What Does a Parametric Equalizer Do?, Width

At this point, you may simply enter the data you just STOP measured into the R.A.B.O.S. calculator, found on the

Infinity Web site at www.infinitysystems.com. After entering the data, this R.A.B.O.S. wizard will return the correct settings for all three R.A.B.O.S. controls: ¶, • and ª. Skip to page 14 and adjust these controls as described, and finish the R.A.B.O.S. setup. If you would like to manually calculate the R.A.B.O.S. settings, simply continue following the instructions from this point.

What Does a Parametric Equalizer Do?

The R.A.B.O.S. system uses one band of parametric equalization for response correction. Parametric equalizers are the most versatile class of filters. The effect an equalizer will have on the signal is dependent on three parameters.

Frequency: The equalizer will have maximum effect at one frequency, usually described as the center frequency.

Level: This refers to the amount of cut (in dBs) the equalizer is set for.

Bandwidth: Defines the range of frequencies over which the equalizer will have an effect. On the TSS-SUB4000, this adjustment is abbreviated as “Width.”

Only parametric equalizers allow independent adjustment of all three parameters.

These will be explained more fully in the sections that follow.

Completing the Measurement Template

Along the bottom of the Measurement Template are three fields where you will enter the equalizer settings needed to complete system optimization.

These instructions are based on the example in Figure 12. Use this tutorial to become familiar with the process. Strategies for several other test results will be presented later. After you have completed these three entry fields, you will be ready to perform the adjustments, completing R.A.B.O.S. optimization.

Frequency

The frequency of the R.A.B.O.S. equalizer may be adjusted to any one of nineteen frequencies from 20Hz to 80Hz. This defines where you are going to apply equalization.

Width

The frequency range of the R.A.B.O.S. equalizer may be set from 5% to 50% of an octave in 21 steps. This setting defines how much of the TSS-SUB4000’s output will be equalized.

Figure 12. Effect of adjustable width

Width is expressed as a percentage of an octave. For example, a width setting of 25% means the equalizer will affect a frequency band of 1/4 of an octave; 1/8 of an octave above and 1/8 of an octave below the center frequency.

The octave is a logarithmic expression. From any point in the spectrum, one octave above or below that point is always double or half the frequency. Therefore, one octave above 100Hz would be 200Hz. One octave below 100Hz is 50Hz.

In the section that follows, we will discuss the use of the Width Selector.
