PA System Amplifier
Layvikay provides high-performance PA system amplifier (public address power amplifier) at competitive prices. Differing from the professional power amplifier, the PA amplifier has two types of speaker outputs: one is the constant resistance with 4-16Ω, and the other is the constant voltage with 70V/100V.
Besides its regular functions, it has independent zone control, with microphone inputs in 6.35mm/XLR/combo sockets, auxiliary line inputs in RCA/combo sockets, MP3/SD card/USB, an AM/FM tuner, a built-in Chime, and more. Additionally, it has built-in protection circuits, with overload, output DC, and power-on delay protection functions.
Without a doubt, they are your perfect choice for public broadcasting/ background music in shops, offices, schools, warehouses, churches, restaurants and other public areas.

- 6 Zones Independent Control
- Digital Display
- SD Card/USB Audio Input
- Power and Clip LED Indicator
