Tandberg 3500X

 Unsual facilities.

The 3500X has unsual facilities for record and playback. The Tape/Source buttons determine whether record monitoring will be a source (programme0 test or a tape test (A test or B test). The tape test is particularly useful because you can listen to tape that has just been recorded while the recording continues.

Tape recorder 3500X is suitable for every music installation.

A model in geat demand in the middle price bracket with a good performance and many attractive features. Suitable for all Hi-Fi music centers providing record/playback in stereo or mono with excellent sound quality. The 3500X is designed for connection to a good quality stereo amplifier such as the Selvsuper, the Huldra or the TR 220.

 The recording quality determines the sound quality.

The playback quality of a tape can never be better tahn the recording quality. A tape recorded on a poor tape recorder can never be improved even when it is played back on a god machine. Tandberg has always paid particular attention to this point when designing tape recorders. The Tandberg Crossfield technique was specially developed to raise the recording quality. The tape transport and the tape path have been designed to allow the tape to pass smoothly and precisely across the heads without undue strress and strain. The heads have been developed and manufactured by Tandberg to exploit the best features of the latest types of tape. Everything possible has been done to ensure that the recording quality is excellent.

Even though the 3500X is reasonably prieced it is fully equpped to play a central role in any Hi =Fi music centre.
