What is a high current amplifier?
Like all amplifiers, a high -average amplifier takes a sound signal and increases its size and strength. The unique capability of high current amplifier comes in the type of energy it provides. While all amplifiers have power that is a combination of amperage and voltage, high current amplifiers can generate high amperage. This allows them to drive more demanding speakers and also manage multiple speakers at the same time. The signal that the amplifier adds, usually expressed in watts, consists of a combination of voltage and current. The voltage measures how large the "pressure" has the power flow at the current measures how many electrons actually flow over the wire in a given period of time. The power consumption is calculated by multiplying the voltage by current. For example, while a low -average amplifier can generate 100 watts by sending 4 current amplifiers down to the Na25 volt conductor, a high current amplifier would send 16 amperes of current at 6.25 volts. Impedance usually measures in ohms, measures how much speaker resistant the signal that issent to him. Lower impedance speakers require a higher current power supply, while speakers with higher impedance demand relatively smaller current and relatively larger voltage. The audio system with low impedance speakers will usually benefit from a high -frequency amplifier.
low impedance usually occur in two situations. The first is in top speakers, many of which, such as large electrostatic belt speakers, are designed specifically with low impedance. This also happens when many speakers connect to one amplifier. Two speakers with 8-ohm impedance, which is the norm for the disadvantage of the UMER-class electronics, connected in the series, will introduce a 4-ohm impedance amplifiers. Connecting multiple speakers to one amplifier is also a frequent occurrence in public address systems (PA).
Generally speaking, low -transparent amplifiers are smaller, lighterAnd cheaper. High current amplifiers will usually be larger and heavier and more expensive. However, in exchange for additional costs and volumes, they provide better power at low impedance loads. They can also use their extra current capacity to supply more energy to medium and high impedance to better reproduce the peaks of the volume in music and other material.
