IMPORTANT SAFETY PRECAUTIONS READ FIRST! 12. Use only with the cart, stand, tripod, bracket or table specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualified service personnel.

CONNECTIONS 3 If you have a Dolby* Digital or DTS® receiver/processor with a low-frequency-effects (LFE) output: If your receiver/processor has subwoofer outputs for the left and right channels: • Set Low-Pass Switch to Off. • Set Low-Pass Switch to On. NOTE: In this case, you do not need to use a Y connector. Simply connect the LFE output on your receiver/processor to either the left or right input on the subwoofer.
OPERATION Power On Low-Pass Selector Plug your subwoofer’s AC cord into a wall outlet. Do not use the outlets on the back of the receiver. If you have a Dolby Digital or DTS processor/receiver, the Crossover Frequency is set by the processor/receiver. Consult your owner’s manual to learn how to view or change this setting. In this case, the Low-Pass Selector £ should be set to “Off”. We strongly recommend this setup method. Initially set the Subwoofer Level (Volume) Control ¡ to the “min” position.
ROOM ADAPTIVE BASS OPTIMIZATION SYSTEM 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 TSS-SUB4000 self-amplified subwoofer. The TSS-SUB4000 subwoofer contains a parametric equalizer that you will adjust as indicated by the R.A.B.O.S. test results. Following these instructions, you will optimize the TSS-SUB4000’s response characteristics to complement the sub’s environment.
Contents of the R.A.B.O.S.
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. or rattle during this test, it is highly recommended that you locate the source and eliminate its effects.This is actually a valuable room-diagnostic tool. Press Play ›.
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. Each frequency point is listed across the bottom of the Measurement Template (this is called the X-axis). See Figure 7 on the previous page.
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. 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.
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 14. Placement of the Bandwidth Selector 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 pointer on the slider will indicate the correct width setting. Enter this number in the Width field of the Measurement Template. In our example, the width is 12.5%. Example 1. Single Dominant Peak: It is not realistic to expect a perfect fit. Acoustic measurements encompass the behavior of not only the speakers but of the room and its contents as well. Reflected energy, standing waves and ambient noise all add their part. Determining the best width setting nearly always requires compromise.
Example 2. Two Response Peaks: Example 3. Peak Adjacent to a Dip: Figure 17.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. Perform corrections on the upper frequency peak.
2. Reset the test level: Return to the section “Setting the Subwoofer Test Level” on page 7. Perform the procedure as described. Determine the appropriate level using the technique described earlier. In this example, –13dB is indicated. Enter 13 in the field provided. 3. Repeat the measurements: Now that you are familiar with the measurement process, you can go much faster by using Tracks 27–50.These tracks contain all the test tones necessary for measurement.
2. Reset the test level: Return to the section “Setting the Subwoofer Test Level” on page 7. Perform the procedure as described. If your test data looks similar to the example in Figure 22, you have a very favorable setup. Skip to the “Final System Balance” section, page 15. 3. Repeat the measurements: Now that you are familiar with the measurement process, you can go much faster by using Tracks 27–50.These tracks contain all the test tones necessary for measurement.
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. Final System Balance Cue Track 51 of the R.A.B.O.S.Test CD. Press Play ›. Increase the system volume until the RSLM indicates –10dB. Now play Track 52.
MAINTENANCE AND SERVICE The enclosure and grille may be cleaned using a soft cloth to remove fingerprints or to wipe off dust. All wiring connections should be inspected and cleaned or remade periodically.The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions, and other factors, but once per year is the minimum. If a problem occurs, make sure that all connections are properly made and are clean.
