How to use the maintenance speaker correctly

The speaker is an important part of the entire sound system, and the value is about half of the whole system, so it must be treated properly.

â‘  Avoid placing it in direct sunlight, not near heat radiation equipment, such as stoves, heating pipes, etc., or in a humid place.

â‘¡Before connecting the speaker to the amplifier, the power of the amplifier should be cut off to avoid damaging the speaker.

③ The feeder of the amplifier should be connected securely. It cannot be dropped when pulled, and the positive and negative polarities cannot be connected incorrectly. The feeder connected to the speaker should be thick enough and not too long to avoid loss and damping. Respond to the maximum frequency deviation of 0.5dB (8 children's stalks ┪? Trace?

â‘£ Pay attention to whether the impedance of the speaker is suitable for the recommended value of the amplifier

⑤ Do not exceed the rated power. Otherwise, the sound quality will deteriorate, or even damage the speakers.

â‘¥The shell should be wiped with a soft, dry cotton cloth, and do not apply furniture wax, benzene or alcohol.

⑦ Dust on the surface of the speaker can only be removed with a soft brush, not with a vacuum cleaner.

⑧Speakers should be placed on a solid, strong floor to avoid bass attenuation. Do not place the speakers too close to the wall.

⑨Do not place the speakers too close to the turntable to avoid howling due to acoustic feedback.

â‘©If there is mid-range and treble level adjustment, it can be adjusted according to the listening requirements to make the playback satisfactory.
