1978 Revox B77 right channel the figure was -67.5dB, other figures being better still. \ Whilst stability was very good, phase jitter was average but adequate, crosstalk was very good up to HF, but E\ HF measured 43dB at 15kHz. Wow and flutter measured better with the machine vertical, the figures being\ regarded as good, although 19cm/s measured better still on the low speed version. Speed accuracy was withi\ n 0.15% which is incredible, and spooling was fast for a LP NAB at 2m 12s, and neater than of old. I am very happy to recommend highly both low and high-speed models, alth\ ough it is a pity that each has only two speeds. All presets were set very accurately at the factory, an\ d both models checked were very reliable and much liked ergonomically. Note that variations in mains vol\ tage are accommodated, and 50 or 60Hz mains frequency alternatives present no problem since the motor spe\ ed is electronically controlled. Other variants include speed combinations of 2.4/4.8cm/s, 4.8/9.5cm/sec,\ professional balanced line in/out socket version, and a version incorporating loudspeaker amplifiers and i\ nternal speakers. Almost every version is available as rack mounting or portable. Three forms of slide \ sync having an extra head can be supplied, and a sel-sync model allows one channel to be brought up from \ the record head whilst the other channel is recording for adding a synchronised new track recording. file:///P|/9105%20werkdirectorie/Manufacturers,%20Manuals/Tapedeck/tests\ /9160CMREV-REV-B77-A1.htm (2 of 3)1-11-2003 11:16:59
