Digital Audio
The principle of digital audio
Although there are various methods for converting analog signals into discrete digital signals, pulse code modulation (PCM) is commonly used in digital audio systems to convert continuous signals. PCM mode was invented by French A. H. Rivers in 1937 and has long been widely used in communication. With the advancement of semiconductor technology, especially in the stage of ultra large scale integrated circuits, PCM has been applied in the field of audio and has become a reality in households.

What is professional audio
Professional Audio Introduction to Professional Audio
A professional audio system consists of sound sources (music playback equipment, pickup equipment, i.e. microphones), control equipment (analog or digital mixing consoles), audio processors (previously using peripheral devices such as effectors, equalizers, limiters, dividers, signal distributors, and delay devices, but now there are also digital system controllers that integrate the above functions), power amplifiers (amplifiers), and speakers. The above devices are connected in series using various types of wires and cables.

How to choose a wireless microphone
Choosing a wireless microphone product that suits your needs and satisfies you after use, in addition to understanding the above reference principles, the real action is to collect more relevant information and conduct actual listening comparisons in order to buy a product that is worth the price. However, technological products are constantly evolving with new features. If you want to purchase a new product, you should choose the most advanced models available today. Even if the price is a bit expensive, there is no need to hesitate. Advanced products that are superior to others are worth your priority!

The difference between HiFi speakers and AV speakers
The sound effect created by the speaker is surround sound, and its front sound field has no depth, so it can be seen that the placement of the front speaker of the AV speaker is parallel to the display. The imaging power of this type of speaker is not as good as HiFi speakers because it can create grand scenes. To make up for this, a center speaker is added to highlight the sound field of the characters and compensate for the lack of intermediate imaging. In order to increase the sound field momentum, subwoofers are usually equipped, so the difference in sound field is the biggest difference between these two speakers.

Tips for using wireless microphones
Before choosing a wireless microphone, it is important to first understand the transmission frequency of the local TV station and avoid any mistakes when selecting. If conditions permit, high-density wire mesh or iron sheet should be added at the top and around the building during construction to shield and isolate external wireless signal interference. Alternatively, the SQUEICH knob on the receiver can be used to suppress the interference signal (but this has an impact on the receiving distance of the microphone).

Four elements of power amplifier and speaker matching
From a technical perspective, the elements for matching power amplifiers with speakers include: 1. power matching, 2. power reserve matching, 3. impedance matching, and 4. damping coefficient matching. If we recognize the above four points when matching, we can fully and maximally utilize the performance of the equipment used.
