How to Connect Altec Lansing Speakers

By James Clark

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.

Things You'll Need

  • Altec Lansing speakers
  • Audio cables
  • Electronic device such as a computer or TV for connecting the speakers.
  • RCA jacks to mini-plug Y-adapter

Step 1

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.

Step 2

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.

Step 3

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.

Step 4

Insert the mini-plug on the right-channel Altec Lansing speaker into the mini-jack on a Y-adapter for converting the plug to full-size RCA audio plugs, then connect the RCA plugs on the Y adapter to the Audio OUT jacks on a TV or other device with standard RCA jacks. Use the white plug on the adapter for the left-channel connection and the red plug for the right channel.

Tips & Warnings

  • Connect multiple Altec Lansing speakers to an Altec Lansing subwoofer with specially marked jacks on the back for each speaker. The Audio IN cables on the subwoofer then connect to a computer, TV or AV receiver.
  • Disconnect all electronic equipment from the power while hooking up audio cables to prevent a blown speaker or short-circuit.
