2. GENERAL DESCRIPTION
Speakers are compact waterproof speaker systems designed for high efficiency, wide range, and high power input
handling capability. These speaker systems can be installed in a manner ideal for the location and intended
application. The speaker is certified to the European Standard EN 54 24:2008.
3. FEATURES
• Wide directivity high-frequency horn.
• Supplied bracket permits mounting to a wall.
• Impedance change available by a rotary switch located in rear side.
• Certified to EN 54-24:2008.
4. IMPEDANCE CHANGE AND WIRING
To change the impedance, press the corresponding input voltage and power on the power label sticker indicated
on the cable and connect the corresponding cable to get the required input power.

5. INSTALLATION
Note: commercial audio installation system must conform to local building laws, when install speaker on wall or
ceiling, please consult a building constructer with a license or a professional engineer. The corporation won't be
responsible for the improper installation or damage because of not conforming to installation description.
Never install this product unto a motor vehicle.Never operate this product beyond its specifications, which might
influence its life span as well as performance
Installation procedure of bracket is very simple and convenient , the appearance is pleasing to the eye
step 1. The screw secures the horn "U" bracket to the wall. Wall material must support the weight of the cabinet
Step 2: Adjust the orientation of the "U" bracket according to the required mounting angle. This installation has
been completed.

OUTDOOR INSTALLATION DESCRIPTION:
NPJ series speakers are designed specially for fixing and using in different circumstances. The property of
speakers may be different due to different circumstances. There is an acoustic surface wall in a closed room, so
the acoustic indoor will turn complex. When acoustic wave hits the surface, a part of acoustic energy is reflected,
and others are absorbed. Reflection and absorption are depending on the frequencies of acoustic wave and angle
of hitting surface. When operate the cabinet, both man and furniture can absorb the acoustic energy. Please note
the position of man and furniture when installing. Reverberation is the results of the reflected acoustic wave
continue bouncing between the surfaces. Every reflection will loss the energy. When the acoustic hit the reflection
surface, the room will be filled with random reflected acoustic wave. The music and address will be complex. It is
recommended that install more speakers and make the volume of speakers lower to reduce the reverberation in
high reverberating room. (Please see figure 5B)
Speaker coverage range - Direct the center axile of the speaker to the flat surface of receiving area.
The speakers of 90˚x90󱔉series can spread the speaker tone to all the directions at the axile of 45󱔉.
If you use the speakers in large room, you can divide the room to some zones. Then decide the installing location
of the speakers . (Please see figure 6)

6. CONNECTION DESCRIPTION
LEVEL DISTRIBUTION SYSTEM CONNECTION DESCRIPTION:
NPJ-5 (EN54-24) and NPJ-5D (EN54-24) series have built-in transformer of 70/100V, can connect many speakers
to one channel, and only need one amplifier. The amplifier output terminal "com/-" stands for positive. The red
speaker terminal stands for positive, black stands for negative. Please connect amplifier to speaker right, incorrect
connection may cause damage to amplifier and speaker. Finally set your desired output power, See Figure 3A to
connect the cable to the corresponding power to meet your needs , in this case, the total power of all the speakers
can't exceed the nominal power of amplifier. One 320W amplifier channel can drive 12 speaker of 20W, i.e. 20 x
12=240<320W).For safety, the total power of all the speakers should be less than 3/4 nominal power of amplifier
(One 320W amplifier channel can drive 12 speakers of 20W, i.e.20 x 12=240W<320W).
