Polycom Soundstation 2W Computer connection cable

Polycom sell these and they come standard with the extended model. However if you have the base model, a standard stereo cable with 3.5mm plugs on each end and a soldering iron you can make your own. The base model comes with a 2.5mm stereo cable for connecting to a mobile phone, however most mobile phones in the UK have a 3.5mm jack so this is not of much use.

Cable assembly instructions

  1. Cut off one end of the 2.5mm cable. This cable contains three wires: red insulated wire is attached to the tip of the plug, the white insulated wire to the middle ring and the uninsulated wire to the base as shown in the figure below.
  2. Cut the 3.5mm cable in half. Again the cable should contain three wires, where typically, red insulated wire is attached to the tip of the plug, the white insulated wire to the middle ring and the uninsulated wire to the base. You can always check this with the continuity tester on a multimeter.
  3. The Soundstation 2W only has mono microphone output and sound input, so it is necessary to connect both the red and white wires together from the stereo output of the plug that you will plug into the PC headphone socket and similarly for the cable that you will plug into the PC microphone input. The required connections are shown in the figure below. If you plan to use heat shrink tube to cover the join don’t forget to slip this over the cable with the 2.5mm plug before you start to join the cables.
  4. Make sure you use some heat shrink tube or tape to insulate the speaker and microphone connections from each other
  5. Join all the uninsulated common wires together.
  6. Finally cover the join with heat shrink tube or tape.
  7. It is a good idea to mark the 3.5mm plug (the upper plug in the figure below) that is connected to the tip of the 2.5mm plug as the microphone plug (I put some heat shrink tube around the plug).

To use the SoundStation 2W with Skype you first need to put the SoundStation into IP mode. Press Menu, select IP MODE, press OK, press ON, press SAVE.

Then plug the 3.5mm microphone plug into the microphone input jack of you PC (typically this is colour coded pink) and the speaker plug into the headphone output jack of you PC (typically this is colour coded green).

Now plug the 2.5mm plug into the computer jack on the SoundStation (this is next to the power plug). The LCD display on the SoundStation 2W should now say MOBILE PHONE IN.

Now open Skype. You may need to go to the Call menu >> Audio settings and make sure that the microphone input is set to the correct source, and the speaker output is set to headphones

  1. Hi,

    Thank you very much for this article.
    Can you please let me know if this works for the “Polycom Soundstation 2” (not 2W) model also?

    Regards,

      • I confirm that it does not work for Polycom SoundStation 2 model. I created one chord with the above mentioned connection and the microphone almost does not work. The voice is noisy and the volume is very low. Also, it does not matter if I interchange the speaker and microphone jacks in sound card, ie, putting the microphone jack in sound card’s speaker socket and speaker jack in microphone socket work as well in the same state (speaker volume is good but microphone is bad).

        I suspect SS2 has a different connection and that may be the reason Polycom is selling different wires for SS2 and SS2W at: http://www.polycom.com/products/voice/accessories/computer_calling_kit.html

        So, can you please let me know how can I create a connection which will work with my 2W? I am open to experiments.
