               Thanks to its fully modular compositions, you can make up several
               Base Units configurations.
               As for the Unidirectional Systems, full-duplex systems can be mounted
               either in Portable Minirack (with different widths, depending on the
               required number of modules) and in standard 19”/1U or 19”/3U rack-
               frames. The Base Unit can be one single-channel or multi-channel type.
               The are available two types of Transmitters and Receiver Modules: in
               a vertical-shape (3U height) and horizontal-shape (1U height).                            CFK 50
               Regarding the output power of the Transmitters, we are used to offer

               The working frequencies can be set in two 7 MHz switching-windows
               between 400 ÷ 550 MHz, with a minimum distance of about 10 MHz
               between them.
               The Transmitter and Receiver Modules are endowed with a balanced
               and ground-isolated audio line connections. The audio input of the
               Transmitter has a very great input-level adjustment capability, to allow                  CFK 50-D

              Thanks to its fully modular compositions, you can make up several
              Base Units configurations.
              As for the Bidirectional Systems, unidirectional systems can be mounted
              either in Portable Minirack (with different widths, depending on the requi-
              red number of modules) and in standard 19”/1U or 19”/3U rack-frames.
              The Base Unit can be one single-channel or multi-channel type.
              The are available two types of Transmitters: in a vertical-shape (3U
              height) and horizontal-shape (1U height).                                               CTK 50
              Regarding the output power of the Transmitters, we are used to offer

              The working frequencies can be set in a 7 MHz switching-window
              between 400 ÷ 550 MHz.
              The Transmitter Module is endowed with a balanced and ground-isola-
