MP260U/MP212U is advanced public address equipment integrating MP3 player, FM tuner, zone manager (6 zones), preamplifier and post power amplifier.
This equipment has three line signal input interfaces, one line signal output interface, and two routes of the microphone input interfaces, of which the signal from the interface of microphone 1# on the front panel shall be granted the highest priority level. Each sound source input (including the MP3 player and FM tuner built in this equipment) shall be provided with the independent volume adjustment button, and the preamplifier shall be provided with the treble and bass adjustment knob. The six zones are subject to the output at the constant voltage of 100V. Any zone shall be provided with the independent switch control button in addition to a button for the operation of all such six zones. There is the LED digital tube display screen, which is used to display the working status of the equipment.
Integrating the whole set of the broadcasting program as the small-sized public address system including the sound source, zone, preamplifier, post power amplifier and volume control and other functions, this equipment is applicable to the sites needing the public address by the small- sized public broadcasting system.
