7.1 sound cards

7.1

— this multi-channel surround sound format can be called an extension of the popular 5.1: five main channels (centre, two front and two rear) are supplemented by two more. There are several versions of 7.1 that differ precisely in the location of additional channels, but they all have common features: on the one hand, they provide more accurate surround sound transmission than 5.1, on the other hand, they require more complex speaker systems and are also poorly compatible with headphones.
