the B77 is the industry standard...

Standard version of B77

Speed, 3.75 and 7.5 ips:

The REVOX B77 has been designed to satisfy the requirements of a vast number of applications.

ALL machines are constructed from the standard speed version, without major changes to the electronic or mechanical components.

The flexibility of the B77, and its mature technology are two of the main reasons why the REVOX B77 is frequently used by recording studios. Often side by side with the STUDER multi cannel studio tape machines.

The B77 features an extremely stable 3 motor tape transport system, which can be adapted easily to individual applications.

The neat arrangement of the control and audio electronics ensures excellent access to various test points and trimmer potentiometers for maintenance work, thus allowing field modifications to the machine for other applications.

ALL tape transport functions can be controlled remotely. A cable type remote control is available as an accessory. Of course, the tape speed can be varied by an internal control (mk 2 decks) allowing +/- 10% or via an external control across a wide range of 7 semitones.

Some of the simpler operations can also be performed by unskilled personnel because the controls are arranged for maximum operating convenience and reliability.

The logically interlocked tape command keys as well as the record pre-selecting facility (protects against unintentional erasure) also contribute to

high operating reliability. With its sophisticated transport and audio electronics the B77 is a flexible and efficient tape recorder with great application potential in recording, broadcasting, and film studios, as well as in industry.

The B77 standard speed version (3.75 and 7.5 ips (9.52 and 19.05 cm/s)) is available as a half track or quarter track machine with NAB equalization.

Depending on the application, either a rugged plastic housing with Nextel coating or a metal housing (for cabinet mounting) can be ordered.

High Speed version of B77

Speed, 7.5 and 15 ips:

The B77 HS is ideal for applications that require maximum frequency response, dynamic range, and treble response. Because of the high tape speed (7.5 and 15 ips (19.05 and 38.1 cm/s)), excellent frequency and treble response is achieved. Editing and splicing is also easier and more accurate with high tape speeds.

The B77 HS features the same sophisticated tape transport control as the standard speed model. The tape speed is doubled by increasing the capstan shaft diameter and slightly re-positioning the capstan motor.

The B77 HS can of course be operated with the same accessories as the standard speed model.

The high speed version is particularly suited for semiprofessional use or as a cost effective alterative to expensive studio machines in smaller recording studios or

local broadcasting stations. For this reason, the B77 HS is also available as a half track machine with either NAB or IEC equalization. The type of equalization to be selected depends on the equalization standard of the existing equipment or the library of recorded tapes being used.

The B77 HS can also be fitted with an additional sound head for control purposes.

Low Speed version of B77

Speed, 1.875 and 3.75 ips:

The B77 LS is designed for audio applications where uninterrupted playing times of over 6 hours is required and with excellent reproduction.

The B77 LS operates at two speeds: 1.875 and 3.75 ips (4.76 and 9.52 cm/s). The main distinctions to the B77 standard model are the smaller capstan diameter and a corresponding lower capstan motor speed. The B77 LS is available as a half track or quarter track machine. Because of its high recording and reproduction quality the B77 LS is ideal suited for audio applications in museums, exhibitions, galleries restaurants, or for speech recording during conferences.

Depending on the application, either the half track or quarter track machine can be selected. If only speech is to be recorded, the quarter track version is recommended because the recording time is twice as long. For recording and reproducing music, the quarter track version is less suited. It has equalization according to NAB standards.

The B77 LS is available in a Nextel coated plastic housing or in a metal housing (for cabinet mounting).
