Active speakers change the way you listen
Nowadays, the ways of listening to music are becoming more and more diversified. It is no longer the era of only CD records, vinyl records or radio. There are countless tools for accessing music in daily life, such as portable devices such as mobile phones or tablets, PCs that everyone has, music channels in digital TV set-top boxes, and even a Blu-ray player connected to the Internet to listen to endless streams of music. It seemed unimaginable in the past. Compared with the source of music, has the current audio equipment become more convenient to use? certainly! The active speaker to be introduced next allows you to listen to music by connecting the speaker directly to the player without the need for a power amplifier. The audio system at home is simpler and the wires are simpler.
2. Digital input
In addition to no longer needing an amplifier driver for active speakers, some active speakers even have a built-in DAC, allowing users to directly input digital audio signals, even saving analog audio signals, and digital signals are not limited by the transmission distance. It is no problem if the player is far away from the speaker.
3. Mini 2.1 channel
The general 2.1-channel system is to add an active subwoofer to the original 2-channel speakers to increase the sense of low-frequency volume and extension. Only when the frequency point is used can the subwoofer produce extra points, but today's mini 2.1-channel system comes from different thinking. It is a holistic consideration from the very beginning, not only the frequency crossover point has been tailored, but the driving force of the two-channel small speaker is also from the subwoofer, so it can be listened to by directly inputting the signal, without an amplifier at all. The advantage of this system is that the two-channel speakers are small in size and very easy to place, and the subwoofer can complement the mid-low frequency band, so that the listener can get a very abundant sense of energy and sufficient bandwidth, and they all have a remote control. It is very convenient to adjust the volume or switch the signal source.
4. Desktop listening
Desktop listening has become more and more popular in recent years. The main reason is that more people use PCs as personal entertainment centers, such as listening to music, watching movies, playing games, etc., are all done through PCs. It is inevitable that some people will demand better listening effects, so the demand for desktop listening has arisen as the times require. Since the desktop is the place to listen, naturally there will not be much space for amplifiers. At this time, active speakers are the best choice, but the speakers for the desktop must be small enough, and the speaker structure must be strong enough. In addition to the small space, the vibration of small speakers is also small, which is less likely to cause resonance on the desktop, and the sound will be cleaner.
5. Wireless input
The step-by-step development of active speakers is to make users more convenient to use and listen to music more freely. Digital input is very convenient, but you still need to connect the signal cable. Now that you have wireless speakers, you don’t need to connect cables. You can really place the speakers anywhere, as long as they are powered on. This kind of product must have a transmitter, and the transmitter can accept different types of interfaces, such as USB and S/PDIF, so that it can be directly connected to PC and CD player.
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。
The basic composition of the listening system and the selection of amplifiers and speakersBasic components of a listening systemFirst, let’s talk about the composition of a complete system. Simply put, it can basically consist of the following three parts:Audio source, amplifier, speakers.Sound sour
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
