The Best Settings for Vizio 2.1 Sound Bar
By Robert Jones · 2021-03-14
Had a Vizio 2.1 soundbar kicking about? They can be a bit tricky to get sounding right, but with a few simple tweaks to the settings, you can massively improve your TV and film experience. Robert Jones shares his real-world tips.
Right then, let's have a chinwag about getting the best out of your Vizio 2.1 soundbar. I know, Vizio isn't a massive name over here in the UK, but plenty of you lads and lasses have picked one up, especially on the cheaper end of things. And honestly, they can be a bit fiddly to get right straight out of the box, can't they? I've had a few Vizio bits and bobs through the workshop over the years, mostly the soundbars that come bundled with their TVs or those budget models you see around. They're not going to blow your socks off like a Meridian setup, but with a bit of tweaking, you can squeeze some decent sound out of 'em. Most people just plug 'em in and leave it, which is a crying shame, really. ### **Quick Verdict:** **For a budget 2.1 system, a Vizio soundbar can sound surprisingly good with the right settings, but don't expect miracles.**  *The Best Settings for Vizio 2.1 Sound Bar — tested in the SpeakersMag workshop.* ## First Things First: Getting Connected Properly Before we even talk about settings, you've got to make sure it's connected right. Honestly, this is where half the battle is won or lost. I've seen so many people moan about their soundbar sounding rubbish, only to find they're still using the old red and white RCA cables. Bless 'em. ### HDMI ARC/eARC: Your Best Bet If your TV has an HDMI port labelled "ARC" or "eARC", that's the one you want. It stands for Audio Return Channel, and it's brilliant because it sends the sound *from* the TV *to* the soundbar with just one cable. Plus, it usually lets your TV remote control the soundbar's volume, which is a real convenience. Now, make sure you're using a half-decent HDMI cable. You don't need to spend a fortune on some gold-plated nonsense, but avoid the cheapest pound-shop specials. A decent high-speed HDMI cable will do the trick. Plug one end into the TV's ARC port and the other into the soundbar's HDMI ARC port. Simple as that. Once connected, you'll probably need to go into your TV's audio settings and tell it to output sound via "HDMI ARC" or "External Speakers." Sometimes it's called "CEC" or "Anynet+" (Samsung) or "Bravia Sync" (Sony). Just enable it. This is usually where you select the digital audio format too, which we'll get to. ### Optical (TOSLINK): The Next Best Thing No HDMI ARC? Don't fret. The optical cable (often called TOSLINK) is your next best friend. This is a digital connection, so it's still miles better than analogue. It sends audio as light pulses, which is quite clever, really. Again, a half-decent cable is all you need. Plug it into the optical out on your TV and the optical in on your Vizio soundbar. You'll then need to go into your TV's audio settings and select "Optical" or "Digital Audio Out." You'll also need to make sure the TV is sending the right audio format. More on that in a moment. **A word of caution with optical:** it doesn't support the really high-res audio formats, and it won't let your TV remote control the soundbar volume directly. You'll have two remotes, which can be a bit of a pain. Still, it's a solid connection for most general TV watching. ### Analogue (3.5mm or RCA): Last Resort If you're stuck with analogue, either a 3.5mm jack or the red and white RCA cables, you're really limiting what your Vizio soundbar can do. This is an uncompressed signal, but it's prone to interference and generally just doesn't sound as clean or dynamic as digital connections. Only use this if your TV literally has no other options, which is pretty rare these days. ## Understanding Your Vizio Soundbar's Settings Right, now that it's connected properly, let's dig into the actual settings. Vizio soundbars, especially the 2.1 models, tend to have a similar set of options, though the names might vary slightly between models. Don't expect a massive graphical interface; it's usually just an LED display or a few lights telling you what's what. Most of these settings are accessed via the soundbar's remote control. Keep that little plastic thing safe; you'll need it. ### **1. Input Selection** Obvious, I know, but make sure you've selected the correct input on the soundbar itself. HDMI ARC, Optical, Bluetooth, AUX – match it to how you've connected it to your TV. ### **2. Audio Format (PCM vs. Bitstream/Dolby Digital)** This is a big one, often overlooked. Your TV sends audio in a specific format, and your soundbar needs to understand it. For 2.1 systems, you'll mostly be dealing with: * **PCM (Pulse Code Modulation):** This is an uncompressed stereo signal. Your TV decodes the audio and sends it as raw, uncompressed stereo to the soundbar. It's usually a safe bet and often sounds very good, especially for music. * **Dolby Digital (Bitstream):** This is a compressed digital audio format, commonly used for TV broadcasts and older DVDs/Blu-rays. Your soundbar then decodes it. Some soundbars prefer to decode it themselves. **My advice?