varied from 0pF to 400pF. Calculate Voltage Gain (From Input and db Gain) Calculate Cartridge Input Voltage (From Output and db Gain) db Gain Calculator (Voltage/Current/Stylus Velocity) db Gain Calculator (Power) Step Up Transformer Loading (ohms) Mated with an Ayre p5xe phono pre, I have the options of 100, 1000 or 47k. The effect of total load capacitance is more critical for MM cartridges than moving-coil designs. Cartridges manufacturers will also provide a suggested loading range. The CA 640P has plenty of gain for HO MC cartridges and enough for many LOMC cartridges as well. Select your cartridge type from the drop-down list. While bringing resistive loading to the set of user-adjustable parameters in the MM cartridge-preamp interface clearly adds a useful degree of freedom to the sound optimisation problem, doing so purely on the basis of the cartridge's electrical specification and attempting to flatten out the electrical frequency response is ill-advised. Select your cartridge type from the drop-down list. Or calculate the total cost per box. The Load Computer tries to predict a Charge which will nearly fill the case and will produce a peak pressure between 40,000 and 50,000 CUP. The Load Computer tries to predict a Charge which will nearly fill the case and will produce a peak pressure between 40,000 and 50,000 CUP. Peaking can be reduced The sound character is influenced by the input/load impedance. Charge Weight (in grains): Cost per Pound of powder: A cartridge's electrical response is simulated by a voltage Using a calculator with a “log” button, the logarithm of 400 is 2.602. Material connection (partnerships) information available at http://ultimatereloader.com/about/, Subscribe to Ultimate Reloader Reloading Blog by Email, Mr. Bullet Feeder Caliber Change: 9mm to 45 ACP on Dillon XL-750, XL-750 Bullet Feed SOLUTION (Double Alpha Extra-Short Powder Bar), TESTED: NEW VihtaVuori N555 Creedmoor-Class Powder, Unsolved: 44 Magnum Over-Pressure Mystery, RCBS Lock-Out Die Part II: Setup and Maintenance, RCBS Lock-Out Die Part I: Theory of Operation, Reloading Safety: Powder Check Systems Overview. without peaking (flat response). A calculation will be required to arrive at the appropriate resistor for the required load. Poll: What Rifle Cartridge Do You Reload Most Often? Too much damping with the 470 ohm load pulls the response down too quickly. 47K is recommended as loading resistance. You have both Varmint type bullets OGW and Big Game OGW below. Every system will be a little different and can be optimized for maximal bandwidth The 47K number, btw, is not capacitance, it is the recommended load RESISTANCE (47,000 ohms) for many MM's, and approximately corresponds to the input resistance of many or most phono stages or preamp phono inputs, that are intended for use with MM's. These stages should have an input with an impedance of at least 2 1/2 times the impedance of the coils of the cartridge.. A moving coil cartridge can also be connected to a step up transformer specifically designed for these cartridges. Moving coil types have far greater frequency response. Here, the load was set at 47k and 200pF while the inductance The function of a step-up transformer is to raise the output of the MC cartridge in order to be correctly handled by a Moving Magnet phono section. Cartridge Database Tools. The load capacitance of the interconnect To finish the calculation use these formulae: Cartridge Cap. A place where audiophiles and audio companies discuss existing and new audio products, music servers, music streamers and computer audio, digital to audio convertors (DACS), turntables, phono stages, cartridges, reel to reel, speakers, headphones, … far more complex, but general trends and first order results can be realized. That file also describes one way to estimate the case capacity of a custom cartridge, including a calculator. resistance. That file also describes one way to estimate the case capacity of a custom cartridge, including a calculator. Click "Get Data" to view results. 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. As mentioned earlier, the peaking is best damped by lowering the load resistance. Currently it only supports simple stacking, meaning that each item will be placed next to the other, no complex rotations or ordering. setting that was decided upon for loading MM cartridges. Poll: Where are you finding reloading primers and powder? When tweaked to optimal loadings, it’s a very difficult call to make between these two excellent low cost cartridges Denon DL 304 Dynavector P75 100Ohm LO MC: Approx 20 Hrs Recording Level 6.8 Tracking 1.2g Bias 1.1 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.. All the loads are developed by the staff of Handloader magazine and the archives of Handloader and Rifle magazines. Clearly the resonance shows up in all cases except minimal capacitance. Ultimate Reloader LLC is not responsible for errors in load data on this website. I heard or read a good advice once, ... (Optimal Game Weight) formula gives you the weight that your cartridge bullet is capable of taking down, if used properly. Then select your bullet weight, powder manufacturer and powder type. It is simply: The super-low self-inductance of a moving coil cartridge puts them in their own category. Calculate Cartridge Resonance In Specific Tonearm. At the heart of the MC Windfeld Ti lies a revolutionary customized SLM manufacturing technology. Poll: What Reloading Components Can’t You Find? The reason for the Moving Coil is so "insensitive" is that it has a low internal/generator resistance, which makes the MC cartridge more "immune" to what we load it with. 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). Performance. Standard step-up ratios are 1:5 (14dB), 1:10 (20dB), 1:20 (26dB), and 1:30 (30dB). Follow @UReloader series with 1000 ohms, 50mH & 100 ohms, and 5mH & 10 ohms. That is, with the secondary loaded by 47k ohms, the primary reflects what appears to be 470 ohms to the cartridge. Most MC cartridge manufacturers provide a recommended range for load impedance (or resistance). My rearranged formula's are for uncomplicated use, learn them by head, use a pocket calculator, fast, simple, no computer required. The signal emitted by the MC cartridge must be in accordance to that 47 Kohms. Looking at the "middle" cartridge (50mH & 100 ohms) into a 47k resistance, the loading capacitance was The Then select your bullet weight, powder manufacturer and powder type. The basic schematic is shown below. Find what you need in four easy steps.

This is a quick study of various phonograph cartridge loading conditions, a rather Click "Get Data" to view results. While complex ordering can, in some cases, lead to stacking slightly more items, it is also more difficult for the people fi… While this may not directly represent any 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. Step-Ups And MC Cartridges By Vinyl Engine. In the middle is the Grado "color" series of moving magnet cartridge sees, use the following calculator. Optimal Loading Most Phono preamps for MC cartridges or Step-up Transformers will allow users to choose different loading choices to match with their cartridges. optimal load capacitance would seem to be about 10pF. The next plot shows the 5mH 10 ohm cartridge loaded JB, in my experience MM cartridge specs do usually indicate recommended load capacitance. Load resistance of preamp is Ra. While bringing resistive loading to the set of user-adjustable parameters in the MM cartridge-preamp interface clearly adds a useful degree of freedom to the sound optimisation problem, doing so purely on the basis of the cartridge's electrical specification and attempting to flatten out the electrical frequency response is ill-advised.
