Fosi Audio HT4S Bluetooth Amplifier 5 Channels Class D 2xTPA3116 5x30W 4Ω
The HT4S from Fosi Audio is a compact integrated power amplifier with 5 channels capable of delivering 30W each thanks to two TPA3116 amplifier chips.
For even greater flexibility, the HT4S can alternate between 5.0 and 4.1, allowing you to use it in a 5-speaker full-range configuration or reserve one of the channels for a passive subwoofer. Furthermore, the HT4S has a pre-out so you can connect an active subwoofer and enjoy a 5.1 surround configuration.
Finally, for even more versatility, the HT4S offers a Bluetooth input in addition to the Toslink optical input and the 3.5mm jack auxiliary input. As an aesthetic touch, the light strip on the front of the device changes colour according to the input used: blue for Bluetooth, orange for the auxiliary input and red for the optical input.
