FOSI AUDIO HT4S Amplifier Bluetooth 5 Channels

The HT4S from Fosi Audio is a compact integrated amplifier with 5 channels capable of delivering 30W each thanks to several 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.

Fosi Audio HT4S: multiple uses

The Fosi Audio HT4S is ideal for home cinema and Hi-Fi set-ups, but can also be used with up to 5 bass shakers/exciters for an immersive gaming setup.

Fosi Audio HT4S: a comprehensive control interface

On the front panel of the Fosi Audio HT4S, you'll find a relatively comprehensive control interface for adjusting bass and treble tones, overall volume, and also the volume of a passive subwoofer.
