First, the power amplifier heat.
This phenomenon is normal, be careful not to place other items in the power amplifier (such as DVD, tablecloths, etc.) it is easy to heat.
Second, the speaker no sound.
1, first check the power supply is plugged in, equipment to resume normal power.
2, check the amplifier panel speaker A / B is open.
3, check the amplifier signal input device is adjusted in the correct location.
Third, glue stick using the stereo TV sound to play.
Use the audio cable to connect the TV and amplifier (TV output "line out / output" connector amp inputs "TV / DTV"; and adjusting the amplifier signal to the "TV / DTV" position; TV volume down to).
Fourth,glue gun there is not a sound only the voice.
Check the speakers and speaker cable is low-normal and properly connected, with or without the plug loose drag phenomenon.
Fifth, you are buying a BOSE leisure products, such as the remote control does not work there or key is invalid.
1 Check the battery has power.
2, reset the remote control center for music encoding (see instructions).
Sixth, the effect of differences between music and theater.
CD-ROM you purchased, CD labels are two-channel stereo format, standard DVD video discs are DTS \ Dolby decoding formats, poor quality or compressed audio disc does not belong to any decoding technology, so there is no sound of these discs is to talk about The.
1, cinematic: the standard DVD playback mode amplifier can be adjusted to DTS \ Dolby item.
2, the stereo effect: the amplifier model adjusted to stero (leisure products in the menu to switch channels) if the music CD you may want to use the stereo mode.
VII increase (decrease) bass or treble.
1, Tone Control Amplifier find key to find bass / treble adjustment mode can be.
2, BOSE AM series can be adjusted in the low speaker.
3, BOSE leisure products in the menu regulation.
Pat, why would burn my speakers?
1. We often use a microphone because of speech or singing too close to the microphone by the speakers or front speakers, turn up the volume high frequency positive feedback howling, which look to your speakers tweeter may not be brilliant. This is because the alt upon crossover after most of the signals sent from the pitch, all this high-energy signal through the circle put the horn tweeter very fine burned, so you used a microphone, do remember that the volume from the Tai slowly add, do not open big breath, so as not to damage the speakers and amplifier.
2. On a bad vibration too loud speakers will of course, another case is less hard to open loud amplifier power, the output signals are not properly cut, so will damage the speakers, we recommend a large volume of user preferences To buy high-power amplifier.
3. Amp DC output if it will burn subwoofer, even a very small number of loudspeakers will be burned. Reason is the bass (or other-way) speaker crossover capacitor path is not isolated DC, the DC output is like a pass into the speakers in the DC, even with the crossover coil burned charred. Therefore, they should be careful when purchasing the amplifier, before the first class and the power meter measures the output after the class if the DC output, DC output if the first level there may also be further amplified by the output level after the current incoming speaker.
Nine, get the power clean, quiet and transparent with level.
Living in the city, our house is full of a variety of electronic interference pollution. In order to reduce these disturbances, we try to make refrigerators, air conditioners, dehumidifiers, washing machines and other electrical circuits do not have the motor and sound loops together. If you can brace for power, of course better. In addition, there is a sell some resistance to electromagnetic interference and radio frequency props, there are a variety of power filters, processors can use.
How to determine your own clean power get it? Very simple power supply more clean, sounded more clear, quiet, transparent, and layering the better. But one thing to pay special attention to the past, many more people with sound thinner, and finally only clear and dry as the alto, tenor and not thin, rich, bass, this is not right. The correct sound should be the water of sweet treble, tenor and full plump, low volume foot and elastic.
X. burning machine.
Similar to the so-called burn in the run-in period mechanical machines, audio equipment will work after a certain time, the temperature inside the machine and the environment at the same temperature, the working status of the amplifier at all levels to achieve the best point, then replay the sound for the most good.
XI speakers clean.
Available soft, dry cloth to clean the speaker system, do not put in the system side of the liquid into spray or allow any open place, you can not use any chemical solvents or drugs, or use alcohol, ammonia or liquid sandpaper cleaning machines, satellite audio network cover with water cleaning, pay attention to is the drive after the guards, removable to be careful.
Second, the speaker connections.
1. Do not directly connected to the satellite audio amplifier output, to connect the satellite speakers sound and low, and then connected to the amplifier on the low speaker.
2. Do not use broken or frayed wires, or cause system damage.
3. In connection before you turn off your amp and cut off the connection with the AC power outlet, otherwise it will result in system damage.
4. Do not directly connected to the TV speakers will be low, unless it has surround sound decoding circuit system or the whole channel preamp output.
5. Do not let the bare speaker lines are met, this will damage your amplifier.
Thirteen normal operating temperature.
Audio equipment should be the normal working temperature of 18 ℃ ~ 45 ℃. Temperature is too low will reduce the sensitivity of the machine; the temperature is too high can easily burn out components or to components of premature aging. Avoid direct sunlight audio equipment, but also to avoid the near heat sources such as heaters, refrigerators and so on.
Fourth, the machine should be used.
Common but can extend the life of the machine, such as some with the Ministry of the motor body (tape deck, CD CD player, DVD laser discs, etc.). If you do not turn the long-term work, some parts will be deformed.
Fifth, to periodic power.
In the case of long-term is not used, especially in the wet, hot season, the best power for half an hour a day. This component can be used inside the work to get rid of the heat generated when the moisture, to avoid internal damp, moldy.
