S-299 4.1 Channel Digital Power Amplifier Bluetooth5.0 — Portable Dual-Use Car & Home, 4*40W, Remote, USB/SD, AUX/RCA, Subwoofer Output, High Sound

Compact yet powerful, the S-299 is a 4.1-channel digital power amplifier designed for both home and vehicle use. Its unique output architecture lets you split the 4.1 channels into two independent 2.0 channel groups, with separate volume control for each group, plus a dedicated low-frequency output for connecting an active subwoofer — easy to configure as 2.0, 2.1, 4.0 or 4.1 systems. Rated output is 40W × 4 and it supports speakers with 4-8 ohm impedance, making it capable of driving most car, boat and home speakers while keeping distortion low and reproduction accurate. For source flexibility the unit accepts Bluetooth5.0, stereo RCA and 3.5mm AUX inputs (compatible with ip-ad, cellphone, MP3 player, CD player, dataplay, computer, decoder, etc.), and also plays from USB(U-disk), SD Card and M-MC Card for lossless music on the go. Controls include a volume knob plus treble and bass adjustment for fine tuning, an LED display that shows operating status in real time, and a convenient remote control for easy operation. Operating on DC 12V-14V, the S-299 is suited to desktop setups as well as cars, boats, RVs and golf carts where a compact, low-distortion amplifier is required.
