plug is inserted into the INPUT jack and powers off when the plug is removed; there is no separate ON/OFF switch.
What does the GND LIFT switch do?
When activated, GND LIFT disconnects the ground connection between input and output to reduce hum and other noise.
