The number of channels (e.g., 2.0, 2.1, 5.1) indicates the configuration of the sound system. The first digit refers to the speakers (e.g., front, rear), while the second to the subwoofers for bass. The more channels, the richer and more surround the sound is.

Connectivity describes the ways the device connects with other audio or video sources. It may include wired options such as HDMI, Optical input, AUX, as well as wireless options like Bluetooth and Wi-Fi, offering flexibility and ease of use.

Audio templates determine how sound is transmitted and reproduced. Advanced formats such as Dolby Atmos, DTS:X, and Dolby Digital offer multichannel sound and a realistic surround experience, ideal for movies, series, and gaming.
