di1 DIRECT BOX
Controls
Attenuation Switch
The attenuation switch allows an incoming source signal to be attenuated by 20 dB or 40 dB. This is useful for operation with
very hot signals that would otherwise overload the di1.
Ground Lift Switch
The Ground lift switch enables or disables continuous connection of the input and output ground connection. This is useful for
helping to eliminate ground loop hum problems that can arise between connected devices. When this switch is in the down
position, the ground lift is enabled and no ground connection is made between the incoming and output signal.
