About the Yamaha YAS-108

A "bang for your buck" champ from Yamaha

Our customers were consistently shocked at the quality of sound they got from the previous version of this budget-friendly sound bar. Reviewers had many different ways of saying it should probably cost a lot more. I recently got to hear Yamaha's updated YAS-108 in person, and I was also astounded by the rich, full-range sound it put out. Its DTS Virtual:X processing did a great job of filling our cavernous vendor training room with simulated surround sound.

A "bang for your buck" champ from Yamaha

Our customers were consistently shocked at the quality of sound they got from the previous version of this budget-friendly sound bar. Reviewers had many different ways of saying it should probably cost a lot more. I recently got to hear Yamaha's updated YAS-108 in person, and I was also astounded by the rich, full-range sound it put out. Its DTS Virtual:X processing did a great job of filling our cavernous vendor training room with simulated surround sound.

Onboard amplification powers six drivers, including a pair of built-in ported subwoofers that deliver more bass than you'd expect from such a slim bar, especially at this price point. But if you want even more low-end rumble, there's a dedicated output for adding on a separate powered sub.

How does DTS Virtual:X work?

Many sound bars simulate Dolby Atmos or DTS:X by bouncing sound off your walls and ceiling. That's not what's happening here. The drivers inside the YAS-108 sound bar are slightly angled, but they're placed more or less where you'd expect to find them in two-channel bar. There are no upward-firing drivers. Instead, DTS Virtual:X almost completely relies on digital sound processing.

DTS uses what they call "spatial audio techniques" to make it seem like the sound is all around you. Incredibly sophisticated audio delays and adjustments create a larger, wider soundstage. That includes overhead atmospheric effects like leaves rustling on a tall tree or birds chirping above.

Check out Jeff Miller's article "What is DTS Virtual:X?" for more details.

Don't miss a word

Sometimes I have to rewind movie and TV shows because I didn't catch what the actor just said, and I'm sure I'm not alone. It can be hard to hear dialogue over the background noise. That's where Yamaha's Clear Voice processing comes in handy — it brings speech to the forefront so that dialogue is easier to hear and understand.

Stream your favorite tunes

Built-in Bluetooth makes it easy to stream your favorite tunes. You can wirelessly connect up to two compatible devices at once for quick switching between them. And if you have an Alexa-enabled device, you can pair the YAS-108 to that with Bluetooth, too.

Product Research


2.1ch Active Soundbar Speaker: The Yamaha YAS-108 active soundbar speaker features a 2.1ch driver configuration with one 1" dome tweeter and one 2.125" mid-woofer for each of the left & right channels, as well as dual 3" subwoofers for the LFE channel. The YAS-108 delivers 120-watts of power to the enclosed drivers - 30 watts to each of the left & right channels and 60 watts to both subwoofers.

Built-In Subwoofers w/ Bass Extension: The YAS-108 is equipped with dual, built-in 3" subwoofers plus a unique bass reflex port and "Bass Extension" processing to deliver exceptional low-end performance without the need for a separate powered subwoofer. You can adjust the level of the built-in subwoofers independently from the soundbar's overall volume.

Clear Voice: Clear Voice raises the level of dialog and narrations while maintaining overall sound quality. Movies and TV shows, sports commentary and news broadcasts are more clearly audible.

Compressed Music Enhancer: The Compressed Music Enhancer restores frequency response lost during digital compression, so your music sounds the way it should. Optimized for Bluetooth audio transmission, you'll enjoy vivid, lively sound quality during wireless playback. When a compressed source is played, the Compressed Music Enhancer engages automatically.

Dolby Digital & DTS Compatible: The Yamaha YAS-108 soundbar decodes 2ch PCM, multi-channel PCM, Dolby Digital, & DTS audio signals. You can listen to these audio formats in Virtual Surround mode or 2ch Stereo mode. The 2ch Stereo mode is ideal for music, while the Virtual Surround mode provides a much more immersive soundfield for movies. From Yamaha's Home Theater Control App on your Apple iOS or Android device you select between different surround modes - TV Program, Stereo, Movie, Music, Sports, & Game.

