11)To have the module amplifier IC enter the shutdown mode when the module mute control input is activated, set shutdown jumper S1 to ON. To have the amplifier IC only mute when the module mute control input is activated, set shutdown jumper S1 to OFF.

12)To select the line inputs, set input select jumper S3 to OFF. To select the headphone inputs, set input select jumper S3 to ON.

13)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 S4 to OFF. To keep the module amplifier IC in the single-ended output mode regardless of the control input state, set jumper S4 to ON.

14)Set VDD bridge jumper S5 to either ON or OFF for normal operation.

15)To automatically select the headphone inputs when the single-ended output mode is selected by the module SE/BTL control input, set autosense control jumper S6 to ON. To isolate the amplifier IC input select pin from the module output mode select control input, set autosense control jumper S6 to OFF.

16)Set junction temperature measurement jumper S8 to OFF for normal operation.

17)Verify correct voltage and input polarity and set the external power supply

to ON. If VCC and an on-board regulator EVM are used to provide VDD, set platform power switch S1 to ON.

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

18) Adjust the signal source level as needed.
