Jump Straight to Calculator The calculator below is useful in determining the total impedance of speakers in series. This calculator for amplifier power, voltage and current has little significance but is rather interesting.
In the specifications for an amplifier, it might say This distributed speaker system SPL calculator takes the guess work out of which speaker tap to use.
It will tell you the correct power Jump Straight to Calculator This calculator will help you determine the cable losses in distributed speaker systems also known as volt or volt speaker systems Calculators Decibel Calculator for Audio voltage. If you don't like formulas then you definitely won't like the formula for calculating voltage ratios expressed in decibels.
So, use the following calculators to Here is a simple calculator for power, current, voltage and resistance actually there are 6 different calculators, use the one relevant to the values Calculators Power Usage Calculator. Knowing the cost of running an electrical appliance is useful, and easy with this power usage calculator.
You need to know three things: 1. Cost of These calculators will find how loud an amplifier and speaker combination will be, or what size amplifier you need to make a speaker a Calculators Lighting Costs Comparision Calculator. Energy efficient LED lamps for lighting are very popular. They certainly cost less to run than conventional lamps. But how much do you really Calculators Speaker Dispersion Calculator.
If you look at the specifications of speaker boxes, you should see something like Dispersion H x V : 90 x This is stating How much do you need to increase the gain of an amplifier to make it sound twice as loud: 3dB, 6db or 10 dB? Most countries have a stated maximum continuous noise level over a continuous 8 hour period a working day.
This is normally agreed to being Fundamentals Using a Multimeter. This article introduces the basic concepts of multimeters and explains how to use them for basic measurements. Multimeters are one of the most useful Fundamentals AC and DC. This article looks at some basic concepts and misconceptions of AC and DC electrical circuits.
There are no formulas involved, just explanations to some Fundamentals The Dreaded Ohms Law. In a previous article we looked at the power formula, and discussed the relationship between power, voltage and current. Having looked at the power Fundamentals What is Electrical Power? What is electrical power? What is the formula for electrical power? What is watts, volts and amps? This article introduces and illustrates these electrical Geoff reviews the Audioflow smart speaker switch which can be controlled through your smartphone or Alexa as they are Wi-Fi enabled.

When you see it on a TV screen the image will appear less-defined and with poor color accuracy, compared to the various flavors of component video that you can get.
A component video signal is clearer as it separates the color signals. Which allows for a better picture. Search for: Search Button. Paul started the Home Cinema Guide to help less-experienced users get the most out of today's audio-visual technology. He has worked as a sound, lighting and audio-visual engineer for around 20 years. At home, he has spent more time than is probably healthy installing, configuring, testing, de-rigging, fixing, tweaking, re-installing again and sometimes using various pieces of hi-fi and home cinema equipment.
I link to products I like. Pin Me! This is known as YPbPr component video. Component and composite audio-visual connection cables both transmit video via an analog signal.
Old-style composite cables are no longer supported by most devices. The newer component cable format was designed to work with modern high-definition devices. However, even component cables have had their day — high-resolution HDMI is now typically the connection of choice for the latest generation of audio-visual equipment. Because the video signal is forced to travel through a single cable it is heavily compressed, losing much of its resolution and picture clarity.
The cables also suffer from radio frequency interference, which further degrades picture quality. When given the option, go for component over composite every time because this connection will always provide a better picture at higher resolutions.
The only practical use for composite video today is when using older equipment, such as older video game systems or VCRs, which do not support the component video format. Because of this, some new HDTVs include at least one composite video input to make them compatible with old equipment.
Component video splits the video signals into three cables — green, blue and red — with each transmitting a specific component of the video signal. The green cable also called Y transmits the brightness information of the signal.
Green components are inferred by a combination of all three signals. Since component video is spread across three separate cables, it does not need to be as compressed as composite video, allowing support for HD resolutions as high as , as well as progressive scan images that create smoother images with more defined edges.
Component cables initially replaced composite as the de facto analog video cable, thanks to its improved picture quality and HD support. Nearly all HDTVs made today have at least one set of component inputs.
