LG GX

Features

GX (Gallery Series) Sounbar & Sub: The LG GX Soundbar & Sub system has been designed to match perfectly with LG's Gallery Series OLED TVs (55", 65" and 77" models); however, it can be used with other LG TVs and other brands of TVs. The system includes an active soundbar speaker and a wireless powered sub with a total system power of 420 watts.

• Active Soundbar Speaker: The active soundbar speaker incorporates dedicated front left, center, and front right channels powered by a built-in 220W amplifier (80W x 2ch to the front left & right channels and 40W x 1ch to the center channel).The soundbar can be positioned on a flat tabletop surface using the included feet. It can also be wall mounted using the included wall-mount brackets (mounting screws not supplied). The soundbar should be centered above or below your flat-panel television.
• Wireless Powered Subwoofer: The wireless powered subwoofer houses a front-firing 6" woofer powered by a built-in 220W (RMS) amplifier inside a bass reflex cabinet with a rear-firing port. Because its wireless, you can place the subwoofer almost anywhere in your room (up to 33' from the soundbar). But it is better to place the subwoofer near the main unit. Turn it slightly toward the center of the room to reduce the wall reflections.

Note: The active soundbar speaker and wireless powered sub will both need to be plugged into an AC wall outlet or surge protector (sold separately - see Accessories Tab). The active soundbar speaker comes with an external AC power adapter with an attached 58" DC cable and a detachable 3' AC power cord. The wireless powered subwoofer comes with a detachable 5' AC power cord.

Wireless Surround Ready: The GX soundbar system has been designed to integrate with LG's SPK8-S optional wireless surround speakers (sold separately), adding dedicated rear channels with wireless convenience for 5.1ch surround sound. The SPK8-S includes an amplifier/receiver unit and pair of speakers that link wirelessly to the LG soundbar.

Note: The LG Wireless Surround Sound Kit (SPK8-S) will require and AC power outlet connection and speaker wire connection. The kit's wireless receiver/amplifier receives its audio signal wirelessly from a compatible LG soundbar speaker. The rear surround speakers connect to the wireless receiver/amplifier using speaker wire. The wireless receiver/amplifier also requires connection to an AC power outlet.

AI Sound Pro: The GX incorporates LG's AI Room Calibration and AI Sound Pro to ensure the soundbar and subwoofer system sounds great in your room and with your source content. AI Sound Pro automatically and intelligently analyzes source content in real-time to enhance sound quality. It automatically adjust sound levels (including Bass & Treble) based on the content you are watching and listening. From powerful action to dramatic dialog, you'll hear your entertainment with crystal-clear, detailed audio.

Meridian Hi-Res Audio: LG partnered with Meridian Technology, pioneers of High-Resolution Audio, to combine advanced signal processing and refined hardware design, creating a soundfield with greater height, width and depth. This leading audio processing technology also provides sound quality that surpasses CDs, and allows you to enjoy stunning 24-bit/192kHz audio resolution (for HDMI & Optical), as well as 24-bit/192kHz upsampling for other audio sources (such as Network and Bluetooth).

Digital Surround Sound Formats: The LG GX soundbar and sub system supports the following multichannel digital audio formats through its HDMI & optical digital inputs.

Immersive Surround: The LG GX supports Dolby Atmos & DTS:X. However, the soundbar only features front left, center, and front right channels; with no height or surround channels - so Dolby Atmos and DTS:X, as well as other Dolby Digital and DTS content will be down-mixed to 3.1 channel surround.

• Dolby Atmos: With Dolby Atmos sound comes alive from all directions, including overhead, to fill your home theater with astonishing clarity, power, detail, and depth. Rather than being constrained to channels, sounds exist as individual entities that are precisely placed and moved in three-dimensional space. A new sensation of height immerses you in the action, creating a full audio atmosphere and realistically depicting objects moving overhead. Dolby Atmos renders everything from dialogue to quiet scenes to whirlwind action with astonishing clarity, richness, detail, and depth. It all comes together in sound that excites your senses and inspires your emotions to deliver the full impact of entertainment.
• DTS:X: DTS:X is the next generation object-based, multi-dimensional audio technology from DTS. Unbound from channels, DTS:X conveys the fluid movement of sound to create an incredibly rich, realistic and immersive soundscape - in front of, behind, beside and above the audience - more accurately than ever before. DTS:X offers the ability to automatically adapt the audio to the speaker layout that best fits your space.

