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 C52-50 Jumper Cord:
- Is 50 feet in length.
- Is all that is required to complete a two-man VOICE POWERED System.
- Is a two conductor cord with phone jacks on each end.
- Headsets plug directly into jumper cord.
- System can be lengthened further by adding extension cords to jumper cord.
