2U 5-zone independent volume control with Bluetooth constant voltage amplifier Public broadcast constant pressure power amplifier is one of the core equipments in the public broadcasting system, mainly used to drive the loudspeaker system, ampl the audio signal and transmit it to the loudspeakers in each area. Compared with constant resistance power amplifier, constant pressure power amplifier converts the audio signal into high voltage and low signal for transmission through transformer, which can reduce the line loss and is suitable for long-distance transmission and large-scale loudspeaker system.
2U 5-zone independent volume control with Bluetooth constant voltage amplifier Public broadcast constant pressure power amplifier with constant voltage power amplifier output, the voltage is usually fixed, common standard voltages are 70V,100V, etc. Audio signals are converted into high voltage, low current signals through transformers, and transmitted to various products. The product end is also equipped with a transformer, which converts the high voltage signal into a low voltage signal suitable for the speaker to work. Suitable for long-distance transmission and large-scale speaker systems. Constant power amplifiers can drive a large number of speakers, suitable for schools, shopping malls, factories, hospitals, airports and other places that need extensive coverage. High voltage transmission reduces loss, suitable for long-distance wiring. You can expand the coverage by increasing the number of speakers. With constant voltage output, the load change has little effect on the output voltage and the system has high stability. Public broadcast constant pressure power amplifier is used for public place broadcasting system, including schools, shopping malls, supermarkets, office buildings and other areas Play background music, broadcast and emergency notifications. Select the appropriate power amplifier according to the total power of the speaker. 50W-2000W is according to the demand You can also match the appropriate power amplifier according to the number of speakers provided by the customer and the power of the speakers.
2U 5-zone independent volume control with Bluetooth constant voltage amplifier Constant-voltage power amplifier function, radio, MP3 playback, Bluetooth connection, equalizer function, etc. Installation notes Use the audio cable to ensure stable signal transmission. Audio cables should be kept away from strong electrical cables to avoid signal interference. Speaker matching: Ensure that the transformer at speaker end matches the output voltage of the power amplifier. The total power of the speakers should not exceed the output power of the power amplifier. Installation location: The amplifier should be installed in a dry cabinet to avoid humidity and high temperatures. After installation, adjust the sound effects to ensure even distribution of sound. The volume should not be too, otherwise, it will distort. Public address constant-voltage power amplifiers are widely used in schools, shopping malls, hospitals, factories, etc., due to their transmission distance, easy expansion, and high stability. By choosing the power, output voltage, and functions reasonably and installing and adjusting them correctly, it is possible to ensure that the system runs stably and plays its best. If you need further information or want to purchase a constant-voltage power amplifier, you can contact us. We look forward to your cooperation.
