Commentary

This tape recorder was announced as a successor to the X 1800 sd.
In addition to open-reel and 8-track cartridge recording / rerecording, cassette tape recording / rerecording is possible.

The open-reel section uses a cross-field head to enable wide-band recording, and uses a two lever system for reliable operation.

The 8-track cartridge has a channel selector button for easy program selection.
Recording from open-reel is also possible.

The cassette section allows recording from open-reel.

Equipped with 3 auto mechanism mechanisms, automatic shut-off of open-reel, automatic stop of cartridge (set of start position) and automatic stop of cassette are possible.

The recording and reproducing head uses a 1-micron permalloy shield head, and the motor uses a directional silicon steel shield to improve the S / N ratio.
In addition, the cross-field method is adopted for the open-reel section. By applying the signal current from the recording head and the bias current from the external bias head, the signal recorded on the tape can be recorded without being affected by the bias magnetic field.

Distortion is reduced by using four ICs for both channels, one IC for each of the preamplifier and main amplifier.
The recording bias frequency is 81 kHz.
