Adjustment Methods and Notes on Operation

1) VIN Offset (VR1)

The volume to adjust the AMP. IN signal range (0V center assumed) with the A/D converter input range.

2) A/D Full Scale (VR2)

The volume to adjust A/D converter VRB voltage (–2V typ.).

3) Linearity (VR3)

The volume to adjust the VRM (linearity) voltage by shorting the J1.
