PLACING YOUR SUBWOOFER IN YOUR LISTENING ROOM:
Your listening room or theater is an integral part of your sound reproduction
system. e physical dimensions of the room and its furnishings, materials, doors
and windows play an important role in dening how your system sounds.
When you place a sound source in an enclosed rectangular space, “standing
waves” are created, resulting from the relationship between the sound’s
wavelength and your room’s dimensions. In other words, standing waves result
from sound energy that is trapped in the room as it bounces back and forth
between opposing walls. Standing waves in the room create acoustic peaks and
dips where the sound is either louder or soer, based solely on your physical
position in the room. Energy also “builds up” at the room’s boundaries, creating
exaggerated bass response at certain frequencies. ese fundamental room
resonances are called room “modes”.
e moral of this mode story is to try and avoid seating positions in standing
wave peak or dip regions. It is highly recommended that you place your listening
chairs in areas where modal peaks and dips are moderate and do not reinforce
one another. e two most obvious areas to avoid are those near the exact center
of the room and those close to any of the room’s walls.
Just as your listening seat can be in a peak or dip region, so can your
subwoofer. When placed in a room corner, a subwoofer maximally excites the
room’s mode structure, creating the strongest output with the fewest dips. When
the subwoofer is pulled away from a corner or wall, the room modes are excited
less, which can alter the sound at your listening seat.
Be sure to experiment with both your listening seat position and subwoofer
position to nd the best solution. Careful experimentation usually leads to a
superior sounding system. Use our setup suggestions (illustrated on the opposing
page and the following pages) to get you started.
If you cannot avoid placing your sofa against the back wall or your
subwoofer in a less than optimal position, all is not lost. Your SA-600W’s Digital
Automatic Room Optimization (D.A.R.O.) System can dramatically improve
these less-than-ideal situations.
We recommend that you begin by placing your subwoofer in the front
of the room, on the oor, near the front le or right speaker. Placing the
subwoofer near solid walls will reinforce bass response and pulling it away from
solid walls will decrease bass. Increasing the distance between the subwoofer and
the walls may help to smooth upper bass response in some rooms.
We recommend that you avoid placing a subwoofer near windows to prevent
rattling and sound transmission to the outside world.
If you are planning to install your SA600W inside a cabinet, please refer to the
guidelines on page 10.

PLACEMENT CONSIDERATIONS
e SA-600W is designed to be “built-in” friendly. All typically needed
controls are located on the front panel. An SA-600W can be easily integrated into
an equipment rack or custom cabinetry by following a few simple guidelines.
1) Allow adequate open space around the SA-600W’s side-mounted heatsinks for
adequate cooling. Also allow space behind the amp for connector clearance.
2) While the SA-600W generally runs only warm during spirited operation, we do
recommend that adequate heat vents are included in any custom cabinet which
encloses the SA-600W. A pair of 3 inch (7.5 cm) diameter vents near the bottom
of the cabinet and near the top of the cabinet, will allow cool air to circulate over
the heatsinks of your SA-600W keeping it cool and happy.
Rack Mount: e SA-600W ships with rack ears pre-attached for installation in a
standard 19-inch equipment rack.
Tabl e -Top: e SA-600W includes rubber feet for table-top installations.
Simply remove the hex screws that attach the rack ears to the SA-600W
and screw the rubber feet into threaded holes in the bottom of the amplier
case. WARNING: e rubber feet attach using M6-1.0 x 10mm screws. If
lost or misplaced, only replace with the same type and length of screws.
Using longer screws will cause damage to the internal circuit board.

FRONT PANEL CONTROLS IN DETAIL
Power Switch
e “Power” switch determines the operational readiness of the SA-600W and
should be the only method used to turn the amplier on and o. Do not use a power
strip switch, switched outlet or any other external switch as these may result in
undesirable and potentially damaging transient pops. Do not unplug the SA-600W’s
AC power cord while the unit is turned on.
The Power switch has three positions:
“o ”: e SA-600W is powered down. In this state, a negligible current draw
will exist for operating the main power relays. e front panel LED is RED and
the LCD Display is dim with the message “In Standby. Power switch is OFF.”
displayed.
“on”: e SA-600W is fully powered at all times. e front panel LED is GREEN
and the Home Screen menu options are listed on the LCD Display.
“auto”: In this position, the SA-600W can be activated by the following methods:
Signal Sensing: In this default mode, the SA-600W will power up when an audio
signal is present at any of its inputs and will power down its internal amplier
when no signal has been detected at its inputs for sixty (60) minutes. When
dormant, the SA-600W will draw a minimal amount of current (< 1 watt) to
power its Signal-Sensing circuitry. e front panel LED turns YELLOW when the
SA-600W powers down to indicate Standby mode and the LCD Display will show
“In Standby. Waiting for audio input.” e front panel LED will turn GREEN
when the SA-600W powers up.
Note: In the unlikely event that the auto Signal-Sensing feature is not sensitive
enough for a particular system, use a Y-adaptor cable (one female to two male
RCA-type connectors) to split the incoming signal into both RCA line inputs on
the SA-600W. is will increase the input sensitivity by 6 dB. Please be aware
that if there is signicant noise entering the inputs, the SA-600W may not turn
o as desired. If this happens, remove the Y-adaptor cable and/or look for the
noise source in the upstream components.

