21、o the transmitter ?.Make sure the Transmitter Antenna ?is extended upward.Step 3.Set the ID code on the transmitter and subwoofer (?and )to the same position,as described on page 4.When connected properly,the LED on the rear of the subwoofer will be orange.Step 4.Set the Low-Pass Selector to the “Of

22、f”position.NOTE: Some receivers have two subwoofer outputs.In that case,useeither one of the connectors.Sub InIDCODEDC18V1 2 3 47 PSW310W subwoofer Classia Series INFINITY CLASSIA PSW310W (120V)Once you have a green or orange LED on the subwoofer,turn yourSubwoofer-Level Control up halfway so that t

23、he knob indicatorpoints up.You should now be hearing bass information coming fromthe subwoofer.Adjust LevelSet the overall volume control of the preamplifier or stereo to acomfortable level.Adjust the Subwoofer-Level Control until youobtain a pleasing blend of bass.Bass response should not overpower

24、the room but rather be adjusted so there is a harmonious blend across the entire musical range.Many users have a tendency to set thesubwoofer volume too loud,adhering to the belief that a subwoofer is there to produce lots of bass.This is not entirely true.A subwoofer should enhance bass,extending t

25、he response of the entire system so the bass can be felt as well as heard.However,overall balance must be maintained or the music will not sound natural.An experiencedlistener will set the volume of the subwoofer so its impact on bassresponse is always there but is never obtrusive.Phase ControlThe P

26、hase Switch determines whether the subwoofer drivers piston-like 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.Adjust the Phase Switch to maximize bas

27、s outputat the listening position.Crossover AdjustmentThe Crossover Adjustment Control determines the highest frequency at which the subwoofer reproduces sounds.If your main speakers can comfortably reproduce some low-frequency sounds,set this control to a lower frequency setting,between 50Hz and 10

28、0Hz.This willconcentrate the subwoofers efforts on the ultradeep bass sounds requiredby todays films and music.If you are using smaller bookshelf speakersthat do not extend to the lower bass frequencies,set the CrossoverAdjustment Control to a higher setting,between 120Hz and 150Hz.NOTE: This contro

29、l will have no effect if the LFE Input is used (wired connection) or if the Low-Pass Selector is in the “OFF”position(wireless connection).If you have a Dolby Digital or DTS processor/receiver,the low-pass frequency is set by the processor/receiver.Consultyour owners manual to learn how to view or c

30、hange this setting.ID CodesIn the unlikely event that you experience interference when operatingthe system,or if you have more than one set of subwoofer transmittersand receivers in operation,you may change the channel in which thesystem operates.On the transmitter module and the subwoofer, there is

31、 a four-position ID-Code Selector (?and ).Simply set the selectorsto one of the other positions.The transmitter and subwoofer (?and )selectors must be set to the same position for the system to functioncorrectly.You can also set up a maximum of two subwoofers to bereceiving from the same transmitter

32、 by setting the channel selector on the transmitter and both of the subwoofers to the same channel.A Word About Wireless ProductsThe Infinity Classia PSW310W wireless subwoofer utilizes advancedwireless transceivers operating in the 2.4GHz frequency band.This is the same frequency band that is used

33、for wireless home networks andhigh-quality cordless phones.It also allows for the transmission of high-performance,full-spectrum sound to remote locations,wirelessly.Like all wireless devices,the Infinity PSW310W wireless subwoofersoperating range may vary,depending upon variables such as buildingco

34、nstruction methods and materials,atmospheric conditions and othersources of interference.Please consult your Infinity dealer or distributor,or visit ,for further information or assistance.OPERATIONPower OnConnect your signal source (such as an A/V receiver or preamplifier) to the transmitter (if usi

35、ng wireless connection) or to the subwoofer (if using wired connection).Two single-RCA cords are provided.Whileyou would ordinarily use the short cable to connect to the transmitteror the long one to connect to the subwoofer,either cable can be used,depending on proximity to the signal source.There

