Some computers now have a single TRRS 3.5mm jack which combines mic input with speaker output instead of the tradition two jack approach (one jack for mic input and the other for speaker output).
The traditional jacks are TRS.
The Voice Tracker array mics have TRS 3.5mm stereo connectors.
In order to connect to a computer with a single TRRS jack, a TRS to TRRS adapter is required.
A better approach might be to use a 3.5mm TRS to USB adapter like our part 102B.
The sound quality thru USB may be better than the sound quality of the computer’s internal sound card.
Both the TRS to TRRS and TRS to USB adapters are reasonably priced
