LEADSIGN 150W 37" Bluetooth 5.0 TV Soundbar — 2.1 Channel, 4 Built‑in Subwoofers, HDMI ARC/Optical/USB/AUX + Remote

Important setup note: Many smart TV apps (for example Netflix) output audio in Dolby or DTS by default. This soundbar does not support Dolby or DTS, so you must switch the app or TV audio output to "Stereo" (or disable Dolby/DTS) or the bar will be silent. On some TVs you may need to set output to PCM and enable HDMI‑CEC; also choose the correct audio output option such as "Optical", "Receiver" or "External Speaker". Connection & control: Use the included remote or the front volume knob to operate the soundbar. Inputs supported: Bluetooth 5.0, USB, AUX, Optical (SPDIF) and HDMI (ARC). When playing files from a USB drive, press the on‑screen/remote “Playback” symbol to start audio or video playback. Sound tuning & modes: The unit offers 7 listening modes — including 4 preset EQs for Music (EQ1), Movie (EQ2), News (EQ3) and Musical Instruments (symphony, piano) plus a 3D surround mode. There are also 4 manual modes that allow you to adjust Bass+/- and Treble+/- to taste. Design & audio configuration: This 37‑inch home theater soundbar is a 2.1 channel system with 2 full‑range speakers, 2 tube speakers and 4 built‑in subwoofers (total 6 speakers) delivering deep bass and adjustable treble. Rated power is 150W and it streams wirelessly via Bluetooth 5.0. EQ quick tip: The DigitalBasics S2 TV Sound Bar features four equalizer presets—press the EQ button on the remote to switch between Music (EQ1), Movie (EQ2), News (EQ3) and Musical Instruments. TV box audio settings (recommended): 1) Roku — Home -> Settings -> Audio: set HDMI to PCM‑Stereo when using HDMI ARC, or set HDMI and SPDIF to PCM‑Stereo when using Optical; select Stereo for Audio -> Audio Mode. 2) Fire Stick — Settings -> Sound and Display -> Audio: choose "Stereo". 3) Apple TV — Settings -> Audio & Video -> Audio Out: select "Stereo". 4) Other TV boxes — locate the Audio settings and pick the "Stereo" option.
