11) Use potentiometer R3 to set the volume. Turning R3 in the clockwise
direction will increase the volume. See Table 3–1 for voltage levels on the
VOLUME pin and corresponding gain settings.
12) If using an external DAC, adjust R3 to the center position by placing a
DMM across the VOLUME pin and ground and adjusting the
potentiometer until 25 kΩ is measured across the leads. Apply the external
source to the VOLUME pin.

- Power Up
13) Verify correct voltage and input polarity and set the external power supply
to ON. If V
CC
and an on-board 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 and potentiometer R3 as needed.
2.3 Quick Start List for Stand-Alone
Follow these steps to use the TPA2008D2 EVM stand-alone or when
connecting it into existing circuits or equipment. Connections to the
TPA2008D2 module header pins can be made via individual sockets,
wire-wrapping, or soldering to the pins, either on the top or the bottom of the
module circuit board. Numbered callouts for selected steps are shown in
Figure 2–3.
