The premium home theatre system features 5.1 channel surround sound and has a power output of 600W. The sound bar delivers sound through 'Tall boy' and rear speakers. A dedicated external subwoofer is also there that works with a 3-channel soundbar to deliver theatre-like surround sound, the company said. Connectivity options include Bluetooth and NFC that would let users connect their devices for streaming music. The HT-RT40 also comes with 'Music Center' through which users can browse music via their smartphones. Other specifications include a USB port and a HDMI out, which can also be synced with Bravia TVs. The home theatre also features 'S-Master HX' digital amp for delivering high-frequency ranges and 'ClearAudio+' that automatically adjusts TV sound settings. It costs Rs 22,990 in India.
