Please check out our other church technology videos available at academyav.com In this video we are going to look at an overview of an equalizer. EQing is the process of changing a specific frequency in the audio spectrum of the signal. There are two basic types of EQs, graphic and parametric. The parametric EQ is more common so we will focus on that. The first parameter to adjust is the frequency. The frequency control is used to sweep through the spectrum so that you can find the specific frequency you want to manipulate. The second parameter that's adjusted is the gain. The gain is used to boost or cut the selected frequency. This will change the overall sound of the selected signal.  The third parameter is the Q, also known as the bandwidth. The Q is used to adjust how wide or narrow the frequency range is. Think of a wide Q as a slow gradual hill and a narrow Q as a tall steep mountain, with the frequency selection being the center peak. The three parameters that we just discussed make up what we call an EQ band or filter. Many consoles have four EQ bands that you can make adjustments to. Those are the low, low-mid, high-mid, and high frequencies. Another option that most consoles have is a shelf filter. A shelf filter allows you to select a specific frequency and then cut or boost all frequencies above or below the selection. Shelves are available on the high or low end of the spectrum. One final feature of an EQ is a highpass and lowpass filter. The highpass filter is used to block all frequencies below the set frequency, and the lowpass filter is used to block all frequencies above the set frequency. Using these parameters, the EQ is able to adjust the frequencies of the audio signal.Thanks for joining me today. Please check out our other church technology resources available at academyav.com
