Audio Settings:
Phantom Power (+48V): This setting determines whether phantom power (+48V) is enabled (On)
or disabled (Off) for all four Inputs.
Important: Only enable phantom power if your microphone requires it. Most dynamic
microphones and ribbon microphones do not require phantom power, while most condenser
microphones do. Consult your microphone's documentation to find out whether it needs
phantom power.
XLR Ground Lift: This setting determines whether the XLR ground lift feature is enabled (On) or
disabled (Off). Use this feature to reduce hum or noise in the signal from the XLR Outputs.
1/4 Output Level: This setting determines the output level of the 1/4" Outputs. When set to
Line, the output level will be +18 dBu. Use this setting if you are connecting HeadRush
Looperboard to a full-range, flat-response amplifier, PA speaker, mixer or audio interface. When
set to Amp, the output level will be +6 dBu. Use this setting if you are connecting the
HeadRush Looperboard to a traditional guitar amplifier.
