WIRED Connecting the Subwoofer for Wireless Applications Step 1. Connect a subwoofer cable from the subwoofer or LFE output of your receiver

21、 to the Sub In ?on the transmitter. Step 2. Plug the transmitter module into the wall outlet,and connect the included power supply and power cord to 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 po

22、sition,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 “Off”position. NOTE: Some receivers have two subwoofer outputs.In that case,use either one of the connectors. Sub In ID CODE DC18V 1 2 3 4 7 PSW310W su

23、bwoofer Classia Series INFINITY CLASSIA PSW310W (120V) Once you have a green or orange LED on the subwoofer,turn your Subwoofer-Level Control up halfway so that the knob indicator points up.You should now be hearing bass information coming from the subwoofer. Adjust Level Set the overall volume cont

24、rol of the preamplifier or stereo to a comfortable level.Adjust the Subwoofer-Level Control until you obtain a pleasing blend of bass.Bass response should not overpower the room but rather be adjusted so there is a harmonious blend across the entire musical range.Many users have a tendency to set th

25、e subwoofer 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 the response of the entire system so the bass can be felt as well as heard.However,overall balance must be maintained or the music

26、will not sound natural.An experienced listener will set the volume of the subwoofer so its impact on bass response is always there but is never obtrusive. Phase Control The Phase Switch determines whether the subwoofer drivers piston-like action moves in and out with the main speakers,0,or opposite

27、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 bass output at the listening position. Crossover Adjustment The Crossover Adjustment Control determines the highest frequency at

28、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 100Hz.This will concentrate the subwoofers efforts on the ultradeep bass sounds required by todays films and music.If you are

29、 using smaller bookshelf speakers that do not extend to the lower bass frequencies,set the Crossover Adjustment Control to a higher setting,between 120Hz and 150Hz. NOTE: This control will have no effect if the LFE Input is used (wired connection) or if the Low-Pass Selector is in the “OFF”position

30、(wireless connection).If you have a Dolby Digital or DTS processor/ receiver,the low-pass frequency is set by the processor/receiver.Consult your owners manual to learn how to view or change this setting. ID Codes In the unlikely event that you experience interference when operating the system,or if

31、 you have more than one set of subwoofer transmitters and receivers in operation,you may change the channel in which the system operates.On the transmitter module and the subwoofer, there is a four-position ID-Code Selector (?and ).Simply set the selectors to one of the other positions.The transmitt

32、er and subwoofer (?and ) selectors must be set to the same position for the system to function correctly.You can also set up a maximum of two subwoofers to be receiving from the same transmitter by setting the channel selector on the transmitter and both of the subwoofers to the same channel. A Word

33、 About Wireless Products The Infinity Classia PSW310W wireless subwoofer utilizes advanced wireless transceivers operating in the 2.4GHz frequency band.This is the same frequency band that is used for wireless home networks and high-quality cordless phones.It also allows for the transmission of high

34、- performance,full-spectrum sound to remote locations,wirelessly. Like all wireless devices,the Infinity PSW310W wireless subwoofers operating range may vary,depending upon variables such as building construction methods and materials,atmospheric conditions and other sources of interference.Please c

35、onsult your Infinity dealer or distributor, or visit ,for further information or assistance. 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

36、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.There is no need or benefit gained from connecting the same source to both the transmitter and th

37、e subwoofer.However,you could connect two separate sources to this subwoofer by utilizing both its wired and wireless connections.Both signals will essentially be mixed and outputted by the subwoofer.Plug your transmitters (if using wireless connection) and subwoofers AC cord into a wall outlet.Do n

38、ot use the outlets 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 audio system and start a CD or movie soundtrack at a moderate level. Auto On/Standby

39、Transmitter (wireless connection only):The Power Indicator LED (not shown) will be lit in red when the unit is in standby.When the transmitter receives an audio signal from the source,it will immediately turn on and the LED will turn to blinking green or solid green: RED = STANDBY (No signal detecte

40、d,transmitter off) GREEN (BLINKING) = Transmitter is on but has not established a link with the wireless sub. GREEN (SOLID) = Transmitter is on and has already established a link with the wireless sub. The transmitter will automatically enter Standby mode after approximately 10 minutes when no signa

41、l is detected from your system. Subwoofer:With the Power Switch in the “On”position,the Power Indicator LED on the back panel will remain lit to indicate the On/Standby mode of the subwoofer. RED = STANDBY (No signal detected,amp off) GREEN = SUB ON (Wired signal detected,amp on) ORANGE = SUB ON (Wi

42、reless link with transmitter active) The subwoofer will automatically enter Standby mode after approximately 10 minutes when no signal is detected from your system.The subwoofer will then power on instantly when a signal is detected.During periods of normal use,the Power Switch can be left on.You ma

43、y turn off the Power Switch for extended periods of nonoperation,e.g.,when you are away on vacation. Getting Started Confirm that the Status LED on the transmitter (not shown) is on (red or green) and the Status (Power Indicator) LED on the subwoofer is on (red,orange or green) and that an RCA cable

44、 is connected from a source unit to either the LFE Input of the subwoofer or transmitter ?or L and R inputs on the subwoofer.Play a CD or video.Use a selection that has ample bass information.If using a wireless connection,the Status LED on the transmitter should be lit in solid green,and the Status

45、 LED on the subwoofer should turn orange if connected wirelessly.If the LED on the transmitter is blinking in green and the LED on the subwoofer is in red or green,a wireless link has not been established between the transmitter and the subwoofer.If connecting directly to the subwoofer without using

46、 the wireless link,the Status LED on the subwoofer should be lit green. If the LED on the subwoofer remains red,check that the RCA cable from the source to the subwoofer (wired connection) or transmitter (wireless connection) is functioning properly (wired connection) and that it is fully inserted a

47、t 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 The operation of the PSW310W subwoofer, a

48、nd 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 turned 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.
