Jerry(i assume) have you actually tried that?If you have ,do you adjust the levels so they all read the same db level(flat)Or do you boost the low end and hi end somewhat?


You try to make it as flat as possible. The idea is that with a completely flat eq you will hear the sound that the recording engineer wanted you to hear.

In practice, because everyone's ears are different and personal preferences come into play that doesn't always completely work.

The main object of equali[s|z]ation is to eliminate resonances and reinforce 'dead' frequencies to get the sound as flat as possible.

5 parametic eqs should be enough to do a reasonable job when you consider the variable Q, and the fact that wind-noise and road vibrations etc are never going to allow you a perfect AVIA-reference listening environment. Most of what makes good eq sound good is actually the removal of the biggest 3 or 4 problems (be it resonances or dead frequencies). After that, you're starting to split hairs...unless you have reference quality speakers in a perfect listening environment and perfect hearing you are going to be hard pushed to do much better.

So my suggestion is to use 4 of the 5 eqs to level as much of the sound as possible, and leave the 5th flat. Copy this to all of your eq modes, and then adjust the 5th eq in ewach mode with a very small Q factor to adjust bass or treble. (Try around 150Hz, Q=0.5 for bass and around 8kHz,Q=0.5 for treble as starting points, the small Q factor means that your boost/cut is spread over a relatively wide range of frequencies. If you feel that the adjustment is affecting too big a range, then increase Q and vice-versa.)

You need to make sure that you adjust any meter reading against the calibration chart provided with the unit. Lower frequencies read with a lower dB value.
