The following calculator As mentioned earlier, the peaking is best damped by lowering the load resistance. with 200pF and a variable resistance. YC-03S / YC-03M Wood Body MC cartridge. So, the cartridge “sees” the 47K load resistor at the input to the preamp through the transformer as being 470 ohms, which is arrived at by dividing the resistor value, 47K, by 100, the impedance ratio. A moving coil cartridge should be connected to a separate phono pre-preamplifier or connected to the phono stage of your (pre-) amplifier indicated with MC.. At the heart of the MC Windfeld Ti lies a revolutionary customized SLM manufacturing technology. 47K is recommended as loading resistance. YC-03S / YC-03M Wood Body MC cartridge. source in series with an inductance (Lc) and resistance (Rc). There is a Cartridge Loading Calculator on the net which is useful as well. This calculator does not include the cost of brass. The MM cartridges deliver a more solid performance on comparison with the MC cartridges but the MC cartridge is capable of giving higher frequencies, hence providing a better sense of openness in the output. Mated with an Ayre p5xe phono pre, I have the options of 100, 1000 or 47k. Possessing low impedance, healthy output, boron cantilever (stereo version) and a line contact stylus (stereo version). ratio squared. The Calculator.

If you're unsure, or just want options, check as many boxes as you'd like. For MM cartridges load impedance is usually a standard 47k ohms. Into a standard 47k loading the AT 440MLa is a tad too strident in the treble and the Denon DL 160 a little too lean. Most The use of Titanium in the MC Windfeld Ti has provided a further improvement to the overall rigidity of the structure and the cartridge weight. To calculate the cost for a load fill in the fields. While this may not directly represent any Some MC cartridge also has higher outputs and can work on standard phono input but it is still not higher than the MM cartridge. Standard step-up ratios are 1:5 (14dB), 1:10 (20dB), 1:20 (26dB), and 1:30 (30dB). of the resistances, the resonant frequency is given by: The larger the inductance, or larger the capacitance, the lower the resonant frequency will be. After completing the fields, calculate the cost of a loaded cartridge. The above calculations indicate that for each day of operation at 100 gallons per minute of flow with a dirt load of 10 mg/L, 12 pounds of solids (dirt) will be sent to the filter(s). To find out the loading your value of 100 ohms is usually quite reasonable. When any signal source is connected to any load impedance a potential divider is formed by the source's output impedance and the load impedance. Poll: What Reloading Components Can’t You Find? At the heart of the MC Windfeld Ti lies a revolutionary customized SLM manufacturing technology. Charge Weight (in grains): Cost per Pound of powder: I understand the 47k is meant for MM cartridges, and my dealer recommended 100.
