Marratech requires a broadband connection with at least 256kbps
download speed and 128 kbps upload speed.
The faster the computer and the Internet connection the better the experience will be.
Marratech works fine over Cable, DSL, T1, FiOS.
A dial up connection will not work.
A cell phone wireless modem connection will not work.

then click here to
install the Webcast client. In the future, you can simply launch the
Marratech Webcast client and then copy and paste this URL to get into the
Build-It-Yourself room.
http://207.244.118.11:8000
It may
take up to 30 seconds before you see a loading screen. When loading is
complete, you will see a screen like the one
below.
Microphone:
When you click on the microphone button, it will turn red. When you
talk, you should see the volume indicator flicker.
You may need to adjust
your microphone and speaker volumes. On a Windows computer, go to
Start / Settings / Control Panel / Sounds and Multimedia. Select the
microphone and speaker drivers you are using. Then adjust the volume
controls. A good way to test both microphone and speaker
together is to launch your system Sound Recorder.
