Reviews

  • Very good mechanics
  • Audio 2/1989: Test winner 80 points = top class "4 ears".


  • Clean separation between analogue board of the signal part and the drive control by horizontally divided double housing
  • GX-75 had sometimes synchronisation problems between right and left, GX-75 Mk II not anymore
  • CD-Direct input for higher level from CD players, therefore extremely clean sound without level reduction
  • No remote control as standard (GX-95 supplied as standard)
  • GX-75 without extra pressure plate in cassette compartment (against cassette vibrations)
  • GX-75 MKII with pressure plate in the cassette compartment
  • Play speed can be switched to 50% by pressing and holding the play button. Advantage: exact cutting of e.g. radio speakers by A-B marking, the offset of erasing, recording and playback head is automatically taken into account!
