OPERATION
Power On
Connect your signal source (such as an A/V receiver or preamplifier)
to the transmitter (if using a wireless connection) or to the sub-
woofer (if using a wired connection). Two single-RCA cords are pro-
vided. 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 the subwoofer. However, you could con-
nect two separate sources to the subwoofer by utilizing both its
wired and wireless connections. Both signals will essentially be
mixed and outputted by the subwoofer. Plug your transmitter’s (if
using a wireless connection) and subwoofer’s AC cord into a wall
outlet. Do not use the outlets on the back of the receiver for the sub-
woofer.
Initially set the Subwoofer-Level Control
6
to the “min” position.
Turn on your sub by pressing the Power Switch
0
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 Status LED (not
shown) will be lit in red when the unit is in Standby. When the trans-
mitter 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 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 approxi-
mately 10 minutes when no signal is detected from your system.
Subwoofer: With the Power Switch
0
in the ON position, the Status
LED on the top 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 the 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
0
can be
left on. You may turn off the Power Switch
0
for extended periods
of nonoperation, e.g., when you are away on vacation.
Getting Started
Confirm that the Status LED on the transmitter is on (red or green),
the Status LED on the subwoofer is on (red, orange or green) and an
RCA cable is connected from a source unit to either the LFE Input of
the subwoofer
2
or transmitter
C
or L and R inputs
1
on the sub-
woofer. 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 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 sub-
woofer without using the wireless link, the Status LED on the sub-
woofer should be lit green. If the LED on the subwoofer remains red,
check that the RCA cable from the source to subwoofer (wired con-
nection) or transmitter (wireless connection) is functioning properly
and that it is fully inserted at both ends, or that the Transmitter ID-
Code Selector
B
and the Subwoofer ID-Code Selector
4
are set to
the same channel. Once you have a green or orange LED on the sub-
woofer, turn your Subwoofer-Level Control
6
up halfway so that the
knob indicator points up. You should now be hearing bass informa-
tion coming from the subwoofer.
Adjust Level
Set the overall volume control of the preamplifier or stereo to a
comfortable level. Adjust the Subwoofer-Level Control
6
until you
obtain a pleasing blend of bass. Bass response should not over -
power 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 belief that 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
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 will set the volume of the subwoofer
so its impact on bass response is always there but never obtrusive.
Phase Control
The Phase Switch
7
determines whether the subwoofer speaker’s
pistonlike 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 bass output at
the listening position.
Crossover Adjustment
The Crossover Adjustment Control
5
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
100Hz. This will concentrate the subwoofer’s efforts on the ultradeep
bass sounds required by today’s films and music.
If you are 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
2
is used
(wired connection) or if the Low-Pass Selector
3
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 proces-
sor/receiver. Consult your owner’s manual to learn how to view or
change this setting.
ID Codes
In the unlikely event that you experience interference when operat-
ing the system, or if you have more than one set of subwoofer trans-
mitters and receivers in operation, you may change the channel in
which the system operates. On the transmitter module and the sub-
woofer, there is a four-position ID-Code Selector (
B
and
4
). Simply
set the selectors to one of the other positions. The transmitter and
subwoofer (
B
and
4
) 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 set-
ting the channel selector on the transmitter and both of the sub-
woofers to the same channel.
A Word About Wireless Products
The JBL ES150PW and ES250PW wireless subwoofers utilize
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 locations, wirelessly.
Like all wireless devices, the JBL wireless subwoofer’s operating
range may vary, depending upon variables such as building con-
