INFINITY CLASSIA PSW310W ™ The Infinity Classia PSW310W continues the legendary Infinity® dedication to accurate sound reproduction.The patented Ceramic Metal Matrix Diaphragm (CMMD®) drivers, high-powered amplifier and proprietary Room Adaptive Bass Optimization System™ (R.A.B.O.S.™) technology, along with a rigid, well-braced enclosure, combine to deliver uncompromised bass performance in any stereo or multichannel home theater.

OPERATION Power On Connect your signal source (such as an A/V receiver or preamplifier) to the transmitter (if using wireless connection) or to the subwoofer (if using wired connection).Two single-RCA cords are provided. While you would ordinarily use the short cable to connect to the transmitter or the long one to connect to the subwoofer, either cable can be used, depending on proximity to the signal source.
Wall-Mounting the Transmitter Module The R.A.B.O.S. Goal NOTE: The customer is responsible for the correct selection and use of mounting hardware (available through hardware stores) that will ensure the proper and safe wall-mounting of the transmitter. It is a fact of audio that what we hear at low frequencies is determined as much or more by the listening room than by the loudspeaker itself.
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. Press Play ›. With the RSLM positioned as described above, increase the system volume until the RSLM display indicates –10dB. See Figure 4. Figure 4.
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 R.A.B.O.S. Measurement Template (this is called the X-axis). See Figure 6 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: ¤, C and D. 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 13. Placement of the Bandwidth Selector Figure 12. Width Selector You will use the R.A.B.O.S. 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 R.A.B.O.S. 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 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. Perform corrections on the upper frequency peak.
1. Select a new test position: Cue the test track corresponding to the center frequency of the dip. In the first example in Figure 18, you would play Track 13 (56Hz). 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. As you move the RSLM, watch the bar graph.You will observe large level fluctuations.
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. As you move the RSLM, watch the bar graph.You will observe large level fluctuations.
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 clean.
