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).
