Description

This ‘little brother’ to the quadraphonic QD-5500S had a similar specification but, while stereo record and playback was no problem, only quadraphonic playback was possible.
Features included a 4-channel playback head, stereo record and erase heads, auto-reverse playback (stereo) and a three-motor transport design utilising a belt to link the capstan motor to the capstan/flywheel. All transport controls were of the solenoid-touch type and two tape speeds (7½ and 3¾ ips) were provided. Maximum reel size was 7″.
