It can also play audio from wirelessly connected Bluetooth devices.

Connections

HDMI (in/out) HDMI The number of these input and output connections. They are useful for connecting audio/video devices with HDMI (High-Definition Multimedia Interface) connections such as TVs, Blu-ray players, DVD players, and set-top boxes. An HDMI cable is used to carry audio and video signals on the same cable from one device to another. An HDMI cable connection is in the form of an HDMI port. While HDMI connections support a range of standard-, high-, and ultra high-definition video formats including 3D, Ultra HD, and HDR, not all systems support all formats (see these headings in the Features section for details). Depending on the product they also support ARC (Audio Return Channel - two-way digital audio travel between a soundbar or soundbase and a TV on the same cable) as well as transfer of PCM and standard and advanced Dolby Digital and DTS digital audio (see the Features section for more details); they do not support analog audio.
1/1
Optical digital audio (in/out) Optical digital audio The number of these input and output connections. These are useful for connecting audio devices with optical connections such as a TV, set-top box, Blu-ray player, etc. An optical digital audio interconnect, also called a Toslink cable or an optical cable, is a fiber optic cable used to carry digital audio signals as pulses of light from one device to another. An optical cable connection can be in the form of the small, squarish Toslink jack, or a smaller mini optical jack which looks a lot like a standard 1/8-inch mini-jack. Optical digital audio connections support PCM and up to 5.1 multi-channel Dolby Digital and DTS digital audio, but not the more advanced digital audio formats or analog audio.
1/0
Coaxial digital audio (in/out) Coaxial digital audio The number of these input and output connections. These are useful for connecting audio devices with coaxial connections such as a TV, set-top box, Blu-ray player, etc. A coaxial digital audio interconnect, also called a SPDIF cable or coaxial cable, is used to carry digital audio signals from one device to another. A coaxial cable connection is a single RCA jack. Coaxial digital audio connections support PCM and up to 5.1 multi-channel Dolby Digital and DTS digital audio, but not the more advanced digital audio formats or analog audio.
0/0
Stereo analog audio (in/out) Stereo analog audio The number of these input and output connections. These are useful for connecting two-channel analog audio devices such as a TV, set-top box, portable music player, etc. An audio interconnect, also called an audio cable, is used to carry analog audio signals from one device to another. A stereo (2-channel) analog connection can be in the form of a pair RCA jacks, or a mini-jack. Analog cable connections don't support digital audio.

Features

No. of channels No. of channels The number of audio channels the system has, whether the channels provide surround sound, and if applicable, whether optional accessories can be used to expand the system to more channels and/or to provide surround sound. The format is "X.Y" for non-surround and surround sound systems, and "X.Y.Z" for non-surround or surround systems with height channels. With non-surround systems "X" is the number of non-surround channels that are integrated into the soundbar or soundbase enclosure (2 means front left and right, 3 means front left, right, and center; there could be higher numbers - meaning more channels - but it still amounts to non-surround sound). With surround systems "X" is total number of channels that are integrated into the soundbar or soundbase enclosure (typically front left and right, or front left and right, and center) plus the number of surround channels handled by separate surround speakers (typically left rear and right rear, but there could also be left side and right side, or more). For all systems "Y" indicates the number of subwoofers (typically 0 or 1, but on occasion 2). For all systems with height channels "Z" is typically 2 (front left and right height channels) or 4 (front left and right and rear left and right height channels).
4.1 non-surround expandable to 4.1 Surround
No. of speakers supplied No. of speakers supplied The number of speakers that come with the system is shown in the format "X.Y" where "X" is the number of speakers other than subwoofers and "Y" is the number of subwoofers. The number of speakers can also be shown in the format "X" if no subwoofers are supplied. Most soundbar systems come with 1.1 speakers - the soundbar (that's the 1) and a subwoofer (that's the .1). Surround sound systems generally come with at least two rear surround speakers, so for a surround sound system with a soundbar and two surround speakers and no subwoofer the number of speakers in the system would be shown as 3.0 or 3; if a subwoofer is provided the number of speakers would be shown as 3.1. Soundbases typically don't come with a subwoofer, but may come with surround speakers.
