Most Communications systems require an AC or DC power source. David Clark's Voice Powered System requires only your voice to generate the power needed.
When you speak, your voice travels to a transmitter causing fluctuations in a magnetic circuit. This creates a small amount of current (approximately 20 micro amperes), which is enough to operate the receivers on up to six headsets.
In its simplest application, a Voice Powered System can be just two Headsets and a jumper cord. For more headsets, greater distances, or portable applications, use David Clark jack plates, jumper cords, or junction box.
The David Clark C51-25 Extension Cord:
- Is 25 feet in length
- Is a two conductor cord with phone plug and phone jack
- Extension cords are used to extend distance from jumper cord, jack plate or junction box
- May be coupled for longer length