Digital Audio Connector Audio Signal Type Audio Signal Format
HDMI Multichannel PCM 2ch-6ch, 32-192kHz, 16/20/24-bit
Bitstream Dolby Digital, DTS
Optical 2Ch PCM 2ch, 32-96Hz, 16/20/24-bit
Bitstream Dolby Digital, DTS

DTS Virtual:X + 3D Surround: The YAS-108 can deliver immersive 3D surround sound, simulating sound effects that seem to move around the listener and even have a sense of height. Thanks to DTS Virtual:X & 3D Surround the YAS-108 allows surround sound to be heard not only from horizontal directions, but also from varying heights. DTS Virtual:X can be used with any content (from 2ch to 5.1ch soundtracks), while delivering virtual height & virtual surround processing based on psychoacoustics (not reflective surfaces).  Ideal for use with any multichannel content (including DTS- and Dolby-encoded soundtracks) it creates more spacious, lifelike sound for all of your favorite TV shows, movies and games.

HDMI 2.0b: The Yamaha YAS-108 is outfitted with one HDMI input and one HDMI ARC output that support the latest HDMI 2.0b standards; such as 4K/60Hz, HDCP 2.3, 4:4:4 color subsampling, & HDR (High Dynamic Range) for full support of today's 4K content from Ultra HD Blu-ray & online video services (like Amazon & Netflix).

  • 4K/60HZ + HDCP 2.3: The YAS-108 supports up to 4K (3840x2160 pixels) video @ 60 frames per second through its HDMI input and output. The HDMI input and output is HDCP 2.3 certified (available firmware update), which fully complies with the latest copyright protection standard for 4K video transmission. It also supports a 480i, 480p, 720p, 1080i, or 1080p video signal.
  • 4:4:4 Color Subsampling: In addition, the HDMI input and output support RGB, YCbCr 4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, 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 colors, plus greater color accuracy and detail.
  • Deep Color & x.v.Color: The soundbar's HDMI jacks support Deep Color & x.v.Color content, which can display a larger color range than standard-definition schemes. The result is a more lifelike, vibrant picture.
  • 3D Ready: The YAS-108 soundbar supports 3D video pass-through (720p/1080p only) from connected 3D-compatible Blu-ray, games and broadcast devices to 3D-compatible HDTVs (all 3D components must be connected via HDMI). Special eyewear will be required for viewing 3D content.

High Dynamic Range: High Dynamic Range video provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. The YAS-108 supports HDR 10 and HLG.

  • HDR 10: HDR 10 is an open standard and currently the most popular HDR format on the market. 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.
  • HLG: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.

ARC (Audio Return Channel): This feature of the YAS-108's HDMI output allows audio to be sent from your compatible TV to the soundbar through the same HDMI cable already being used to send audio and video to your TV. This eliminates the need for extra cables connected to your television.

Note: Because with some televisions, the ARC-enabled HDMI input will only pass 2ch PCM from devices connected to the TV via HDMI or analog, we recommend that you connect your Blu-ray player or  Satellite/Cable box to the Yamaha soundbar directly; and then connect the YAS-108's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance.

Analog & Digital Audio Inputs: The YAS-108 is outfitted with both analog & digital audio outputs to connect to your TV. There is one optical (toslink) digital input that supports 2Ch PCM, 5.1ch Dolby Digital, and 5.1ch DTS audio signals (up to 24-bit/32-48kHz). There is also one stereo minijack (3.5mm) audio input for televisions without an optical digital out.

Note: The digital optical output terminals of some flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby Digital/DTS surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or satellite/cable box).

Bluetooth Audio Streaming: The Yamaha YAS-108 soundbar speaker system supports Bluetooth (v5.0)  A2DP wireless audio streaming (up to 33'). This allows you to stream stored music and music apps from your Bluetooth-enabled device; such as your Apple iPod/iPhone/iPad, Android smartphone/table, Windows Phone/PC, or Mac computer/laptop to the YAS-108 soundbar speaker. You will continue to navigate your music and view song/artist information from your Bluetooth-enabled device.

  • Dual Device Connection: The YAS-108 allows you to wirelessly pair and connect two Bluetooth source devices, so you can switch easily back and forth between devices and music libraries.
  • SBC + AAC Codecs: In addition to support for the standard SBC Bluetooth audio codec, the Yamaha soundbar speaker offers support of AAC. By supporting AAC, the YAS-108 soundbar offers better audio performance of the music streamed from your Apple iPod, iPhone, or iPad.
  • Bluetooth Standby: The Bluetooth Standby function allows you to turn On or Off the soundbar automatically, linked with the operation of a Bluetooth device.
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the Yamaha YAS-108.

