13)Verify correct voltage and input polarity and set the external power supply and platform power switch S1 to ON.

Note:

Platform LED1 should light indicating the presence of VCC, and the evalua- tion module(s) installed on the platform should begin operation.

14)Set switch S2 to ON if tone control board SLOP109 is installed in U1.

15)Adjust the signal source level as needed.

2.4Quick Start List for Stand-Alone Operation

Follow these steps to use the TPA3001D1EVM as a stand-alone unit, or when connecting it into existing circuits or equipment. Connections to the TPA3001D1 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.

Power Supply

1)Ensure that all external power sources are set to OFF.

2)Connect an external regulated power supply set from 8 V to 18 V to the module VCC and GND pins taking care to observe marked polarity. It is only necessary to use the ground pins adjacent to the module power pins.

Inputs and Outputs

3)Ensure that audio signal source level adjustments are set to minimum.

4)Connect the audio source across the module IN+ and IN– pins, taking care to observe marked polarity. For single-ended input, the negative input pin (IN–) should be connected to the ground of the audio signal source.

5)Connect a speaker to the module OUT+ and OUT– pins, taking care to observe marked polarity.
