Frequently Asked Questions

Q: What power adapter do I need for the Stereo Bluetooth Amplifier Board?

A: This amplifier board accepts a wide input voltage range of 8–26V DC. You can use any compatible DC power adapter within this voltage range. For best performance at 2×25W output, a higher-current adapter (e.g. 24V/3A or higher) is recommended to ensure stable audio delivery to your passive speakers.

Q: Can I use this Bluetooth amplifier board with existing passive bookshelf speakers?

A: Yes! This module is specifically designed for use with passive speaker cabinets. Simply wire your passive speakers to the green terminal block outputs, connect a suitable DC power adapter, and pair your Bluetooth-enabled device to stream audio wirelessly with full stereo amplification.

Q: How compact is this amplifier board — will it fit inside a desktop speaker enclosure?

A: The board measures approximately 8.20 × 5.00 × 1.80 cm (3.23 × 1.97 × 0.71 in), making it well-suited for tight desktop enclosures, custom cabinet builds, and other space-limited DIY audio projects where a full-sized amplifier would not fit.