** Start with **PCM** on your TV's audio output settings. See how it sounds. If you find dialogue is a bit thin or effects aren't punchy, try switching your TV to output **Dolby Digital (Bitstream)**. Some Vizio soundbars handle Dolby Digital decoding quite well, creating a slightly wider soundstage even with just two main channels and a sub. For 2.1, you're not getting full surround anyway, so PCM is often the cleaner choice. *Never* set your TV to output DTS for a basic 2.1 soundbar, unless it explicitly supports it (which most 2.1 Vizios don't). You'll just get silence or garbled noise. ### **3. EQ Presets (Movie, Music, Direct, TV, etc.)** Most Vizio soundbars come with some pre-programmed equaliser (EQ) settings. These are designed to give you a quick improvement for different types of content. * **Movie:** Usually boosts bass and treble for more impact in explosions and clear dialogue. Can sometimes sound a bit unnatural or boomy. * **Music:** Often aims for a flatter, more balanced frequency response. Good for listening to tunes, but might lack a bit of punch for films. * **Direct/Flat:** Bypasses any processing and tries to reproduce the sound as accurately as possible. A good starting point for your own adjustments. * **TV/Standard:** A general-purpose setting. Often a bit middy and safe. I usually start with **Direct or Music** and then tweak from there. Movie mode can be a bit much for me, making dialogue sound a bit masked by effects. Your mileage will vary, of course. ### **4. Bass and Treble Controls** Now we're getting into the nitty-gritty. Most Vizio soundbars will have separate controls for Bass and Treble. These are your most powerful tools for customising the sound to your room and taste. * **Bass:** This controls the low frequencies, where your subwoofer does its heavy lifting. Too little, and everything sounds thin. Too much, and it'll be boomy, muddy, and might annoy the neighbours. I usually start around the middle, then play some music with a good bassline or a film scene with explosions. Turn it up gradually until the bass feels present and powerful, but not overwhelming or drowning out the mid-range. Be wary of reflections in your room; a concrete wall behind the sub can make it sound much louder than it is. * **Treble:** This handles the high frequencies – cymbals, dialogue clarity, sparkling effects. Too low, and everything sounds dull or muffled. Too high, and it can become harsh, fatiguing, or sibilant (hissy "s" sounds). Again, start in the middle. Listen to dialogue. Is it clear? Are cymbals crisp? Adjust up or down until it sounds natural and detailed without being shrill. A good test is listening to a female vocalist; too much treble can make their voice sound thin. ### **5. Subwoofer Level/Gain** Your 2.1 system includes a separate subwoofer, which is responsible for those deep rumbles and thumping bass. Getting its level right is crucial for a balanced sound. It usually has its own control on the remote, separate from the main bass control. Think of it this way: the bass control adjusts the low end from the *soundbar itself* and how it integrates with the sub. The subwoofer level control adjusts the *overall output* of the subwoofer. You want the subwoofer to blend seamlessly with the soundbar, not stick out like a sore thumb. My typical approach: set the soundbar's main Bass control to halfway (or a tiny bit above). Then, play some varied content – music, movies, dialogue. Adjust the subwoofer level up until you *just* start to notice its contribution. Then, turn it down a notch or two. You want to *feel* the bass and have it underpin the sound, not hear it as a separate unit. If you can distinctly hear the subwoofer as a separate sound source, it's probably too high, or you need to try moving it around the room. Placement matters a lot with subs! ### **6. Dialogue Enhancer/Clear Voice** Many soundbars, Vizio included, have a setting specifically designed to boost dialogue clarity. If you find yourself constantly reaching for the remote during films because you can't hear what people are saying, this setting is for you. It typically focuses on the mid-range frequencies where human voices reside. Use it sparingly, though. While it can make voices clearer, it can sometimes make the overall sound a bit unnatural or 'boxy'. Try turning it on low first. If it helps without messing up the rest of the sound, great. If not, maybe leave it off and try to achieve dialogue clarity through careful adjustment of the main treble and bass settings instead. ### **7. Surround/Virtual Surround/DTS Virtual:X** Some Vizio 2.1 soundbars, especially the newer ones, might boast virtual surround sound technologies like DTS Virtual:X. Now, let's be realistic: a 2.1 system isn't going to give you true 5.1 or 7.1 surround sound. It simply hasn't got the physical speakers for it. What these technologies *try* to do is create a wider, more immersive soundstage by manipulating the phase and timing