120Hz and 150Hz. Phase Control The Phase Switch § determines whether the subwoofer speaker’s pistonlike action moves in and out with the main speakers (0˚) or opposite the main speakers (180˚). Proper phase adjustment depends on several variables such as room size, subwoofer placement and listener position. - Page 8 DAPTIVE Infinity’s R.A.B.O.S. is a simple-to-use, yet sophisticated, low-frequency calibration system. It is designed to work in conjunction with the Cascade Model Fifteen self-amplified subwoofer.The subwoofer contains a parametric equalizer that you will adjust as indicated by the R.A.B.O.S. test results.

Page 9: The R.a.b.o.s. Sound-Level Meter (Rslm
THE R.A.B.O.S. SOUND-LEVEL METER (RSLM) The RSLM is a battery-operated, handheld, acoustic measurement device specifically designed for Infinity R.A.B.O.S. On the face of the instrument is a light-emitting diode (LED) bar graph that indicates relative sound level.There are also indicators for power-on, out-of-range signals and a low battery. -
Page 10: Performing Low-Frequency Measurements
Initial System-Level Setting The following steps will set the playback level of the system to the correct level for all tests that follow. Turn the system volume to minimum. Cue the R.A.B.O.S.Test CD to Track 2 and press Pause II.This track will produce band-limited pink noise in both the left and right channels. - Page 11 Each of the following tracks produces a low-frequency test tone. The range of these tests is from 100Hz down to 20Hz.The frequency of each test is announced before it begins.The first test is the highest frequency (100Hz); therefore, you will be marking the template from right to left.

Page 12: Completing The Measurement Template
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 B . Skip to page 14 and adjust these controls as described, and finish the R.A.B.O.S. -
Page 13: Using The Width Selector
Using the Width Selector 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 12. 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 similar to a slice of a pie. -
Page 14: What You Measure, What To Do
Example 1. Single Dominant Peak Figure 15. Single dominant peak This is the most common result of speaker/room interaction. Apply the Width Selector as described in Figure 13. Align the center line of the Selector over the center of the peak, as shown in Figure 14. - Page 15 Example 2. Two Response Peaks Figure 16.Two response peaks Characterized by two response peaks, approximately equal in amplitude and width.This requires that you make a choice between the two peaks. In situations like this, the higher- frequency peak will always be more audible and objectionable. Response peaks below 45Hz, unless extreme, can actually be beneficial toward achieving visceral impact.

Press Play reading very close to what you had before. Now slowly move the RSLM around the area, if possible remaining within about a foot of the original test point.

1. Select a new test position: Cue the test track corresponding to the center frequency of the dip. In the example in Figure 19 you would play Tracks 14 (52Hz) and 18 (40Hz). Press Play ›. You will see a reading very close to what you had before. Now slowly move the RSLM around the area, if possible remaining within about a foot of the original test point. -
Page 18: Final System Balance
If using more than one subwoofer, always adjust both subwoofers together. Adjust the controls as indicated by the Measurement Template. Each value shown in the table is represented by detents in the R.A.B.O.S. controls. Simply count the number of detents necessary, indicated by the results of your R.A.B.O.S.Test. -
