Hardware Connection

This section introduces a simple connection method for the NT-NAU82011V as Figure shows the audio signal path of NT-NAU82011V.

1. Connect the audio signal to J1 of the NT-NAU82011V, and connect the speaker to J2 and J3 of the NT-NAU82011V.
2. Connect the rated power to J4 and J5 of the NT-NAU82011V.

Gain setting

NAU82011V has a provision for variable gain setting by using external input resistors. The gain is expressed as the ratio of the internal feedback resistor of 300kΩ and the external input resistor R. The Gain is expressed as

Users can adjust the output gain by changing R1 and R2 on the NT-NAU82011V, as shown in Figure R1 and R2 are set to 150kΩ by default, resulting in a default gain of 6 dB for the NT-NAU82011V.