Sub Out: A mono-RCA subwoofer output lets you hook up an optional powered sub (sold separately). The soundbar's built-in subs will continue to produce sound along with the external power sub.

IR Remote w/ HDMI-CEC: The YAS-108 comes with a sleek, easy-to-use IR remote control for wireless operation of the soundbar speaker. Also, if your TV supports HDMI CEC and uses HDMI connectivity, it is possible to adjust the volume of the sound bar using your TV's remote to simplify day-to-day operation.

Note: This soundbar does not allow you to program your TV remote to operate the speaker, but does offer HDMI control through your compatible TV's remote.

Home Theater Controller App: The YAS-108 is compatible with Yamaha's Home Theater Control App (HT Controller) for Apple iOS 9.0+ & Android OS 4.0+ devices. This remote app makes it easy to control the soundbar from your compatible Apple iOS or Android device via a Bluetooth connection. Its intuitive and easy-to-see operating screen uses icons that let you easily perform a variety of operations; including Input, Volume, Audio settings, and Surround modes. Surround modes include TV Program, Stereo, Movie, Music, Sports, & Game.

Mounting Options: Due to its slim profile, the soundbar fits in front of most flat-panel TVs without blocking the screen. If you prefer to wall-mount the speaker, the YAS-108 offers built-in keyhole slots (spaced 18" apart). A built-in gyroscope optimizes sound depending on whether the soundbar is placed on a table-top or hung on wall.

  • Table-Top Dimensions: 34.9375" (w) x 2.1875" (h) x 5.1875" (d)
  • Wall-Mount Dimensions: 34.9375" (w) x 5.1875" (h) x 2.1875" (d)

Auto Power Standby: When the Auto Power Standby function is enabled, the unit will automatically turn off when there is no operation for 8 hours. When Bluetooth or HDMI is selected as the input, the unit will turn off after no audio input and no operation for 20 minutes.

Customer Q&A

12 questions already asked

can you connect the Soundbar to a receiver via ARC so that my dvd and Apple TV (connected to receiver) will also output sound to Soundbar?
[ Boba  Sep 22, 2019 ]
2 answers
A receiver is made to send video out from HDMI, and the ARC is made to receive audio. You would not be able to get the audio from the receiver to the soundbar or TV, as the receivers main job is to process the audio, it doesn't send the audio via HDMI. In short, soundbars and receivers don't really work well together, as they are both designed to do the same thing. It's generally an either/or scenario.
[ Calvin  Oct 03, 2019 ]  Staff
I connected my PS3 to my Soundbar via ARC, so I would imagine the dvd would not be a problem. I have never used Apple TV, but if the connections are compatible, it should not be a problem. I control all volume through the Yamaha remote.
[ Eric  Oct 02, 2019 ]
Is the YAS-108 sound bar compatible with my 2014 Samsung smart tv (un40h6350af)?

If the tv has a digital to analog connection or hdmi , it should work. Right now I have it connected to a very old plasma but it has the TOS link connection and works great.
[ Nancy  Sep 16, 2019 ]
[ Janis  Sep 15, 2019 ]
It should work with your tv unless your tv doesnt have hdmi but can probably hook it up another way
[ RON  Sep 15, 2019 ]
Do I need to hook up optical cable as well as high speed HDMI for ARC to work and sound to come out? I am getting ARC control on/off and see lights flashing for volume up/down but no sound.

I had the same problem when I bought mine. I traced it to usage of an old HDMI cable. I bought a new one with the latest specs and that fixed it. I do not use an optical cable.
[ Paul  Apr 14, 2019 ]
You should not need to connect the optical cable as well as the HDMI cable. Sometimes you may need to reboot (unplug and plug-in the power line to) the television. I have found this to be true with a Sony TV.
[ Wayne A.  Apr 12, 2019 ]

From https:// Note: Because with some televisions, the ARC-enabled HDMI input will only pass 2ch PCM from devices connected to the TV via HDMI or analog, we recommend that you connect your Blu-ray player or Satellite/Cable box to the Yamaha soundbar directly; and then connect the YAS-108's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance. [But this is only if I'm watching a video from those devices, correct? If I watch a video from Roku, which is built-in to my TV, or over the air HDTV, I may hit this 2 ch PCM limitation?]

