Use it if you like the result. This one is a digital EQ. http://www.musiciansfriend.com/srs7/search/detail/base_pid/182493/src=01340 |

The first is a graphic eq which has fixed center points for the frequencies to be affected. This graphic eq also has a set amount of frequencies each slider affects on either side of this center frequency. How broadly each "band" of the eq affects is typically measured in octaves above and below the center point. All of the parameters are fixed by the design of the eq. The only option the user has is to boost or cut the level using the sliders. Because the center frequencies probably don't hit exactly at the problem frequencies of any one system, and the amount of frequencies affected is probably too broad or too narrow, a graphic eq tends to create more problems than it solves. It final affect when viewed across the frequency bandwidth is to create a "comb filter". The name refers to the spikes and dips in frequency response created by a graphic eq. The other type of eq is a parametric eq. This design allows the user to select from a varying center point and also select how broad the action of the eq will be. Adjusting a parametric eq can offer more help than the gross effects of a graphic eq because of its sophistication. Due to this sophistication, the cost of a parametric eq is usually much higher than that of a graphic eq. If a graphic eq and a parametric eq are priced similarly, either they are both very good at what they do or they are both junk. http://lp2cd.com/audio_terms/p/parametric_equalizer.html http://lp2cd.com/audio_terms/g/graphic_equalizer.html http://lp2cd.com/audio_terms/e/equalization.html for "comb filter": http://harada-sound.com/sound/handbook/defa-d.html |
