11)To allow the module SE/BTL control input to switch the amplifier IC between single ended (SE) and
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 S3 to OFF. To keep the amplifier IC in the HP input mode regardless of the control input state, set jumper S3 to ON.
-Power Up
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 S4 to ON. To allow the inputs and output modes to switch independently, set jumper S4 to OFF.
Platform LED2 should light indicating the presence of VDD, and the evaluation modules installed on the platform should begin operation.
14) Adjust the signal source level as needed.
