Talking about Power: What is Peak Power and RMS?

When comparing 5 channel amplifiers and speakers, one of the most significant criteria is the power rating.

Power is the rate per unit time in which energy is transferred. The standard unit for power is Watt. You can determine the wattage of an amplifier based on what is indicated on the product’s description. There are several ways to express power. It is expressed as either Peak Power or RMS.

Peak power and RMS are different. As you browse a channel amplifier, you will notice that certain product shows peak power whereas others indicate the RMS of the item. So, what is the difference between these two?

What is Peak Power?

If this is your first time to buy a channel amplifier, you might think that an amplifier with a high peak power is a worthy investment. Mind you, do not focus your attention on the item’s peak power.

The Peak or maximum power does not measure the continuous power of an amplifier. It refers to the maximum power level a speaker can utilize in short bursts. Suppose to say, you get a channel amplifier with an RMS of 250Watts and has a max power of 500W. It entails that the item can ruin in 250W but occasionally utilize bursts of power that may reach to 500W.

You have to be observant and careful when buying 5 channel amplifiers. There are some manufacturers which assign random power output just to appear impressive to the eyes of buyers. First-time buyers are usually the victims of the over-inflated power output, which is one of the common mistakes when buying amplifiers.

What is RMS?

The RMS (root mean square) power refers to the continuous power a speaker can utilize for a prolonged period of time. It is the statistical measurement of the magnitude of varying quantity applied to voltage. Therefore, when comparing speakers or amplifiers, what you need to look into is the RMS power and not the peak power.

However, you must know that each manufacturer has a different way of calculating RMS power. Thus, you could not always guarantee the accuracy of a 5 channel amplifier. Then, how can you assure that the 5 channel amplifier you plan to buy provides accurate measurement of continuous power?

Look for the CEA certification of the product and read a pretty fair review from reliable sources such as the Sound Certified.

Beginner’s Guide: How to Choose Your First Keyboard

Never touched a piano keyboard your entire life but you are starting to take interest in playing one?

If you are, you should know that learning how to play the piano would be very challenging; however, it is going to be fun if you have the right piano keyboard designed for the beginners.

To help you choose your first keyboard, here are some helpful tips created for beginners like you:

1. Learn the features of the piano

When selecting a keyboard you have to know its basic features;

•    The weighted key action – This is designed to supply more resistance, which allows you to experience playing with a true piano.
•    Must have at least 61 keys – The regular acoustic piano contains 88 keys, that’s more than 7 octaves. For a beginner like you, you should choose your first keyboard with 61 keys, that’s 5 octaves the least; anyway, as a starter, you’ll only be playing one to three octaves, which you may expand as you become familiar with every key.

However, you need to watch out for some extra features that can be distracting and confusing for beginners like you, especially for young beginners.

3. Your keyboard should feature drum rhythms or metronome

A metronome is a practice device that allows you to play in rhythms accurately due to its steady pulse or beat that it produces. As a beginner, it would be wise to choose a keyboard with this feature; this will develop your solid playing rhythm.

4. Choose a keyboard with fewer but relevant features

Learning how to work with your hands when playing the piano is already overwhelming. It may double if you choose a piano keyboard with a lot of extra features. Purchase a keyboard you think is simple, but with relevant features.
