This dual-mode input connector is a balanced 
XLR-3-31 type.
The INPUT1 connector can be set for two types of 
input: when the sensitivity switch (

C

) is set to 

MIC microphone-level signals can be connected 
directly to the input; when the sensitivity switch 
(

C

) is set to LINE the input accepts line-level sig-

nals such as those from a preamplifier or mixer.

Use this switch to set the sensitivity of the 
INPUT1 connector to match MIC (microphone-
level) or LINE (line-level) input signals.

The INPUT2 and INPUT3 connectors are unbal-
anced phone jacks for direct connection of line-
level audio signals and musical instruments.
