K-VA22/23 Coax Transmission

 
 

K-VA22/VA23 Transmission System consists of a K-VA22 Transmitter and companion K-VA23 Receiver working as a pair for: (1) transmitting video downstream while receiving headphone-level audio, and (2) receiving video while transmitting an amplified microphone signal upstream. The system works over a single coax cable. The K-VA23 allows selection between Condenser and Dynamic Microphones and provides a mic level control. The K-VA22 allows headphone level control. They allow, for example, a Director's comments to be transmitted to the Cameraman while receiving the video image on the same cable. A 12VDC power supply is included with each unit for typical operation. The K-VA22 and K-VA23 are part of the Kramer Tools family of compact, high quality, and cost effective solutions for a variety of applications.
