    Asked by Ann.

    • Answer Hi there, Ann. Thank you for sharing your experience with us. We understand your situation regarding the compatibility between your LG Nanocell TV and the LG S70TR Home Theater Soundbar. Based on our review of the official LG product details, the LG S70TR is designed with features such as LG TV Sound Sync that enable seamless connectivity with LG TVs.

  • QuestionI have an LG OLED C5 series TV. I will be mounting the TV to the wall. Are there LG brackets that I can use to hang my S70TR soundbar from the C5 OLED TV? Could I use the brackets that come with the soundbar or do those only work for wall mounting?

    Asked by Andrew.

    • Answer The LG 5.1.1-Channel S70TR Home Theater Soundbar with Wireless Subwoofer and Rear Speakers, Dolby Atmos®, DTS:X, WOW Orchestra - Black, does not come with an exclusive LG OLED Synergy Bracket designed for LG OLED evo C Series TVs, that can be used as a TV stand or mounted with your LG OLED evo C Series TV on the wall. The bracket is designed to place the sound bar in the perfect position for the most optimal sound experience, and it attaches directly to the TV without additional damage to your wall. IT is only compatible with the 55”, 65”, and 77” OLED evo C2, C3, C4 & C5 models, and the bracket is only available and compatible with the SC9S LG Soundbar C for TV with Dolby Atmos® and Synergy Bracket 3.1.3 channel...^Ivan.

  • QuestionDoes this soundbar support 5.1 channels of PCM through the HDMI input? Looking to know if can play Switch or Switch 2 surround sound audio through the HDMI input.

    Asked by Jack.

    • Answer Hi, Jack. Thank you for your question! Yes, the LG Soundbar (S70TR) model does support 5.1 channels of PCM audio through the HDMI input. This means you can enjoy surround sound from devices like your Nintendo Switch or Switch 2 when connected via HDMI. To get the best audio experience, make sure your Switch is set to output audio in surround sound format (5.1 PCM) through the HDMI settings. You may also want to ensure that your TV or receiver is configured to pass through the 5.1 audio signal to the soundbar for full surround sound.

  • QuestionWhat height should rear speaker be placed at on rear wall & what angle should they be tilted at? Room is 17x12. Main seat is a 3 seat couch 8x3 in middle of rear wall. 65" lg tv with S70TR soundbar on front wall under tv. Sub is on right side of on floor.

    Asked by BigD.

    • Answer Hi, there. Thank you for reaching out to us regarding LG Soundbar (S70TR) model. For optimal sound performance in your room, you’ll want to position your rear speakers correctly to ensure balanced surround sound. Here's what we recommend: Ideally, the rear speakers should be placed at ear level when seated, which is around 36-40 inches from the floor. Since your main seating area is a couch in the middle of the rear wall, the speakers should be mounted or placed on stands at this height for the best sound distribution. For a more immersive surround sound experience, aim the speakers toward the seating area at a slight angle (about 45 degrees). Given your room dimensions (17x12), placing the rear speakers about 1-2 feet away from the side walls will also help avoid too much reflection, ensuring clearer sound. For the subwoofer, you're doing great with it on the floor to the side; just keep it away from corners, as this can cause a muddier bass. You can download it's owner's manual through this link: https://www.lg.com/us/support/product/lg-S70TR.AUSALLK and check for pages 2-6 for installation. Let us know if you need further assistance, and don’t hesitate to send us a private message on social media @LGUSSupport for any additional questions or troubleshooting. ^Juvy

  • QuestionWill this system work with a sony tv?

    Asked by Timmy.

    • Answer Hi, Timmy. Thank you for reaching out to us about the LG Soundbar (S70TR) model. Yes, this unit should work with a Sony TV as long as the TV has the necessary audio output options, such as HDMI ARC (Audio Return Channel) or optical audio output. Most modern Sony TVs support these connections, allowing you to easily connect the soundbar for optimal audio performance. If your TV has HDMI ARC, you can use an HDMI cable to connect the soundbar to the TV, and it will handle both audio and video signals. Alternatively, you can use the optical cable if that’s more convenient. For more information regarding the product, you may visit https://www.lg.com/us/sound-bars/lg-s70tr-sound-bar. If you need help with the setup or have more questions, please send us a private message on social media @LGUSSupport. We’re here to assist you. ^Juvy

  • QuestionWhere are the set up instructions? We bought these speakers to go with the LG OLED TV, and there is nothing in the box that says how to set it up with the TV, not even a QR code.

