Specifications for 4x Duplication * |
| Tape Speed | 30 ips (76 cm/s) (original tape speed: 7.5 ips) |
| Tape Speed Deviation | max. 0.1% (from start to end of reel)
Tape speed accuracy = ±0.1% (after duplication @7.5 ips) |
| Wow & Flutter | max. ±0.1% (after duplication, @7.5 ips) |
| Equalization | Time constant for low freq. = 795μs (equal to NAB-J eq of original tape speed)
Time constant for high freq. = 12.5μs |
| Frequency Response | BTR-10J-2S = 20 Hz to 12 kHz ±2 dB (@7.5 ips, after duplication)
BTR-10J-FS = 20 Hz to 9 kHz ±2 dB (@7.5 ips, after duplication) |
| Signal-to-Noise Ratio | min. 55 dB (@250 nWb/m, after duplication, 7.5 ips, UNWTD with BPF) |
| Start Time | max. 0.4 s |
| * 4x Duplication: Using 30 ips tape speed, the BTR-10J can send/receive programs to/from a digital audio file (DAF) system at 4x normal play speed. Equalization for 30 ips is set for 4x duplication to get flat frequency response at the original tape speed (7.5 ips). |
