[. . . ] CASCADE TM Compact Powered Subwoofer MODEL TWELVE Owner's Guide (230V) ENGLISH IMPORTANT SAFETY PRECAUTIONS READ FIRST! Attention should be drawn to the environmental aspects of battery disposal. Upon completion of any service or repairs to this product, ask the service technician to perform safety checks to determine that the product is in proper operating condition. When positioning, or moving this product ensure that is lifted rather than dragged across any floor/ mounting surface. This will avoid any damage to the floor/ mounting surface. Attention!Products and/or product feet constructed of rubber or plastics may, in seldom cases, react chemically and discolor treated or non-treated wooden surfaces if positioned without protection. [. . . ] EXAMPLE:The test frequency is 100Hz and the level indicated is ­2dB. Find the intersection of 100Hz (X-axis) and ­2dB (Y-axis). See Figure 7. When you have completed the 23 measurements, you are ready to analyze the data and make corrective adjustments. The completed Measurement template will look something like the example in Figure 9. Figure 9. template Now connect the dots as shown in Figure 10. This will make interpretation of the data much easier. Figure 7. Locating a test point It takes a few seconds for the RSLM reading to stabilize, especially at very low frequencies. Give each test adequate time for the meter to stabilize. At the bottom of the bar graph is a green "ON"LED. This LED is illuminated whenever the sound level is below the measuring range of the RSLM. If this occurs during a test, place a dot at the intersection of the test frequency and the bottom frame of the template. Test example with dots connected 2 Figure 8. Indicating an under-range test When finished, press Skip >>I to advance to the next test. Repeat the process described above for Tracks 5 through 26. CASCADE MODEL TWELVE 8 ENGLISH At this point, you may simply enter the data you just 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. Skip to page 14 and adjust these controls as described, and finish the R. A. B. O. S. If you would like to manually calculate the R. A. B. O. S. settings, simply continue following the instructions from this point. STOP 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 Cascade Model Twelve's output will be equalized. 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. [. . . ] It is recommended that you remove the battery from the RSLM. Store the Test CD, Width Selector, Adjustment Key and the RSLM together. On Off After performing these adjustments, you may skip forward to the "Final System Balance"section. It is recommended that you perform a second measurement to confirm that the settings are correct. If you are going to retest the system after EQ adjustments, repeat the "Setting the Subwoofer Test Level"section on page 7. [. . . ]
