greater flexibility in the placement of their HW-E550 Surround Sound Bar with 3D Depth Sound - they can either place the sound bar horizontally below their TV or split the sound bar into two vertical speakers. By attaching each speaker to an included base, the soundbar can also morph into a traditional looking 2.1-channel system with half-tall speakers. Those looking for a rich audio experience will be pleased with the outstanding sound quality and performance of the HW-E550. In addition, the HW-E550 offers Smart Volume, an active audio monitoring system that prevents spikes in volume when TV channels or radio stations are changed. This not only protects the listeners' ears but also the soundbar's speakers, helping to extend usage of the device. The HW-E550 comes with six different settings - Movie, Game, Drama, Music, News and Sports - to deliver optimal sound quality according to the content of the video. Samsung's 3D Depth sound technology also synchronises the audio to 3D images for some sense of depth and immersion so you will enjoy realistic, cinematic surround sound effects without the need for additional satellite speakers. The HW-E550 is equipped with two HDMI inputs and one HDMI output so you can easily connect to Blu-ray players, set-top boxes and gaming consoles. Support for HDMI Audio Return Channel (ARC) puts audio data into the video connection and eliminates the need for separate audio cables. The HW-E550 is Bluetooth-enabled providing wireless playback of audio files from other Bluetooth devices. A USB port provides another connectivity option. The sound bar is incredibly thin and sleek. Its main speaker weighs less than 2kg and is easily wall-mountable, making it an ideal choice for fans of minimalist design or those who want to free up more space in their home entertainment room. With Samsung's proprietary dual band 5.2/5.8GHz wireless technology, wires are not required to link the speaker bar and the subwoofer. The subwoofer, which has a frequency response of 40Hz to 200Hz, can be placed anywhere in the room without any compromise.
