Release the sound from the channel - Dolby Atmos concept
By introducing two concepts to cinema sound, Dolby Atmos creates breathtaking, flowing sound: audio objects and overhead speakers. By combining the two, you can completely revolutionize the way tracks are made and heard.
Traditional surround soundtracks limit all effects to a few channels, so they can only sound from a few perceptual angles. This type of surround sound can't apply effects above your head. In addition, sound effects exist only as part of the channel mix. If one effect is enhanced in a traditional mix, other effects are suppressed.
By contrast, Dolby Atmos frees the sound from the channel. This technique allows artists to treat specific sound effects as separate entities (called "audio objects"). Soundtrack creators can precisely deploy and move such objects anywhere in the theater's 3D space without restricting them to a specific channel; of course, artists can continue to use the original channel functionality as needed. The Dolby Atmos cinema processor then chooses which of the various front, rear, side and overhead speakers in the theater to use to reproduce this lifelike motion.
As a result, the Dolby Atmos soundtrack brings the on-screen action to the audience in a way never before possible. The movie's sound effects will surround you and fully immerse you in the storyline, enhancing the story and creating an action-packed cinema experience.
What is stereo audio? What is the difference between mono and surround sound?Stereo audio has been the dominant format for analog or digital audio in the music industry for decades. It's a relatively simple format that does a good job of simulating the way we naturally hear the world around us, and
合并式胆机还需要再加一个前级吗?很多烧友都有这样的疑问。这里有三个因素,一是音源输出的讯号是否大?很多外国CD机输出讯号偏小,加台前级可以放大讯号。二是音箱的灵敏度,灵敏度在90dB以下的音箱,加台前级,声音的表现会更好。三是胆机的放大量,增益30dB的标准合并式胆机,对输入讯号的放大量约15倍左右。而增益为20dB的合并式胆机,放大量约10倍,略显不足,动态会有欠缺。如果你对声音有很高的要求,最好再添一台前级做配套,将合并功放作为后级用。前级可以增10倍放大量,两台机加起来增益可达40dB。这时候,后级会推得更轻松、声音密度高、细节丰富、瞬态更强,音响系统的表现就非常完美了。

What is an AV amplifierThe A (audio) of the AV amplifier represents audio and sound, and the V (video) represents audio and image. Therefore, the AV amplifier is an audio-visual amplifier that combines audio and video signal processing. It emphasizes the atmo
About--Basic knowledge of power amplifiersThe working principle of the power amplifier is actually very simple. Intuitively, it amplifies various sound signals played by the audio source to push the speaker to produce sound. From a technical point of view, a power amplifier is like a current modulat
