OPERATING / SERVICE MANUAL GE 14/GE 27

GRAPHIC EQUALIZERS

QUICK START

The GE 27 and GE 14 are extremely accurate instruments capable of precise equalization down to a fraction of a dB.

However, equalizing a sound system by ear is very difficult to do with any degree of accuracy, even with years of

training.

To obtain the best performance from your equalizer it is strongly recommended that you use some type of realtime

analyzer. Any equalizer used in conjunction with a well designed analyzer system will be significantly more effective in

reducing feedback and providing consistent, optimum sound quality in varying acoustical environments.

If you don’t have an analyzer (such as the Rane RA 27), then you will have to resort to Section 2408, paragraph 84-B

of the Performing Musicians Code, which reads:

“Fiddle with it until it sounds good.”

This fiddling process can be both time-consuming and frustrating with a 1/3 or 2/3 octave equalizer––you can end up

chasing your own tail until all the sliders wind up at full boost, unless you have a basic procedure to follow. If you

haven’t one of your own, here’s a procedure you might try.

Point to remember: All things are relative. This applies especially well to tonal perception. What sounds like too little

bass could really be too much midrange, and so on.

The idea is to start with some frequency area and use it as a reference for further comparison; then leave this area

pretty much alone and make your adjustments elsewhere. Otherwise you might wind up hopelessly trapped in Murphy’s

EQ Syndrome, which roughly reads:

“O.K., we need more low end here; now add a little presence at 10k or so; hmmm, mid range is off a little, so I’ll

bump up 800 and 1k; now I need more punch, so up with 80, 100 and 125; darn, presence is still not there, so more of the

5k and 6.3k, vocals seem a little buried—needs more 1.25k and 1k...” and so on until all the sliders are near full boost

and you have a high-dollar volume control.

To avoid this, choose an area in which you know your speakers perform well, such as around 1kHz. Leave this area at

roughly center position on the sliders and then compare bass, mid bass, mid highs and highs to the 1kHz area. Then if, for

example, the overall sound appears to be “boomy”, muddy, or lacking in midrange, turn down the mid bass and/or mid

highs––don’t turn up the 1kHz midrange area instead, or you’ll be headed right into the vicious circle.

Once you are familiar with your own system, you will develop your own procedure. The golden rule is:

“Whatever Works, Works.”
