Frequently Asked Questions
Q: What is a digital amplifier board and how does it work?
A: A digital amplifier board (commonly Class D) converts an audio input signal into a high-efficiency amplified output using pulse-width modulation (PWM). Unlike traditional Class A/B amplifiers, digital amp boards like the TPA3116 or TDA7293/7294-based modules generate less heat and are more energy-efficient, making them ideal for compact DIY speaker builds and home audio systems.
Q: What power supply do I need for these amplifier boards?
A: Power requirements vary by board. Most of our digital amplifier boards operate on DC voltages ranging from 12V to 36V. For example, the 100W TPA3116 Mono Digital Amplifier Board runs on DC 12–24V. Always check the individual product specifications and pair your board with a regulated DC power supply that meets or slightly exceeds the rated voltage and current requirements.
Q: Can I use these amplifier boards for a subwoofer setup?
A: Yes! Several boards in our collection are specifically designed or well-suited for subwoofer applications. The 100W Dual Channel Digital Power Amplifier Board and the 100W TPA3116 Mono Digital Amplifier Board both support subwoofer configurations. Pair them with one of our subwoofer speaker drivers for a complete bass system.
Q: Do I need soldering skills to use these boards?
A: Many of our boards come pre-assembled and only require terminal connections — no soldering needed. For example, our 120W 4-Way Solderless Crossover Module is designed for tool-free installation. However, some DIY speaker modules may require basic soldering for wiring, so we recommend reviewing individual product descriptions before purchasing.
Q: What is a crossover module and do I need one for my speaker build?
A: A crossover module splits an audio signal into different frequency ranges (bass, mid, treble) and routes each range to the appropriate speaker driver (woofer, midrange, tweeter). If you're building a multi-driver speaker system, a crossover is essential for accurate, balanced sound reproduction. Our 120W 4-Way Solderless Crossover Module is a great plug-and-play option for DIY home speaker projects.
