Equalizer using errors
Equalizer full name is room equalizer. In audio system has a wide range of applications, but in most cases, it does not play. Are examples. First, the equalizer as tone controller before going to an organization to participate in an activity, for the occupation of sensitive, by the way to the sound control room, only to find audio Ark of equalizer 31-point potentiometer is neat settings into two high, middle, bottom of the shape, feel free to ask, tone control Member said that sounds nice, I cannot help but no answer. Coincidentally, there is also a sound system, the device is very high, all imports, but found the equalizer is the frequency potentiometer is a straight line, I want to be the ideal venue, its frequency response nor a straight! 2, the equalizer as feedback suppressor for a day, go to the system of inspection and found the equalizer of a few frequency point potentiometer faders at the bottom, he asked the construction unit of the technical staff, he told me that this is one of several produced Whistler's frequency attenuation, I put it to the maximum, the whistle will not be produced. I said it! you'll try again. So he took out a cylinder, the FM volume faders to push the result or have resulted in Whistler. He noncommittal. Third, the equalizer for sound system prerequisite configuration now, outdoor square activities more, increasing mobile sound reinforcement device, but I find that most of the system still configured the equalizer, and are in working condition, ask the person engaged tone control, are not true, anyway, with the distribution to use. These can be said to be a universal phenomenon, little equalizer with good on the effectiveness of the entire sound system to complement each other, while undermining the system's stability, balance. We know, an equalizer (especially room Equalizer). Its role is very targeted, speak clearly point is on the sound system and the frequency response of the venue I Chin to compensation, to reach in a relatively flat frequency response characteristics of sound reproduction, no other action, any expansion of its range of use is your own wishful thinking. Generally our common Equalizer mostly diagram type, 31. The so-called graphic type is its compensation potentiometer in the Panel position potentiometer faders, visually reflects the adjustable frequency and upgrading or attenuation values, their compensation curve is where the curve potentiometer faders. That's why as a 31-point? studied vocal or have some acoustic Foundation people know the octave, the lower octaves, its corresponding frequency is doubled, lower 1 times in order to comply with the requirements of the various voices of music, while allowing a more precise compensation. In 1 x frequency between 2 frequency, 20 ~ 20K audio range (in 1/3 octaves) out of a 31-point. Notwithstanding section 9 (1 octaves), 15 (2/3 octaves) are not widely used.
