Specifications for 4x Duplication *
Tape Speed30 ips (76 cm/s) (original tape speed: 7.5 ips)
Tape Speed Deviationmax. 0.1% (from start to end of reel)
Tape speed accuracy = ±0.1% (after duplication @7.5 ips)
Wow & Fluttermax. ±0.1% (after duplication, @7.5 ips)
EqualizationTime constant for low freq. = 795μs (equal to NAB-J eq of original tape speed)
Time constant for high freq. = 12.5μs
Frequency ResponseBTR-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 Ratiomin. 55 dB (@250 nWb/m, after duplication, 7.5 ips, UNWTD with BPF)
Start Timemax. 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).
