29. tant determinants of bass quantity and quality In most practical situations there is little that can be done about this except for patient trial and error repositioning of the loudspeakers and listeners Usually the practical constraints of a living space and the impracticality of massive acoustical treatment mean that equalization is the only practical solution Professional sound engineers routinely employ sophisticated measurement systems and equalizers to optimize speakers to the installation This has never been practical for the home audiophile This is why R A B 0 S was created R A B 0 S enables you to identify the dominant low frequency response characteristic of your room Once you know the problem R A B 0 S provides the tools needed to optimize the low frequency characteristics of the speakers to the room they are in exactly as the professional sound engineers do it 5 TSS SUBA000 Performing R A B 0 S Tests These instructions assume you have already installed your subwoofer according to the information provided in the Owner s Guide It is also assumed that all equipment in your entertainment system is interconnected properly and is in good operating condition Preparations Before beginning R A B O S tests please check the following Set R A B 0 S switch to On position Make sure all three R A B 0 S controls and on the subwoofer are turned fully clockwise Make sure the loudne

31. this R A B 0 S wizard will return the correct much of the TSS SUB4000 s output will be equalized settings for all three R A B 0 S controls and Skip to page 14 and adjust these controls as described and finish the R A B 0 S setup If you would like to manually calculate the R A B 0 8 settings simply continue following the instructions from this point What Does a Parametric Equalizer Do The R A B 0 8 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 nid d H BE wae eee EIN Level This refers to the amount of cut in dBs the equalizer is set for Figure 12 Effect of adjustable width Bandwidth Defines the range of frequencies over which the Width is expressed as a percentage of an octave For example a equalizer will have an effect On the TSS SUB4000 this width setting of 25 means the equalizer will affect a frequency adjustment is abbreviated as Width band of 1 4 of an octave 1 8 of an octave above and 1 8 of an octave below the center frequency Only parametric equalizers allow independent adjustment of all three parameters B The octave is a logarithmic expression From any point in the spec
32. trum 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 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 In the section that follows we will discuss the use of the where you will enter the equalizer settings needed to complete Width Selector 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 0 S optimization Frequency The frequency of the R A B 0 S equalizer may be adjusted to any one of nineteen frequencies from 20Hz to 80Hz This defines where you are going to apply equalization 74 TSS SUBA000 Using the Width Selector QD Read the following instructions carefully The example presented may not look like the graph you just created Focus on the concepts and techniques presented Specific cases will be discussed later Figure 13 Width Selector You will use the Measurement Template just completed and the Width Selector to determine the correct width setting The Width Selector graphically depicts a single resonant peak The peak looks si
