Audio format

The audio format produced by a sound projector is actually the largest number of individual audio channels supported by the device. Note that in this case we are talking about the number of real channels, that is, channels for each of which at least one speaker is allocated; Models that support virtual surround sound can give the listener the impression of more channels than there actually are (see below for more details).

The sound format is indicated by two or three numbers separated by a dot. The first indicates the number of main channels, the second - the number of subwoofers, the third - the number of additional vertical radiators. For example, 2.1 format corresponds to stereo sound (2.0) supplemented by a subwoofer. And the conditional 3.1.2 format includes left, right and center channels, a subwoofer, left and right vertical speakers.

Sound projectors that support a more advanced sound format than 3.1 are designated in our catalog as multi-channel. The classic multichannel audio format is 5.1, but there are other options. In any case, a large number of real channels contributes to the fidelity of the reproduced sound and simplifies setup compared to virtual surround sound systems, but is also more expensive.

The most common sound formats are: 2.0, 2.1, 3.0, 3.1, 4.1, 5.1, 5.1.2, 7.1.

Rated power

The total power rating of the sound projector speakers (including subwoofer, if present).

This parameter is often used to estimate the overall sound volume of the device, but this is not entirely true. The fact is that the actual sound volume is determined mainly by the power of the main speakers of the sound projector, and the total power is the sum of this power and the power of the subwoofer. Therefore, models with the same power rating can vary markedly in actual volume: for example, a 150-watt soundbar with a 50-watt subwoofer will be louder than a 100-watt projector with a subwoofer of the same power, although in both cases the rated power will be equal to 200 watts.

Summing up, we can say that it is possible to evaluate the volume by rated power only if the sound projector is not equipped with a subwoofer — in such models, the rated power is equal to the power of the main speakers. In other cases, it is worth focus on the power of the soundbar and the power of the subwoofer directly stated in the characteristics (see below for both).
