Reviews[edit]
- 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!
