11)To allow the module SE/BTL control input to switch the amplifier IC between single ended (SE) and bridge-tied load (BTL) output modes, set output mode jumper J1 to OFF. To keep the module amplifier IC in the single-ended output mode regardless of the control input state, set jumper J1 to ON.

12)To allow the module HP/LINE control input to switch the amplifier IC between using the HP pins and the LINE pins as the signal inputs, set the input mode jumper J2 to OFF. To keep the amplifier IC in the HP input mode regardless of the control input state, set jumper J2 to ON.

13)To allow the amplifier IC to switch from the LINE inputs to the HP inputs when the output switches from BTL output mode to SE output mode and vice versa, set jumper J3 to ON. To allow the inputs and output modes to switch independently, set jumper J3 to OFF. Jumper J3 ties the HP/LINE and SE/BTL pins together on the EVM.

14)To place the amplifier in FADE mode, install jumper J4. FADE mode slowly ramps up or down the gain of the amplifier when leaving or entering SHUT- DOWN mode.

-Power Up

Platform LED2 should light indicating the presence of VDD, and the evaluation modules installed on the platform should begin operation.

15)Adjust the signal source level as needed.

16)Adjust the BTL (speaker) volume as needed by turning the R5 potentiome- ter in the clockwise direction to increase the volume. Turn in the counter clockwise direction to decrease the volume. The VOL pin on the right side of the EVM is provided to monitor the dc voltage. See Table 3–1 for gain settings.
