DAMGOO T300HS 2.0-Channel Amplifier Board with Bass & Treble

DAMGOO T300HS is a compact 2.0-channel amplifier board powered by the TPA3255 chip with independent bass and treble controls, Bluetooth/AUX/USB inputs, and DC 9–24V compatibility for DIY wireless speaker builds.

This amplifier board is designed for hobbyists and professional DIYers who want studio-grade dynamics and flexible connectivity in a small package. The TPA3255 class-D amplifier offers high efficiency and headroom, while the onboard bass and treble pots allow quick tonal tweaks without an external equalizer. It supports Bluetooth streaming without a pairing password, direct USB audio playback (MP3, WAV, APE, FLAC), and a standard 3.5mm AUX input for legacy devices.

How much power and sound quality can I expect from the T300HS?

The board uses the TPA3255 amplifier topology to deliver high-efficiency output and clean transient response, enabling loud playback with reduced thermal stress. It’s rated to deliver substantial wattage per channel when supplied with the appropriate DC source, giving clear detail at both low and high volumes.

• TPA3255-based class-D amplification for efficiency and headroom
• Designed to support high output levels with controlled distortion
• Independent treble and bass controls for on-board tone shaping

What inputs and file types does the board accept for playback?

Connectivity is broad: wireless streaming via Bluetooth (password free for fast pairing), a USB port that plays common digital audio files directly from a flash drive, and a 3.5mm AUX jack for wired sources. That makes the T300HS a flexible hub for smartphones, PCs, media sticks, and older audio gear.

• Bluetooth streaming with simple password-free pairing
• USB playback supporting MP3, WAV, APE, FLAC file formats
• Standard 3.5mm AUX input for analog connections

How easy is it to integrate the board into a DIY speaker or existing system?

The PCB includes pre-drilled mounting holes and a removable panel for clean cable routing and flush installation, making it straightforward to mount into cabinets or enclosures. Terminal blocks and labeled connectors simplify wiring for power, speakers, and inputs, so minimal soldering is required for most builds.

• Pre-drilled mounting holes for quick installation
• Removable panel for tidy cable access and placement
• Labeled connectors and terminal blocks for easy wiring

What power does the board need and how should I match it with speakers?

The T300HS accepts a DC supply between 9 and 24 volts; the voltage you choose affects maximum available output and efficiency. Pair the board with speakers whose power handling and impedance match your chosen supply to avoid clipping or overheating at high volumes.

• Compatible with DC 9–24V power supplies
• Higher supply voltage yields more headroom—match to speaker specs
• Recommended to use properly rated power supply and cooling

Who is this for: The DAMGOO T300HS suits makers building custom Bluetooth speakers, audio hobbyists upgrading passive speaker systems, educators creating demo rigs, and small-scale installers who need a compact, tone-adjustable amplifier board. It’s especially useful when you want a balance of raw output capability, easy source switching (Bluetooth/USB/AUX), and straightforward integration into cabinets or projects without complex setup.
