Amplifier power is probably the most misunderstood and abused parameter of amplifiers and speakers. Yet, it is often the first and possibly only parameter Understanding Audio Understanding Speaker Sensitivity.
Speaker sensitivity is a measurement of how well a speaker converts the amplifier power to to acoustic energy. In others words, how loud the Often people are wanting to add speakers to their amplifier to increase power.
However, in most cases, adding speakers will reduce the power in Speaker impedance changes amplifier power output. In fact, your amplifier power could be nearly half or double its capacity - depending on the impedance Home Speakers Understanding Speaker Impedance. Speaker impedance is often presented as a complex subject and therefore is either ignored or misunderstood.
A basic understanding of speaker impedance is not Distributed speaker systems are also known as " volt line" or "70 volt line" speaker systems. They are used extensively where multiple speakers are Understanding Audio Double amplifier power does not double the volume. This article logically shows the relationship between amplifier power, SPL and loudness.
It includes a level difference exercise and a gain calculator. Understanding Audio Understanding Acoustic Feedback. Acoustic feedback it that annoying loud continuous tone you get when the sound system is not set up or operated properly. Acoustic feedback can Understanding Audio Understanding Audio Frequency.
Every sound we hear is at a certain frequency. When we say someone has a deep voice, we are describing a voice producing low 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.
Colored television, and computer monitors, borrowed this same idea of color receptors from our eyes. If you zoom into a computer screen, you'll see it's made up of tiny rectangles, or pixels. Each of which contain a red, green, and blue region. To display colors, the monitor illuminates these three colors accordingly. To make the screen appear yellow, the monitor turns on only the red and green regions in each pixel.
From far away, these blend into yellow. And that's how we can digitally create any color using just different amounts of red, green, and blue.
In our next exercise, you'll try to create a color by mixing together different amounts of red, green, and blue on your monitor. For example, to get this shade of green. It's interesting to note that other animals have different cones in their eyes. For example, dogs only have cones that are sensitive to yellow and blue, so red light doesn't send signals to their brain at all. The mantis shrimp, on the other hand, holds the current record for the most number of color receptors in its eyes, 12 different kinds.
And scientists still don't know how they're all used to perceive color.
