The tuner is a professional who is responsible for all the audio equipment on the stage. First of all, we need to concentrate all the sound sources on the mixer, divide them into sub-paths, group and adjust them, and then send the total output audio to the amplifier and speakers through the total sound equalization to make it with the venue. The acoustic characteristics are adapted. The tuner needs to know the music characteristics of each link, the frequency of the most easy feedback, and the resonance point of the venue to control the volume of each song and equalize them. In addition, it will be improved by the effector.
Vocals, instrumental sounds and familiarity with the functions and limitations of each piece of equipment, without distortion and other adverse effects. To ensure the quality and reliability of the selected equipment, it is necessary to prepare for the possible failures in advance and take effective remedies in time. Sometimes it is necessary to complete the preparation work a few hours before the performance. Although the time is very tight, in order to be safe, each signal line must be personally connected to be assured.
The average output power refers to the power that operates continuously for a long time. Peak power is the maximum power that can be tolerated in a short period of time. It is much larger than the rated power. The output of the amplified sound is determined by the power amplifier. A concert of a certain scale must have a certain power, and the standard is one watt per person. The power will vary depending on the type of concert, the size of the venue, the reverb and the number of speakers.
Mixer:
The main function of the mixer is to enlarge the multi-channel input signals, mixing, grouping, tone color correction and sound effect processing, audio transmission, program recording important equipment. In addition to the function, the mixer has easy operation and pure background. Static, putter smooth, smooth, wide frequency response, small distortion and so on. Total power / one power amplifier output power = number of required power amplifiers
Main function of 15-inch stage professional audio speaker

There are two evaluation criteria for professional 15-inch stage professional audio speakers. The first one is the objective standard, that is, the instrument testing standard; the second is the subjective evaluation standard. Among them, the instrument testing standard (that is, the objective standard) is clear, and the subjective standard is different from person to person. Therefore, firstly, it is necessary to detect good performance objectively, which is a good speaker and foundation. Of course, the subjective evaluation should be "resolving power". "High level of music analysis", "strong sense of vividness (music performance)", "good image (sound cohesion, positioning)", "airy (elasticity)", "high transparency" Good)).
