Featuring: CM Series Bi-Directional Amplifier (BDA)

  • Continuously monitors its operation for instability and responds by reducing gain of the amplifier.
  • Automatic Gain Control (AGC) lowers the amplifier gain in order to reduce strong signals.
  • The overload shutdown with automatic recovery feature detects very strong signals that cannot be adequately controlled by the AGC. The amplifier will disable itself and then attempt to recover. The amplifier is active for a very brief period of time (<30 millisec.) until the overload condition is eliminated.
  • Higher power output than other amplifiers in its class.
