Bluetooth 5.0 stereo amplifier

Small, simple and ready for clean two-channel power.

The Fosi Audio BT10A is a compact 2.0 Class-D amplifier for passive speakers, desktop audio and lighter two-channel sim racing setups. It gives you Bluetooth 5.0 streaming, a 3.5 mm AUX input, physical bass and treble controls, speaker binding posts and an included 19V / 4.74A power supply in a small metal chassis.

Where it makes sense

A neat amp for compact speakers or lighter tactile feedback.

The BT10A is best when the setup needs to stay simple: a small pair of passive speakers, a compact desktop system, or a modest two-channel tactile setup where you want physical volume control and quick level tuning. It is not the amp we would choose for very large 100W-300W tactile transducers, but for sensible 50W-class use it gives a tidy, affordable starting point.

01Compact speaker amp

Drive a pair of passive bookshelf or desktop speakers without a full-size receiver.

02Light tactile setups

Useful for modest left/right shaker builds when the effect level is tuned sensibly.

03Physical control

Volume, bass and treble are on the front panel, so quick adjustments do not require software changes.

04Simple wiring

Bluetooth or AUX in, speaker outputs out. No extra processing layer to fight.

Bluetooth or AUX

Stream wirelessly or plug in a dedicated source.

Bluetooth 5.0 makes the BT10A easy to use with a phone, tablet or laptop, while the 3.5 mm AUX input is better when the signal should stay wired. For sim racing tactile use, AUX is usually the cleaner choice because the PC or audio interface can feed the amplifier directly.

Bluetooth 5.0 Up to 12 m range 3.5 mm AUX Speaker output

Front panel control

Volume, bass and treble exactly where you need them.

The front panel keeps the important controls under your fingers. Use the volume knob for overall output, then trim bass and treble to match the speakers, room or tactile effect. For a rig, this is handy when you want to reduce shaker intensity during a long session without opening software.

Speaker terminals and 12-24V DC input

Clean rear panel for a small permanent setup.

The rear panel gives you a 3.5 mm AUX input, Bluetooth antenna connector, passive speaker outputs and DC power input. The amplifier supports 2-8 Ohm loads, so the wiring still matters: keep the final impedance safe and use proper speaker cable for the distance.

Bluetooth 5.0

Quick wireless playback for phones, tablets and laptops.

3.5 mm AUX input

Use a wired source when latency and signal consistency matter more.

19V / 4.74A PSU

The included external power supply is ready to run the amplifier out of the box.

2-8 Ohm load range

Suitable for compatible passive speakers or small tactile transducers.

TI TPA3116D2 Class-D platform

Efficient power without a bulky receiver.

The Texas Instruments TPA3116D2 chip is a proven compact Class-D platform. It keeps the BT10A small and efficient while giving enough output for near-field speakers, desk audio and lighter cockpit feedback.

What’s in the box

Everything needed to power the amplifier.

The package includes the BT10A amplifier, Bluetooth antenna, 19V / 4.74A power adapter, AC cord and user manual. Speakers, bass shakers, speaker wire and AUX cable are selected separately based on your setup.

Setup workflow

Connect, power up and tune gently.

The BT10A is straightforward, but a clean setup still matters. Keep speaker polarity consistent, start with low volume and increase the level gradually.

1Choose the input

Use Bluetooth for convenience or AUX for a wired PC/audio interface signal.

2Wire the outputs

Connect compatible passive speakers or tactile units and keep the load within 2-8 Ohm.

3Power the amp

Use the included 19V / 4.74A power supply and leave enough airflow around the chassis.

4Tune by feel

Raise volume in small steps, then adjust bass and treble to match your speakers or rig.
