Connect Your Mac To Your Stereo
Step 1 - Locate the audio output
Locate the audio output port on your Mac. Most Macs have a mini-plug output on the sound card at the back and the front of the computer. This is the same port you use to plug in head phones.
Step 2 – Plug cable into your Mac
There are different types of audio cables available; you need a cable with the 3.5 mm TRS connector at one end and a RCA connector at the other end. Although most Macs and stereos have the option of 3.5 mm TRS connectors, it is best to take a look at the outputs and inputs on your Mac and stereo to make sure you have got the right cabling. Look at the image at left to see how a 3.5 mm TRS and RCA connectors looks like.
Once you have got the proper cable, plug the TRS connector into the audio output of your Mac’s sound card or into the audio output on the front of your computer.
Step 3 – Plug the other end of the cable to your stereo
Locate the audio input ports on your stereo system. There will be quite a few ports and one or more will be RCA female connectors. Simply plug the RCA connector of the cable into the RCA input port on your stereo system.
Make sure you are plugging the cable into the input ports, as the RCA input and output ports on all stereos look very similar. The input ports say “input" or “in" next to the port. You can use the “Aux" in or “Auxiliary" in, or if it is already in use by another device, you may use “CD/DVD" or anything else except PHONO.
That is it! Your Mac is now connected to your stereo.
This connection will allow you to amplify and listen to your Mac’s sound on your stereo, as well as record audio (DAT, mini disc) on your Mac and stereo (MP3, movies, games, etc)
