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.
