It features the TDA7379 power amplifier chip and an NE5532 preamplifier stage, making it suitable for speaker systems, DIY audio builds, and custom electronics projects.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I adjust the gain on this amplifier board?\u003c\/h4\u003e\n\u003cp\u003eA: Gain is controlled by resistors R8 and R10 on the board. The default configuration provides approximately 2–3× magnification. To increase or decrease the gain, replace these resistors with values ranging from 10kΩ to 47kΩ — a higher resistance value produces a higher gain factor. The board also supports plug-in resistors, so the original chip resistors can be removed and new values soldered into the plug-in pads on the patch end.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply does this amplifier board require?\u003c\/h4\u003e\n\u003cp\u003eA: This board operates on a standard DC 12V power supply, which is widely available and easy to source. Ensure your power supply can deliver sufficient current to support the 39W + 39W output capacity for optimal performance.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What type of projects is this amplifier board best suited for?\u003c\/h4\u003e\n\u003cp\u003eA: This board is ideal for DIY speaker builds, desktop audio amplifiers, car audio modifications, custom home theater components, and any electronics project requiring a compact, adjustable stereo power amplifier with a clean preamplifier stage.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are the coupling capacitors on the preamplifier stage high quality?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The input and output coupling capacitors on the NE5532 preamplifier stage use imported electrolytic capacitors, which provide superior performance compared to standard polarity-sensitive alternatives, contributing to cleaner signal handling throughout the audio chain.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does the TDA7379 Stereo Power Amplifier Board Module do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The TDA7379 Stereo Power Amplifier Board Module amplifies an audio input signal to deliver 39W + 39W stereo output using a DC 12V power supply.
