2.1 channel Dolby Atmos sound bar

The Yamaha SR-B40ABL is a 2.1 channel sound bar system with a wireless subwoofer. It delivers Dolby Atmos immersive audio for TV shows, movies, games and music. The system includes the sound bar, subwoofer, power cords, an HDMI cable and a remote control.

200 W system with wireless subwoofer

This system suits viewers who want spatial sound and richer bass without running cables across the room. The wireless subwoofer handles low frequencies down to 33 Hz while the bar covers 210 Hz to 22 kHz. Buyers who need more than 2.1 channels or additional HDMI inputs should look elsewhere.

HDMI eARC and optical connectivity

A single HDMI eARC connection carries audio from a compatible TV and allows volume control via the TV remote. An optical TOSLINK input provides an alternative digital link for displays without eARC. The bar also offers a USB-A port for service use.

Questions about this item

How do I connect the SR-B40ABL to my TV using HDMI eARC, and what step is often missed?

Connect the supplied HDMI cable from the TV's eARC port to the sound bar's HDMI out, then enable HDMI Control (CEC) on the TV so the bar powers on and switches inputs automatically.

What part of the SR-B40ABL system will likely need replacement first, and why?

The wireless subwoofer's built-in amplifier runs at 2 Ohms and 100 W; its electrolytic capacitors will age faster than the sound bar's 4 Ohm, 50 W per channel modules.

At what volume level does the SR-B40ABL's protection circuit engage during a long movie session?

Sustained output near the 200 W total rating (50 W × 2 front channels plus 100 W subwoofer) triggers thermal protection, causing the system to mute briefly until the heatsinks cool.