of the audio. Sometimes it works a treat, making the sound appear to come from wider than the soundbar itself. Other times, it can sound a bit echoey, phasey, or just plain weird, making dialogue sound diffuse. My recommendation is to try it. Turn it on for a bit, watch a film, listen to some music. Then turn it off. Which do you prefer? For music, I almost always prefer it off; I want a clear stereo image. For films, it might add a bit of ambience. It's a personal preference, so experiment. ### **8. Night Mode/Dynamic Range Compression** If you live in a flat or have sleeping family members, Night Mode is your friend. What it does is compress the dynamic range of the audio. This means it makes the loud bits quieter and the quiet bits louder. Explosions won't shake the foundations, and whispered dialogue will still be audible without cranking the volume right up. It's not for critical listening, as it undeniably flattens the sound. But for late-night viewing, it's a godsend. Vizio might call it "Night Mode" or something similar; check your manual. ## Room Acoustics and Speaker Placement: More Important Than You Think All the settings in the world won't fix genuinely bad room acoustics or terrible placement. Think of your room as part of the sound system. Every wall, piece of furniture, and curtain will reflect or absorb sound. ### Soundbar Placement * **Centred:** Ideally, your soundbar should be centred directly below your TV screen. This helps anchor dialogue to the picture. * **Unobstructed:** Don't stick it in a cabinet or behind anything. It needs a clear path for the sound to reach your ears. * **Ear Level (ish):** If possible, try to get it roughly at ear level when you're sitting on your sofa. If it's too low, the sound can feel disconnected from the screen. ### Subwoofer Placement This is where things get really interesting. Bass frequencies are omnidirectional, meaning they spread out in all directions. So, in theory, you can put a subwoofer anywhere. In practice, it's not that simple. Your room will have peaks and troughs in the bass response due to standing waves. * **The "Subwoofer Crawl":** This is a classic trick. Place your subwoofer in your main listening position (where your head usually is on the sofa). Then, play some bass-heavy music or a test tone. Now, crawl around the room on your hands and knees (you'll look daft, but trust me). Where the bass sounds smoothest and most even, that's a good spot for your subwoofer. Move it there. * **Corners vs. Walls:** Corners often boost bass (the "corner loading" effect), sometimes too much, making it boomy. Placing it against a wall can be a good compromise. Experimentation is key. * **Avoid Cabinets:** Don't shove your sub inside an enclosed cabinet. It needs room to breathe, and you'll get horrible resonance. ## A Note on Calibration (If Your Vizio Has It) Some higher-end Vizio soundbars might have a basic room calibration feature, often involving a microphone. If yours does, definitely use it. These systems send out test tones and listen to how your room responds, then automatically adjust levels and EQ to compensate for room acoustics. It's not as sophisticated as, say, Audyssey on an AV receiver, but it can make a noticeable difference. Follow the instructions in your manual carefully. Make sure the room is quiet during calibration. ## Real-World Scenarios & My Two Cents I've had a few Vizio 2.1 systems come through the SpeakersMag workshop over the years, usually the Vizio V-Series or M-Series 2.1 bars. They're never going to compete with a proper separates system, or even a £500+ soundbar from the likes of Sennheiser or Sonos. But for the money, especially if you snagged one for £150-£250, they do a job. For general TV viewing – news, soaps, the odd documentary – they're a massive step up from most TV speakers. Dialogue is clearer, and you get a bit of bass. That's all most people really want, isn't it? When it comes to films, you can usually get a decent amount of oomph from the subwoofer, but don't expect pinpoint directional effects. Explosions will rumble, but you won't feel like the helicopter is flying over your head. It's more about adding weight and impact. Music is where they sometimes fall a bit flat. That's true for most soundbars, mind you. They're designed more for cinematic content. If music is your main thing, you're better off with a good pair of stereo speakers and a dedicated amp. But if you're just having some background tunes while you're pottering about, a Vizio 2.1 can be perfectly acceptable with the Music preset and careful bass/treble/sub adjustments. ### **My Personal Setup for a Vizio 2.1 (for a typical living room):** * **Connection:** HDMI ARC (always). * **TV Audio Out:** PCM (usually cleaner, less compression artefacts). * **Soundbar EQ:** Start with "Direct" or "Music". * **Bass:** +2 to +4 (depending on room). I like a bit of warmth. * **Treble:** +1 to +2 (just to open it up a touch). * **Subwoofer Level:** Play with it until it blends, usually somewhere around -2 to +1 from default. You want to feel it, not