The LS-T10 comes preprogrammed with IR codes for nine major TV brands. This means you can use your TV remote to control the unit right out of the box. It switches on automatically with your television & responds to TV remote volume commands. Other functions are handled via the supplied remote, but for everyday use, the LS-T10 is set-&-forget, seamlessly replacing flat-screen sound with immersive TV audio. It's easy to listen to music & other audio programs, too. Just pair your cellphone, smartphone, tablet, or PC to the LS-T10 & start streaming wirelessly via the onboard Bluetooth technology. From your smartphone's music apps (such as Spotify, Sound Cloud, & other internet radio services) to locally stored libraries, Bluetooth technology lets you enjoy content quickly & easily. The LS-T10 is powered by Aura Sphere DSP (Digital Signal Processing) technology. It works by optimizing driver output to create a 3D surround effect from stereo sources. Unlike other DSP technologies, Aura Sphere expands the sweet spot (the area in front of the TV where audio sounds best) to create a 3D soundfield that places the listener in the centre of the action, wherever they're sitting.
