The function of the main speaker has a great impact on the playback quality of the entire audio system, and the full-range speaker and subwoofer can also be selected for combined playback, so that the combination of the two is the role of the main speaker.

The monitor speaker is used in the control room and recording studio for program monitoring, it has the characteristics of small distortion, wide and straight frequency response, and little modification of the signal, so it can most truly reproduce the original appearance of the program, and has a strong authenticity. Monitors, also known as stage monitors, are generally used on stages or dance halls for actors or band members to monitor their singing or playing sounds. Generally, the listening speaker is made into an inclined shape and placed on the ground, so that it can not only be placed on the stage without affecting the overall shape of the stage, but also can be heard clearly by the people on the stage when playing the sound, and will not cause the sound to be fed back to the microphone and cause whistling sound, so that the whole event site is polluted by noise.

It is necessary to choose the purchase of a combined sound style according to the environment of the room in which I accompany the morning, and the desktop audio has a small volume and power, which is more suitable for a room with a small environment; The floor-standing combination speaker has a large volume and power, which is more suitable for use in large rooms.

2. The products sold by the combined audio Hongshi are marked with the "CCC" mark, indicating that the product performance and electromagnetic compatibility performance meet the requirements of the national mandatory specifications, and the products without the "CCC" mark are likely to be at risk in the process of use, and consumers must not buy them.

3. See whether there are burrs in the appearance of the audio, whether the brightness and divergence are good, whether the box lines are fluent and clear, and then check whether the accessories of the whole machine can be complete according to the clarification book; And check whether the function buttons can be operated easily.

1. What are the methods of audio maintenance?

1.Potentiometers, in fact, this kind of problem can be judged to be a problem with the phaser that adjusts the volume. Most loudspeakers use potentiometers to change the strength of the signal (except for digital tuning potentiometers) to adjust the volume and bass.

The potentiometer changes the position of the carbon resistor through a movable contact, thereby changing the resistance value. With the increase of use time, dust or impurities will fall into the potentiometer, and the contacts of the potentiometer may also oxidize and rust, resulting in unreal contact, and there will be a "crackling" noise when adjusting the volume. (This article is provided by Wuhan Yima Shed Qianju Smart Home Friendly), solution:

Replacing the potentiometer costs only about 2 yuan, but you have to do it yourself. In addition, the four crimp lugs behind the potentiometer can be opened to expose the movable contacts of the potentiometer. Then, clean the carbon barrier with anhydrous alcohol, and then drop a drop of oil on the carbon barrier, and then install it to solve the noise problem.

Second, what are the purchase skills of audio?

1.For the understanding of the speaker, it can be identified by the steps of "viewing, checking, knocking, and recognizing": that is, one view of the process, two weights, three knocks on the box, and four recognition of the nameplate.

3.The ability to balance natural tones: A good speaker should reproduce the original characteristics and attributes of the sound and instrument in a complete and realistic way.

The sound should sound smooth and unpolished, with no noticeable treble distortion, and no oppressive or empty feeling of midrange and treble.

4.The sound effect of the speaker is very important,We can adjust the volume of the speaker to the maximum,Listen to whether it has noise at a distance of about an inch from the speaker,Judge its sound quality clearly and smoothly by listening**,In this process,We can adjust the volume,The sound quality of the speaker will not change because of the change in volume,When we turn off the speaker,If it makes a large impact sound,It means that the quality of its speaker is not good。
