Problem Curve
: Here is a problem curve. The small variations in blue are OK. They are
2dB or less and you likely will never hear them. However, the variations in the red circles
are bad. While the ear is not so sensitive to dips in the response, it is very sensitive to peaks.
The response peaks are what makes a speaker sound "harsh" and cause "ear fatigue" (You
listen for a while then turn it off because it starts to irritate your ears). With this curve you
want to pull down those peaks to put them in line with the rest of the signal response.
Once that is done the system should sound just about right.
Continuous exposure to excessive sound pressure levels may cause permanent hearing loss. ZAPCO strongly advises that you use
common sense when setting volume levels. Everything written in this manual is for the proper use of the products. Some features
or specifications could be modified during production to improve the product performance. The technical specifications and
