About the Definitive Technology Studio 3D Mini

Compact design, big sound

The innovators at Definitive Technology believe that you can have your cake and eat it too: a sound bar can be packed with lots of great features and small enough to blend into your room and keep a low profile.

Compact design, big sound

The innovators at Definitive Technology believe that you can have your cake and eat it too: a sound bar can be packed with lots of great features and small enough to blend into your room and keep a low profile.

The Studio 3D Mini fits comfortably under almost any modern flat-panel TV, and its sleek, minimalist design means it practically fades into the background. At the same time, it delivers a deep, wide and dynamic sound that pulls you into the on-screen action.

Definitive Technology Studio 3D Mini sound bar system

The Studio 3D Mini brings surprisingly powerful sound for its size and is backed up by an 8" sub.

Virtual surround sound

This 4.1 sound bar system is compatible with Dolby Atmos and DTS:X soundtracks, and it simulates 3D surround sound using psychoacoustics. That's a fancy way of saying that the bar's advanced processing tricks your brain into thinking sound is coming from positions in your room where there aren't any speakers. This virtual approach creates the experience of height and rear sound effects. It's surround sound without installing speakers and running wire around your room. Seems crazy, but it's legit.

Connected with HEOS

The Studio 3D Mini has HEOS Built-in, allowing it to tie into a wireless multi-room audio ecosystem. If you have other HEOS-compatible speakers and components, you can connect them together via Wi-Fi and control music all around your house with an app on your phone. Play the same song everywhere at once, or different music in each room. The kids can listen to "Seagulls (Stop it Now)" in the living room while you jam to "Battle of Evermore" in the kitchen cooking dinner at the same time.

HEOS supports a ton of streaming services, all available through the app. It can even access songs you've collected on computers or networked hard drives. If that includes a stash of sweet hi-res music files, you're in luck. HEOS supports playback of files up to 24-bit/192kHz (5.6 MHz for DSD files).

More music options

You can stream audio from your phone straight to the sound bar via Bluetooth. Apple fans are in good hands with AirPlay 2 supported, which lets you stream from an iPhone® or iPad® and connect the sound bar to the AirPlay ecosystem. If you've got a thumb drive with music stashed on it, including high-res files, you plug it into the USB input on the back of the bar.

Stay in control

The Studio 3D Mini is compatible with Amazon Alexa, Google Assistant, and Siri (separate voice control assistant required). This lets you control the volume, skip tracks, and pause or unpause what's playing, with just the sound of your voice.

If you prefer a good old-fashioned remote, this system has you covered. If the remote and your phone surreptitiously find themselves lost in the cushions of your couch, never fear — there are controls on top of the sound bar itself too.

4ch Active Soundbar: The Definitive Technology Studio 3D Mini's active soundbar speaker employs a 4-channel configuration with a six-driver array, featuring two 1" aluminum dome tweeters, two front-firing 1" x 3” racetrack drivers, and two angled side-firing racetrack drivers for a wide, immersive soundstage from movies and music. The 4-channel configuration consists of Left & Right Front channels (front-firing) for the stereo and center information of a movie or music soundtrack, as well as Left & Right Surround channels (side-firing) for the Surround and and Surround Back information of a movie soundtrack. Virtual overhead height information from a Dolby Atmos or DTS:X movie soundtrack is matrixed between the soundbar's Front and Surround channel drivers.

  • The active soundbar speaker is slim and compact. It should be centered with your TV screen. The soundbar can be placed on a tabletop in front of your television, or wall-mounted below or above your TV using its integrated keyhole slots.
  • Because the active soundbar speaker has side-firing drivers, make sure it is not placed inside a cabinet that obstructs the sound output of these side-firing drivers.
  • The active soundbar speaker comes with a 6' AC power cord that will need to be plugged into an AC power outlet or surge protector (sold separately).

Note: The Definitive Technology Studio 3D Mini does not support wireless rear surround speakers.

8" Wireless Powered Sub: The Studio 3 Mini includes an 8" wireless powered subwoofer that receives its LFE (Low Frequency Effect) audio signal wirelessly from the system's active soundbar speaker. The powered sub's dowin-firing 8" long-throw woofer and down-firing port delivers deep and impactful bass for movies and music. You can adjust the level of the subwoofer independently from the active soundbar speaker.

