8. INPUT 1~6 JACK AND INPUT SELECTION SWITCH
INPUT 1~6 are utilized to connect various external sound source devices including MIC, CD, TUNER, etc
1) INPUT 1~3 (Balanced XLR JACK) AND INPUT SELECTION SWITCH
LINE: It can be used as LINE level signal input.
MIC: It can be used as the normal dynamic MIC input.
PHANTOM: It can be used as the condenser MIC input and DC 24V is supplied to the input terminal.
2) INPUT 4~5 (Balanced 6.3Ø Phone JACK) AND INPUT SELECTION SWITCH
LINE: It can be used as LINE level signal input.
