RH-AUDIO

  Many people misunderstand it as a stereo system because there are two channels, and the stereo mixer is connected to the system before the stereo amplifier and equalizer are used in the whole system. However, what these systems lack is the uniform coverage of the whole auditory area, as well as the minimal difference in sound pressure level and phase response of each channel to the coverage of the auditory area. If the  two channel 100V amplifie  system plays stereo signals without providing smooth overlapping coverage, half of the people in the listening area can only hear half of the audio content, which makes the dual-channel system a bad choice for music amplification. Most listeners hear a completely different mix of music from others. This is too common an oversight in venues for music and entertainment purposes, even in high-quality venues that should have better system design. It is a common misunderstanding for people with working background of tour or live aud...

  The directivity of  best column speakers  decreases with the decrease of frequency. That is to say, the directivity at low frequencies is very poor. Therefore, the vertical directivity of the sound column should be improved, even if the directivity at high frequency is weakened, while the directivity at low frequency is increased. Usually, the sound column can be divided into high and low frequency bands, followed by a frequency division network, so that the long sound column can produce low frequency sound, while the short sound column can produce high frequency sound to improve its frequency response. Or some important venues commonly used methods, in the frequency band above 1KHz with a high-frequency loudspeaker separated to sound, to improve high-frequency directivity and high-frequency band timbre. Based on the principle of acoustic filter, a layer of sound-absorbing material (such as ultra-fine glass wool) with gradually varying thickness is coated on the best co...

  Because the main function of  horn speaker  is to express the delicate sound, the installation position of loudspeaker is very particular. If the installation position is not scientific, the sound field effect will be unsatisfactory. The loudspeaker should be installed as far as possible in the same position as the human ear, such as on the A-pillar of the car, or above the dashboard, and on the door of the car, so that the sound field is basically equal to that of the human ear, and the car owner can appreciate the charm of the music. Horn speakers are used in vehicle, factory, school, station, wharf, shopping mall, shop and other places as power recovery equipment for background music, fire fighting, paging, campus broadcasting. It can also be used in police cars, fire engines, ambulances, patrol motorcycles, security booths, etc., as fire fighting, security, rescue, propaganda, shouting equipment. Good bass effect and life recognition are good choices for broadcastin...