  • The wireless powered subwoofer can be positioned practically anywhere in the room, up to 30' away from the soundbar.
  • Placing the subwoofer in a corner can make the bass seem even more pronounced.
  • Even though the powered sub is wireless, it still requires an AC power connecting using the included 6' AC power cord.

Note: The soundbar and subwoofer are wirelessly connected at the factory and work together right out of the box. If connection fails then you will need manually connect the soundbar and subwoofer (see owner's manual for details).

Virtual 3D Audio: The Definitive Technology Studio 3D Mini delivers immersive 3D surround sound, thanks to support of Dolby Atmos and DTS:X. It also features 3 Sound Modes to choose from - Movie, Music, and Night. Night mode makes audio easier to hear at lower volume levels. There is also a Dialog Enhancement features that enhances movie dialog and music vocals.

  • Dolby Atmos: Dolby Atmos surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the soundtrack designer the ability to precisely place sounds anywhere in the 3-dimensional space. The Studio 3D Mini is able to perform Dolby Atmos playback from a soundbar & subwoofer system using Dolby Atmos virtual height and virtual surround sound processing which creates a three-dimensions (3D) soundfield without having actual height or rear speakers. Non-Dolby Atmos content can even be enjoyed in virtual 3D sound thanks to Dolby Surround.
  • DTS:X: DTS:X is an immersive surround sound format featuring object-based audio coding that lets the soundtrack designer place sonic elements anywhere in the 3D acoustic soundspace to provide for overhead effects that deliver a stunning surround sound experience. The Studio 3D Mini uses DTS Virtual:X technology to create virtual height and surround sound channels from a soundbar and subwoofer without having physical overhead or rear speakers. DTS Virtual:X can even be used with non-DTS:X content, so you can still enjoy virtual 3D surround.

HDMI 2.0b: Featuring one HDMI input and one HDMI ARC output, the Studio 3D Mini incorporates an advanced video section that features the HDMI 2.0b specification; including support for 4K/60 Hz Ultra-HD video with HDCP 2.2 compatibility (a requirement for 4K Ultra HD copy-protected content), HDR (High Dynamic Range), and eARC (Enhanced Audio Return Channel). Use a premium High Speed 18Gbps HDMI cable for the best 4K/HDR performance.

  • 4K/60Hz + HDCP 2.2: The Studio 3D Mini supports up to 4K (3840x2160 pixels) video @ 60 frames per second via its HDMI input and output.. It will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI. There is no video resolution upscaling. All of the soundbar's HDMI jacks support HDCP 2.2, which fully complies with the latest copyright protection standard for 4K video transmission.
  • HDR (High Dynamic Range): The Studio 3D Mini supports High Dynamic Range video - including HDR10 and Dolby Vision. 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.
  • eARC (Enhanced Audio Return Channel): This feature of the Studio 3D Mini's HDMI output allows audio to be sent from your compatible TV to the speaker system 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. eARC (Enhanced Audio Return Channel) will support uncompressed audio formats like Dolby TrueHD, Dolby Atmos, DTS:X, & DTS HD Master Audio - where as the previous ARC (Audio Return Channel) was limited to only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

Note: If you connect to a TV that only supports ARC (Audio Return Channel), the soundbar's HDMI eARC jack will be limited to DTS, Dolby Digital, and Dolby Digital Plus. In some cases you may be able to get Dolby Atmos, if the TV offers Dolby Atmos via Dolby Digital Plus through its HDMI ARC jack. DTS:X and DTS-HD is not supported via HDMI ARC (must be HDMI eARC).

Analog & Digital Audio Inputs: In addition to HDMI connectivity, the Definitive Technology Studio 3D Mini is outfitted with digital and analog audio inputs.

  • Optical Digital: For TVs without eARC or ARC via HDMI, you can connect the Studio 3D Mini via its optical (toslink) digital audio input. The optical digital input supports 2ch PCM and 5.1ch Dolby Digital/DTS (up to 24-bit/96kHz). *The optical digital input is not compatible with Dolby Atmos or DTS:X.
  • 3.5mm Minijack: The included stereo analog minijack (3.5mm) input lets you connect the Studio 3D Mini to your TV without eARC/ARC or a digital output; or to a portable music player. This connection only supports 2ch PCM.
Note: The digital optical output 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).