Notes:

• The soundbar's HDMI input and output support Dolby Atmos and DTS:X. Your source device must also support Dolby Atmos and DTS:X.
• The soundbar's optical (toslink) digital input only supports Dolby Digital (5.1ch), DTS (5.1ch), and 2ch PCM.

• Standard: Standard mode provides optimum sound for most applications.
• Movie: Movie mode lets you enjoy a more immersive and cinematic surround sound.
• Music: Muse mode lets you enjoy better sound from music sources.
• Bass Blast+: Bass Blast+ reinforces the bass for a more powerful sound.

Connections

HDM 2.0 Input/eARC Output: The LG GX soundbar speaker system is equipped with one HDMI 2.0 input and HDMI 2.0 eARC output that support up to 4K/HDR video, 4:4:4 color sub sampling, and HDCP 2.3. The HDMI jacks also support Dolby Digital/DTS multichannel audio formats (including Dolby Atmos & DTS:X). The eARC (Enhanced Audio Return Channel) function of the soundbar's HDMI output enables an HDMI eARC capable TV to send its audio stream to the HDMI output of the soundbar system.

• 4K Pass-Through: 4K pass-through allows the GX to receive ultra high-definition resolution video and pass the video signal to a 4K compatible TV or display monitor. The system supports 4K@60/50Hz (4:2:0), 4K@24/25/30Hz (4:4:4). 1080p, 1080i, 720p, and 480p video signals.
• HDCP 2.3: The soundbar's HDMI input and output also support HDCP 2.3, which fully complies with the latest copyright protection standard for 4K video transmission. HDCP 2.3 is supported by the soundbar system's HDMI input and output. HDCP 2.3 is short for "High bandwidth Digital Content Protection" and is used for 4K video copyright protection for compatibility with Ultra HD Blu-ray players and 4K Satellite/Cable providers.
  
• 4:4:4 Color Sub sampling: The system's HDMI jacks support 4:4 color sub sampling for more vibrant and lifelike images, as well as 4:2:0 color sub sampling. With 4:4:4, luminance (brightness) and Chroma (color) are sampled at the same rate, resulting in an RGB color palette as big as the video sampling rate for a video image with more total colors, plus greater color accuracy and detail.
  

Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K performance.

HDR (High Dynamic Range): HDR (High Dynamic Range) reproduces a greater dynamic range of luminosity or brightness levels, bringing greater contrast & wider color spectrum to the screen. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors. The LG GX supports the following HDR formats - HDR10 and Dolby Vision.

• HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It supports 10-bit color and 1,000 nits. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
• Dolby Vision: Dolby Vision Content has dynamic metadata that is produced during content creation, capturing the dynamic properties of each scene. This dynamic metadata is used to optimize the picture brightness curve on a frame-by-frame basis. Dolby Vision is the preferred HDR format by major Hollywood Studios

Note: Use a premium high-speed 18Gbps HDMI cable for the best HDR performance.

eARC (Enhanced Audio Retain Channel): Along with standard ARC (Audio Return Channel), the LG SN8YT supports eARC (Enhanced Audio Return Channel). ARC and eARC allows audio to be sent from your compatible TV to the soundbar system through the same HDMI cable already being used to send audio and video to your television. This eliminates the need for extra cables connected to your television.

• eARC will support uncompressed audio formats like Dolby Atmos (Dolby TrueHD), DTS:X, Dolby TrueHD, DTS-HD, DTS HD Master Audio, and 2/5.1/7.1ch PCM.
• ARC is limited to Dolby Atmos (Dolby Digital Plus), Dolby Digital, Dolby Digital Plus, DTS, DTS ES, and 2/5.1/7.1ch PCM.

Notes:
