2, check the amp panel speaker A / B is turned on.
3, check the amplifier signal input device is adjusted in the correct position.
Third, the TV sound using stereo to play
Using an audio cable to connect the TV and amplifier (TV output "Line Out / output" connection amplifier inputs "TV / DTV"; and to adjust amplifier signal source to "TV / DTV" position; TV volume down to).
Fourth, there is a sound not only sounds
Check the speakers and Acoustimass module cable connected properly and correctly, whether the plug is loose phenomenon.
Fifth, you are buying a BOSE leisure products, such as the emergence remote control does not work properly or invalid keys
1, check whether the battery has power.
2, re-set the remote control of the music center of coding (see instructions).
Sixth, the effect of the difference between music and theater

Eight speakers will burn what is the reason?
1. We often use microphones speech or singing because the microphone too close or in front of the speaker by speaker, high volume howling high frequency of positive feedback, which look your horn tweeter may not effective. This is because after a through crossover alt Most of the signals emitted from the treble, this high-energy signal through the full circle put the horn tweeter fine burned, so when your favorite microphone, do remember volume Slowly add the Tai, do not open big breath, so as not to damage the speakers and amplifiers.
2. The course will be open too loud bad vibration speaker, another situation is the lack of hard power amplifier open loud, are not normal cutting output signal, this will damage the speakers, we recommend that large volume of user preferences To buy high-power amplifier.
3. If there is a DC output amplifier, it must be burned woofers, tweeters and even a handful will be burned. The reason is the bass (or other audio channel) is not the speaker crossover path capacitor isolated DC, DC output as a direct current through the speaker, and even crossover coil together burned charred. So be careful when choosing to expand machine, the first electricity meter to measure the front and rear stages of the output of the DC output if there is, if the first stage has a DC output is also possible via the amplifier output stage and then the DC incoming speaker.