USB Port: The Studio 3D Mini features a rear-panel USB (type-A) port that allows you to enjoy a variety of high-resolution and compressed music files from a USB mass storage class memory device, such as a USB thumbdrive (formatted in FAT 32 or NTFS). Listen to uncompressed WAV (PCM), ALAC (Apple Lossless Audio Codec), and FLAC (Free Lossless Audio Codec) music files up to 24-bit/192-kHz; as well as DSD (2.8/5.6MHz). HEOS is also compatible with compressed music files - such as MP3, WMA, and AAC (MPEG4). From the HEOS app on your Apple iOS or Android device you can browse music files, control playback and view song/artist information with album art. DLNA music content can be distributed to other HEOS products connected to your home network. USB portable audio devices that can be charged via USB will be charged when plugged into the speaker's USB port (5V/1A); even in standby mode.

Note: It is not possible to connect and use a computer via the USB port of this unit using a USB cable. The USB port does not support Apple iOS or Android devices. USB hubs and card-readers are not supported.

Wired or Wireless Network Connectivity: The Definitive Technology Studio 3D Mini can connect to your home's network via Ethernet (RJ-45) or dual-WiFi (802.11ac; 2.4GHz/5GHz). At least a dual-band (2.4/5GHz) "N" router is recommended for the most reliable wireless network connection for high-resolution music playback. The free HEOS app for Apple iOS and Android is used for wireless (WiFi) setup with your home's network. A wired or wireless network connection is required for HEOS Built-In, Apple AirPlay 2, and DLNA.

Note: A WiFi extender (sold separately) may be necessary if your network's wireless signal is weak to some of the HEOS speakers or players in your application.

HEOS Built-In

HEOS: The Definitive Technology Studio 3D Mini is part of the HEOS wireless multiroom audio eco-system - comprising of a family of wireless network speakers, AV receivers, amplifiers, & pre-amplifiers for your whole home. The HEOS system uses your home's wireless (WiFi) network for whole-house audio entertainment. There is a free HEOS app to control them from your Apple iOS or Android mobile device. You can enjoy your favorite streaming music services, internet radio, or your own music collection through out your home. Plus, set-up is intuitive and simple. To make HEOS wireless multi-room audio work in your home, you'll need -

  • HEOS network audio speakers, receiver amplifiers, and/or pre-amplifiers
  • a wireless (WiFi) home network with internet connection
  • an Apple iOS or Android mobile device connected to your home wireless (WiFi) network
  • the free HEOS app downloaded on your Apple iOS or Android device
Note: Prior to using the HEOS system, you'll need to setup up your free HEOS account. Your HEOS account remembers all your settings and preferences such as all your music service logins and HEOS playlists. When you'd like to add multiple smartphone or tablet controllers to your system, you only need to sign in to each new device with your HEOS user name and password. Instantly all your music services and HEOS playlists are available in the new controller too. If you prefer, multiple HEOS accounts can be setup in a single household. This way, each family member can enjoy their own personalized Pandora, Spotify, etc. account settings and still share all the same speakers in the home.

Online Music Services: With HEOS Built-In, you'll be able to stream your favorite online music service like Pandora, iHeart Radio, SiriusXM, Tidal, Amazon, Rhapsody, TuneIn, Spotify Connect, Amazon Music, and more. The HEOS app on your Apple iOS or Android device will serve as the controller for these apps and provide song/artist information with Album Art. You can create a "Favorite" station list, so you can quickly access your favorite internet radio stations and online music channels. These online music services can be distributed to other HEOS products connected to your home network.

  • Napster: Napster is a streaming music subscription service (starting a $10 per month) that allows you to play the full-length songs you choose on demand from a collection of over 10 million songs, without ads and without having to purchase or download the music.
Note: Availability of online music services may vary by region. Not all services may be available at time of purchase. Some services may be added or discontinued from time to time based on decisions of the music service providers or others.

