TINYSINE TSA3120B PARTY MODE Stereo DSP Amplifier Module DSP Bluetooth 5.1 2x30W

The TinySine TSA3120B PARTY MODE is a compact stereo audio amplifier / Bluetooth receiver module designed for DIY projects, custom speakers, multiroom installations, and portable audio systems. It combines efficient digital amplification, Bluetooth connectivity, and an integrated DSP processor, all in a small and easy-to-integrate format. Its key feature is its Party mode, capable of wirelessly linking multiple boards to broadcast music simultaneously across several speakers.

TinySine TSA3120B PARTY MODE: efficient stereo amplification

The TSA3120B delivers up to 2 x 30 watts in stereo thanks to its TAS5756M chip, allowing it to efficiently drive 4Ω or 8Ω passive speakers. Thanks to its Class D architecture, it offers excellent energy efficiency above 90%, reducing heat and power consumption.

This technology makes it an ideal solution for portable speakers, battery-powered systems, or installations where space is limited.

TinySine TSA3120B PARTY MODE: built-in Bluetooth for instant wireless streaming

The board features Bluetooth 5.x connectivity, allowing music to be streamed directly from a smartphone, tablet, or computer without any additional external module. Pairing is quick and easy: simply power the board, search for the device “TSA3120B”, and connect.

It also supports advanced technologies such as Qualcomm TrueWireless and aptX, improving connection stability and audio quality on compatible devices.

TinySine TSA3120B PARTY MODE: multiple synchronized modules

The Party Mode version sets this model apart from standard Bluetooth amplifiers. It allows multiple TSA3120B boards to be wirelessly connected so they all play the same music in perfect sync.

In practice, one board acts as the transmitter (master) and the others as receivers (slave). This setup is particularly useful for:

• parties and events
• multiroom installations
• large indoor or outdoor spaces
• scalable audio systems

TinySine TSA3120B PARTY MODE: integrated DSP

The TSA3120B features an ADAU1701 DSP processor, a major advantage for audio enthusiasts seeking precise adjustments. Using SigmaStudio software, it becomes possible to deeply customize the sound rendering according to project needs and the characteristics of the speakers used.

Users can adjust bass, midrange, treble, overall gain, configure active filters, set up crossovers, apply delays, or fine-tune advanced equalization. Each adjustment helps achieve a more balanced, dynamic sound perfectly suited to the installation.

This flexibility enables fully customized audio projects with a much higher level of optimization than a standard amplified module.

TinySine TSA3120B PARTY MODE: connectivity and easy integration

The module operates with a 12V to 24V DC power supply, making it compatible with many power adapters or batteries. Its compact size of 105 x 75 x 20 mm makes it easy to integrate into a DIY speaker, audio furniture, or a custom enclosure.

Additional ports also allow connection of:

• external potentiometers
• volume controller
• USBi DSP programmer
• custom control buttons

It is suitable for both hobbyists and experienced makers.
