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.
Behind-the-Head, Dual Ear, Acoustic Boom
David Clark H5040 Voice-Powered Headset features:
Headset with Acoustic Boom
This is a Behind-the-head version of Model H5030.
Soft adjustable overhead strap that fits under safety cap.
Recommended for Noise Levels to 100 dB.
Foam filled ear seals provide outstanding comfort and secure fit
30-inch straight cord and single plug, electrical connector
