JBL continually strives to update and improve existing products, as well as create new ones. The specifications
and details in this and related JBL publications are therefore subject to change without notice.
* The Peak Dynamic Power is measured by recording the highest center-to-peak voltage measured across the output of a resistive load equal to
minimum impedance of the transducer, using a 50Hz sine wave burst, 3 cycles on, 17 cycles off.

ES250PW
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 subwoofer (if using a wired
connection). Two single-RCA cords 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 the subwoofer. However, you could connect
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 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 Status 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 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.
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 may 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 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 £ 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 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 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 subwoofer
(wired connection) 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 ∞ are set to the same
channel. 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 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 the subwoofer volume too loud, adhering to the belief
Downloaded from www.Manualslib.com manuals search engine
Phase Control
The Phase Switch • determines whether the subwoofer driver’s 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 bass output at the listening position.
Crossover Adjustment
The 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 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 £ 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. Consult your owner’s manual to learn
how to view or change this setting.
ID Codes
Subwoofer: With the Power Switch ¡ in the “On”position, the Status 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)
6
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 is never obtrusive.
8
In the unlikely event that you experience interference when operating the system,
or if 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 (B and ∞). Simply set the selectors to one of the other positions.
The transmitter and subwoofer (B 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 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 construction methods and
materials, atmospheric conditions and other sources of interference. Please
consult your JBL dealer or distributor, or visit www.jbl.com, for further
information or assistance.
Wall-Mounting the Transmitter Module
NOTE: The customer is responsible for the correct selection and use of
mounting hardware (available through hardware stores) that will ensure the
proper and safe wall-mounting of the transmitter.
1. Insert the two M3 x 4 machine
screws through the wall bracket
and into the rear of the transmitter
module, as shown.
2. Attach the transmitter module
with wall bracket to the wall,
using suitable hardware and,
if necessary, wall anchors.

ES250PW Transmitter. Assure the power supply has been plugged in and a Red or blinking Green LED is
now showing on the transmitter. Default “ID Code” switch position is 1.
2) Position and plug in the ES250PW Subwoofer nearby (less than 75’ away), power switch should be OFF.
3) CROSSOVER, PHASE switch position does not matter. Low Pass switch should be OFF. “ID Code”
switch position should be 1.
4) Turn the LEVEL control on the UUT to completely counterclockwise (MIN).
5) Turn on signal generator; adjust to 75mV, 50 Hz. LED on Transmitter should now be steady Green.
6) Turn the power switch ON. LED on top of Subwoofer should be momentarily Green, then Orange.
7) Turn LEVEL control full clockwise (MAX); immediate and vigorous bass response should be heard and felt
from port tube opening on the bottom.
8) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable.
General Unit Function (Direct connection - No Transmitter)
9) From a mono output signal generator, OFF at this time, connect an RCA cable to the L/R jacks on the
ES250PW Subwoofer.; Use a Y-cable to connect to both inputs; power switch should be OFF.
10) PHASE switch position does not matter. CROSSOVER control should be set at “150Hz”. Low Pass switch
position does not matter.
11) Turn the LEVEL control on the UUT to completely counterclockwise (MIN).
12) Turn on signal generator; adjust to 75mV, 50 Hz.
13) Turn the power switch ON. LED on top of Subwoofer should be momentarily Red, then Green.
14) Turn LEVEL control full clockwise (MAX); immediate and vigorous bass response should be heard and felt
from port tube opening on the bottom.
15) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable.

Sweep Function
1) Follow steps 9-14 above, using a sweep generator as a signal source.
2) Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or
any other noises. If any unusual noises are heard, remove woofer and test.
Driver Function
1) Remove woofer from cabinet; detach + and - wire clips.
2) Check DC resistance of woofer; it should be 3.6 ohms ±10%
3) Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier
fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
4) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.

LM5008
High Voltage (100V) Step Down Switching Regulator
General Description
Features
The LM5008 Step Down Switching Regulator features all of
the functions needed to implement a low cost, efficient, Buck
bias regulator. This high voltage regulator contains an 100 V
N-Channel Buck Switch. The device is easy to implement
and is provided in the MSOP-8 and the thermally enhanced
LLP-8 packages. The regulator is based on a hysteretic
control scheme using an ON time inversely proportional to
VIN. This feature allows the operating frequency to remain
relatively constant. The hysteretic control requires no loop
compensation. An intelligent current limit is implemented
with forced OFF time, which is inversely proportional to Vout.
This scheme ensures short circuit protection while providing
minimum foldback. Other protection features include: Thermal Shutdown, VCC under-voltage lockout, Gate drive undervoltage lockout, and Max Duty Cycle limiter

