Altec Lansing manufactures high-end, self-powered speakers for home audio applications, primarily personal computers and laptops. The speakers contain built-in amplifiers to produce quality sound without drawing electricity from the computer. Because they are self-powered, Altec Lansing speakers can also be connected directly to a television with an RCA adapter to improve on the TV's factory speakers.
Connect the mini-plug on the cable from the left-channel stereo speaker to the Audio OUT jack on the back of the right-channel Altec Lansing speaker. The plug inserts straight into the jack until it seats with a click.
Connect the mini-plug from the Audio IN cable on the right-channel speaker to the AUX OUT jack on a computer or the headphone jack on a laptop. The jack is on the back of the computer's Central Processing Unit (CPU) or along the left or right edge of a laptop.
Plug the CD power cord into the 12 volt jack on the back of the right-channel Altec Lansing speaker and connect the power transformer on the other end to a wall outlet. This completes the speaker connection to a PC or other electronic device with a mini-plug audio jack.
