When a person wants to buy a sound system, he or she needs to buy the correct amplifier accordingly. It is always preferred by a person to buy an amplifier that has the latest features at a minimal cost.
There are multiple kinds of Amplifiers available in the market today, ranging from different features to various costs in many brands, and two such types are the RMS and PMPO.
Key Takeaways
- RMS (Root Mean Square) is the continuous power output that a device can deliver without distortion. At the same time, PMPO (Peak Music Power Output) is the maximum power output a device can provide for short periods.
- RMS is a more accurate measure of a device’s power output, while PMPO is a marketing gimmick used by manufacturers to exaggerate the power output of their devices.
- RMS is measured in watts, while PMPO is an arbitrary measurement that cannot be compared across different devices.
RMS vs PMPO
The continuous power a device supplies without interruption is called RMS (Root Mean Square). RMS provides an accurate measurement of power output. The maximum power that a device can deliver for a short interval of time is called PMPO (Peak Music Power Output). The quality of sound can be measured through PMPO.
RMS is the short form for the root square. This is a measurement that is used for measuring the value of output in various kinds of power outputs. This type of measurement is stated to be the most accurate way for how a person can measure an output supple in power output.
PMPO is the short form of Peak music power output. A person uses this for measuring and analyzing the quality of sound that is produced by an amplifier.
The actual definition of a PMPO is not yet mentioned or defined anywhere, but it is the total of all the amplifiers a sound system uses.
Comparison Table
| Parameters of Comparison | RMS | PMPO |
|---|---|---|
| Full form | The full form of RMS is the root mean square. | The full form of PMPO is peak music power output. |
| Basic function | It helps to calculate the power of output in an amplifier. | It helps to advertise the power supply. |
| Characteristic | This provides real power to the amplifier’s power output. | This provides the highest velocity of power in an amplifier. |
| What they denote | They denote the ratio of the average power of an amplifier. | They denote the use of the amount of power used in an amplifier. |
| Work | It is supposed to be better at working as compared to the PMPO. | It is supposed to be less efficient in terms of working as compared to RMS. |
What is RMS?
RMS is the short form for the mean root square. This is a measurement that is used for measuring the value of output in various kinds of power outputs. This type of measurement is stated to be the most accurate way for how a person can measure an output supple in power output.
The other name for RMS is also called quadratic mean. When it is meant like this, it is used only to measure the sound system’s power. The RMS works in a process in which it is made to be connected with efficient electricity to an electronic amplifier.
This is the only way that is used to measure the mean output power of an amplifier. This is found to be used highly for more high voltage-producing sound systems in an amplifier.
Due to its high efficiency, the RMS has sometimes used even the peak values of an amplifier, including even the output value of a signal.
What is PMPO?
PMPO is the short form of Peak music power output. A person uses this for measuring and analyzing the quality of sound that is produced by an amplifier.
The actual definition of a PMPO is not yet mentioned or defined anywhere, but it is the total of all the amplifiers a sound system uses.
Because there is no certified definition of PMPO, the definition keeps changing, and to some, the overall definition is that it denotes the ratio of the continuous power of output. The best estimate of a PMPO can be taken by having a vise look at the sound waves produced in an amplifier.
The full form of PMPO should not be confused with peak monetary power output as they have the same short forms. There should be a difference maintained.
The use of PMPO can be used only for a specific period for it to sustain. This takes place without containing or causing any serious problems or damage to the amplifier.
Main Differences Between RMS and PMPO
- The full form of RMS is the mean root square, and on the other hand, the full form of PMPO is peak music power output.
- The RMS is used for denoting the calculation of the output value in power output; on the other hand, the PMPO is used for advertising widely.
- The RMS gives the real power to power output in an amplifier, and on the other hand, in a PMPO, it gives the maximum high voltage power to power output in an amplifier.
- The watts of an RMS denote the ratio of the average power of an amplifier when it is riding on a sine, and on the other hand, the watts of a PMPO denote the use of an amount of voltage in an amplifier.
- The RMS is said to be better at work compared to the PMPO, and on the other hand, the PMPO is said to be a narrow concept compared to the RMS.