Mobile Device Streaming: Using the HEOS app on your Apple iOS or Android mobile device, you are able to stream your device's stored music library to the Studio 3D Mini. You'll be able to browse your music library by Artist, Album, Genre, and Song; control music playback functions like Play/Pause and Previous/Next Track; and view song/artist info with Album Art from the app on your compatible mobile device. You can even type in an artist name or song title to find music in your mobile device's library.

  • Playlists: You can save the Now Playing queue as a HEOS Playlist that you can recall later. The new playlist will be available from the Playlists button on the Music tab on the HEOS controller app.
  • Music Sharing: The HEOS App also has a feature called "Music Sharing" which can share the local music stored on your mobile device to other HEOS app users on your home network. The name of the mobile device you are sharing from will appear as a new Local Music source allowing other HEOS controller apps to browse and play music on your device from their device.

Note: Your music must be physically stored on the device and not the cloud.

Multi-Room Configuration: Thanks to HEOS Built-In, the Studio 3D Mini can be integrated into a HEOS wireless multiroom audio eco-system, allowing you to stream and control all of your local and online music effortlessly from anywhere in your home with the HEOS App on your compatible Apple iOS or Android mobile device over a wireless WiFi network connection. The HEOS system is a true multi-room audio system that automatically synchronizes audio playback between multiple HEOS devices so that your music (up to 24-bit/192kHz Hi-Res audio) coming from different rooms is perfectly in sync and always sounds amazing. You can play the same audio source in every room or any combination of rooms you choose, including a different song in every room.

  • Hi-Res & Audiophile-Grade Synchronization: To deliver a true audiophile listening experience for high-resolution music playback (up to 24-bit/192kHz) with multiple HEOS speakers & receivers at once, each HEOS speaker and receiver must be synchronized to an extremely high degree. Based on years of meticulous research, HEOS delivers unparalleled synchronization performance within microseconds for exceptional high-resolution music playback.
    • HEOS Gen 2 (HS2) products, like the Studio 3D Mini, will distribute high-resolution music files (up to 24-bit/192kHz) throughout your home to other HEOS Gen 2 (HS2) product; without any down-sampling.
    • HEOS Gen 2 (HS2) products, like the Studio 3D Mini, will down-sample high-resolution music files (up to 24-bit/192kHz) to CD-quality (16-bit/44.1kHz) and then distribute the music throughout your home to older HEOS Gen 1 product
  • Systems & Groups: The HEOS wireless multiroom sound system can support up to 32 HEOS speakers, receivers, players, amplifiers, and/or pre-amplifiers (all sold separately) on a single wireless network (IEEE 802.11 g/n; 2.4/5GHz). You can join or group up to eight individual HEOS devices into a group that function as if they were a single source. The HEOS eco-system is flexible enough where you can create up to 16 Groups (2 Heos devices per Group). You can easily group 16 rooms together with Party Mode by simply using a "pinch" gesture.
  • Compatible Sources: The following sources can be distributed through the HEOS multi-room audio system -
    • Online Music services including Amazon, Pandora, Spotify, Tidal, SiriusXM, iHeartRadio, and Napster
    • Windows PC & DLNA music servers
    • Bluetooth & USB audio (AirPlay 2 is not supported)
    • Music libraries stored on your Apple iOS or Android mobile device
    • Digital & Analog inputs (including HDMI, Optical, and Minijack)

Notes: A Group refers to the HEOS App's ability to play multiple HEOS systems together, so you're simultaneously outputting the same source information from all the HEOS systems. Grouping the systems will also allow proper synchronization to all systems so you should never hear an audio delay between the HEOS systems.

AirPlay 2, DLNA, Roon, & Bluetooth

AirPlay 2 with Siri: AirPlay 2 is an advanced and easy-to-use wireless multiroom audio platform for iTunes, Apple Music, and other compatible Apple iOS apps. With AirPlay 2 you can play any audio from your Apple iOS device (running iOS 11.4 or later) or Mac computer (running OS X 10.13.2) on the Studio 3D Mini and other compatible AirPlay 2 speakers throughout your home. You can choose to play audio in one room, play the same audio in grouped rooms, or play the same audio in every room. If you are an Apple Music subscriber, you can even play different music in different rooms (you can control and group directly from Apple's Music App and Home app on your Apple iOS device). You'll be able to ask Siri-enabled devices (like your Apple iPhone, iPad, or Watch) to control playback of your Apple Music content on the soundbar & subwoofer system. You can even watch videos and movies from YouTube and Netflix on your compatible Apple iOS device or Mac computer with perfectly synced audio on the Studio 3D Mini.

