In default configuration, R171 and R172 are already populated

(Default)

Through Amplifier (Not

J16

It is an alternative input for channel 8. Need to install two resistors (R169 and

Default)

R170) and remove two resistors(R171 and R172) from J6.It uses TI THS4509
single-ended to differential amplifier.
