    I just realized you may be asking the question the wrong way, simply because you don't know how audio computer connectors can be assigned by the user.

    So, I'm inputting this possible solution under the classification "I have the same problem."

    What you REALLY may need to ask is "How do I modify my computer's Blue, Green, and Pink audio connectors so they output 5.1 sound signals?"

    You see, the basic issue is that these 3 connectors are multi-purpose.

    This may be your situation and why you can only get your "Green" connector to output an audio signal.

    Of the 3 "audio" connectors on most recent computers, here is how the rear-panel audio connectors are usually configured by default.

    Green=Stereo Line-output, front speakers, headphones
    Pink...=Stereo Microphone Input
    Blue...=Stereo Line-input

    As in your case, that means that no matter how your system software settings are configured, you will always have an audio signal OUTPUT on the Green connector. However, your Pink and Blue connectors may be configured as INPUT connections for a microphone and another device such as an external stereo device like an iPod output.

    However, you can configure your computer SETTINGS to change how these 3 connectors are used. On some computers, you may have to change an internal motherboard jumper or 2, but on many computers, this is a strictly software change and very easy to do from the keyboard. This will let you connect the Dell 5650 5.1 Amplifier (or any other 5.1 amplifier with similar connector) to your computer and have full 5.1 sound output the way it is meant to be.

    This will change the connectors from the above Default usage, to

    Green=Front Line Output
    Pink=Sub/Center Output
    Blue= Rear Line Output

    Your computer user guide will instruct you how to do this. If your computer has both front and rear audio connectors, the rear connectors are usually set to the 5.1 audio output, whereas the front connectors remain set to Microphone, Line-in, and Line-out. Again, internal motherboard jumpers may be involved depending on the model of computer.

    On MY computer, I had to do this. It can vary depending on your Operating System, your audio drivers, your motherboard, and/or your sound card, so I can't give you a single set of instructions. But, the process will be something similar to this. Using the mouse, click on the following:
    StartButton>>Settings>>ControlPanel>>Sound Effects Manager>>SpeakerConfiguration
    Then, when I'm on that tab, I individually set the Blue, Green, and Pink connectors to be "Rear Speaker Out", "Front Speaker Out", and "Center/Sub-woofer Speaker Out" respectively. I then click "OK" and those 3 connectors now OUTPUT the audio signals for 5.1 sound needed by the Dell 5650.

As I understand it, this adapter is used ONLY to adapt a standard 2-channel stereo output to the 3, 1/8" plugs of the Dell 5650 5.1 system. These 3 plugs would normally plug into the front, rear, and center/sub outputs on a computer designed to output 5.1 channel sound.

To make this clear, what this means is that the output you get from your 2-channel stereo system, using this adapter with the Dell 5650 5.1 system, will NOT be full 5.1 surround will be 2-channel stereo signals intermixed so that it plays from the 5650 system through the Dell amplifiers and speakers...nothing more.

This cannot be over-emphasized. The adapter does NOT create true 5.1 sound from a 2-channel stereo output system.

If you are hoping to get true 5.1 output from a 2-channel stereo system, you will be disappointed.

All this adapter likely does is split/mix some of the 2-channel signal into the rear channel, and split/mix some of the SAME 2-channel signal into the center-sub channel, just so you will get some output from those speakers. There may be some low-pass filtering for the sub-woofer input.

It is almost certainly a very simple passive circuit consisting of resistors, capacitors, and possibly an audio transformer or two.

Look for circuit on Do-It-Yourself electronic sites and build it yourself...or you're almost certain to be ripped-off.

    More information:
    To see what this adapter looks like, and how it is used, see this webpage

    Download the appropriate .pdf file for your language. The adapter and how it is used is shown in the lower right corner of the document. As can be seen, it is used to adapt a standard 2-channel stereo output from various audio devices to the Dell 5650 inputs. From the images provided, it is a 100% passive adapter as I suspected in my earlier comment, and should be extremely easy and cheap (less than US$10) to make with simple electronic soldering skills.

    I just tried this and it worked "OK". Use at your own risk. It's a dirt-simple method of getting the 2 channel stereo to play on all the speakers of the 5650 system.

    I took 2 "Y" stereo adapters (off the shelf items (e.g. RadioShack) I got them for about US$4 each), and connected them like this. Picture it as the bottom "tail" of one "Y" stuck on to one of the top "antlers" of the other "Y" adapter.

    It works but remember that it doesn't produce 5.1 output, it just outputs the 2 channel stereo from all the speakers of the 5650. It sounds "better" than just a 2 speaker system, but personal preference will make a huge difference.

    The first Y adapter male 1/8" input connects to the headphone stereo output of my CD player.