DLNA Certified: The Definitive Technology Studio 3D Mini is DLNA (Digital Living Network Alliance) 1.5 and Windows 7/8 compliant. This allows you to wirelessly stream a variety of high-resolution and compressed music files stored on your network connected Windows PC or DLNA-certified NAS drives to the Studio 3D Mini.

Roon Tested: Roon is a feature rich music library and playback application that compiles all the music files available to your network and makes them easily available to play on the Definitive Technology speaker and any other Roon enabled audio devices. Roon manages digital music files (including FLAC, WAV, AIFF, ALAC, and DSD) collected on hard drives and networked storage devices. It can also integrate your iTunes library, and optionally merge with the Tidal and Qobuz music streaming services. Roon software can be installed on your Windows or Mac computer, while a Roon Remote app is available for Apple iOS 11.0+ and Android OS 5.0+). When you access the Roon software or remote app, it will display your complete audio library together with its metadata and artwork along with the available Defintiive Technology speaker and other Roon enabled devices. Simply select the music you wish to play and the Defintive Technology speaker or Roon device in which you want to hear it on.


  • To use Roon you will need a Roon Core running on the same network as the Definitive Technology speaker. The Core is media server software that runs on your computer, NAS, or component (like Nucleus or ROCK - sold separately), located on the network within your home.
  • Make sure your Denon product has the latest firmware/software update installed.

Built-in Bluetooth: The Denon DHT-S716H features built-in Bluetooth 4.2 with a 98.4' wireless range for music streaming (A2DP 1.2) and control (AVRCP 1.5). You'll be able to wirelessly connect to smartphones (including iPhone & Android), tablets (including iPad & Android), laptops (including Microsoft Surface & Macbook), computers (including Windows PC & Mac), and other Bluetooth-enabled devices. You can wirelessly stream stored music, music apps, and other audio content from your Bluetooth-enabled source device to the Denon active soundbar speaker. The Studio 3D Mini supports the Bluetooth SBC codec only. Up to eight Bluetooth devices can be remembered by the Studio 3D Mini, so family members as well as friends can enjoy their favorite tracks (only one device can be used at a time).

Note: Bluetooth pairing and wireless audio streaming can be done without a network connection or the HEOS app.

Simple Intuitive Control

Remote Control: The included IR remote provides wireless control of the soundbar and subwoofer speaker system. The remote operates Power, Source (TV/HDMI/Optical/Aux), Volume (System/Subwoofer), Mute, Sound Modes (Movie/Music/Night), Dialog Enhancement, and Bluetooth Pairing. The Studio 3D Mini also supports HDMI-CEC, multibrand TV control, and remote learning functionality.

  • HDMI-CEC: When connected to a TV that also supports HDMI-CEC, you can perform basic soundbar operations (changing the input source, turning the power on and off, and adjusting the volume) with the remote control from your TV.
  • Multibrand Preset: Thanks to built-in preset codes, you can control the volume of the soundbar system from the remote of multiple brands of TVs (including Sony, Samsung, and LG). This is useful when your television does not support HDMI-CDC, or when you connect to a television that does not have HDMI.
  • Remote Learning: If your TV does not support HDMI-CEC and the preset remote codes do not work, you can use the Studio 3D Mini's remote control "learning" function to "teach" your TV's remote to control the soundbar system (including Power and Volume). The Remote Learning function is configured through the HEOS app.

Note: The HEOS app (for Apple iOS and Android OS) is required to access HEOS Built-In, AirPlay 2, and DLNA.

HEOS App: You'll need to download the HEOS App (for Apple iOS 9.0+ and Android OS 5.0) onto your compatible Apple iOS or Android mobile device. The app is required and provides everything you need to set up and enjoy music on the HEOS system. Using your mobile device and the HEOS app, you can setup, browse, explore, and control HEOS system right in the palm of your hand, from anywhere in your home.

