Subwoofer (RMS)

Rated power of the subwoofer supplied with the home theater. See "Front" above for details on power rating; here we note that subwoofers often have a fairly high power, because. they are designed to cover low frequencies in all audio channels.

Frequency range

The range of audio frequencies reproduced by a home theater speaker system. The wider the range — the richer the sound, the less likely it is that the acoustics will “cut off” part of the low or high frequencies. When evaluating this indicator, one should proceed from the fact that the range perceived by the average human ear is from 16 Hz to 20 kHz. However, modern home cinemas for the most part cover this range completely or almost completely.

Number of channels

The number of amplifier channels may be greater than the total number of speakers in the system. This allows you to equip your home theater with new speakers and expand the sound quality of the system as a whole. More specifically, you can read about the appointment of the number of channels in the “Acoustics” paragraph. And this item is especially relevant for 5.1 systems, in which the receiver is equipped with a 7.1 amplifier thanks to it.

Front

Rated power delivered by the built-in home theater power amplifier per front channel.

Note that in home theaters the rated power of the amplifier output to any channel (any channel, not just the front one) is usually equal to the rated power of the standard speaker installed on this channel (see above). Therefore, many manufacturers do not give the characteristics of the built-in amplifier separately at all — firstly, they are easy to determine from the information about the speakers, and secondly, when using a system with complete acoustics, these data are not required. However, information about the power of the amplifier is indispensable if you plan to use third-party speakers instead of standard acoustics. The rated power of each such speaker must not be lower than the rated power on the corresponding amplifier channel — otherwise, various undesirable phenomena are possible at high volume, from sound distortion to damage to the speaker.

Rear

Rated power delivered by the built-in home theater power amplifier per rear channel. For more information about this characteristic, see "Front" above.

Centre

Rated power delivered by the built-in home theater power amplifier per centre channel. For more information about this characteristic, see "Front" above.

Amplifier frequency range

The range of audio frequencies that the built-in home theater amplifier can produce. This indicator is similar to the speaker range described above: the wider it is, the more part of the sound is covered by the device, the less high and low frequencies are outside the operating range. At the same time, it is worth noting that the frequency range of the amplifier, usually, corresponds to the capabilities of the complete speakers. Therefore, usually, you have to pay attention to this parameter only when connecting "non-native" acoustics: it is desirable that its range is not narrower than that of the amplifier, otherwise the latter will not be able to realize all its capabilities.

Multi Zone

Multi Zone makes it possible to use a home theater receiver to simultaneously transmit signals from different sources to screens and speakers located in different places (zones). For example, in a large house, you can simultaneously stream a movie to a screen in a large room, a TV show to a TV in the kitchen, and a radio programme to speakers in a library.

Progressive scan

Home theater support for progressive scan, namely, the ability to output a video signal with such a scan.

Initially, scanning was called a method of constructing an image on the screen of a kinescope TV. In such screens, an electron beam is responsible for the image, running around the screen and drawing each frame line by line. Different types of scanning differ in the order of these lines: with the interlaced method, the beam first draws odd lines (1, 3, ...), then even ones (2, 4, ...), and with progressive — each line in turn. The second option is considered more advanced, because. improves image quality and reduces the chance of noise and artifacts. Liquid crystal displays use other imaging methods; nevertheless, the visible features of both types of sweep are preserved for them.

Note that progressive scan is only available if progressive scan is supported not only by the home theater system, but also by the screen on which the images are displayed. On the other hand, most modern TVs meet these requirements; therefore, although it would not hurt to clarify compatibility, most likely there will be no problems with it.
