Description of Product
PA2106/PA2116 is advanced public address equipment integrating MP3 player, FM tuner,
partition manager (6 partitions), 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 partitions are subject to the output at the constant voltage of 100V. Any partition shall be
provided with the independent switch control button in addition to a button for the operation of all
such six partitions. 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, partition, 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.
Features
Combined power amplifier series with MP3, radio playing function and integrating
the output of six partitions and the preamplifier and post power amplifier.
Plugged with U disc, SD card and other memory equipment to provide MP3 sound
source.
Two microphone inputs, three Line inputs, and one Line output for link.
Transform the output into 6 zones.

MUTING FUNCTION
This equipment provides muting function. The inputs from Mic2, Line1, Line 2＆Line3 are
automatically muted by a input from Mic1, as the signal from
Mic1 overrides other input signals. The level of MUTE can be
adjusted within the range from MAX to MIN by adjusting MUTE
control button on the rear panel. It is preset at MAX before
shipping from the factory.
PRECAUTION OF INSTALLATIOM
1 Do not block ventilation holes.
2 The amplifier should not be placed in any of the areas:
1) With poor ventilation;
2) Exposed to direct sunlight;
3) With high ambient temperature or adjacent to heat-generating equipment;
4) With high humidity or heavy dust;
5) Susceptible to vibration.
3 Make sure the power outlet conforms to the plug of the unit.
4 Do not use this unit if the electrical power cord is frayed or broken.
5 Always operate the unit with the AC ground wire connected to the electrical
system’s ground.
6 If an alarm rings after the power has been on and the signal has been fed, there
must be an output short-circuit trouble. In such a case, please turn the power off.
Do not turn on the power again, until the trouble shall be resolved.
