Do not open the amplifier to connect the speakers and plug audio equipment. All wiring and input sockets and unplugging should be carried out in the off state, so as not to damage the equipment.
The second thing to do is to maintain the DVD player. The DVD player can be said to be a very fragile piece of equipment. In the daily must pay attention to the following points. Heat: the diskette player should be placed in the absence of sunlight, away from other sources of heat and heat radiation, and ventilated dry place.

Avoid heavy pressure: Do not place heavy objects such as TV sets directly on the amplifier or the disk player. Prevent interference: when receiving TV, radio, good to turn off the disk player to prevent noise and snow interference. Good hygiene: When cleaning the machine, avoid using volatile solvents and water, use a dry cloth to wipe the machine lightly.

Non-professional maintenance personnel should not open the top cover of the machine to avoid electric shock and eye injury by the disk drive laser.
Lastly, there is the protection of the speakers. Speakers are the terminal of the home theater sound, the quality of the system has a great impact on the sound quality, in order to reduce the lead on the signal attenuation, should try to use a thick special speaker wire to connect. Wiring positive and negative correspondingly do not reverse, when in use, the volume of the amplifier should not be opened too large, to avoid overloading the speakers.
