-Platform preparations
1)Ensure that all external power sources are set to OFF and that the platform power switch S1 is set to OFF.
2)Install a TPA2008D2 module in platform socket U2, taking care to align the module pins correctly.
3)Use switch S2 to select or bypass the signal conditioning EVM (U1).
4)Set control signal Polarity jumper JP8 to Lo.
5)Set jumper JP6 to select the Mute control input (causes the TPA2008D2 to shut down if a plug is inserted into platform headphone jack J10).
6)If a headphone amplifier will be installed in U5, set the headphone source switch S3 to U5.

-Power supply
7)Select and connect the power supply (ensure power supply is set to OFF ):
a)Connect an external regulated power supply set to 5 V to platform VDD power input connector J6 taking care to observe marked polarity,
or
b)Install a voltage regulator EVM (SLVP097 or equiv.) in platform socket
U6. Connect a
guide). If using J1, J2, or B1, set S1 to ON to supply power to the EVM.
-Inputs and outputs
8)Ensure that the audio signal source level is set to minimum.
9)Connect the audio source to left and right RCA phono jacks J3 and J5 or stereo miniature phone jack J4.
10)Connect speakers to left and right RCA jacks J7 and J9 or to stripped wire speaker connectors J8.
