Revox A700


built from 1973
From 1973 Revox produced the A700, from which later the Studer B67 emerged.
With four belt compensation rollers, three belt speeds, quartz-matched speed control, and sinusoidal winding motors, the unit already has some of the features of Studer studio equipment.

tape speed

At 38 cm / sec, 19 cm / sec and 9.5 cm / sec. It allows you to play all your older tapes or create recordings for a wide variety of needs. This will enable you to save band-friendly voice recordings or high-quality master recordings.

wow and flutter

better than 0.06% at 38 cm / sec,
better than 0.08% at 19 cm / sec and
better than 0.1% at 9.5 cm / sec.

With our pressure rollers for the Revox A700 all values of the pitch fluctuations are undercut!

display

mechanical, 4-digit real-time display in seconds and minutes, but only at 19 cm / sec. At 9.5 cm / sec you must multiply the display by 2, at 38 cm / sec you must divide by 2.
electronic, 5-digit real-time display in hours, minutes and seconds.
At each of the three speeds, the elapsed tape length is displayed in hours, minutes and seconds. The counter readings are retained after the Revox A700 has been switched off.

dynamics

better than 65 dB at 38 cm / sec
better than 66 dB at 19 cm / sec
better than 63 dB at 9.5 cm / sec
These are all outstanding values that the Revox A700 delivers.

Why did this information always come from?

There is worse, if today with 1000 W PMPO advertised and the built-in transformer max. Give 10 W!

VU

Level indicator (analogue): VU-Meter ASA standard with optical peak value display
Overload indication: Threshold: 0VU 6dB (514 nWb / m), response time 10 ms, hold time 0.2 sec.
We offer an LED version as a replacement for the analogue VU meter. 20 LEDs per channel ensure a high resolution.
Overload indicator: Threshold: 0VU 6dB (514 nWb / m), hold time 0.5 sec.
The installation takes place without soldering and is hardly more expensive than a replacement of the analog VU meter, level indicator!
