Custom Amp(customized 1.5U power amplifier)

Layvikay provides high-performance custom amp (public address power amplifier) at competitive prices. Differing from the professional audio 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.

Features:

  • Constant Voltage + Constant Resistance Dual Functions
  • MIC1+MIC2 Dual Microphone System
  • 2 Zones Independent Control
  • Digital Display
  • SD Card/USB Audio Input
  • Power and Clip LED Indicator
  • Short Circuit Protection
  • Overheat Protection
  • Soft Start Protection
  • Input and Output Overload Protection
