DTS Neo:X: What Is It and How Does It Work?

DTS-style surround sound expansion

DTS Neo:X is a 11.1 channel surround sound format. Similar to Dolby ProLogic IIz and Audyssey DSX surround sound processing formats, providing wide channel and height enhancement.

How does DTS Neo:X work?

Like ProLogic IIz and Audyssey DSX, DTS Neo:X does not require studios to mix soundtracks specifically for the 11.1-channel sound field. Still, it has DTS Neo:X capability and gives a more accurate result in doing so.

However, without optimizing the end of the mix, DTS Neo:X searches for tracks already present in stereo, 5.1 or 7.1 channel soundtracks. It provides a more immersive 3D listening environment by placing these signals in wide channels that are distributed at the front height and additional front and rear speakers.

DTS Neo:X channel and speaker settings

To experience the maximum benefit of DTS Neo:X processing, you must have a home theater receiver that provides an 11-speaker layout configuration. This means it supports 11-channel amplification and a subwoofer.

In the full 11.1 channel DTS Neo:X configuration, the speaker layout is as follows:

  • left front
  • Left front height
  • front center
  • right front
  • right front height
  • big left
  • big right
  • left fencing
  • Left wrap height
  • turn right
  • right cover height
  • Subwoofer (11.2 channel configuration uses two subwoofers)

An alternative speaker setup would remove the left and right surround speakers and instead place additional left and right speakers between the front left and right speakers and the large left and right speakers.

This variation of speaker placement widens the surround sound field, filling in the gaps between the surround and front speakers. It also adds a larger front soundstage with height channels placed above the front left and right speakers and additional sound from the rear via the surround back speakers. Sound from these speakers also reflects towards the listening position, giving the feel of sounds coming from above.

That’s too many speakers. While it is desirable to have a DTS Neo:X-capable home theater receiver that supports 11-channel internal amplification, you can also install it in a nine-channel internal amplification home theater receiver with preamp outputs for connectivity. . to external amplifiers that add the extra 10th and 11th channels needed.

DTS Neo:X is also scalable to operate in a 9.1 or 7.1 channel environment, and some home theater receivers include 7.1 or 9.1 channel options. In these configurations, the extra channels are doubled with the existing 9.1 or 7.1 channel layout. It may not be as effective as the desired 11.1 channel configuration. It still offers an expanded surround sound experience over the typical 5.1, 7.1 or 9.1 channel layout.

Additional Control Included in DTS Neo:X

For additional surround control, DTS Neo:X supports three listening modes:

  • Cinema: Gives extra attention to the center channel to avoid loss of dialogue in surround sound environment.
  • Music: Provides stability to the center channel while separating the channel from the rest of the soundtrack elements.
  • Matching: Provides more detailed sound placement and directionality, especially in width and height channels, to deliver a truly immersive surround sound experience.

DTS replaces Neo:X with DTS:X

DTS Neo:X should not be confused with DTS:X, an object-based surround sound encoding format introduced in 2015. It includes aerial audio immersion and is a standard surround sound option in most mid-range and high-end homes. standard cinema receivers. DTS:X can be considered an advanced version of Neo:X.

The addition of DTS:X for some home theater receivers eliminated the need for DTS Neo:X on future units. You probably won’t see Neo:X and DTS:X on the same receiver.

Some older home theater receivers equipped with DTS Neo:X support a DTS:X firmware update. In such cases, after installing the DTS:X firmware update, the DTS Neo:X feature will be modified and no longer accessible.

If you have a Neo:X receiver, a firmware update may be provided automatically. If unsure, check with technical or customer support for your particular make and model to see if it’s available.

If you have a home theater receiver that offers DTS Neo:X and cannot be upgraded to DTS:X, it will continue to work as designed. If you upgrade to a new home theater receiver, you will get DTS:X and DTS Neural Upmixer. DTS:X requires specially encoded content, but Neural Upmixer works similarly to DTS Neo:X in that it removes height and width cues from existing 2, 5.1 or 7.1 channel content, creating a similar immersive effect.

DTS Neo:X: What Is It and How Does It Work?