    Asked by Customer.

    • Answer The included instructions are basic and indicate where to plug into your LG TV. The problem is with the manual of your LG TV; there isn't one! There a specific HDMI port on the LG tv for your soundbar; it is labeled 'ARC' or 'eARC'. The not so fun part if looking for the soundbar settings/options on your TV; it will be trial and error for a while.

  • QuestionWill this sound bar work with any TV with a HDMI connection?

    Asked by Malachismom.

    • Answer Hello there, Malachismom. Thank you for sharing your inquiry with us. We understand that you're asking about the compatibility of your S70TR soundbar with any TV that has an HDMI connection. Yes, your LG S70TR soundbar is designed to work with any TV that has an HDMI connection, especially those with an HDMI ARC (Audio Return Channel) or eARC (enhanced Audio Return Channel) port. This allows the audio from your TV to be sent back to the soundbar through the same HDMI cable. While it offers advanced features and optimization when paired with compatible LG TVs (like WOW Orchestra), it will still deliver excellent sound quality with other TV brands via HDMI. https://www.bestbuy.com/site/lg-5-1-1-channel-s70tr-home-theater-soundbar-with-wireless-subwoofer-and-rear-speakers-dolby-atmos-wow-orchestra-black/6578017.p?skuId=6578017 Please send us a private message on Social Media @LGUSSupport and our team will be more than happy to explore possible solutions.

  • QuestionWhat is the codec and the bit rate the rear speakers and the sound bar use to stream the two rear channels? Is the bit rate higher in, say, S80TR using WiFi?

    Asked by kot.

    • Answer Hi there, Kot. We understand your inquiry about the wireless codec and bit rate for your LG S70TR’s rear speakers and sound bar streaming two rear channels. Your S70TR uses LG’s proprietary 2.4 GHz wireless digital link to transmit uncompressed PCM audio to the rear modules and subwoofer. While LG doesn’t publish an exact “bit rate” figure, this link supports full‑bandwidth, high‑resolution audio (up to 24‑bit/48 kHz), which equates to roughly 2–3 Mbps of data per channel. Regarding the S80TR, it leverages your home Wi‑Fi network (2.4 GHz/5 GHz) for rear‑speaker transmission. Although the underlying audio codec remains PCM for maximum compatibility and latency control, the available Wi‑Fi bandwidth can allow slightly higher throughput—helpful in challenging RF environments—but LG does not specify a higher formal “bit rate” in its materials. Both models are optimized for reliable, low‑latency delivery rather than adjustable bit‑rate streaming. A quick troubleshooting step: if you ever notice audio drop‑outs or sync issues, please ensure your sound bar’s firmware is up to date. From your remote, go to Home > Settings > General > About This Sound Bar > Software Update to check. Also confirm the rear modules are within 20 ft of the bar and avoid obstructions like large metal objects. https://www.bestbuy.com/site/lg-5-1-1-channel-s70tr-home-theater-soundbar-with-wireless-subwoofer-and-rear-speakers-dolby-atmos-wow-orchestra-black/6578017.p?skuId=6578017 If you’d like more details or run into any issues, please send us a private message on Social Media @LGUSSupport and our team will be more than happy to explore possible solutions.

  • QuestionI have an older model 4 ch LG soundbar, and the Bluetooth range is terrible. The subwoofer has to be right next to the soundbar to stay connected. Do these newer models still have connection issues?

    Asked by Colin.

    • Answer Hello there, Colin. Thank you for sharing your experience with us. We understand your situation with limited wireless range on older LG soundbars. The new S70TR 5.1.1‑channel Home Theater Soundbar features a Wireless Active Subwoofer designed for up to 30 feet of range under ideal conditions, so you should see an improvement over older 4‑channel models. As a first troubleshooting step, please ensure both the soundbar and subwoofer are placed at least 1–2 feet away from other wireless devices (like routers or cordless phones) and avoid large metal or concrete obstructions between them. Then, open the LG Sound Bar & AV Remote App on your iOS or Android device and perform a Firmware Over‑the‑Air (FOTA) update to make sure you’re running the latest system software. This can help optimize connection stability. https://www.lg.com/us/soundbars/lg-s70tr-home-theater-soundbar#pdp_specs If you continue to experience any issues, please send us a private message on social media @LGUSSupport and our team will be more than happy to explore possible solutions.
