Connect a subwoofer cable from the subwoofer or LFE output of your receiver to the Sub In ?on the transmitter. Step 2. Plug

24、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 position,as described on page 4.When connected prop

25、erly, 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 subwoofer Classia Series INFINITY CLASSIA PSW310W (

26、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 control of the preamplifier or stereo to a comfortabl

27、e 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 the subwoofer volume too loud,adhering to the belie

28、f 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 will not sound natural.An experienced listener wi

29、ll 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 the main speakers,180.Proper phase adjustment dep

30、ends 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 which the subwoofer reproduces sounds.If your mai

31、n 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 using smaller bookshelf speakers that do not ext

32、end 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 (wireless connection).If you have a Dolby Digital

33、 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 you have more than one set of subwoofer transmit

34、ters 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 transmitter and subwoofer (?and ) selectors must be set to

35、 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 About Wireless Products The Infinity Classia PSW

36、310W 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- performance,full-spectrum sound to remote locat

37、ions,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 consult your Infinity dealer or distributor, or vi

38、sit ,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 are provided.While you would ordinarily use the s

39、hort 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 the subwoofer.However,you could connect two separat

40、e 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 not use the outlets on the back of the receiver fo

41、r 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 Transmitter (wireless connection only):The Power

42、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 detected,transmitter off) GREEN (BLINKING) = Transmitter

43、 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 signal is detected from your system. Subwoofer:With th

44、e 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 (Wireless link with transmitter active) The subwoofe

45、r 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 may turn off the Power Switch for extended periods

46、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 is connected from a source unit to either the LF

47、E 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 LED on the subwoofer should turn orange if conne

48、cted 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 the wireless link,the Status LED on the subwoofe

49、r 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 at both ends,or that the Transmitter ID-Code Selector ? and the Subwoofer ID-Code Selec