Surround sound expansion a la DTS

DTS Neo:X is an 11.1 channel surround sound format. It is similar to the Dolby ProLogic IIz and Audyssey DSX surround sound processing formats, which provide both height and wide channel enhancement.

How DTS Neo:X Works

Like the ProLogic IIz and Audyssey DSX, DTS Neo:X does not require studios to mix soundtracks specifically for the 11.1 channel sound field. Still, DTS Neo:X has the ability, and doing so delivers a more accurate result.

However, without optimizing the mixing end, DTS Neo:X looks for cues already present in stereo, 5.1, or 7.1 channel soundtracks. It places those cues within the front height and wide channels that are distributed to additional front height and rear height speakers, enabling a more enveloping 3D listening environment.

DTS Neo:X Channel and Speaker Configurations

To experience the maximum benefit of DTS Neo:X processing, you should have a home theater receiver that provides an 11 speaker layout configuration. That means it supports 11 channels of amplification and a subwoofer.

In a full 11.1 channel DTS Neo:X setup, the speaker arrangement is as follows:

Front left
Front left height
Front center
Front right
Front right height
Wide left
Wide right
Surround left
Surround left height
Surround right
Surround right height
Subwoofer (11.2 channel setup uses two subwoofers)

DTS
An alternate speaker setup would remove the surround left and right height speakers and instead incorporate additional left and right speakers between the left and right front and left and right wide speakers.

This speaker layout variation expands the surround sound field, filling the gaps between the surround and front speakers. It also adds a larger front soundstage with height channels placed above the front left and right front speakers and additional sound coming from the rear via back surround height speakers. The sound from these speakers also projects toward the listening position, giving the sensation of sounds coming from overhead.

That’s a lot of speakers. Although it is desirable to have a DTS Neo:X-enabled home theater receiver that supports 11 channels of built-in amplification, you can also incorporate it into a home theater receiver that has nine channels of built-in amplification with preamp outputs for connection to external amplifiers that add the needed extra 10th and 11th channels.

DTS Neo:X can also scale to work within a 9.1 or 7.1 channel environment, and some home theater receivers incorporate the 7.1 or 9.1 channel options. In these setups, the extra channels are folded with the existing 9.1 or 7.1 channel layout. It may not be as effective as the desired 11.1 channel setup. Still, it provides an expanded surround sound experience over the typical 5.1, 7.1, or 9.1 channel layout.

Additional Control Included With DTS Neo:X

For additional surround control, DTS Neo:X supports three listening modes:

Cinema: Provides extra emphasis to the center channel to avoid losing dialog in the surround sound environment.
Music: Provides stability to the center channel while providing channel separation of the rest of the elements in the soundtrack.
Game: Provides more detailed sound placement and directionality, especially in the wide and height channels, to provide a fully immersive surround sound experience.
DTS Replaces Neo:X With DTS:X

DTS Neo:X is not to be confused with DTS:X, which is an object-based surround sound encoding format introduced in 2015. It includes overhead sound immersion and is a standard surround sound option on most mid-range and high-end home theater receivers. DTS:X can be considered an evolved version of Neo:X.

For some home theater receivers, the addition of DTS:X has eliminated the need for DTS Neo:X on future units. You most likely won’t see both Neo:X and DTS:X included on the same receiver.

Some previous home theater receivers equipped with DTS Neo:X accept a DTS:X firmware update. In these cases, once the DTS:X firmware update is installed, the DTS Neo:X feature is overridden and no longer accessible.

If you have a receiver with Neo:X, a firmware update may be provided automatically. If you aren’t sure, check with customer or tech support for your specific brand and model to see if it is available.

If you own a home theater receiver that offers DTS Neo:X, and it is not upgradable to DTS:X, it will still work as designed. If you switch to a new home theater receiver, you will be provided with DTS:X and the DTS Neural Upmixer. DTS:X requires specifically encoded content, but the Neural Upmixer works in a similar fashion as DTS Neo:X because it creates a similar immersive effect by extracting height and wide cues with existing 2, 5.1, or 7.1 channel content.
