       Interphone system IS-05 provides two-way loudspeaker communication between a technologist and a drill operator at high noise boring station conditions.
       IS-05 is based modern electronics and enclosed in a compact metallic body. The main consumer preferences have been improved. The bell is equipped with an electronic microphone in order to improve speech intelligibility. The external influence protection system has a self-restoring protector with an embedded varistor and an extra discharger.
       Communication line short-circuit protection system, in addition to output amplifier protection, has a self-restoring protector.
      Additional features:
       The bell has a call button to draw the operator’s attention;
       To decrease noise level at waiting mode the “standby mode” is added.
       There are additional slots for headphones or an external amplifier and a microphone;
       In order to extend the dynamic range in the return channel the device has a compressor;
       Connection line failure diagnostic and output signal level indicator are provided.
