How to choose KTV audio equipment.Ningbo bar professional audio

　　At the top of the list, pay attention to whether the speaker cabinet has resonance. Generally speaking, a speaker with a thin cabinet or a plastic enclosure will resonate when outputting a large volume in the low frequency range below 200 Hz. The presence of cabinet resonance will seriously affect the output sound quality, so users should try their best to choose speakers with wooden enclosures when choosing speakers.

　　Second, pay attention to whether the case is anti-magnetic. Since the display is very sensitive to the surrounding magnetic field, if the magnetic field of the KTV audio cabinet is large, the pictures on the screen will be affected, and even the life of the display will be reduced, so you must pay special attention when choosing.

　　Third, pay attention to the airtightness of the speaker cabinet. Because the better the airtightness of the speaker, the better the output sound quality. The airtightness check method is very simple. The user can put his hand outside the inverted hole of the speaker. If there is obvious air rushing out or sucking in, it indicates that the airtight function of the speaker is good.

　　Fourth, pay attention to whether the tone output from the KTV audio cabinet is uniform. Since the sound source of multimedia music is mainly games and general music, the high-pitched voice accounted for a larger share, and the low-pitched voice accounted for a smaller share.

　　Fifth, we must pay attention to the positioning ability of the sound field. The ability of speaker positioning is directly related to the on-the-spot role of users in playing games and watching movies.

　　Sixth, attention should be paid to the dynamic expansion limit of KTV audio speakers in the frequency domain. That is, when the user increases the volume of the speaker and exceeds a certain limit, whether the speaker can still maintain a uniform and clear sound source signal amplification capability in the full range.
