1. From the perspective of category, line array speakers are long-range
speakers, while ordinary speakers are short-range speakers.
2. From the perspective of power, the power of line array speakers is
mostly divided by 3, while the power of ordinary speakers is mostly divided by
2.
3. From the perspective of applicable occasions, the sound of line array
speakers is linear, which is suitable for large-scale party sound reinforcement
outdoors, and sound factory and ordinary speakers are suitable for indoor
celebrations or home use.
4. From the perspective of sound coverage, line array speakers have wider
sound coverage, and multiple speakers can be combined into a speaker group with
the same amplitude and phase.
Speakers (Guangzhou Audio Factory) are an important part of the entire
audio system, and their value is about half of the entire system, so they must
be treated properly.
①Avoid placing it in a place exposed to direct sunlight, and do not place
it near heat radiating appliances, such as stoves, heating pipes, etc., and do
not place it in a humid place.
② Before connecting the speaker to the amplifier, the power supply of the
amplifier should be cut off to avoid damage to the speaker.
③ The connection of the feeder with the amplifier should be secure, and it
should not fall off when being pulled, and the positive and negative polarities
should not be wrongly connected. The feeder connecting the loudspeaker should be
thick enough and not too long to avoid loss and deterioration of the damping.
The maximum deviation frequency response is ±0.5dB (the maximum length of
0.75mm2 wire is 9cm, the maximum length of 1.5mm2 wire is 14m, and the maximum
length of 2.0mm2 wire is 21m.
④ Pay attention to whether the impedance of the speaker is suitable for the
recommended value of the amplifier
⑤ Do not use it beyond the rated power. Otherwise the sound quality will
deteriorate and even damage the speakers. gae
⑥The shell should be wiped with a soft, dry cotton cloth, and do not apply
furniture wax or benzene or alcohol.
⑦The dust on the speaker surface can only be removed with a soft brush, not
with a vacuum cleaner.
