The number of plugs depends on the size of the unit. Also, an additional cable passage plug is located at the base of each optional window component.
Access for communication cables (microphone, headphone, speaker, etc…), electrical cables and computer cables is accomplished by way of slotted rubber plugs. Simply remove the plug, insert the cable(s) into the slots and re-insert the plug into the wall. Two or more cable passage plugs are provided with each WhisperRoom™ and each will accommodate multiple cables.
