Setup of Audio-visual Equipment

Use of Polycom SoundStation without an analog phone line (e.g. in room 1-1-025)

You will need to use the “Mobile phone connection cable” to connect the Polycom to your computer directly (see accessories box).

A new Polycom conference phone is kept at Lucie's Office in its original cardboard box/carrying case. It includes all the relevant cables and should contain the Mobile phone connection cable

For relatively modern laptops (e.g. Macbook Pro after 2011, Macbook Air):

Usually there is only one jack for both Microphone and Speaker (i.e. a headset jack). In these cases, use the cable that has one black 2.5 mm jack leading to two 3.5 mm jacks (one white jack labeled “iPhone” and one Black jack labeled “Other”).

Connect the smaller (2.5 mm) jack to the Polycom. The port is on the left hand side of the unit and is indicated by a mobile phone symbol.

Connect the Black (“Other”) 3.5 mm jack to your computer. This was tested on a MacbookPro and a Thinkpad. If your laptop’s jack is non-standard, you may need to try the white (“iPhone”) jack. Start Webex as usual, but chose “Use computer audio” for your audio conference. Your laptop’s internal speaker and microphone should be automatically disabled and not used (tested on MacbookPro running Yosemite). Instead, the Polycom’s speaker and microphone are used. Try to use the setup as is by default (with automatic microphone level adjustment). If remote participants complain about hearing their voice echoing, you may need to manually adjust the microphone level.

If your computer has two different jacks for external Microphone and Speaker connections:

Use the cable with one black 2.5 mm jack leading to one green and one red 3.5 mm jacks. Connect red jack to microphone port and green jack to headphone port. Proceed as above.

General Tips

  1. Don’t use the Polycom’s “Mute” function. Some users have reported that the Red light Mute indicator may go away after some point and you may think that you are not muted while in fact the other attendees cannot hear you. If you want to mute your end, use the relevant Webex Mute function.
  2. You may need to play a bit with the Audio settings in Webex. For example, you may need to manually select the appropriate Microphone input on Webex, to make sure you are not in fact using your laptop’s onboard Microphone. Moreover, you may need to manually adjust the microphone level by deselecting the option to automatically adjust the level in Webex.

Settings known to work:

On Conrad’s Laptop: Use Black (“Other”) plug and in Webex, select the proper Microphone, namely use “Microphone (IDT Hi Definition …)” instead of the “Integrated Microphone Array”.
