How is sound produced? What is the speed of sound?
The Ims time difference in the sound system is also to be taken seriously, because a difference of lms brings about a distance difference of 34cm. For example, some sound engineers place pickup microphones inside and outside the bottom drum when picking up the bottom drum, the distance between the two microphones is about 34cm, and then give a 1ms delay to the microphone inside the bottom drum at the digital mixing console, which is to consider the speed of sound and the time difference.

What is the lighting DMX512 protocol?
The DMX512 protocol is a data dimming protocol proposed by the United States Stage Lighting Institute (USITT), which gives a protocol standard for communication between lighting controllers and luminaire equipment, as it was proposed in 1990, so the full name of the protocol is USITTDMX512 (1990). The proposed protocol provides a good standard for the use of digital signals to control lighting equipment.

RS-232 standard interface (also known as EIARS-232) is one of the commonly used serial communication interface standards, it is by the American Electronic Industry Association (ElectronicIndustryAssociation, EIA) in conjunction with Bell Systems, modem manufacturers and computer terminal manufacturers in 1970 jointly developed, its full name is "data terminal equipment (DTE) and data communications equipment (DCE) between the serial binary data exchange interface technology standards".

Smart meters were developed with the maturity of microcontroller technology in the early 80s, and the world meter market was basically monopolised by smart meters, which was attributed to the need for enterprise informatization, and one of the necessary conditions for enterprises in the selection of meters was to have a networked communication interface. Initially it was the data analogue signal output simple process quantity, later the instrument interface was RS232 interface, this interface can realize the point to point communication way, but this way can not realize the networking function, then appeared the RS485 solved this problem.

Digital IP network broadcasting is a purely digital one-way, two-way and multi-way audio reinforcement system based on IP data network, which transmits audio signals in packet form according to TCP\IP protocol on LAN or WAN, and then decoded by the terminal.

Layered lighting is a common way of lighting a studio. This lighting method can enhance the subject and the sense of perspective. The illumination of these three areas is different, the illumination of the front area should be in 2000-2500lx, the illumination of the middle area should be in 1500-2000lx, the illumination of the back area should be in 800-1000lx, the illumination of the canopy light should be in 600-800lx. The purpose of zoning lighting is to give a sense of hierarchy and three-dimensionality.

XLR connectors are the most widely used type of connector in professional audio systems and can be used to transmit various types of audio signals in audio systems. Generally balanced input and output terminals are connected using XLR connectors. In a sense, the use of XLR connectors is also one of the features that distinguish professional audio systems from residential audio, the benefits of which are.
