This is a normal phenomenon. Please be careful not to place other items (such as DVDs, tablecloths, etc.) on the amp for easy cooling.
Second, the speaker does not sound
1, first check whether the power is plugged in, the device can be normal power.
2. Check if speakerA/B is turned on on the power amplifier panel.
3, check the power amplifier signal input device is adjusted in the correct position.
Third, TV sound using audio to play
Use an audio cable to connect the TV to the amplifier (TV output “output†is connected to the “TV/DTV†input of the power amplifier; and the power amplifier signal source is adjusted to the “TV/DTV†position; the TV volume can be turned down).
Fourth, there is no sound
Check whether the speaker cable and the speaker cable are normal and correctly connected, and whether the plug is loose.
V. You purchased BOSE leisurely products, such as the remote control does not work or the button is invalid
1. Check if the battery has electricity.
2. Set the remote controller's encoding to the music center again (see the manual for details).
Sixth, the difference between music and theater effects
Among the CDs you purchased, CDs are in 2-channel stereo format, standard DVDs are in DTS/Dolby decoding format, and poor quality or compressed CD sounds do not belong to any decoding technology, so these types of discs have no sound effects. of.
1, the cinema effect: Play standard DVD can adjust the power amplifier mode to DTS \ Dolby items.
2. Stereo effect: Adjust the amplifier's mode to stereo (a leisurely product can switch channels in the menu) If you are enjoying a music CD, you better use stereo mode.
Seven, increase (reduce) bass or treble
1. Find the ToneControl key on the power amplifier to find the bass/treble mode adjustment.
2, BOSEAM series can be adjusted on the low speaker.
3, BOSE leisure products are adjusted in the menu.
What is the reason for burning the horn?
1. We often use the microphone to speak or sing because the microphone is too close to the speaker or facing the horn, and the loud sound is generated at high volume. The whistling sound of your high-frequency speaker may not work. This is because most of the signal after the treble is sent out from the treble after the treble. This kind of high-energy signal burns the horn through the extremely thin treble unit, so when you use a microphone, remember the volume. Gradually increase from the maximum, do not open big in one breath, so as not to damage the speakers and amplifier.
2. Too loud to sound will cause the speaker to vibrate. In the other case, the power of the amplifier will be hard and loud, and the output will be abnormal cutting signals. This situation will also damage the speakers. It is recommended that users prefer high-volume speakers. To buy high-power amplifiers.
3. If the amplifier has a DC output, it will burn the woofer, and even a few tweeters will burn. The reason is that there is no capacitor isolated DC in the bass (or other sound path) horn split path. The DC output is like direct current into the horn, and even the splitter coil is burned to black. Therefore, when purchasing an amplifier, you must pay attention to using an ammeter to measure whether the output of the front stage and the rear stage has a direct current output. If the front stage has a direct current output, it is possible to pass the direct current to the horn via a post-stage amplified output.
Nine, power clean, quiet and transparent
Living in the city, our home is full of all kinds of electronic interference pollution. In order to reduce these interferences, we try to keep the electric circuits of the refrigerator, air conditioner, dehumidifier, washing machine, etc. with the motor not to be in the loop with the sound. It's certainly better if you can pull a dedicated power supply. In addition, there are small props that sell anti-electromagnetic and radio frequency interference in the market, and there are various power filters and processors that can be used.
How do you tell if your power supply is clean? Simply, the cleaner the power, the clearer, quieter, and clearer the sound will be, and the better the layering will be. However, we must pay special attention to the fact that in the past, many people treated their voices more and more thinly. In the end, only clear and dry midrange, thin midrange and rich bass were left. This is wrong. The correct voice should be treble water and sweet, full full midrange, low volume and flexible enough.
Tenth, take the opportunity
The so-called hacking machine is similar to the running-in period of mechanical machinery, that is, after the audio equipment works for a certain period of time, the temperature inside the machine is the same as the ambient temperature so that the working conditions of the amplifiers at various levels reach the optimum point, and the sound reproduced at this time is the most good.
Eleven, speaker cleaning
Use a soft, dry cloth to clean the speaker system. Do not place the sprayer on the side of the system or allow liquids to infiltrate any openings. Do not use any chemical solvents or medicines, or use alcohol or ammonia-containing liquids or sandpaper to clean the machine. Satellite Audio Network The cover can be cleaned with water. After the cover is taken care of, the driver must be handled carefully.
Twelve, speaker connection
1. Do not directly connect the satellite sound to the amplifier output. Connect the satellite sound and the subwoofer first, then connect the subwoofer to the amplifier.
2. Do not use broken or worn wire, otherwise the system may be damaged.
3. Please turn off your amplifier and disconnect it from the AC outlet before connecting it. Otherwise, the system may be damaged.
4. Do not connect the low speaker directly to the TV unless it has surround sound decoding circuitry or a full-channel amplified output.
5. Do not let exposed speaker cables touch each other. This will damage your amplifier.
Thirteen, normal operating temperature
The normal working temperature of audio equipment should be 18°C~45°C. Temperature is too low will reduce the sensitivity of the machine; temperature is too high, it is easy to burn out components, or to make components earlier aging. Audio equipment avoid direct sunlight, but also to avoid near the heat source, such as heaters, refrigerators and so on.
XIV. Machines should be used frequently
Commonly used to extend the life of the machine, such as some with a motor body (recording, CD CD player, DVD laser disc player, etc.). If you do not turn the work for a long time, some parts will be deformed.
15, to be regularly electrified
In the case of long-term non-use, especially in wet, hot seasons, it is best to energize for half an hour every day. In this way, the heat generated during the operation of the internal components can be used to drive off the moisture and prevent internal moisture and mildew.
