These faders make it possible to balance channels during recording. An aurally compensated twin fader makes it possible to balance playback volume levels, too. These features permit recordings of every kind, such as Multi-playback, or sound-on sound; that is, rerecording from one track to another whilst making another recording on the other track.

Synchro-playback – this feature consists of synchronising two recordings on separate tracks which you do wish to mix by recording, and may be used for language laboratory purposes and for automatic control of lantern slides. Echo – adding echo to both mono and stereo recordings. The amplifier equipment is an outstanding new system consisting of no less than seven fully transistorised easily replaceable amplifier units.

Monitoring: separate records and playback heads with individual amplifiers permit both before-the-tape and off-the-tape monitoring. Power output is 2 x 8 watts undistorted.

Frequency response: 7.5″/sec 30-20 000 Hz (+/- 2 dB: 40 – 16 000Hz), 3.75″/sec 30 – 16 000 Hz (+/- 2dB: 40 – 12 000Hz), 1.7/8″: 50 – 8 000Hz (+/- 2 dB: 50 – 6 000Hz)

Recording level is indicated by two illuminated V.U. meters which indicate the sum of signals in each of the two tracks that can be recorded simultaneously.

Slack absorbers: Two smooth-running specially engineered slack absorbers take up slack, ensuring absolutely smooth starting and stopping at all tape speeds.

Electronic protection circuit prevents damage due to electrical overloads. No other tape recorder in this price bracket has these professional standards for electrical and mechanical specifications. Fine low-noise tape drive motor mounted on rugged non-torsion steel chassis. Four tape heads, 4-track recording but – a remarkable feature – the instrument plays back both 2-track and 4-track tapes.

The erase head (long-life dual-gap ferrite erases “right to the bottom” (70dB). The 2000 de Luxe permits recording from one tape recorder to another, parallel recording on a number of tape recorders, and simultaneous copying of both tracks. The Beocord may also be used as: public address system, permanently installed hi-fi control centre, and orchestra and guitar amplifier.” – taken from the 1967 – 1968 Bang & Olufsen product catalogue .
