PFFB 2.1-Channel Amplifier — ARC, Bluetooth 5.3, USB & Optical Multi-Input Subwoofer Amp

Compact multi-input amp designed for a 2.1-channel setup. The unit accepts ARC input for direct TV audio via ARC, simplifying source connection and delivering clearer, more immersive playback from television sources. In TONE mode you get dedicated control over BASS, MIDDLE and TREBLE to fine-tune mid-frequency response and improve vocal presence. Built to work with an external subwoofer, it integrates cleanly into a 2.1 system to provide stronger bass for movies and gaming. Connectivity covers ARC, Bluetooth 5.3, USB and optical fiber inputs so the amplifier will pair with a wide range of devices. A built-in DAC handles most input sources, enabling high-resolution decoding and faithful playback for a high-fidelity listening experience. Easy to install and set up for home theater or desktop audio use.
