How to Set an Adjusting Analog Graphic Equalizer Smile

An analog graphic equalizer adjusts the audio frequencies of stereo components for a custom sound when played back on speakers. The equalizer "smile" is a popular setting of the audio frequencies named for the shape of the slider controls that curve upward on the ends for the bass and treble settings, with low control settings for the mid-range. While countless variations are available for the equalizer smile, each control can be set in slightly different increments. Thus, the basic setting is a good starting point for fine-tuning the slide controls to personal taste.

Instructions

1. Slide the two outermost controls, on the far left and right, to the top positions on the equalizer.

2. Set the next two controls one setting below the far left and right controls.

3. Adjust the third control from the left and right one step below the second controls.

4. Push down the next pair of controls another step. Continue with each control until the two middle sliders are at the bottom position. The slider controls now resemble the upward curve of a smile. This setting accentuates the high and low frequencies, while minimizing the middle range.

Tips & Warnings

• Use the marked gradations on the equalizer as a guide to the smile setting. Equalizers adjust at different frequency increments, depending on the model. Experiment with the settings to sculpt the sound to suit your individual taste; the "smile" curve is merely a reference point for setting equalization. Personal preferences take precedent over any standard setting.
