Loudspeaker for ceiling speakers (background sound) model PA-5060 with power 60 W for 100 V speakers and USB flash input and SD / MMC card input.
Professional surround sound amplifier with background or built-in 100V speakers with built-in Mp3 player with adjustable volume, jump or repeat track or 10 tracks. Microphone input with adjustable microphone 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.
