With the degradation of major manufacturers' product promotions and home theater prices，The 易彤破壁机全国维修点 penetration rate of home theater is gradually improved。The home theater should pay attention to maintaining in daily life.，Below we will introduce some common sense for home theater equipment。
Home Theater Audio Maintenance
Audio maintenance and use very special，Once improper use，Otherwise it may damage the speaker。The following method，Can make your stereo more beautiful，Longer life。
1。 The normal operating temperature of the audio device should be18℃-45℃。Temperature is too low to reduce certain machines（For example, tubular machine）Sensitivity，Too high will easily burn the assembly，Or make the component aging。In addition，Pay special attention to cooling and keep air circulation in summer.。
易彤破壁机售后 2。 Do not expose the speaker in direct sunlight。Also avoid near the heat source，Heater。
3。 After the speaker is used，All function keys should be reset。If you have no reset function keys for a long time，Torsion spring long-term force，It is easy to cause malfunctions。
4。 Before opening or closing the audio power，Turn the volume potentiometer of the power amplifier to the smallest，This is the most effective protection method for power amplifiers and speakers。at this time， Power amplifier's power amplification is almost zero，Even misuse， Will not damage the speaker。
5， Open first when startingCDplayer，And adjust the volume potentiometer of the power amplifier to the smallest； When the power amplifier should be closed when the power is turned off，Let the amplifier amplification function completely closed，Then close the front end device，in this way， Even the pouring current is very large，It does not affect the sound。
6。 Clean a contact every six months。Metal exposure is in the air soon，Surface will be oxidized。Even the surface gold plating of the signal cable plug，Due to close contact with the body plug，long time，Still a certain degree of oxidation，Leading poor contact，therefore， Cleaner every six months。Just use the cotton cloth with alcohol to apply contacts。
7。Try to avoid machine stacking。the most importantCDPlayers and amplifier components should be placed as much as possible。Because overlapping placement can cause resonance and affect the machine。When playing music，Air vibration will cause the equipment to follow vibration，When two machines overlap each other， They communicate resonance in each other，Make the subtle information in music，And interfere with the transmission of each frequency band，Causes a sound pollution。therefore， It is best to place various devices in a stable rack.。
8。 The less interference，The better the sound。Other household appliances and computers should avoid sharing a power with the audio system。Even if you want to put them together, you should get power from other places.。In addition，Wrap wire also absorbs noise from each other。Destroy sound quality。and so，Whether it is a device or a cable, it should not be interfered by other electrical or power cords.。
9。 Sound sound should be appropriate。Furniture and debris in normal home environments are already excellent sound absorbing materials，No need to make sound absorption too complicated，Carpet has basic sound absorption effect。The advantage of adding a carpet is that the reflection of the floor can be reduced，Avoid getting the sound from the front，To avoid turbidity。When the speaker is too close to the back wall，You can also consider adding a tapestry，In order to increase sound absorption effect，But please pay attention to not use too much block，Apart from this， evenUHFWill be absorbed。In addition，Glass and mirror in the room strongly reflect the sound。It needs to be covered by a curtain。Harsh user，Many sounds are absorbed at the corners of the wall and the sound reflections in the room.。But pay attention to not over-sounding，The right amount of reflection sound helps the vivid sense of sound。
Home theater repair method
1。 Open and close audio equipment
Guide order：First openDVDplayer， tuner Record player， Equalizer Effector KarawaOKmachine mixer， Power amplifier front amplifier， Finally open the power amplifier。
Shutdown order：Contrary to the boot order，First turn off the power amplifier andDVDplayer，After turning off the speaker，Avoid cutting all power at the same time。Do not open the power amplifier to connect the speaker and insert an audio source device。All wiring and input sockets and unplugs should be carried out，To avoid damage to the equipment。
second， DVDPlayer maintenance
1。 Pay attention to heat：DVDThe player should be placed in a place without direct sunlight，Stay away from other heat sources， Heat radiation source Ventilated place。
