6OPERATIONPower OnConnect your signal source (such as an A/V receiver or preamplifier) to thetransmitter (if using a wireless connection) or to the subwoofer (if using a wiredconnection). Two single-RCA cords are provided. While you would ordinarilyuse the short cable to connect to the transmitter or the long one to connectto the subwoofer, either cable can be used, depending on proximity to thesignal source. There is no need or benefit gained from connecting the samesource to both the transmitter and the subwoofer. However, you could connecttwo separate sources to the subwoofer by utilizing both its wired and wirelessconnections. Both signals will essentially be mixed and outputted by thesubwoofer. Plug your transmitter’s (if using a wireless connection) and subwoofer’sAC cord into a wall outlet. Do not use the outlets on the back of the receiverfor 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 amoderate level.Auto On/StandbyTransmitter (Wireless Connection Only): The Status LED (not shown) will belit in red when the unit is in Standby. When the transmitter receives an audiosignal from the source, it will immediately turn on and the LED will turn toblinking green or solid green:RED = STANDBY (No signal detected, transmitter off)GREEN (BLINKING) = Transmitter is on but has not established a linkwith the wireless subGREEN (SOLID) = Transmitter is on and has already established a linkwith the wireless subThe transmitter will automatically enter Standby mode after approximately10 minutes when no signal is detected from your system.Subwoofer: With the Power Switch ¡ in the “On”position, the Status LED onthe 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 subwoofer will automatically enter Standby mode after approximately10 minutes when no signal is detected from your system. The subwoofer will thenpower 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 of nonoperation (e.g., when you are away on vacation).Getting StartedConfirm that the Status LED on the transmitter is on (red or green), theStatus LED on the subwoofer is on (red, orange or green) and an RCA cable isconnected from a source unit to either the LFE Input of the subwoofer £ ortransmitter ‹ or L and R inputs ™ on the subwoofer. Play a CD or video. Usea selection that has ample bass information. If using a wireless connection, theStatus LED on the transmitter should be lit in solid green, and the Status LEDon the subwoofer should turn orange if connected wirelessly. If the LED on thetransmitter 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 thesubwoofer. If connecting directly to the subwoofer without using the wirelesslink, the Status LED on the subwoofer should be lit green. If the LED on thesubwoofer remains red, check that the RCA cable from the source to subwoofer(wired connection) or transmitter (wireless connection) is functioning properlyand that it is fully inserted at both ends, or that the Transmitter ID-CodeSelector and the Subwoofer ID-Code Selector ∞ are set to the samechannel. Once you have a green or orange LED on the subwoofer, turn yourSubwoofer-Level Control ¶ up halfway so that the knob indicator points up.You should now be hearing bass information coming from the subwoofer.Adjust LevelSet the overall volume control of the preamplifier or stereo to a comfortablelevel. Adjust the Subwoofer-Level Control ¶ until you obtain a pleasing blendof bass. Bass response should not overpower the room but rather be adjustedso there is a harmonious blend across the entire musical range. Many usershave a tendency to set the subwoofer volume too loud, adhering to the beliefthat a subwoofer is there to produce lots of bass. This is not entirely true.A subwoofer is there to enhance bass, extending the response of the entiresystem so the bass can be felt as well as heard. However, overall balancemust be maintained or the music will not sound natural. An experienced listenerwill set the volume of the subwoofer so its impact on bass response is alwaysthere but is never obtrusive.Phase ControlThe Phase Switch • determines whether the subwoofer driver’s piston likeaction 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 • tomaximize bass output at the listening position.Crossover AdjustmentThe Crossover Adjustment Control § determines the highest frequencyat which the subwoofer reproduces sounds. If your main speakers cancomfortably reproduce some low-frequency sounds, set this control to alower frequency setting, between 50Hz and 100Hz. This will concentrate thesubwoofer’s efforts on the ultradeep bass sounds required by today’s filmsand music. If you are using smaller bookshelf speakers that do not extendto the lower bass frequencies, set the Crossover Adjustment Control § toa higher setting, between 120Hz and 150Hz.NOTE: This control will have no effect if the LFE Input £ is used (wiredconnection) or if the Low-Pass Selector ¢ is in the “OFF” position (wirelessconnection). If you have a Dolby Digital or DTS processor/receiver, the low-passfrequency is set by the processor/receiver. Consult your owner’s manual to learnhow to view or change this setting.ID CodesIn the unlikely event that you experience interference when operating the system,or if you have more than one set of subwoofer transmitters and receivers inoperation, you may change the channel in which the system operates. Onthe transmitter module and the subwoofer, there is a four-position ID-CodeSelector ( and ∞). Simply set the selectors to one of the other positions.The transmitter and subwoofer ( and ∞) selectors must be set to the sameposition for the system to function correctly. You can also set up a maximum oftwo subwoofers to be receiving from the same transmitter by setting the channelselector on the transmitter and both of the subwoofers to the same channel.A Word About Wireless ProductsThe JBL ES150PW and ES250PW wireless subwoofers utilize advanced wirelesstransceivers operating in the 2.4GHz frequency band. This is the same frequencyband that is used for wireless home networks and high-quality cordless phones.It also allows for the transmission of high-performance, full-spectrum sound toremote locations, wirelessly.Like all wireless devices, the JBL wireless subwoofer’s operating range mayvary, depending upon variables such as building construction methods andmaterials, atmospheric conditions and other sources of interference. Pleaseconsult your JBL dealer or distributor, or visit www.jbl.com, for furtherinformation or assistance.Wall-Mounting the Transmitter ModuleNOTE: The customer is responsible for the correct selection and use ofmounting hardware (available through hardware stores) that will ensure theproper and safe wall-mounting of the transmitter.1. Insert the two M3 x 4 machinescrews through the wall bracketand into the rear of the transmittermodule, as shown.2. Attach the transmitter modulewith wall bracket to the wall,using suitable hardware and,if necessary, wall anchors.ES150PW8