Since those two are abilities built into the TV and not connected to the TV using an HDMI cable, then this message does not apply. Those built-in abilities have been able to pass mulitchannel audio (when available with the content you are watching) through the HDMI ARC connection My Bio:

If mounted on the wall, will the spacers allow the wires to go behind the bar? Would like to mount above the tv and have the wires go down behind.
[ Bradley  Dec 28, 2018 ]

Yes, there's just enough gap for you to route/rest some cables behind the wall mounted speaker (maybe not those super thick gauge HDMI cables though...)
[ Andy  Dec 30, 2018 ]
Yes yes yes yes! That is exactly as we have it setup in the bedroom. Spacers do the job perfectly and the wires hang down behind into their respective inputs. I also paired this wonderful soundbar with a mini REL subwoofer and the bedroom sounds like a theatre room. Great for small to medium bedrooms.
[ PAUL  Dec 28, 2018 ]
It should allow you to run wires behind the soundbar i didn't put my soundbar on the wall good price
[ RON  Dec 28, 2018 ]
If you mount the bar directly above the TV you should be able to come down behind the TV from behind the soundboard Enter an answer to this question.

Is there a wireless subwoofer that I could add to this bar? I see that it has subwoofer out connectivity, but I don't want wires. Basically, I want the equivalent to the YAS-207 but with this bar.

I have 12 jbl and 8 hk get the 12 jbl
[ james  Sep 26, 2018 ]
It does not have a wireless subwoofer. There is a connection to add one, but, not wirelessly. While it does sound pretty nice it lacks deep bass. If you want more bass you may want to look at the YAS-207 as an alternative. Depending on your budget you could look at the YAS-706 which has a wireless sub and has a music cast system.
[ kurt  Sep 07, 2018 ]
I purchased the sound bar without a subwoofer. The unit itself has very strong bass. I would not spend more for a subwoofer. Try it alone first.
[ JAMES R  Sep 06, 2018 ]
Which mounting orientation is more optimal? This is a gift for a woman who is slightly hard of hearing, and her current stock TV speakers are very muddy and vocals are not clear. We have the option of installing this either on the table or on the wall. Based on driver location, which option would be better for vocal sound quality?
[ CHARLES  Sep 05, 2018 ]

I have a slight hearing loss in one ear and also found voices to be unclear from my TV speakers. My soundbar is on a 29'' high TV stand and I can now hear voices with no problem. Mounting it on a wall might be better, but the table works well enough for me that it wasn't necessary.
[ Paul  Sep 10, 2018 ]
For someone who is slightly hard of hearing I would install it on the table-top option facing the listener. A better option (your loved one will feel like she has perfect hearing) would be what I did for my father who is almost completely deaf, and that is purchase the Sennheiser RS 175 wireless headphones. Amazing sound and she won't miss a thing. Just make sure her tv has an optical cable input. Hope this helps.
[ PAUL  Sep 10, 2018 ]
If mounted on a wall, the drivers will be facing the audience. If placed on a table, the drivers will be facing up.
[ Peter  Sep 10, 2018 ]
Mounted on the wall would produce the best sound quality so that there is nothing obstructing the sound and if possible might even be better if it was mounted about the TV for someone hard of hearing.
[ Melinda  Sep 10, 2018 ]
Your better to put on the wall
[ RON  Sep 10, 2018 ]
For me, I think you'd have to mount it to a wall as opposed to laying it flat. In addition to the sound projecting better from that position (IMO), you can see the indicator lights better.
[ Andy  Sep 10, 2018 ]
We have ours on the table in front of the tv. Possibly on the wall facing forward would be better, but too little difference to matter, in my opinion. BTW, I like the simplicity of the connectivity, and the sound is a big improvement, especially for speech.
[ William  Sep 10, 2018 ]
I tried both , I like the wall , better sound
[ Harry  Sep 10, 2018 ]
We have on the table and it works great. Use clear voice. Paul.
[ Paul  Sep 10, 2018 ]
Mount on wall with speakers facing forward. This also Gives you better control with your remote control. The clear voice works great.
[ HENRY  Sep 09, 2018 ]
