1. What is RMS to PMPO Conversion?

Definition: This calculator converts continuous RMS (Root Mean Square) power to PMPO (Peak Music Power Output), a marketing specification for audio equipment.

Purpose: Helps compare amplifier power ratings and understand manufacturer specifications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ PMPO = P_{rms} \times k \]

Where:

Explanation: PMPO represents very short-term peak power handling, while RMS indicates continuous power output.

3. Importance of RMS vs PMPO

Details: RMS power is a more reliable indicator of amplifier performance, while PMPO is often used for marketing purposes with less strict measurement standards.

4. Using the Calculator

Tips: Enter the RMS power in watts and manufacturer factor (default 15). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is PMPO higher than RMS?
A: PMPO measures very short peaks (milliseconds) while RMS measures continuous power, so manufacturers multiply RMS by a factor (10-20x) to get PMPO.

Q2: What's a typical manufacturer factor?
A: Most manufacturers use factors between 10-20, with 15 being a common average value.

Q3: Which is more important - RMS or PMPO?
A: RMS power is more meaningful for actual performance, while PMPO is more of a marketing specification.

Q4: How do I find the RMS power of my amplifier?
A: Check the technical specifications (not marketing materials) or measure with an oscilloscope and multimeter.

Q5: Is PMPO standardized?
A: No, PMPO measurement methods vary between manufacturers, making direct comparisons difficult.
