ON = Shunt installed, OFF = Open
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) When the module powers up or comes out of shutdown, the volume is set
at the –85 dB level. Press the UP pushbutton, S2, until the desired volume
level is reached.

Power Up
13) Verify correct voltage and input polarity and set the external power supply
to
ON. If V
CC
and an onboard regulator EVM are used to provide V
DD
, set
platform power switch S1 to
ON.
Platform LED2 should light indicating the presence of V
DD
, and the evaluation
modules installed on the platform should begin operation.
14) Adjust the signal source level as needed.