hear it as a separate speaker. * **Dialogue Enhancer:** Off, unless I'm really struggling with a particular film. * **Virtual Surround:** Off for music, maybe on low for films if it doesn't sound odd. * **Night Mode:** On for late-night movie sessions, definitely. This isn't a magic formula, mind. Every room is different, every ear is different. But it's a solid starting point for you to fiddle about with. ## Who It's For: * Folks upgrading from dreadful built-in TV speakers. * Budget-conscious buyers who want better film impact and clearer dialogue. * Anyone looking for a simple, all-in-one sound solution for a smaller living room or bedroom. * Those who occasionally listen to music but prioritise TV and film sound. ## Who Should Skip It: * **True hi-fi enthusiasts:** You'll be disappointed. This isn't for critical listening. * **Anyone wanting true immersive surround sound:** A 2.1 system just can't do it, virtual or not. * **People with very large, open-plan living spaces:** A 2.1 Vizio might struggle to fill a huge room with sound. * **Those who demand extensive connectivity and advanced features:** Look at higher-end soundbars or AV receivers. ## Comparison: Vizio 2.1 Models (General)** | Feature | Vizio V-Series 2.1 (e.g., V21-H8) | Vizio M-Series 2.1 (e.g., M21d-H8R) | Vizio Elevate 5.1.4 (for context) | |:------------------|:----------------------------------|:------------------------------------|:----------------------------------| | **Price (approx)**| £150 - £250 | £250 - £350 | £700 - £900 (often cheaper now) | | **Subwoofer** | Wired (usually 5-6.5") | Wireless (usually 6-7") | Wireless (8") | | **HDMI ARC/eARC** | Yes (ARC) | Yes (ARC or eARC) | Yes (eARC) | | **Bluetooth** | Yes | Yes | Yes | | **Virtual Surround** | DTS Virtual:X (on some) | DTS Virtual:X | DTS:X, Dolby Atmos | | **Dedicated Centre** | No (phantom) | No (phantom) | Yes | | **Voice Clarity** | Basic Dialogue Enhancer | Improved Dialogue Enhancer | Dedicated Centre, clearer voices | | **Best Use Case** | Budget upgrade, TV/Film | Better all-rounder, slightly bigger rooms | True immersive cinema at home | *(Note: Prices are estimates and vary wildly. Specific features depend on the exact model number.)* ## FAQ: Getting Your Vizio 2.1 Soundbar Just Right ### Q: Why does my Vizio soundbar randomly switch inputs or turn off? A: This is often down to HDMI CEC (Consumer Electronics Control) being a bit too enthusiastic. While it's handy for single-remote control, it can cause glitches. Try disabling CEC features (like "Auto Power On" or "Input Change") on either your TV or the soundbar, or both, and see if it stops. Sometimes it's a bit of a cat-and-mouse game to find the culprit. ### Q: My subwoofer sounds boomy and indistinct. What's wrong? A: Firstly, check the subwoofer level; it's probably too high. Turn it down a few notches. Secondly, consider its placement. A corner can overemphasise bass. Try moving it a foot or two out from the wall, or try the "subwoofer crawl" method I mentioned earlier. Also, make sure the soundbar's main Bass control isn't maxed out. ### Q: Why is dialogue muffled, even with the Dialogue Enhancer on? A: This could be a few things. First, ensure your TV is outputting **PCM** or **Dolby Digital**, not DTS, as some Vizio 2.1 bars won't decode DTS. Second, try adjusting the soundbar's Treble control up slightly. Sometimes the Dialogue Enhancer can be a bit heavy-handed, so try it off and use Treble/Bass to fine-tune. Lastly, make sure the soundbar isn't tucked away in a cabinet or blocked by anything in front of it. ### Q: Should I use Bluetooth for TV audio? A: Generally, no. Bluetooth introduces a slight delay (latency) and compresses the audio, which isn't ideal for TV or film as it can lead to lip-sync issues and poorer sound quality. It's fine for background music from your phone, but for TV, stick to HDMI ARC or Optical for the best experience. ### Q: My Vizio soundbar sounds great for movies but awful for music. Any tips? A: Most soundbars are optimised for movie soundtracks. For music, try switching the EQ preset to "Music" or "Direct." Turn off any virtual surround modes. You might find you need to slightly reduce the Bass and Subwoofer levels compared to your movie settings, as music generally benefits from a more balanced, less boomy low end. Treble might also need a slight boost for clarity. ## Final Word There you have it. Getting the best out of a Vizio 2.1 soundbar isn't rocket science, but it does require a bit of patience and a willingness to faff about with the settings. Don't just plug it in and hope for the best. Spend half an hour running through these tips, listening to a bit of everything you normally watch or listen to, and I guarantee you'll get a sound that's a darn sight better than out of the box. Remember, your room, your ears, and your content are all unique. What sounds brilliant to me might sound a bit off to you, so don't be afraid to experiment. These Vizio bars, especially for the price, can be decent little performers if you give 'em a chance. Now, off you go, get tweaking!
