When you’re adjusting levels in a band, this is the exact frequency that is manipulated. They also let you tweak the primary frequency and the bandwidth as well, both of which I’ll explain right now.Ī primary frequency is a frequency that sits right in the center, between the upper and lower cutoffs of a certain frequency band. Parametric equalizers allow you to manipulate more than just the levels of each frequency band. If you to try to push up one point in the string, it’ll create a slope where a tiny bit of length on either side of the peak is also pushed upwards. It’s easy to understand if you picture the entire EQ curve as a straightened piece of string placed on a flat surface. One important thing to note with graphics EQs is that when you manipulate one slider, it’ll also have a slight effect on the neighboring bands, with the closest ones being affected the most. Usually, this includes bands that are in between the aforementioned once, which means you get even greater control of the entire frequency spectrum. Likewise, a ten-band EQ will give you control of ten fixed frequencies. This includes sub-bass (30 Hz), mid-bass (100 Hz), midrange (1000 Hz), upper midrange (10,000 Hz) and treble (20,000 Hz).
The number of bands and therefore sliders present in the EQ can vary, depending on the make and model.įor instance, five-band EQs will have five sliders, each responsible for manipulating a fixed frequency. These sliders allow you to either cut down that particular frequency or boost it in the mix. Graphic equalizers are quite simple, often featuring one control or slider for each frequency band present. There are a few important factors to consider which we’ll take a look at now: The TypeĬar equalizers come in two main types: graphic and parametric.

Choosing The Right Car Equalizerīefore we get to the full reviews, I want to talk a bit about how you would go around picking the right equalizer. This meant that I could go years without having to worry about corroded terminals interfering with signal transmissions. Another thing I really liked was the inclusion of gold-coated RCA terminals.I was able to toggle between my stereo and phone with ease thanks to the dedicated phone/CD input.
The unit featured pretty much all the ins and outs that you could need in an equalizer.At the same time, the lower cutoff wasn’t so high that I could never any of the extreme low-end if I wanted to.If there was a bass-heavy song that my speakers were having trouble with I could simply increase the cutoff of the low pass filter and dial out the sub-bass.The included subwoofer level and frequency controls really helped me take control of the low-end.First of all, I found the frequency response of the unit to be nothing short of excellent, covering all bases from the extreme lows to the extreme highs.However, ultimately, I chose the BOSS Audio Systems AVA1210 Parametric Equalizer. So it wasn’t so much a matter of which sounded the best. They were all quite responsive and I was able to get the exact tones I wanted out of each EQ.