36、is no need or benefit gained from connecting the same source to both thetransmitter and the subwoofer.However,you could connect twoseparate sources to this subwoofer by utilizing both its wired andwireless connections.Both signals will essentially be mixed andoutputted by the subwoofer.Plug your tra

37、nsmitters (if using wirelessconnection) and subwoofers AC cord into a wall outlet.Do not use theoutlets on the back of the receiver for the subwoofer.Initially set the Subwoofer-Level Control to the “Min”position.Turn on your sub by pressing the Power Switch on the rear panel.Turn on your entire aud

38、io system and start a CD or movie soundtrackat a moderate level.Auto On/StandbyTransmitter (wireless connection only):The Power Indicator LED (not shown) will be lit in red when the unit is in standby.When thetransmitter receives an audio signal from the source,it will immediatelyturn on and the LED

39、 will turn to blinking green or solid green:RED = STANDBY (No signal detected,transmitter off) GREEN (BLINKING) = Transmitter is on but has not established a linkwith the wireless sub.GREEN (SOLID) = Transmitter is on and has already established a linkwith the wireless sub.The transmitter will autom

40、atically enter Standby mode after approximately10 minutes when no signal is detected from your system.Subwoofer:With the Power Switch in the “On”position,the PowerIndicator LED on the back panel will remain lit to indicate theOn/Standby mode of the subwoofer.RED = STANDBY (No signal detected,amp off

41、)GREEN = SUB ON (Wired signal detected,amp on)ORANGE = SUB ON (Wireless link with transmitter active)The subwoofer will automatically enter Standby mode afterapproximately 10 minutes when no signal is detected from yoursystem.The subwoofer will then power on instantly when a signal isdetected.During

42、 periods of normal use,the Power Switch can beleft on.You may turn off the Power Switch for extended periods ofnonoperation,e.g.,when you are away on vacation.Getting StartedConfirm that the Status LED on the transmitter (not shown) is on (redor green) and the Status (Power Indicator) LED on the sub

43、woofer is on (red,orange or green) and that an RCA cable is connected from a source unit to either the LFE Input of the subwoofer ortransmitter ?or L and R inputs on the subwoofer.Play a CD orvideo.Use a selection that has ample bass information.If using awireless connection,the Status LED on the tr

44、ansmitter should be lit in solid green,and the Status LED on the subwoofer should turnorange if connected wirelessly.If the LED on the transmitter is blinkingin green and the LED on the subwoofer is in red or green,a wirelesslink has not been established between the transmitter and thesubwoofer.If c

45、onnecting directly to the subwoofer without using thewireless link,the Status LED on the subwoofer should be lit green.If the LED on the subwoofer remains red,check that the RCA cable fromthe source to the subwoofer (wired connection) or transmitter (wirelessconnection) is functioning properly (wire

46、d connection) and that it isfully inserted at both ends,or that the Transmitter ID-Code Selector ?and the Subwoofer ID-Code Selector are set to the same channel.8 PSW310W subwoofer Classia Series PSW310W subwoofer Classia Series 9 PSW310W subwoofer Classia Series 10 PSW310W Test Set Up and Procedure

47、 The operation of the PSW310W subwoofer, and the proper settings for the Room Adaptive Bass Optimization System, or R.A.B.O.S., is thoroughly covered in the Owners guide, available from . For service purposes, the R.A.B.O.S. system is canceled when all three front panel controls (F) (L) (W) are turn

48、ed fully CW (Clockwise), or if the R.A.B.O.S. On/Off switch is OFF. The only other control of concern is the Main Level Control on the front panel, which operates like a traditional potentiometer. Equipment needed: Function/signal generator/sweep generator Integrated Amplifier Multimeter Speaker cab

49、les PSW310W Transmitter, power supply General Unit Function + Transmitter (UUT = Unit Under Test) 1) From a mono output signal generator, OFF at this time, connect an RCA cable to the “Sub in” jack on the PSW310W Transmitter. Assure the power supply has been plugged in and a Red or blinking Green LE
