Tandberg 3300X


The series 3300X is a new and outstanding tape deck suited for the world's most discriminating markets in respect of quality and sound reproduction fidelity.

The recorder is equipped with the revolutionary Tandberg crossfield which has extended the frequency range upwards and made the lower tape speeds more useful, the input dynamic range has been extended up to 66 dB, and simultaneously the input signal/noise level has been improved.

It has separate heads for recording and playback, rendering choice of A or B test monitoring and enabling sound on sound and echo recording. The high sensitivity microphone inputs are intended for dynamic microphones with 200 to 700 ohm impedance.

Separate inputs and outputs, located on the bottom cover, are provided for connection of receiver and amplifier.

A fast rise, slow-decay (peak reading) record level meter on each channel indicates the program level applied to the record head. Stereo headphones for monitoring can be connected to socket on the top plate.

The recorder features flying start from record to playback mode or vice versa. The series 3300X can be used in playback mode and as a microphone amplifier at the same time. This makes the recorder well suited as a central unit in a music and speech distributing system.

This deck plays and records extremely good, due to the cross-field technology. Major downside is the single motor design, which requires the mechanics to be well adjusted for the machine to perform it's best. Adjusting the mechanics can be a bit pain in the a**, but not impossible, it requires patience and reading the service manual available from this website thoroughly.

The deck *looks* nice but feels a bit cheap. It does rival high end decks in recording and playback quality, when properly aligned.

Good vu metres and solid made, downside is headwear, I have had two of these machines over the years and they both suffered bad headwear and loss of sound quality. Shame
