DGND

Connection pins of

resistors for setting the

recording equalizer

amplifier parameters.

∗ Current input pins

used to set the

parameters for the

recording equalizer

amplifier.

∗ Setting currents for

each parameter are

generated by

attaching resistors

between these pins

and the DGND pin.