x RCL))
A resistor between this pin and RTN sets the
off-time when current limit is detected. The off-time
is preset to 35µs if FB = 0V.
Ground pin
Ground for the entire circuit.
Feedback input from Regulated Output
This pin is connected to the inverting input of the
internal regulation comparator. The regulation
threshold is 2.5V.
On time set pin
Ton = 1.25 x 10-10 RON / VIN
A resistor between this pin and VIN sets the switch
on time as a function of VIN. The minimum
recommended on time is 400ns at the maximum
input voltage. This pin can be used for remote
shutdown.
VCC
Output from the internal high voltage series pass
regulator. Regulated at 7.0V.
If an auxiliary voltage is available to raise the
voltage on this pin, above the regulation setpoint
(7V), the internal series pass regulator will
shutdown, reducing the IC power dissipation. Do not
exceed 14V. This voltage provides gate drive power
for the internal Buck switch. An internal diode is
provided between this pin and the BST pin. A local
0.1µF decoupling capacitor is recommended. Series
pass regulator is current limited to 10mA.

Philips Semiconductors
Product specification
8-bit parallel-in/serial-out shift register
74HC/HCT165
When PL is HIGH, data enters the register serially at the
Ds input and shifts one place to the right
(Q0 → Q1 → Q2, etc.) with each positive-going clock
transition. This feature allows parallel-to-serial converter
expansion by tying the Q7 output to the DS input of the
succeeding stage.
FEATURES
• Asynchronous 8-bit parallel load
• Synchronous serial input
• Output capability: standard
• ICC category: MSI
The clock input is a gated-OR structure which allows one
input to be used as an active LOW clock enable (CE) input.
The pin assignment for the CP and CE inputs is arbitrary
and can be reversed for layout convenience. The
LOW-to-HIGH transition of input CE should only take
place while CP HIGH for predictable operation. Either the
CP or the CE should be HIGH before the
LOW-to-HIGH transition of PL to prevent shifting the data
when PL is activated.
GENERAL DESCRIPTION
The 74HC/HCT165 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT165 are 8-bit parallel-load or serial-in shift
registers with complementary serial outputs (Q7 and
Q7) available from the last stage. When the parallel load
(PL) input is LOW, parallel data from the D0 to
D7 inputs are loaded into the register asynchronously.
APPLICATIONS
• Parallel-to-serial data conversion

Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where:
fi = input frequency in MHz
fo = output frequency in MHz
∑ (CL × VCC2 × fo) = sum of outputs
CL = output load capacitance in pF
VCC = supply voltage in V
2. For HC the condition is VI = GND to VCC
For HCT the condition is VI = GND to VCC − 1.5 V

RST
1
Reset (Input) - The device enters a low power mode and all internal state machines are reset to
the default settings when low. RST should be held low during power-up until the power supply,
master and left/right clocks are stable.
SDATA
2
Serial Audio Data (Input) - Two’s complement MSB-first serial data is input on this pin. The
data is clocked into SDATA via the serial clock and the channel is determined by the Left/Right
clock. The required relationship between the Left/Right clock, serial clock and serial data is
defined by the DIF1-0 pins. The options are detailed in Figures 16-19.
SCLK
3
Serial Clock (Input) - Clocks the individual bits of the serial data into the SDATA pin. The
required relationship between the Left/Right clock, serial clock and serial data is defined by the
DIF1-0 pins. The options are detailed in Figures 16-19.
The CS4340 supports both internal and external serial clock generation modes. Internal SCLK
mode is used to gain access to extra de-emphasis modes.
Internal Serial Clock Mode - In the Internal Serial Clock Mode, the serial clock is internally
derived and synchronous with the master clock and left/right clock. The SCLK/LRCK frequency
ratio is either 32, 48, or 64 depending upon the DIF1-0 pins as shown in Figures 16-19. Operation in this mode is identical to operation with an external serial clock synchronized with LRCK.
External Serial Clock Mode - The CS4340 will enter the External Serial Clock Mode whenever
16 low to high transitions are detected on the SCLK pin during any phase of the LRCK period.
The device will revert to Internal Serial Clock Mode if no low to high transitions are detected on
the SCLK pin for 2 consecutive periods of LRCK.

SUMMARY DESCRIPTION
The STM809/810/811/812 MICROPROCESSOR
RESET Circuits are low-power supervisory devices used to monitor power supplies. They perform
a single function: asserting a reset signal whenever the VCC supply voltage drops below a preset
value and keeping it asserted until VCC has risen
above the preset threshold for a minimum period
of time (trec). The STM811/812 also provide a
push-button reset input (MR).
