R-Columbia's System 903 radio phones consist of 3 headsets with built-in transmitter, receiver 9v battery supply, and microprocessor. Available in Single and double ear headphones styles.

Each headphone transmits and receives on separate channels allowing users to communicate on an open line. R-Columbia's exclusive Circle of Silence "Noise Gate" feature blocks out unwanted acoustic noise caused by wind or background noise. Automatic gain control AGC adjusts to changing input level. A built-in microprocessor allows the selection of eight channel pairs, thereby avoiding frequency conflicts. Users will hear their side tone when speaking, confirming that transmission is taking place.

A flexible mini gooseneck boom allows adjustment of the mic for optimal performance. The mic boom rotates and can be operated from either the user's left or right side. Exclusive microphone conditioning circuits (compression and noise gating) are the secret to the outstanding vocal clarity of an R-Columbia's "open line" radio intercom.
