Fluent Spanish Speaker Needed to Translate?

What adapters are needed to plug plain speaker wire into a computer's speaker output?

  • Hello. Before I begin I feel the need to remind everyone that this is my setup and I am not planning on changing it, even if you give me suggestions on how to get a better system. I recently purchased two in-ceiling speakers and two 50ft lengths of speaker cable to use with them (I already mounted the speakers and have the wires routed how I want them.) However, I want them all plugged in to the same computer and all running mono. The computer has the green, blue, and red ports on the back, which I presume to be speakers, line input, and microphone (not important.) How do I take two sets of right/left speaker wire (just the bare wire right now, not even any banana plugs yet) and have them all connected to the computer so that they all receive equal sound output? Please be detailed, as I am new to audio systems (I usually just use the built-in speakers as programming is my fancy.)

  • Answer:

    No such adaptor exist. Well, it does but it's called an amplifier. Speakers are composed of a coil in a magnetic field... a linear motor. Key word is motor, it requires power. The output on your sound card is not designed to drive a speaker directly. Basically you are asking for an adaptor to connect the gas pedal in your car directly to the wheels so you don't need an engine. It simply doesn't work that way. You could try something like this... http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-383 mk

You need a receiver to power the speakers, and to route the desired signals to where you want. Computers do NOT have any audio amplifiers with which to drive speakers, which is why small desktop computer speakers have a tiny amp built into one of them. But, to run speakers such as what you describe, such a tiny and weak amp won't come close to doing it. So, buy a receiver, run the speaker wires to it's speaker outputs, and use a cable with a 3.5 stereo male plug on one end and twin RCA male jacks at the other. Put the 3.5 plug in the speaker out of the computer, and the twin RCA jacks into an audio in on the receiver. That's how my desktop is plugged into the home theater audio setup I have in my office. A good basic receiver would cost about $200, like a Pioneer 521K at Amaz*n.
