Sonos Arc - Top 10 Questions and Answers
BIKMAN TECHWelcome to the BIKMAN TECH blog! If you're considering upgrading your home theater audio, you've likely come across the Sonos Arc. This premium smart soundbar is a popular choice for movie lovers and music enthusiasts alike. But with so much technology packed into one sleek package, you probably have some questions. That's where we come in. This article answers the top 10 questions about the Sonos Arc, helping you understand its features and decide if it's the right fit for your home entertainment setup. Let's dive in!
1. What is the Sonos Arc and who is it for?
The Sonos Arc is a premium smart soundbar designed to deliver an immersive, cinematic sound experience for your TV, movies, music, and gaming. It features 11 high-performance drivers, including two upward-firing drivers, to create a multi-dimensional soundstage with Dolby Atmos. The Arc is ideal for anyone looking to significantly upgrade their TV's built-in speakers to a high-quality, room-filling audio system without the complexity of a traditional home theater setup. It's best suited for TVs that are 49 inches or larger due to its width of 114 cm (45 inches).
2. What is Dolby Atmos and how does it work on the Sonos Arc?
Dolby Atmos is a revolutionary surround sound technology that goes beyond traditional channel-based audio. Instead of just hearing sound from in front or behind you, Dolby Atmos creates a 3D soundscape by adding height channels. This means you can hear sounds as if they are happening above you, like a helicopter flying overhead or rain falling. The Sonos Arc achieves this effect with two dedicated upward-firing drivers that bounce sound off your ceiling to your listening position, creating a truly immersive and realistic audio experience. To get the full Dolby Atmos effect, you need a TV that supports it and content that is encoded in Dolby Atmos.
3. How do I set up the Sonos Arc?
Setting up the Sonos Arc is remarkably simple. Here’s a quick overview of the process:
- Unbox and place the Arc: Position the soundbar on a stable surface below your TV or use a compatible wall mount. Ensure there's at least 10.2 cm (4 inches) of clearance between the top of the Arc and the bottom of your TV so the upward-firing speakers are not blocked.
- Connect the cables: Plug the included power cord into an outlet and connect the HDMI cable from the Arc to your TV's HDMI eARC or ARC port.
- Use the Sonos app: Download the Sonos S2 app on your smartphone or tablet. The app will automatically detect the Arc and guide you through the rest of the setup process, which includes connecting it to your Wi-Fi network and adding your music streaming services.
4. What is Trueplay and do I need it?
Trueplay is a Sonos-exclusive software feature that customizes the sound of your speaker to the unique acoustics of your room. It uses the microphone on an iOS device (iPhone or iPad) to measure how sound reflects off walls, furniture, and other surfaces. It then fine-tunes the Arc's EQ to ensure the audio sounds as accurate and balanced as possible, no matter where you've placed it. While the Arc sounds great out of the box, using Trueplay is highly recommended to get the absolute best performance. The process takes only a few minutes and makes a noticeable difference.
5. Will the Sonos Arc work with my TV? What is HDMI eARC?
The Sonos Arc is designed to work with almost any modern TV. However, to get the best possible audio quality, including high-resolution Dolby Atmos, your TV needs an HDMI eARC (Enhanced Audio Return Channel) port. Here’s a breakdown:
- HDMI eARC: This is the ideal connection. It provides the necessary bandwidth for the highest quality, uncompressed audio formats like Dolby TrueHD (a lossless version of Dolby Atmos).
- HDMI ARC: Most modern TVs have this port. It can still pass a Dolby Atmos signal, but it's typically a compressed version (Dolby Digital Plus), which still sounds fantastic for most streaming content.
- Optical Audio: If your TV doesn't have an HDMI ARC port, you can use the included Sonos Optical Audio Adapter. This connection supports Dolby Digital 5.1 surround sound but does not support Dolby Atmos.
In short, the Arc will work with your TV, but an HDMI eARC port is required to unlock its full potential.
6. Can I add a subwoofer and surround speakers to the Sonos Arc?
Absolutely! One of the biggest advantages of the Sonos ecosystem is its modularity. While the Sonos Arc delivers impressive bass and a wide soundstage on its own, you can easily create a full wireless surround sound system by adding:
- A Subwoofer: You can pair the Arc with a Sonos Sub (Gen 3) for deep, powerful bass or a Sonos Sub Mini for a more compact setup. Adding a sub allows the Arc to focus on mid and high frequencies, resulting in even clearer dialogue and richer overall sound.
- Surround Speakers: For true surround sound, you can add a pair of rear speakers. Compatible options include the Sonos Era 100, Era 300 (which also have up-firing drivers for enhanced Dolby Atmos), Sonos One SL, or IKEA SYMFONISK speakers.
7. How does the Sonos Arc sound on its own?
On its own, the Sonos Arc produces a remarkably wide and detailed soundstage. Dialogue is exceptionally clear thanks to a dedicated center channel, a feature fine-tuned by Oscar-winning sound engineers. The sound is balanced, with crisp highs and a solid mid-range. While the bass is present and well-controlled for a soundbar, many users find that adding a Sonos Sub truly completes the cinematic experience by handling the lowest frequencies. For music listening, the Arc also performs very well, delivering a rich, room-filling sound that is impressive for a single speaker.
8. What audio formats does the Sonos Arc support?
The Sonos Arc supports a wide range of home theater audio formats to ensure you're getting the best sound from your content. Here is a table of the key formats:
Format | Details |
---|---|
Dolby Atmos | Both Dolby TrueHD (lossless) and Dolby Digital Plus versions are supported. |
Dolby TrueHD | Requires an HDMI eARC connection. |
Dolby Digital Plus | Requires an HDMI ARC or eARC connection. |
Dolby Digital | The standard for most broadcast TV and streaming services. |
DTS Digital Surround | A common surround sound format on Blu-rays and DVDs. |
Multichannel PCM | Uncompressed audio format, requires an HDMI eARC connection. |
Stereo PCM | Standard two-channel audio. |
9. How does the Sonos Arc compare to the Sonos Beam (Gen 2)?
The Sonos Beam (Gen 2) is another excellent soundbar from Sonos, but it's designed for smaller spaces and TVs. The main differences are:
- Size and Drivers: The Arc is much larger (114 cm vs 65 cm) and has 11 drivers, including dedicated upward-firing drivers. The Beam (Gen 2) has 5 drivers and uses psychoacoustic techniques to create a virtual Dolby Atmos effect.
- Soundstage: Due to its size and driver array, the Arc produces a much wider, more immersive soundstage that is better suited for larger rooms and a more cinematic experience.
- Ideal Use Case: The Beam (Gen 2) is a fantastic choice for small to medium-sized rooms and TVs under 55 inches. The Arc is the flagship option, ideal for larger rooms, bigger TVs, and those who want the best possible Dolby Atmos performance.
10. What are the ideal placement and room conditions for the Sonos Arc?
To get the best performance from your Sonos Arc, especially for Dolby Atmos, consider the following:
- Ceiling Height: A flat, reflective ceiling with a height between 2.4 to 4 meters (8 to 13 feet) is ideal for the upward-firing drivers to work effectively. Vaulted or angled ceilings can diminish the height effect.
- Placement: Place the Arc centered below your TV, either on a media stand or wall-mounted. Ensure the ends of the soundbar are at least a few centimeters (or inches) from any walls or obstructions to allow the side-firing drivers to create a wide soundstage.
- Clearance: As mentioned, keep at least 10.2 cm (4 inches) of space above the Arc so the upward-firing drivers have a clear path to the ceiling.
