XHA310 4 channel Bluetooth 5.0 power amplifier board Product model: XHA310 Overview The XHA310 is a four channel Bluetooth 5.0 amplifier board built around the TPA3116 digital power amplifier. It delivers four amplified outputs with a combined power profile of 50Wx2 + 100Wx2, enabling flexible 4channel sound and dualsubwoofer configurations for home theater or DIY audio projects. The board streams audio wirelessly from Bluetooth sources and provides a compact, integrated solution for multiroom or multispeaker setups. Key benefits Wireless convenience: Bluetooth 5.0 input enables easy streaming from smartphones, tablets, and other Bluetoothenabled devices. Flexible 4channel power: Two channels deliver up to 50W each, and two channels deliver up to 100W each, allowing a mix of medium and power speaker pairs on a single board. Dualsubwoofer support: Designed to accommodate dualsubwoofer configurations for deeper, more even bass in home theater or dedicated audio setups. DIY friendly: Compact board designed for integration into custom enclosures, stereo systems, or powered speaker builds without needing multiple separate amplifiers. Consistent performance: Digital power amplification provides efficient and reliable amplification for multiple speakers with clear and dynamic sound. What to expect in terms of function and performance Four amplified outputs: A fourchannel audio path suitable for driving a complete small to midsize speaker array. Bluetooth streaming: Pair your mobile device or computer to receive audio wirelessly with minimal setup. Power configuration: The board provides 50Wx2 + 100Wx2, enabling different speaker pairings and subwoofer configurations depending on your enclosure and supply. Subwoofer integration: Built to support dual subwoofers, enhancing bass response for a fuller home theater experience. Compatibility and integration Bluetooth compatibility: Works with Bluetoothenabled devices such as smartphones, tablets, and laptops for wireless audio playback. System integration: Suitable for home theater projects, DIY powered speaker systems, or multispeaker configurations where four channels are desirable or required. Size and form factor Designed as a compact amplifier board suitable for enclosurefitting DIY projects and small to medium audio installations. Materials and build Built around the TPA3116 audio amplifier architecture as a digital power amplifier board. (Specific material details are not provided.) Performance considerations Power availability: Output levels depend on the power supply and the impedance of connected speakers. The specified ratings are 50Wx2 and 100Wx2 as indicated, with the appropriate configuration and supply required to achieve those numbers. 23 use scenarios Home theater upgrade: Use the XHA310 to drive a 4speaker setup (two mains at higher power and two smaller channels for surround or rear speakers), with two subwoofers to enhance bass for a more immersive moviewatching experience. DIY powered speaker system: Build two pairs of speakers with Bluetooth audio input, using two power channels for front speakers and two channels for subs or rear speakers, all on a single compact board. Small venue or classroom audio: Deploy a Bluetoothenabled amplifier to stream from a wireless source and deliver clear, distributed sound across four speakers for presentations or performances. Notes Power outputs are specified as 50Wx2 + 100Wx2 and depend on supply voltage and speaker impedance. The board is designed to work with Bluetoothenabled audio sources and is intended for DIY projects, home theater, and multispeaker configurations.
