Multi-channel power amplifier can also be used to play stereo music?

              Multi-channel power amplifier can also be used to play stereo music?

Many people build a home theater system and often like to buy a larger floor-standing speaker as the main channel. In addition to making a more complete connection with the most important center channel in the theater system, it can also be used as a pure speaker. Listen in two channels. Why is there a need for "pure two-channel" listening? For a long time, the correctness of listening to music in multi-channel has been criticized by audio players. The reason is that most music software uses two-channel recording. Of course, it should be presented in two-channel system to have the most accurate Excellent sound imaging and sound field effects.

If the two-channel music is decoded by the surround amplifier and then sounded through the multi-channel speakers, it may cause image confusion, and there will also be phase differences when the sound is sounded through speakers with inconsistent structures, and the final music presented The effect is far from what was intended when the music was recorded. It is a pity that even if theater players buy a set of excellent multi-channel speakers, they usually only use the main channel speakers to listen to music.

However, in the past, I also thought that "multi-channel + surround playback" should be used for watching movies, and "two-channel + plus front and rear amplifiers" should be used for listening to music. This idea has long been ingrained in my mind. It was only after the editor-in-chief of this magazine introduced me to music software specially recorded for multi-channel systems this month that I completely overturned this thinking. It turns out that using multi-channel to listen to music is not only as effective as two-channel, but it is even easier to create a natural sound field effect than two-channel. The key is to choose the "correct software".

During the listening process, first play the live concert software of trumpet player Chris Botti. Regardless of the multi-channel sound quality, this music software has undergone professional multi-channel recording, and the ambient sound and reflection sound in the space are passed through the speaker at this position. It occurs directly, which can create a quite natural stereo sound field and spatial reverberation. The subtle details of the hall sound in the air are very realistic. It is as real as if you are in the auditorium of the performance site, and it is more immersive than the previous two-channel front sound field.

The next thing to play is the Enrique Iglesias-Bailando MV clip in the Dolby Atoms test film. In addition to the position of the human voice constantly moving with the video, many complex sound effects are added in the space, which not only makes the listener more Immersively integrated into the MV scene, it is also easier to convey the performer's creative ideas. With such recording software, the creation of musicians no longer only has a flat effect, but also can add many unconstrained ideas to create more possibilities for music!

Having said that, it is still quite difficult to produce multi-channel music. First of all, the recording technology is relatively difficult and the cost is high. There are few groups of people listening to multi-channel music software on the market, so it is not economical. . And looking at the currently highest-standard Dolby Atmos and DTS:X formats, the audio source signal can only support lossless sound quality, which is still a long way from the high-resolution files of two-channel music software, or even pure analog. All in all, there is absolutely no doubt about the effect of listening to music with multi-channel. With the rise of home theater, it is very worthwhile to compare whether more musicians will invest in multi-channel music creation in the future, or whether theater software will release higher specifications. expected!
