Misuse of equalizer
The full name of the equalizer is the room equalizer. It has a wide range of applications in audio systems, but in most occasions, it does not play its due role. Here is an example.
1. Using the equalizer as a tone controller A few days ago, I went to a unit to participate in an event. Out of occupational sensitivity, I went to the sound control room and found out that the potentiometer at the 31 frequency points of the equalizer in the audio cabinet was neat. The setting of the two ends is high and the shape of the middle bottom. Just ask, the sound controller said that the sound is good, I can't help but be dumbfounded. Coincidentally, there is also a sound system, the equipment is very high-grade, all imported goods, but found that the potentiometer of each frequency point of the equalizer is in a straight line, I think the ideal site, its frequency response will not be a straight line Right!
Second, treat the equalizer as a feedback suppressor
One day, I went to participate in the acceptance of the system and found that the potentiometer fader at a certain frequency point in the equalizer was at the bottom, and asked the technician of the construction unit. He told me that this was a frequency of howling. Point, I attenuate it to the maximum, and howling will not occur. I can't say it! You try again immediately. So he took out the flower tube and pushed up the FM volume fader, but there was still howling. He was undecided.
3. Use the equalizer as a necessary configuration of the sound system. Nowadays, there are many outdoor square activities, and mobile sound reinforcement equipment is increasing day by day. Most people do n’t say anything, just use it anyway. The above can be said to be a more common phenomenon. The good use of the small equalizer complements the effect of the entire audio system, otherwise the stability and balance of the system are destroyed. We know that an equalizer (particularly room equalizer). Its function is very targeted. To be clear, it is to compensate for the frequency response of the sound system and the venue where it is located, so that it can return to sound in a relatively flat frequency response characteristic. It has no other effect. Any expansion of its scope of use is your wishful thinking.
In general, most of our common equalizers are graphical, 31-segment. The so-called graphic type is the position of the compensation potentiometer on the panel. The height of the potentiometer fader intuitively reflects the adjusted frequency point and the rise or attenuation value. .
Why is it set to 31 frequency points? People who have studied vocal music or have a certain acoustic foundation know that the corresponding frequencies of high octave and low octave are increased by 1 time and reduced by 1 time. In order to meet the requirements of each part of the vocal sound, the compensation is more delicate. Two frequency points are inserted between 1 times the frequency, so 31 frequency points are divided in the 20-20K audio range (according to 1/3 octave). Although there are 9 bands (1 octave) and 15 bands (2/3 octave), they are not widely used.
Description of Right Angle D-SUB Connector
The right angle d-sub is an ideal connector solution for applications where space is at a premium and there is little to no room for connectivity & cabling. The 90° angle cable exit allows for increased mounting options and versatility of design for those tighter, more compact application needs such as computer servers and industrial robotics.
