B77 MKI Tape Recorder

The Revox B77 tape recorder was presented at the 1977 audio trade shows together with a completely new hi-fi line.

This included the B750 amplifier and the B760 FM tuner, as well as the B790 record player and the BX series loudspeaker cabinets in the new design.

In addition to the standard version with speeds of 9.5/19 cm/s, the following models were available: B77-HS with 19/38 cm/s (high speed), B77-LS with 4.75/9.5 cm/s (low speed), B77-SLS with 2.38/4.75 cm/s (super low speed for monitoring tasks), B77-AUT0 with automatic recording start as well as three versions with additional pilot head for simple to sophisticated slide projector control. B77 synch tape recorders had a clock track amplifier for professional synchronous recording from the recording head. Finally, the B77-DOL offered separate Dolby TM-B processors for recording and playback (i.e. dolbysed back-band control) for the highest noise voltage ratios (19 cm/s, half track, better than 74 dB).

 

Value preservation for generations:  And even today, a B77 tape recorder can be integrated into the latest Revox Multiuser System, for example, and even controlled via Revox App.

Because sustainability is important to us.
