SME IV.VI Tonearm And
I've just purchased SME IV.VI tonearm and Ortofon SPU Royal N Moving Coil cartridge (0.2 Volt output).
As step up device I use Music Reference RF-4. Till I get them delivered by mail I won't stop worring about their compatibility. I hope I didn't make a huge mistake by putting this combo together. I would appreciate if you take a quick look at the numbers to make sure if they would work just fine.
Thanks in advance!
Cartridge balance range: 5-16 g
Vertical tracking force: 0-3 g
Lenght: 12 cm
Resistance: 0.145 Ohm/conductor
Resistance: 0.535 Ohm/conductor
Output voltage at 1000 Hz, 5cm/sec. 200 µV
Tracking ability at 315Hz at recommended tracking force 70 µm
Internal impedance, DC resistance 6 Ohm
Recommended load impedance > 100 Ohm
Cartridge weight 12,8 g
Music Reference RF-4 Pre PreAmplifier (Step up):
Maximum Output Voltage: 20V r.m.s. into 50 K load
Output Impedance: 1.5K with 30 dB gain module
less than 5K with other gain modules
Input Impedance: 1 Ohm to 1 Meg, User Selectable
Bandwidth: (itno 47K, 20 pF load) .72 to 700Khz ( -3dB points)
Distortion .01% @ 100 mV output level, 10 Hz - 100khz
If I just would know what those numbers mean.
That is probably one of the main reason why "non-scientists" don't get high end audio - too scarry! =)
