Cartridge Tonearm compatibility
If you put in the information, this calculation chart will show you what the resonance frequency will be for the arm and cartridge. Between 8 and 14 hz should be fine! http://www.mh-audio.nl/Calculators/RF.html |
Would the Dynavector XX2MKII be a good match for the Jelco SA750E. The tonearm mass is 13.26gr. The cartridge weight is 8.9 gr and the cartridge compliance is 10 mm/N. This is a compliance at 100Hz You need a compliance at 10Hz or all your calculations will be wrong. To convert 100Hz to 10Hz you have to multiply on 1.7 So the actual dynamic compliance of your Dynavector is 17 cu ! Use 17cu when you calculate tonearm/cartridge resonance. |
Can you believe, I built this turntable and never once considered any of that technical mumbo jumbo? https://systems.audiogon.com/systems/8367 |
The resonance frequency is about 8hz. That should be fine!! Here ya go! https://www.ortofon.com/support/support-hifi/resonance-frequency |
This makes it easy if you have the arm effective mass and the cartridge compliance at 10Hz https://www.vinylengine.com/cartridge_resonance_evaluator.phpIf you only have compliance at 100Hx multiplty that by 1.7 and you'll be close enough or halve static compliance if that's what you know. |
Gary, you can read this thread first, maybe you don’t have to worry about. Jelco is a mid mass arm and Dyna is a mid compliance (17cu @ 10Hz) cartridge. It should be fine! In my opinion online calculation is always wrong, you can do that with Hi-Fi Test LP |
