Powerful, clean sound for your DIY audio projects

The Hosyond 200W Bluetooth 5.0 Amplifier Board brings robust, high-fidelity amplification to your passive speakers. Built around the TPA3116D2 with an AM interference suppression function, it aims for precise audio reproduction even during prolonged high-power operation.

Key features at a glance

• Low distortion under load: THD stays below 0.1% at higher power for clearer highs and tighter bass.
• Dual-channel power: 100W per channel, suitable for 4–8 Ω speakers and compact home setups.
• Flexible power and impedance: operates from 5–24V DC; ideal for 4–8 Ω systems; best results with 50–100W speakers.
• Two input options: 3.5 mm wired input and Bluetooth 5.0, with wireless reach up to ~49 feet for easy streaming.
• Stable, lasting performance: 5 × 470 µF capacitors and a large cooling system support long listening sessions without undue heat buildup.
• Safety first: reverse, overvoltage, undervoltage, overheat, and short-circuit protections for worry-free use.

Real-world use and scenarios

Compact enough for desktop setups and rugged enough for living rooms, home theaters, or DIY speaker projects. The combination of Bluetooth input and wired 3.5 mm makes it flexible for streaming music from a phone, tablet, or media player, while the strong 100W+100W output powers modest-sized enclosures with clarity and presence.

Typical applications include introducing sound to DIY passive speakers in a home theater, creating a music corner in a workshop, or upgrading a compact outdoor audio system. The board’s protections and heat management help maintain steady sound output across sessions, giving you more control over your listening experience.

What to know when pairing and installing

For best results, use a power supply within the 12 V range and supply capable of at least 5 A. Pair with 50–100W speakers for a balanced, engaging sound profile. The design supports safe operation in typical home environments and can be integrated into a range of enclosures or chassis.
