1、家庭影院介紹：
1. Introduction to home theater
一般可以分為：杜比定向邏輯環繞聲、THX、杜比AC-3、DTS、SDDS五種家庭影院。
Generally can be divided into: Dolby directional logic surround sound, thx, Dolby AC-3, DTS, SDDs five kinds of home theater.
家庭影院一般包括：AV信號源、AV放大器、AV音響、大屏幕顯示設備。其中AV放大器一般可以控制十多種不同的音頻和視頻設備，能夠切換各種視聽信號，改變各種聲場模式，并對各聲道信號的音量、混響、延時等進行控制。
Home theater generally includes: AV signal source, AV Amplifier, AV audio, large screen display equipment. Among them, AV amplifier can control more than ten kinds of different audio and video devices, switch various audio-visual signals, change various sound field modes, and control the volume, reverberation and delay of each channel signal.
2、CHP的家庭影院：

3、防磁音箱：
3. Antimagnetic Speaker:
此種音箱可以防止音箱內的磁場外瀉，防止對電視圖像的干擾。
This kind of speaker can prevent the leakage of magnetic field inside the speaker and the interference of TV image.
防磁音箱一般采用雙磁體全對稱屏蔽磁路系統，即在原磁鋼上加裝一塊極 性相反的磁體，并在揚聲器磁體周圍加一層防磁屏蔽鐵罩。
The diamagnetic speaker generally adopts the double magnet full symmetrical shielding magnetic circuit system, that is, a magnet with opposite polarity is added to the original magnetic steel, and a layer of diamagnetic shielding iron cover is added around the magnet of the loudspeaker.
鑒別是否防磁，可以將電視置于AV模式藍背景下，將音箱在電視上面移動，觀察電視是否磁化，也可將大頭針放在揚聲器周圍，優良的防磁音箱應不吸。
To identify whether it is antimagnetic, you can put the TV in the AV mode blue background, move the speaker on the TV to observe whether the TV is magnetized, or put the pin around the speaker. Excellent antimagnetic speakers should not absorb.
CHP家庭影院的音箱都是防磁音箱，一般在靠近電視時不會有影響，但一旦有干擾，請將電視關閉30分鐘，并使音箱離開電視。
The speakers of CHP home theater are all antimagnetic speakers, which will not affect when they are close to the TV. However, in case of interference, please turn off the TV for 30 minutes and leave the speakers away from the TV.
