of the EVM is provided to monitor the dc voltage. See Table 3–1 for gain settings.

12)Adjust the SE (headphone) volume by adjusting potentiometer R6. Turning R6 in the clockwise direction decreases the voltage on the SEDIFF terminal and the SE gain increases. Turning R6 in the counter clockwise direction increases the SEDIFF voltage and decreases the SE volume.

13)Set the maximum possible SE gain by adjusting R7. Turning R7 in the clockwise direction sets the limit higher; turning R7 in the counter clockwise direction lowers the SE gain limit.
