Description

This was the first three-motor reel tape recorder from Tandberg, and after almost 20 years of the famous
‘joystick’ control, the 9000 series was also the first Tandberg with push-button tape transport functions.
Available in both half and quarter-track versions, the 9000X was a three speed recorder with a frequency response of 30Hz – 22kHz at 7½ ips.
Of course, all the electronics were totally solid-state. Four heads were used, the standard three for erase, record and playback plus a fourth crossfield bias head. Apart from Akai and their American clone Roberts, Tandberg was the only other tape recorder manufacturer to use the crossfield system.
The Series 9000 X was further developed to into the series 9100 X and series 9200 XD. The XD model had Dolby noise reduction.
