AV Receiver listening modes & Surround formats explained

Av receiver listening modes

Modern Audio/Video receiver listening mode can be confusing and it can be hard to choose the right one for your home theater. These modes are not only found in AV receivers but also in preamps and integrated amplifiers.

It is important to know which mode to choose for your setup for the best experience, something that is going to help you do by explaining the different modes.

AV receiver/preamp/integrated amplifier listening modes include;

  • THX Cinema
  • DTS-MAHD
  • Stereo
  • PlIIz
  • DTS Neo-X Music/DTS Neural:X
  • Dolby Atmos
  • DSD
  • Dolby Digital and Dolby Digital plus
  • Direct mode and Pure direct
  • Dolby True HD

These are just some of the examples but the list is huge. Before we go into the details of each listening mode, there are several things that you should know.

What is a receiver listening mode?

A receiver listening mode is preset on your audio/visual processor that tells it how it should play the audio signals that come from your sources. Choosing the right listening mode can transform the listening experience in your dedicated home theater or media room with stunning sound and high fidelity.

For example, if you are watching an adventure movie, you may want to use one of the surround modes such as Dolby Atmos for an immersive, directional, and object-based sound format.

Depending on the audio that is being played and how you want to hear it, you can choose one of the listening modes. However, they are not always named as listening modes in all audio processing devices. Other terms that can be used to refer to this are;

  • Sound mode
  • Decoding mode
  • Sound field
  • Sound program

These modes can also be broken down into compressed or uncompressed modes and by this, I do not mean the audio quality. Compressed sound modes are digital modes that we are used these days like DTS-X or Dolby Digital while uncompressed sound modes are the more traditional/analog modes that are mainly transported through RCA cables.

This brings me to the next point that can best help you understand the different listening modes.

Audio encoding and audio decoding

Remember how I told you about uncompressed and compressed sound modes. The thing is, you can play uncompressed directly from your source to your speakers but it is a different case for compressed sound modes.

Compressed sound modes are sound modes that have been transformed from uncompressed formats (analog) to a compressed formats (digital). This is what is known as audio encoding. A good example of an uncompressed sound is your voice.

Audio decoding, on the other hand, is where the compressed sound mode is unpacked in an audio processor such as a receiver and sent to the speakers in a form that you can hear. So, if your audio processor does not decode a certain encoded sound mode, you will not be able to hear it.

There are three main listening mode categories that you need to know about;

  • Direct
  • Licensed
  • Proprietary

Direct

Stereo

Sends sound to the front right and left channels plus the LFE channel.

You can use this sound mode when you are watching older CD movies, songs, and shows that were recorded with 2 channels.

When you play a multichannel soundtrack or movie with this mode the audio signals are combined into the 2 front channels and subwoofer with no additional sound processing.

Mono

This listening mode sends the same signal to both the front right and left channels.

Suitable for watching older movies and soundtracks that were recorded in monophonic (mono) sound production.

Full mono

Outputs the same audio to every speaker regardless of the position or channel.

Multichannel (Multi ch)

Passes the unchanged (uncompressed) sound to the speakers. Great for playing audio from multi-channel PCM (Pulse-code Modulation) sources.

Direct

This mode plays the audio as it was recorded without processing and can be used for both digital and analog sound.

For example, if you play a 2-channel soundtrack, only the 2 front channels will play the audio regardless of the number of speakers you have.

Pure audio (Pure Direct)

Pure direct is the same as direct but in this case, the video (DSP) processing is turned off for a better high fidelity by lowering the noise.

All channel stereo (party mode)

All channel stereo mode takes the stereo audio (front left and right) and puts/clones it to the surround and back speakers.

Not great for critical listening as you lose the front sound stage appearance but is great for parties.

Licensed

Dolby Pro Logic II (PLII)

Dolby Pro Logic II creates a 5.1 channel from stereo signals (2 channels) by using hidden audio cues in the 2-channel signals. This mode is mainly used for watching stereo-only non-HD TV channels.

Pro Logic IIx (PLIIx) expands a 2-channel or 5.1 channel audio signal for a 6.1 or 7.1 channel playback providing support for additional speakers and a seamless surround sound.

Pro Logic IIz (PlIIz) expands 5.1 or 7.1 channel audio signals to a 9.1 channel or 7.1 channel with an additional of 2 front height channels. By doing this, the PLIIz mode adds more depth to the sound in your home theater.

Dolby Digital (Dolby D, DD, or AC-3)

Dolby D is made up of 6 discrete channels, 5 for the speakers, and one for the LFE channel (subwoofer).

Dolby Digital plus (Dolby D+ or E-AC-3) is an enhanced 5.1 channel Dolby Digital-based sound mode adding more channels (up to 15.1) and improving the surround sound with little compression. This mode can be used when streaming from your phone, tablet, computer, or when you are playing some Blu-rays.

Dolby TrueHD is a lossless sound mode that is great when you are playing Blu-ray movies for high-fidelity audio. And like the Dolby Digital+ mode, Dolby TrueHD can also support up to 16 channels.

Dolby Atmos

Dolby Atmos is a precise object-based surround sound mode that creates the illusion of sound moving around you. This listening mode can be used for a 5.1 or 7.1-channel setup and also takes advantage of height speakers when playing movies that incorporate Dolby Atmos audio.

DTS (Digital Theater Systems)

DTS is a surround mode that is ideal for playing movies/soundtracks recorded in DTS. This mode can be used for up to 6 discrete channels (5.1 channels) for high-fidelity sound.

DTS 96/24 sound mode is great for playing audio from 96/24 (96 kHz sampling rate + 24-bit resolution) sources.

DTS-HD HR (Digital-HD High resolution) mode can deliver audio for up to 7.1 channels at a 94 kHz sampling from Blu-ray or HD DVD sources.

DTS-HD MSTR (DTS-HD Master or DTS++) sound mode can deliver sound at a sampling rate of 192 kHz and 24-bit for an unlimited number of channels. Similar to DTS-HD HR, DTS++ can be used for HD DVD and Blu-ray soundtracks.

DTS Express can be used to play audio from DTS express sources.

DTS Neo:6

DTS Neo:6 is a post-processing surround sound mode that enhances a 2-channel audio signal in a home theater. It does this by analyzing sonic cues in the 2-channel signals and distributes the sound into 6 channels on Blu-rays and DVDs.

DTS X

DTS X is an alternative to the Digital Atmos sound mode as it is also an object-based surround sound mode. This mode also creates an immersive, multi-dimensional, and lifelike sound from DTS X Blu-rays, DVDs, and online movies.

DTS Neural:X

DTS Neural:X is an upmixing surround sound format that creates an imitation of the DTS X listening mode for up to a 5.1 channel set up with height speakers.

DTS-ES (DTS Extended Surround)

DTS Extended surround sound mode allows for the addition of an extra channel to a 5.1 channel surround sound setup. This mode can come in either DTS-ES 6.1 Discrete or DTS ES-Matrix.

DTS ES 6.1 discrete is used to play DTS-ES soundtracks in a setup that has extra rear channels for a 6.1 or 7.1 playback.

DTS ES Matrix is used to play DTS-ES soundtracks providing a matrixed center-surround channel and 5.1 discrete channels.

Auro-3D

These sound formats allow for the addition of height speakers in a 5.1 speaker setup and can be found in newer Marantz and Denon receivers. However, if you have older models, you can do a paid upgrade to have this format as an option.

Proprietary Modes

These are legacy formats from a manufacturer trying to show that they have more features than other receiver manufacturers. I would not highly recommend using these sound modes.
