Now more and more families will complete the purchase of home theater, but few home theater equipment maintenance. Speakers as an essential part of a home theater, but also worthy of our maintenance da ~
Today, Granville electronic teach you the recipe how to care for speaker
A. Initial use must pay attention to check
The first time you boot, be sure to check all of the devices are connected, after determining the volume knob to the minimum and then reboot system.
If the system to issue a strange sound, the best off power, please professionals to debug.
If the speaker is not connected amplifier, it represents the road not turned on, so if the power of the speaker will cause irreparable damage!
II. Ambient temperature have a great influence on the sound system
The various components and other components within the speakers, the temperature is required.
Such as wood, paper of the cone, etc., the temperature is too high or too low will cause instability in the operation of the speaker components.
Ambient sound is generally used to control between -10 ℃ to 40 ℃, the temperature of the environment to avoid large fluctuations.
Range is too large temperature variations with the use of sound in the environment extremely low, it will be on the sound system caused irreversible damage.
III. Avoid the use of excessive sound, the microphone away from the speakers
When listening sure to check the wiring is correct, whether the potentiometer position is too large;
At the time of startup, shutdown, reboot and other operations, the volume of the speaker should be close to the minimum or the power is turned off to prevent large inrush current damage to the speaker;
Sing karaoke OK to try to stay away from the speaker, microphone and do not point the speaker, to avoid howling even burn tweeter;
Meanwhile, in order to protect the speakers, in general, applications do not speaker volume turned up too high, as long as enough, about 1/2 on it.
Volume suddenly increases the circuit, speaker damage; affect the life of the potentiometer,
Potentiometer internal structure is a flexible shrapnel contact with the carbon, if a long time in the same location may cause the carbon wear more serious point. IV. Speaker positions should note the following
1. The position of speaker should be placed to avoid direct sunlight, not the speakers placed in long-term wet places, so as not to rust or mildew coil.
2. Do not place the speakers too close to the monitor.
3. The speaker should stay away from strong magnetic fields.
4. Place the speakers on the computer under the table or stacked placement is very unscientific. The correct way is: the display is placed symmetrically around the center, and to ensure that the user is on the horn speakers, subwoofer because not highly directional, position can be flexible.
V. has started equipment
When using audio, first start the source device.
Usually in addition to the amplifier, we will select disc players and other audio equipment, has launched several devices in the process, particular attention should be turned off in order.
When √ boot, first boot disc players such as audio equipment and other pre-amplifier → reopened;
√ When the shutdown, first turn off after the pre-amplifier → equipment.
√ shutdown Shihai should sound volume to a minimum, not only can reduce the impact of the sound when the switch, and the next will not scare own boot. VI. Special socket, avoid electric plug
Many amplifiers will be set back one or two sockets for other equipment, the socket is absolutely dedicated to special seat, household appliances can not be used to connect to other high-power devices, such as iron and the like. Whether amp socket or behind your power amplifier plug, plug in the course will be charged to the system impact, damage to the body and speakers.
VII. Dust is the key speaker
Dust is the natural enemy of the speaker, it has enormous destruction. Although the speakers have adopted the sealed, but some brands with a separate subwoofer speaker, cables between subwoofer with its satellites, the card is by foot on the box above the line card. If you enter here a lot of dust, it will cause the connection between the speaker and speaker cable is not smooth, direct impact on the playback quality. Dust work to do so, from time to time under treatment please. VIII. Dehumidification work to put in place
Damp speakers speaker is the largest natural enemies, of course, it is also the natural enemy of all electrical products. If the speaker will damp the speaker diaphragm physically in shock metamorphism process, thus accelerating the aging of speaker diaphragm directly lead to a decline in quality. Also damp soft horn ring also exacerbate aging tattered edges, while the metal part of the internal speaker to let some of the rust corrosion, resulting in unexpected failure.
IX. When cleaning pay attention to water
Clean the sound does not recommend the use of water to wipe. Audio equipment with metal shell also more, and waterproof sound is very small, so the water can cause erosion of the shell, and conductivity of the water used to make detergents would be inappropriate. If you want to clean the body, do not use volatile solution type cleaning agents such as gasoline, alcohol and the like, try to choose a soft cloth to reduce scratches on the body.
X. speakers potentiometer is broken, how to repair?
Sometimes we potentiometer speaker a "Shasha" noise, then the best way is to replace the same brand and type of potential, you need to pay attention to the resistance potentiometer, linear.
Another way is for the potentiometer cleaning:
Recommend the use of ethanol (Please note that at least analytical grade anhydrous alcohol instead of medical alcohol) to clean the contacts of carbon and can be some small amount of high-purity tung oil or pine oil after cleaning, lubrication and protection play a role . In addition you can also use the more difficult to buy the VDH's TheSolution or may be used to clean oil.