    The "Front" cable from the 5650 goes to one of the female 1/8" outputs from this first Y connector.

    The 2nd Y adapter male 1/8" input connects to the remaining female 1/8" output from the first Y connector.

    The "Rear" cable from the 5650 goes to one of the female 1/8" outputs from this 2nd Y adapter.

    The "Sub/Center" cable from the 5650 goes to the remaining female 1/8" output from this 2nd Y adapter.

    It is important to note:

    1) Your stereo device electronics may not "like" being loaded to multiple inputs like this. It is POSSIBLE the stereo output on the device (CD player, etc) could be damaged.

    2) the input connectors on the ends of the "Y" adapters will depend on what kind of output connectors YOUR stereo system uses.

    3) that the "rear" speakers are getting exactly the same signals as the "front" speakers. There is no audio delay such as you would experience in a true 5.1 signal.

    4) that the "sub-woofer" is getting a signal ONLY from either the left or right channel of the stereo input, and the "center" speaker is getting a signal ONLY from the other channel of the stereo input. The sub-woofer is also getting the full spectrum of frequencies from the stereo signal. That's not necessarily a bad thing as the Dell amplifier may have its own low-pass filter. Either way, it won't damage the 5650 sub-woofer. This is where the "mixing" components mentioned in earlier comment would come in (capacitors and resistors) to blend the 2 outputs so that the "sub-woofer" and "center" channels get a bit of signal from both the left and right channels.

Forget the colors yellow, green, black. They are not relevant. The business end of those colors occur inside the box. Dell manufactured these "bass ackwards". You need a 3-way headphone splitter and that will solve your problem. I bought a RadioShack Headphone Splitter Cable model 42-2458. Hope this helps.

Hi Gracie,
If you're taking about the 3 into 1 adaptor for the 5650 it should have come with the speakers. I suggest you call Dell customer care with your order number and explain that you didn't receive this!!

How can I hook up the 5650 system to my lap top?

The laptop has one RT/Left mini port on the side or up front. You may require and adapter to a larger stereo plug if the Mini Adapter is too small for the speaker line input. If you have Two wires to the speakers and no Mini-Plug, you need Converter from Mini Plug to Right and Left Ports. Best you take it with you to RadioShack and they will match up the adapter you need then and teher.

Need a 3.5 mm audio cable adapter that originally came with this speaker set. It is an 3 to 1 adapter, meaning you connect the green, black and orange inputs into the adapter than turns into 1 black...

Your speakers are for a 5.1 sound system, thats why you have the diffrent channels (green, black & orange). Ideallly you need a sound card that can give you this output and the motherboard will be having those same colours as well.

If your PC did not hvave this, then you should not have spent your money on such expensive spaekers.

In the mean time just use the green connector and you should have a few of your speakers and the subwoofer playing.

Sorry about that mate.

Is there a way to connect my Dell MMS 5650 speakers to a Macbook Pro laptop or a wireless router? Where can I find cables for converting? Thanks!

The speakers should directly connect to the "line-out" socket on your Macbook computer, without any need for adapters.

I have _never_ seen a wireless router that had _any_ "audio" capability -- what you're asking for seems to be unreasonable.

Any "Dollar Store" or the "big-box" stores (such as Best Buy, Office Depot, Staples, Future Shop, Wal-Mart) should have adapter-cables.

Are these speakers adaptable with my Compaq Presario PC?

Hello my friend, with regards to your problem first we must check if your currentl audio device is compatible with your speakers. I mean you have a 5.1 speaker then let us check if your audio plugs is also a 5.1 channel in order to accomodate your speaker. else you can istall your speaker in to your currentl audio device but not all speakers were work cause it needs to have the same specs from your speaker to your audion device installed in your can only use the green, and blue then if you have mic the you could used the pink plugs but for your black plugs in your speaker it cannot be used.

Kia stereo in a ford ed

hi, first you are better off to purchase a conversion plug from a stereo outlet (so that you arn't cutting the standard plug off)
the colours should be
orange/pink = L/F Speaker
orange/black = L/F Speaker
grey/green = R/F speaker
grey/black = R/F speaker
pink/black = L/R speaker
pink/green = L/R speaker
blue/black = R/R speaker
blue/red= R/R speaker
blue/white = switched wire
black = earth
green/yellow = hot wire
these are ef but should be the same
happy motoring

Connecting Dell speaker system to TV or console


If you have a coaxial out on your TV and a coaxial in on your Speaker system that is the way to go to experience digital surround sound. Radio Shack, etc. has coaxial cables in the appropriate size. If you go to Radio Shack, etc. bring along your speaker system's model number as well as your TV's model number.

Hope this gets you going.
