Digital Wireless PA System

 PA7500 wifi public address system includes a complete device for wireless PA solution, such as control host, wireless signal transmitter, wireless signal receiver, wireless PA amplifier, wireless PA speaker, etc. With wireless transmission, the system works in stable condition with wide broadcast coverage. The wireless public address system can do background broadcast, business broadcast, and emergency broadcast. It is an economic solution for large wireless public address projects such as village PA system, gas field PA system, railway station PA wireless public announcement system etc.

 

Intelligent PA System

 Since 1988, DSPPA has been developing its Public Address Systems continuously. Till now, DSPPA has launched the following series into the markets to meet different needs of projects:

 

There are many public announcement system manufacturers, but we are one of the best choices for you.

 

Power Amplifier

 There are 2 types of professional pa amplifier in DSPPA production line: analog power amplifier and digital power amplifier. The power amplifier has 2 types of speaker outputs: low current (resistance fixed) output at 4-16Ω) and high current (voltage fixed) output at 70V/100V.

 

DSPPA analog power amplifier use industrial circuit board and are simple and stable design for audio projects. They are equipped with 70V/100V speaker output and 4-16 ohms speaker output.

 

The 4-16 ohms speaker output ensures better sound effect while the 70V/100V speaker output ensures long distance transfer with best sound quality. They are ideal choice for Public Address Audio projects and Commercial Audio projects.
