      產品詳細介紹Product Introduction

      MSG-2174 is an FM multiplex signal generator adopted a multiple module method.
      Combination of DARC modulator, RDS modulator, and FM stereo modulator can be chosen depending on usage of user.
      DARC-VICS/RTIC FM multiplex method and RDS/RBDS FM multiplex method are available by this one unit, moreover a stereo modulator can be installed in same casing.
      By using application software attached to this unit, new data can be created and edited by a PC simply.
      This unit can output the data by being downloaded.
      Regarding DARC encoder function, we reduced its size by modifying specifications of MSG-2170/2173 and achieved cost reduction.
      As for RDS function, usability for production line was prioritized because it is an existing method.
