Understanding Audio Understanding Decibels part 2. In the first article we saw that a decibel is not a fixed unit, rather, it is a ratio between two levels. A decibel Understanding Audio Understanding Decibels part 1. Decibels are widely used in audio, and often misunderstood. These articles give a practical understanding on using decibels in audio work. But first, some Understanding Audio Understanding Audio Levels. A basic understanding of the general audio levels mentioned in this article will help you avoid the common mistakes often made when connecting audio Understanding Audio Understanding Microphone Sensitivity.
What do you understand about microphone sensitivity? Of late I have seen a number of people miss-interpret the specifications of microphones, especially when it After answering nearly questions on connecting speakers on this website, some common themes have emerged.
Please read the answers to these Frequently Asked Questions The speaker selector switch simulators presented here demonstrate how speaker selectors deal with speaker impedance and power distribution.
Speaker selector switches are used to In this article we look at how and when to connect 2 speakers in parallel or series. Both the theory and practical points on Speaker selector switches are the most common item bought from Amazon through this website with over units sold.
Therefore I thought it is Calculators Speakers in Parallel Calculator. Jump Straight to Calculator The calculator below is useful in determining the total impedance of speakers in parallel. It also calculates how the power is In an earlier article we looked at the issues involved in connecting multiple speakers to one amplifier. In this article we look at some I am often asked "How do I connect multiple speakers to my amplifier? You may still have many video tapes that you like to play but find it hard to connect a VCR to your new flat The recent passing of Eugene Polley, the man known for inventing the remote control, has given me cause to reflect on the development of It works similarly to a VCR, but This is the summary of the previous five articles looking at the different video signals and connectors commonly used in Home AV.
Previously we Connecting your TV is not as hard as it looks. All the sockets on the back and up the side of a flat screen This is the In this article, we look at component video signal: what it is, where it is used, and what cables are used for component video In this article we look at RGB video signal: what it is, where it is used, what cables to use and the problems with In this article we look at S-video signal: what it is, what cables to use, where S-video is used and the problems with it.
Do phone chargers and Ipod chargers draw power when not connected to their device? The answer is: it depends on the type of charger. In the popular press there have been a number of reports along the lines of "households wasting hundred of dollars on standby power". Being an inquisitive In this article, we look at composite video signal: what it is, what cables to use, where composite video is used and the problems Calculators Speakers in Series Calculator.
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.

Understanding Audio Levels Understanding Audio. RGB stands for "Red, Green, Blue" and is an analog component video standard for transferring video data. When you add HV to that, it refers to Horizontal and Vertical , and means that those two signals are each given their own wire. RGB offers better resolution and can carry more information than traditional RCA cables, but they can only carry video signals, so you'll need a separate cable for audio.
