Tape Transport
Three Studer eddy current motors. Electronically governed capstan motor. Electronic speed change. Solenoid operated via 3 relays.
Tape Speeds:
3.75 and 7.5 ips (9,5 cm and 19 cm/sec.) ± 0.2%
High speed Version: 7.5 and 15 ips (19 cm and 38 cm/sec.) ± 0.2%
Wow and Flutter:
max. ± 0.04% at 15 ips
max. ± 0.08% at 7.5 ips
max. ± 0.1% at 3.75 ips (Weighted at DIN Standard 45507)
Tape Slip:
Less than 0.2%
Reel Diameter
Maximum 10.5" (26,5cm)
(Minimum hub diameter 23/8 inches)
Forward / Rewind
Fast winding time for 1800' (1100m) is 92 seconds
Tape Heads
Three (Separate precision erase, record and playback heads.) Patented 'True Radius' design ensures excellent S/N ratio and head wrap
Guide System:
The Heads, the capstan drive, and the machines tape guides are mounted to a one-piece casting to maintain precise alignment.
Operating position:
horizontal or vertical
Electrical
Monitoring
Individual stereo record and playback heads with separate preamps, plus separate record and play circuits permit full source-tape monitoring.
Equalization:
NAB Standard on both record and playback at all speeds.
IEC Standard switchable on playback only.
Record Playback
Frequency Response:
(Based on Revox 601)
15 ips - 30 Hz - 20 kHz ± 1.5 dB
7.5 ips - 30 Hz - 20 kHz + 2 / - 3 dB
3.75 ips - 30 Hz - 16 kHz + 2 / - 3 dB
Signal to noise:
2-Track:
15 ips - better than 66 dB
7.5 ips - better than 66 dB
3.75 ips - better than 63 dB
4-Track:
15 ips - better than 62 dB
7.5 ips - better than 62 dB
3.75 ips - better than 59 dB
Add 4 dB to the above figures with Dolby on, referenced to less than 2% THD
(Reference with Scotch 203 or Revox 601 or equivalent. Weighted as per CCITT C-curve to exclude supersonic bias noise.)
Distortion at full modulation
at 1 kHz:
Max. 2% at 15 ips and 7.5 ips.
Max 3% at 3.75 ips.
Crosstalk at 1 kHz:
Stereo, better than 45 dB
Mono, better than 60 dB
Bias frequency:
120 kHz, push-pull oscillator. Designed for low noise, high output tapes