2。 Pay attention to moisture：Avoid affecting humidity changes，Dry cleaning should be kept，To prevent dust and moisture from entering the machine。
3。 Prevent vibration：Do not use in places with vibration，DVDWhen the player is jitter，The error correction function will be affected。At the same time increase the search burden，Accelerate the aging of the bald head。Be careful when processing， Knock on the door collision， and many more Strict prohibited。
4。 Avoid withholding heavy duty：Do not take heavy objects（For example TV）Put directly in the amplifier orDVDPlayer。
5， Prevent interference：When receiving television and broadcasting，It is best to closeDVD，To prevent noise and snowflake interference。
6。 Do a good job in hygiene：Cleaning machine，Avoid using volatile solvents and water，Gently wipe the machine with a dry cloth。
7。 Correct connection：Connect or cancel any connection operation，First turn off the power。This prevents damage to the machine or other devices connected thereto.。
8。 Please keep your cable safely：Connect or disconnect the cable（Including AC power cord）Time， You should grab the connector to operate。Do not grasp the cable，To avoid damage to cables and electric shock。Non-professional maintenance personnel Do not open the top cover of the machine，In order to avoid electric shock andDVDPlayer's laser damage to the eye。
third， Speaker maintenance
The speaker is the terminal of the home theater sound，The quality of the system has a big impact on the sound quality，In order to reduce the attenuation of signal leads，It should be used to connect to the coarse dedicated speaker line.。Wiring Negotondes should not be reversed on the front and negative。The volume of the power amplifier should not be too large when using it.，Avoid overloading the speaker。
fourth， AVAmplitude and adjustment
AVThe amplifier is the core equipment of the home theater system，Many function adjustments are also very complicated， It is necessary to master the correct usage。Use Dolby Orientation Logic（Dolby Pro Logic）Decoded power amplifier operation，The first thing you should know，Dolby Surround Sound Square can only be recovered by playing video disc recorded in Dolby surround sound.。at this time， Directional logic status can be selected by a surround mode switch，Then select the mode mode according to the configuration of the speaker，E.g， Standard mode suitable for ordinary non-full central speakers； Broadband mode is suitable for hinning speakers，No central speaker，Phantom mode should be selected。And ordinary stereo audio and video disc，Only by means of digital sound field effect by means of power amplifier，That is， DSPPower amplifier analog cinema effect，For example, widescreen movies and mono movies。Different stylesCDOr disc in other places，AVPower amplifiers can also simulate different sound field effects，Common is the concert hall， life， rock， church， jazz， stadium Wait these can be set by surround sound effect selection switch。
5， Applicable placement position should be correct。
1。 Should be placed in ventilation， cool， Dry and clean place to avoid direct sunlight。
2。 Away from the transformer，Avoid 嗡嗡 cause noise pollution。
3。 In order to ensure good ventilation and heat dissipation，It is best to leave out at the top of the amplifier30Classical distance。On the left and right sides and the rear20Centimeter space。
4。 Magnetic objects should be avoided around the speaker。If it is not an electromagnetic speaker，Do not place it around the side of the TV。Since the magnetic field strength of the magnets of different speaker units，So there is no safety distance but usually take more than a TV.50cm。
5， Try not to place the object with the liquid in the top of the device。Decorative vase， Fish tank。
six， Pay attention to a few points when using。
1。 For maintenance consideration，Many friends will cover home theater equipment with dust 易彤破壁机维修网点masks，Most power amplifiers have a cooling hole at the top of the machine。So remove the dust cover when used，Improve heat dissipation。
2。 Most home theater equipment standby rarely。Usually less than0。1watt/hour，therefore，You can put home theater equipment in standby，Especially in the moist local standby current helps keep the amplifier inside dry。
3。 Power plugs that best unplug the equipment during thunderstorms，just in case。
4。 If you don't use the device for a long time，Should take out the battery in the remote control，Avoid battery leakage corrosion circuit boards。at last，Pay attention to when cleaning，When cleaning equipment，Do not use chemical solvents，You can use dry clean， Soft cloth。
