Frequently Asked Questions
Q: What type of microphone is compatible with this amplifier board?
A: This condenser microphone preamp amplifier board is designed specifically for electret microphone capsules — both universal and single-point types. It is not intended for dynamic microphones. For the cleanest audio output, use a low-noise electret capsule.
Q: What phantom power voltage does this board require?
A: The board accepts a wide phantom power range of 15V to 48V. Standard 48V phantom power (provided by most audio interfaces and mixers) works perfectly, as do lower-voltage phantom power sources from 15V and up.
Q: Can I use this board for home recording and studio applications?
A: Yes! This amplifier board is well-suited for DIY home recording microphone builds, as well as karaoke systems, conference setups, and speech applications. By pairing it with a quality low-noise electret capsule, you can achieve a clean, professional-sounding signal with a 60dB signal-to-noise ratio and 125dB SPL handling.
Q: What are the dimensions of the board?
A: The board measures 45mm × 16mm (approximately 1.77in × 0.63in), not including any attached microphone head. Its compact size makes it easy to fit inside custom microphone enclosures for DIY builds.
