That friend can help, find a potential home theater, a sound engineer, speakers do not want, it is best to Sujiatun, the audio division close to my house.
How to connect the power amplifier, computer, AV power amplifier, all kinds of interface connection methodHow can a home stereo connect to a computer?Sound box with amplifier, call active sound box, do not have amplifier, call a sound box. Method of active speaker is connected to the computer, using a 3.5 head plug on one end and a double plug connection, 3.5 head inserted in the headset output on the computer, a double head lotus head inserted in the audio input active speaker, will power on the speaker, the speaker of the volume knob to control the volume size. If the speaker does not have a power amplifier, it can not be directly connected to the headphone output, so the volume will be very small, it is necessary to increase the power amplifier.
All kinds of interface connection method of AV power amplifier"The armed forces did not move, forage first, here in about connection before the first talk about the various interfaces and the wire is connected with the power amplifier. It is now the digital transmission era, so here is only digital transmission, analog aspects are not mentioned for the time being. HDMI is now the most popular, and in many new products, the HDMI interface has become standard configuration. HDMI is a new generation of multimedia interface standards, there are HDMI 1, HDMI 1.1, HDMI 1.2, HDMI, 1.2A, HDMI 1.3 and other specifications, the new generation of AV power amplifier, HDMI interface has become necessary. From the beginning of the HDMI 1 specification, the HDMI organization defined support for DolbyDigita 5.1 (including Dolby, DigitalEX) and DTS (including DTS-ES). HDMI 1.1 adds support for DVD-Audio, and HDMI1.2 adds SACD functionality. HDMI1.3 adds to the new lossless digital surround audio format Dolby True HD and DTS-HD Master Audio support, so if you want to enjoy the next generation of real audio must be selected with HDMI 1.3 specifications of the power amplifier and the player.In addition, HDMI (except version 1) can transmit 8 channel 192kHz and 24 bit uncompressed audio, which is superior to all other consumer audio formats. Therefore, if the player can decode the audio format to a multichannel PCM, then any of the above audio formats can be transmitted in the form of a decoded PCM stream. In this way, many of the old A/V receivers that support multi-channel PCM audio transmission over the HDMI input interface can still be used to play updated Dolby, True, HD, and DTS-HD Master Audio formats.
Blu ray or HD HD player and ordinary power amplifier connectionIf you have a blu ray player or HD DVD player, so they must have been with HDMI interface (general new products with HDMI 1.3, before the product is likely to be 1.1 or 1.2), and they also have coaxial digital output and optical digital output interface, it and the general power amplifier (said here the common amplifier is non HDMI port 1.3, Dolby BTrueHD and DTS-HD do not support MA decoding amplifier) there are three kinds of access methods, and the three methods were suitable for all kinds of HDMI interface with the HD player, including HD player, HD set-top box, HD DV.(1) if your Blu ray player or HD DVD player with a HDMI output interface, HDMI interface and power amplifier not only, or coaxial optical fiber interface (general power amplifier has these two interfaces or one of them), then you will play is the connection method for the HDMI through the HDMI interface (TV input mentioned here are the TV with HDMI interface, if the TV does not have the HDMI interface by DVI, color line or S video input terminal, and below said here is the same, no special instructions), audio signal through the optical fiber and coaxial input amplifier.(2) if your Blu ray player or HD DVD player with a HDMI output interface, and amplifier with 2 HDMI interface (HDMI interface with the power amplifier is the most basic configuration of 1 HDMI input and 1 HDMI output), HDMI input interface then you is the output interface of HDMI player insert the power amplifier through the HDMI line, and HDMI output amplifier connected tv.(3) if your Blu ray player or HD DVD player with two or more HDMI output interface, and amplifier with HDMI interface, then you is the two HDMI player interface one input amplifier, a TV input. You can also use the method of (2) points.
