Revox Tape Recorders:

The Revox A77 Tape Recorder was the start for the most successful tape recorder series of the enterprise. The first sales folder was called with "tradition and progress" and presented not only a new tape recorder, but a rear-Fi-line, which included also an amplifier and a FM fM-Tuner. It permitted the experiences in the building of tape recorders since 1949 and the development to a completely new technology, which was based on the sturdy silicon Planor technology, to take completely new paths. Power amplifiers plug-in made the direct connection possible of two loudspeakers. The new development was accompanied by the German designer Manfred Meinzner, which ensured that the entire line received a praegnates appearance. The entire drive assembly of the A77 was developed on a sturdy, twisting-free pressure pouring chassis; to further stability were likewise clay/tone engine storage, clay/tone head carriers and even the side panels from pressure pouring. The A77 was to be operated without restrictions also vertically. It had naturally a 3-Motoren-Antrieb. The durable synchronous engine was a genuine pioneer achievement.

The Revox B77 The creative machine in 56 variants; The advantages of this matured professional technology benefit thus also the amateur. With the B77 possesses it a creative "studio", which does not leave desires open. THREE ENGINES. THREE CLAY/TONE HEADS. The B77 is equipped with a three-engine drive assembly with direktantrieb and servo control. Two engineengine engines bring the tape coils in shortest time on operating speed or brake them fast, precisely and sensitively. By technology of the regulated Capstan capstan-Tonmotors thought out in the detail even hardly wahmehmbare fluctuations in the speed become balanced. Thus the name became REVOX the synonym for synchronisation. Also with the precision clay/tone heads for admission and rendition, manufactured developed, by REVOX and, the principle of the function separation is kept. This made possible both to Hinterband control and variety of easily adjustable trick effects such as echo, resound, duo -, multi and Synchro synchro-Playback.

The Revox B710 of REVOX sets new yardsticks. Their genuine klangwiedergabe is not to be exceeded. Original-faithful admission and refined mixing technology inspire even the professional. For the reliability and longevity the name vouches REVOX. Owing to its technical superiority the B710 is incomparable and expels their owner as a connoisseur. REVOX fulfills its high requirement in terms of musical truth compromiseless. Four-engine drive assembly: REVOX dedicates special care to the substantial functions of the cassette device. Two directly propelling quartz-synchronized Capstan engines guarantee accurate synchronisation and tape feed without jerking. Two precision precision engineprecision engines provide for fast rewinding and grant a highest possible measure of volume indulgence. No other equipment seizes your cartridges so gently and surely to a life long. The assembly of the four engines on a twisting-free pressure pouring chassis, on whatever the three separated Sendust and ferrite clay/tone heads are attached, secures the stability of the drive assembly.

The Revox B750 amplifier amplifier clean in itself. The research found out: Transistor amplifiers have more trouble opposite high-quality tube amplifiers with "transient ones". Transiently is called volatilely, rapidly temporary - and transient ones occur in the music frequently: They lead to short, but complex impulse distortions, which are too fast around a tiny little thing, when they could be corrected by the inverse feedback. Result: The amplifier is briefly overridden; the phase shift in the correction leads within the range of high frequencies to short, substantial distortions. While the "recovery period" the modulation which can be transferred is suppressed. STUDER REVOX solved the problem of the TIM distortions (TIM or TID, transiently intermodulation Distortion) by complex measures: The output stage is full-complementary, symmetrical. Simply said: The positive and the negative side of the signal are symmetrically strengthened in separate transistors, from the entrance to the exit. The einzelstufen are approximately coupled in itself, so that only a small total inverse feedback is necessary.

With the Revox B760 Tuner Revox brought the FM fM-Tuner to the third generation on the market. It united the successful construction principles of the predecessor models A76 and A720 with large convenient operation and far improved receivings caracteristics.Augenfuelliges characteristic of the B760-Frontplatte was the field with 15 programmable transmitter keys. The display indicated the station frequency and the storage location. The dissolution of the crystal accurate tuning was doubled, the raster amounted to now 25 kHz or 840 steps in the UKW volume again. Thus the B760 was from the outset suitable also for "bent" transmitter frequencies and the arising cable systems with converters.Who wanted to test its receipt situation accurately exactly, an oscilloscope exit was available at the B760. On the screen were analyzable thereby signal strength, stroke.

The Revox B790 a crystal-controlled direct power unit with tangential short clay/tone arm, was introduced together with the rear-Fi-plant B77/B750/B760. All people were not inspired by the Design of the tiltable "cigar box", but capability characteristics of the new creation let aufhorchen. Here simply an existing conception was not improved, but in principle new solutions for old problems were found. The ultrakurze "LINATRACK" Tonarm was 4 cm long and weighed inclusive pick-up cell only 40 g. the clay/tone arm was opto-electronically steered, by means of servo-drive tangential still-led, exactly the same as a record also cut. Putting on was a children's game: Plate present, box pivot, key press. The clay/tone arm did not need an antiskating device, because from the tangential guidance no Skatingkraefte resulted and concomitantly no rattling/clinking distortions and no cross modulation (caused due to trace angle errors) arose.

Revox B215 Cassette Deck is a symbol for the harmony of matured mechanics and high-intelligent electronics. Singularly: The drive assembly with the four engines. The heart of the B215 is a drive assembly from substantial pressure pouring with four engines, which propel the two Capstanwellen and the two tape windings directly. On which one is proud rightfully with Revox: No other equipment treats the cartridges more carefully than the B215. The Sendust ferrite Tonkoepfe proves Revox level by its high quality and is characterised by outstanding long-term Konstanz. The large throw: Revox computer. The intelligence of the measuring computer in the B215 is singular. The thoroughness and effectiveness of the complex computer program place all past into the shade. In each kind of volume of each manufacturer the equipment measures automatically in. In a complex measuring procedure with eight measurements the parameters for levels, Entzerrung and bias are determined. For the input of individual cartridge data six storage locations are intended. The entire measuring procedure takes only scarcely 20 seconds. Of course with this procedure the characteristics are considered by Dolby b and C.
