PA-100UB background PA amplifier (ceiling speakers) with 100 W power for 100 V speakers and USB, SD, FM radio.
Professional surround sound amplifier with 100V built-in or built-in speakers with built-in Mp3 player with adjustable volume, jump or repeat track. Two microphone inputs with adjustable volume. Separate volume controllers on both lines. High and low frequency controllers. Light level indication for output power. When the red indicator light is on, you need to decrease the volume.
Before turning on the "Power" button, all potentiometers must be reset (the rotary knobs are in the lowest position) because if any button is at maximum you can burn the amplifier or damage the speakers, this failure is not covered by The warranty. If you want to increase the volume by increasing the speaker power, please use a larger cross-section of the cable connection. If the amplifier works for a long time in overload mode (if the amplifier power does not match the power of the amplifier) it will be damaged and this failure is not covered by the warranty.