  • Rooms: From the app on your Apple iOS or Android device, you can select which rooms you want playing. You can play the same music in multiple rooms by grouping rooms together, or you can listen to a different source in each room.
  • Music/Sources: You can select what music and which source you want to listen to from the app. Choose from online music services like Pandora, Spotify, TuneIn, Tidal, etc.; your music library on your Apple iOS or Android device, Windows PC/DLNA server, or USB thumbdrive; and HDMI, Optical digital, or Aux inputs; as well as Bluetooth on the Studio 3D Mini. You can also select music from Playlists you've created, Favorites you've saved, and your recent listening History.
  • Now Playing: The "Now Playing" screen displays song, artist, and album information; along with Album Art. You also get basic playback controls like Play/Pause and Previous/Next Track, plus Volume controls Up/Down and Mute. In addition the "Now Play" screen functions unique to the selected online music service or music library.

Alexa Compatible: HEOS and Amazon Alexa customers can now enjoy the convenience of Alexa voice control plus high-quality wireless home audio. In addition to controlling your HEOS components with the HEOS app on your mobile device or tablet, you can now control them with Amazon Alexa voice technology and an Amazon Alexa device (such as the Echo or Echo Dot, sold separately). Your HEOS components and the Alex-enabled devices must be on the same network. Voice control features include -

  • Alex voice commands include Volume (up/down, specific volume number, & mute); Playback (Play, Pause, Stop, Next, Previous, Resume); and Power on/off. And thanks to the latest firmware update, you can even use Alexa to switch inputs on HEOS enabled AV receivers and soundbars.
  • You can group your HEOS-enabled devices using the HEOS app with an Alexa-friendly name. Once they are grouped, Alexa voice commands will control the group as a whole. If you want to play audio content from only one HEOS-enabled device in the group, you must ungroup the device within the HEOS app.
  • You are able use voice commands to search for songs, albums and artists and even podcasts and internet stations from HEOS & Alexa compatible music apps - like Amazon Music, Pandora, TuneIn, iHeartRadio, Spotify Connect, & SiriusXM.

Google Assistant Support: Ask your Google Home, the Google app (for Apple iOS 11.0+ and Android OS 5.0+), or other devices with Google Assistant built-in to control HEOS content across your listening environment. Once you start music in the HEOS app, you can ask the Google Assistant to control volume, play, pause, skip tracks, and more. Once you have grouped your HEOS-enabled devices using the HEOS app, you can use the Google Assistant and voice commands to control a group of HEOS devices as a whole. Make sure the unit has the latest HEOS software and firmware update installed.

  • A future firmware update (no ETA) will allow you to use the Google Assistant and your voice to queue up music services, power on/off devices, switch inputs and more.

Can you hook up def tech W7 to this soundbar ? Tjks
[ Scott m  Jan 29, 2022 ]
1 answer
The Studio 3D Mini uses HEOS for the wireless pairing of devices while the W7 uses DTS Play-Fi. These two devices will not be able to be synced as part of a wireless audio setup.
[ Davis  Feb 06, 2022 ]  Staff
Can you add HEOS enabled wireless rear surround speakers that work with the soundbar and sub-woofer for tv and movies, and not just music?
[ Jeff  Dec 26, 2021 ]
1 answer
Hi Jeff From what I understand you can add a pair of HEOS wireless speakers, but not to this soundbar. I believe that Denon has this setup available. Eventually I'm gonna upgrade to a true home theater setup. The DT Studio 3D Mini is absolutely phenomenal, but I went this because of my current budget. Hope this helps.
[ BRIAN  Dec 26, 2021 ]
For anyone who has purchased this soundbar, is the lack of center channel noticeable? I typically prefer a dedicated center channel and wondered how dialogue sounds using this soundbar.
[ Matt  Aug 27, 2021 ]
1 answer
Hi Matt, sticking with a dedicated center will give you the best overall sound option in general. If you need to downsize to a sound bar though, sticking with a model that includes good dialog enhancement like this Definitive Tech Studio 3D is your best bet.
[ Jenny  Sep 01, 2021 ]  Staff
