The new tape recorder Series 6000X is designed for the world's most discriminating markets, and is in a class by itself when it comes to quality, precision and sound reproduction. Tandberg Series 6000X Stereo has a modern design. The operational devices are clearly arranged and in spite of its numerous technicalities the tape recorder is simple and easy to operate.
Series 6000X Stereo is a fully transistorized stereo recorder with 3 speeds: 7-1/2, 3-3/4 and 1-7/8 ips. It is intended for use together with separate hi-fi amplifiers and has therefore no built-in power amplifiers. There are separate heads for recording, playback and erase, plus a bias head. Two moving coil meters indicate recording levels. These instruments also indicate the output level at playback.
The recording is based upon the Tandberg Cross-Field technique, giving sensationally good specifications for frequency range and Signal-to-Noise Ratio. Inputs for dynamic microphone, line, radio, magnetic and ceramic pick-up. Limiter prevents excessive input signal levels during recording. Listening during fast wind and rewind if desired, makes it easy to locate a programme on the tape.
Professional tape recorder users will appraise the merits of Series 6000X Stereo. Mixing possibilities in stereo with separate input controls (2 for each channel), microphone with pick-up, line or radio. 4 input controls for mixing in mono. AB-test, - that is you can listen to a programme during recording (monitoring). And you can also listen to the playback during recording. Possibilities for "Sound-on-Sound" copying of a programme from one track to the other, and mixing in a new programme synchronously with the first one. Possibilities for echo and other trick recordings.
Tandberg 6000X Stereo has one-lever control of tape drive, push-buttons for electrical functions and track selection, illuminated 4-digit revolution counter, automatic end-stop, pause=button and possibilities for remote control of start and stop.
Tandberg Series 6000X Stereo is available in 2- or4-track versions, in teak or rosewood cabinets.
Crossfield Technique
The technique employed by Tandberg introduces a separate bias head which thoroughly magnetizes and reduces the recording zone on the tape as well as wavelength dependability losses in the record function. In turn, the need for equalization in the record amplifier as well as distortion in the ultimate recording is reduced. Consequently, Signal-to-Noise Ratio, Dynamic Range and Record Frequency Response are all vastly improved. The fact that Tandberg designs and manufactures its own heads further crystallizes the ultimate potential of each Tandberg recorder into an optimum range. Therefore, it becomes evident why Tandberg's position as the world 's leading producer of tape recorders remains unmatched in the world today.
