If you have a receiver or are looking for it, you have probably seen that there are quite a few different surround formats . But what are all these surround formats for and are they useful in your home cinema system? Earlier we looked at the Dolby ProLogic formats and the DTS-HD and Dolby TrueHD formats, this time we look at the somewhat unknown DTS Neo: X.
DTS Neo: X
DTS Neo: X is a format or standard comparable to Dolby ProLogic IIz and Audyssey DSX . With this format it is possible to control an 11.1-channel home cinema system with 11 speakers and a subwoofer. That is of course a lot of speakers and therefore a format that will be used little or never for most home cinema systems.
This format can be used in two ways. Firstly, source material recorded with an 11.1-channel audio track can be reproduced exactly like this, but it is also possible to generate an 11.1-channel signal from a source with a 5.1-channel or 7.1-channel audio track. For this second option, use is made of the existing signal that is distributed over several channels by software. These extra channels are often speakers that are used in width or height and therefore have to provide a so-called ‘3D’ surround experience. In such a configuration, the height ‘height’ speakers provide the effects and background music. The wide ‘width’ speakers expand the front portion of the audio and enhance the front-side action.
The DTS Neo: X format is used in more and more receivers , but in order to support the format, these receivers must have the ability to control 11 channels. It is also possible that a receiver with DTS Neo: X has a 9-channel amplifier with pre-amp outputs to which an external receiver / amplifier can be connected that controls the additional channels. It should also be said that although DTS Neo: X is designed for an 11.1-channel home cinema system, it can also be adapted for a 9.1 or 9.2-channel configuration. However, this depends on the receiver.
