What is Phono Cartridge Capacitance?
The first thing to understand about phono cartridges is that they have a certain capacitance. There are two main types of operational characteristics – mechanical and electrical. The electrical type can result in transients that ring or sound slack. Changing the capacitance of the phono cartridge can make the transient sound smoother, while mechanical resonance may result in muddy, slack transients.
The first type of capacitance is the one associated with phono cartridges. The other type is the one with a polarity that changes from hysteresis to resonant mode. This is the most important component of the phono cartridge. The second type is the passive type. This is made up of a plastic film that is placed over the moving magnet.
The second type of capacitance is the passive type. This type of cartridge has a capacitive capacitor, which is used to store and reflect sound. However, it is worth noting that a phono cartridge’s lifespan is based on several factors. It is better to store a phono cartridge properly and avoid putting it in direct sunlight, where it will be prone to absorbing heat.
The moving-coil type is difficult to make and is not widely used. Its incredibly linear properties make it an ideal choice for phono cartridges. Because it is incredibly low in mass, it is more difficult to manufacture. Thin wires are necessary for this, but the wires have a high degree of fragility. This is why moving-coil phono amps are not easy to adjust.
When a phono cartridge is used, the input capacitor is used to generate an electrical signal. The arm cable wiring and phono cartridge itself will also add some capacitance. Moreover, the phono preamp has a 47k resistor. This combination will result in a response graph that does not rise or peak. Instead, it will be flat or have a downslope that is double the initial slope.
The most recommended Denon DL-110 review capacitance is often in the range of 100 – 200 pF and adjusting the load capacitance will affect the response time of the cartridge, such that the high frequencies may become more or less prominent along with other more subtle effects, and although the reactance between tonearm cable and cartridge coil inductance creates a spike in the frequency response, this does not create new energy as it only amplifies whatever is present in the local electrical environment. A decrease in frequency is the most suitable for a high compliance phono cartridge with a stiff phono cartridge overhang.
The other factor that affects the cartridge’s performance is its load. In order to achieve the highest impedance, it must have an input capacitance of five times or more of the primary load. When it has a high load, this means the cartridge is conductive and is therefore conductive. A low loading will lead to low resistance. But it will still have an output capacitance of one turn, which means that the cartridge is loaded in the same way as the primary.
The total load impedance of a cartridge affects its output. For a MM cartridge, the load impedance is five to ten times the total load impedance. The MM cartridges’ total load capacitance is approximately seventy-two kHz. In general, a low load capacitance is not good. A higher loading would be more beneficial.
