Fosi Audio BT30D: 2.1-channel Class D amplifier

Fosi Audio BT30D is a 2.1-channel Class D amplifier capable of delivering 2x50W + 100W of power into a 4 ohm load thanks to two TI TPA3116D2 amplifier chips. It also features Bluetooth 5.0 for stable and high-quality wireless reception. There are at least 5 potentiometers on the front panel.

The first three are for adjusting the volume, as well as equalizing the bass and treble, while the other two are for cutting the subwoofer frequency and adjusting the subwoofer volume. The rear panel houses an RCA input, a speaker output, and two subwoofer outputs: one for a passive subwoofer and one for an active subwoofer. This small BT30D amplifier is ideal for creating a 2.1-channel home theater system and enjoying immersive bass.

Inside the Fosi Audio BT30D amplifier are two TI TPA3116D2 amplifier chips, delivering 2x 50W + 100W into 4 ohms. This is quite a sufficient power reserve to provide a 2.1-channel system.

In addition to the RCA input, the BT30D is equipped with a Bluetooth 5.0 receiving chip, allowing you to use your phone or tablet for remote audio streaming.
