What is mix-minus?
This is a term used in the audio industry to describe a particular setup of a mixing console or matrix mixer, which eliminates the input from an audio device (such as a microphone or speaker) from the output to that device. That is, the output to the audio device contains everything except…
Like any type of technology the professional audio industry has its own vocabulary, one that can become a little confusing if you are not used to it. This Audio glossary from Extron is a great place to figure out the meaning of various terms used when referring to professional audio design and solutions.
Here are a…
As AV networks become more complex – because an increasing number of devices and rooms need to be a part of it – the use of matrix switchers becomes necessary. They allow the routing or switching of audio and video signals from multiple input sources to the one of several output devices.
For example; the video…

According to the HDMI Forum...
"HDMI (High-Definition Multimedia Interface) is a data transfer standard that allows high-resolution, all-digital data (both audio and video) to be transported via a single cable. This dramatically simplifies cabling and helps provide consumers with the highest-quality HD experience.
It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital…
LED’s open the way to new applications and markets in various different fields with a broad spectrum of requirements.
LED lighting has been revolutionary and perception of it as the leading commercially available lighting technology is transforming the lighting industry rapidly. One of its most important traits is its high reliability – whereby a lifetime of…
In a note titled “Measured light vs. perceived light”, Lutron describes the difference as follows…
“The human eye responds to low light levels by enlarging the pupil, allowing more light to enter the eye. This response results in a difference between measured and perceived light levels. A lamp that is dimmed to 10% of its maximum…
Colour temperature (or correlated colour temperature, CCT) is a number indicating the degree of yellowness or blueness of a white light source. Measured in kelvins (K), CCT represents the temperature an incandescent object (like a filament) must reach to mimic the colour of the lamp.
Yellowish-white (warm) sources, like incandescent lamps, have lower colour temperatures in…
One of the most attractive features of LED lights is the fact that their lifespan is much longer than of incandescent, fluorescent or HID lamp sources and that they are much less prone to failure. This leads to amazing energy savings over the long life of their use.
However, even high quality LED lights will experience…
