FOSI AUDIO BT30D Class D 2.1 Amplifier Bluetooth 5.0 2xTPA3116D2 2x50W + 100W 4 ohm
The Fosi Audio BT30D is a 2.1-channel Class D amplifier capable of developing 2x50W + 100W power under 4 ohm thanks to two TI TPA3116D2 amplifier chips.

The first three are for volume control as well as bass and treble equalization, while 2 others offer subwoofer frequency cutoff and subwoofer volume control. The rear panel features an RCA input, a speaker terminal output and two subwoofer outputs: one for passive subwoofer and one for active subwoofer. This small BT30D amplifier is ideal for setting up a 2.1-channel home theater system and enjoying immersive bass.
