Music Files

Music files have revolutionized the way of listening to music, MP3 players or computer software designed to play music files, have made it easy and convenient to build playlists for any occasion or mood. Although compact discs (CD) programmable to allow some flexibility to create playlists, ease of clicking to add songs makes other forms of programming look archaic and restrictive. It is not surprising then that people prefer the option of using MP3 players to listen to music through the system. The most common and least expensive to listen to music from the computer to the stereo system is connect an RCA audio cable from the sound card in your computer to the stereo receiver. All sound cards are made with at least one line of output for the speakers of the mains unit. The connector is usually a 3.5 mm mini-phone connector A low cost adaptor that counts with a stereo jack of 3.5 mm on one end and two RCA female connectors on the other is required to operate, it connects to a standard RCA stereo cable, the opposite end of the cable may be connected to the radio or surround sound receiver. After the connection is made, adjust the volume before turning on the receiver.

Change the receiver mode for auxiliary (as opposed to radio, CD, DVD, TV, etc), and gradually turn up the volume. You may need to increase the volume of the MP3 Player control. Advanced sound cards can also have another line of output, such as Digital Out. The instructions are the same, instead of a digital cable to RCA cable. The receiver also needs a digital audio in port. Although wiring methods are cheap, they have the disadvantage of requiring a physical cable connected from the computer to the stereo.

If the computer is a desktop in another room of the stereo Centre or entertainment, this may be impractical. A laptop provides a good medium Mobile for music libraries, since you can set closer to the stereo system to simplify things and keep the wires out of aisles. Another method is the wireless technology, in this case, a small transmitter is connected to the line output port of the sound card, and a game receiver is connected to the audio in port on the receiver line. Computer music is silent dissemination through radio waves from the transmitter to the receiver. The receiver interprets the radio signals and translates them into an audible signal to play through the speakers of the entertainment center. Stereo wireless transmitters vary in design and pricing, some models include video ports compounds to send not just audio, but video signals between the computer and the entertainment center.
