Comment
(1)
J2, J3 (MINI-JACK)
J2 : It is analog signal input Jack. The signal is input to LIN1 / RIN1 pins.
J3 : It is analog signal output Jack. The signal is output from LOUT2 / ROUT2 pins, and JP17, JP19 should be
“short”.
(2)
J1, J4, J5, J7, J9, J11 (BNC-Connector)
J1 : It is analog signal output Jack. The signal is output from LOUT pin.
J4 : It is analog signal output Jack. The signal is output from ROUT pin.
J5 : It is analog signal input Jack. The signal is input to LIN2 or LIN3 or LIN4 pins, and JP23 should be selected.
J7 : It is analog signal input Jack. The signal is input to RIN2 or RIN3 or RIN4 pins, and JP25 should be selected.
J9 : It is analog signal input Jack. The signal is input to SAIN1 or SAIN2 or SAIN3 pins, and JP28 should be selected.
J11: It is analog signal input Jack. The signal is input to SAIN3 pin.