12V Trigger: Optionally, the SA-600W can be activated using a 12V DC signal.
To enable this mode, select “SYSTEM” on the Home Screen screen (see page 18
for more info) and select “12V ON”. is setting overrides audio Signal-Sensing
and will only turn on the SA-600W when a 12V DC signal is present at its
“12V Trigger - In” connection. When the 12V DC signal is removed from
the “12V Trigger - In” connection, the SA-600W will enter Standby mode
immediately, the front panel LED turns YELLOW and “In standby. Waiting for
12V trigger.” will be shown on the LCD Display.
Note: Whenever the SA-600W is ON, its “12V Trigger - Out” output will be
active, regardless of the “SYSTEM” setting. is allows you to control multiple
SA-600Ws using a single 12V trigger lead by daisy-chaining them together (“12V
Trigger - Out” activates the “12V Trigger - In” of the next amp, etc.).

CONNECTING YOUR SA-600W
Warranty void if serial number is removed, altered or defaced.
Warranty void if serial number is removed, altered or defaced.
Line Inputs
e SA-600W features individual le and right unbalanced RCA-type input
connectors. If you are connecting with a mono signal, use either the “L” or “R” input.
e SA-600W uses special isolation circuitry on the “LINE INPUTS” to mitigate
hum and noise in your system.
For the RCA connector, the tip is positive and the sleeve is negative. e input
impedance of the amplier is 50k ohms.
High Pass Outputs
e SA-600W features individual, le and right, unbalanced RCA-type output
connectors to feed a second amplier. ese outputs can be used in two distinct ways.
Crossover On: High-Pass Filtered Outputs
When the SA-600W’s onboard crossover is engaged, the “HIGH PASS
OUTPUTS” will deliver a high-pass ltered signal according to the frequency
and slope (12 or 24 dB per octave) congured in its crossover (XO) settings. is
output creates a true, two-way crossover between your subwoofer and main
stereo speakers. By removing low frequencies from the satellites, you
can create a seamless blend with your subwoofers, enhancing midrange
clarity and dynamics, with improved overall system response. is is
the correct way to add a subwoofer to your stereo system.
Note: You must supply separate le and right channel stereo inputs to the SA-
600W in order to have high-pass ltered, stereo outputs from its “HIGH PASS
OUTPUTS”. If you supply only one channel of input to the SA-600W, only the
line output corresponding to the input with signal will deliver a high-pass ltered
signal (the other line output will have no signal). If you are using two SA-600Ws
in a two-channel system, you can assign one SA-600W to the le stereo channel
and the other SA-600W to the right stereo channel, using only one “LINE
INPUT” and one “HIGH PASS OUTPUT” per SA-600W.
Crossover O: Pass-rough Outputs
When the SA-600W’s onboard crossover is defeated, the “HIGH PASS
OUTPUTS” will deliver a pass-through, buered signal that is identical to the
signal feeding the SA-600W’s “LINE INPUTS”. is is useful to feed other
equipment located nearby and most oen used in Home eater systems
where Bass Management is provided by the receiver or preamp/processor.

is feature is included for convenience when needing to connect the SA600W to a receiver that only oers speaker level outputs. It is not the preferred
method when a line-level signal is available.
To use this feature, simply connect the full-range speaker outputs of your
receiver to the “HIGH LEVEL INPUTS” plug of the SA-600W, in parallel with
the main speakers. In this application, the main speakers will remain full-range
and their sound will not be aected by the connection to the SA-600W.
e “HIGH LEVEL INPUTS” consists of an input connector and removable
plug with captured-wire receptacles. Standard speaker cable, up to 12 AWG (3
mm2), can be used and connected to the removable plug by backing out each set
screw, inserting the bare end of each speaker wire, taking care not to short any
wire to another, and tightening the set screw. Note: e mating connector is
keyed to t the input jack in one direction only.
“HIGH LEVEL INPUTS” connector (from le to right):
1. (-) Right Channel Negative
2. (+) Right Channel Positive
3. (-) Le Channel Negative
4. (+) Le Channel Positive
Input Impedance: 4.4 kΩ
Note: It is vital to observe correct electrical polarity of each channel’s
input signal. Failure to do so can result in no output, loss of signal and
poor performance.
Wireless JLINK™ Port
Your SA-600W includes a “WIRELESS JLINK™ PORT” receptacle that can be
used with a JL Audio JLINK™ TRX system (sold separately). e JLINK™ TRX is
a high-delity audio transmitter & receiver system, capable of wirelessly sending
audio signals up to 100 feet away (30 meters). Using a JLINK™ TRX will eliminate
the need to run physical signal cables from your receiver or preamp/processor’s
line-level outputs to the line-level inputs of your SA-600W. Instead, the SA-600W
will wirelessly receive audio signals into its “WIRELESS JLINK™ PORT” directly
from the JLINK™ receiver’s cable connection.
Note: Use of the JLINK™ TRX system requires line-level outputs from your
receiver or preamp/processor. Speaker level outputs are not compatible.

is feature is included to address signal grounding issues oen encountered
in home theater systems when several components from dierent manufacturers
are interconnected. e Input Mode switch on the rear connection panel
alters only the “LINE INPUTS” and is designed to facilitate a quiet, hum-free
connection to your audio or home theater system. is switch has no eect on
signals connected to the “HIGH LEVEL INPUTS”.
e SA-600W ships with this switch in the “Isolated” position. If, with all
system components connected and turned on (but no source material playing),
you hear a continuous low-frequency hum through your SA-600W, move this
switch to the “Grounded” position and evaluate the dierence in the noise level.
Use whichever switch position provides the least hum or noise. Note: If you
change equipment or add equipment to your audio system, you may need to
revisit the “Input Mode” switch setting to achieve the quietest signal path.
Subwoofer Outputs
e SA-600W is equipped with a pair of Neutrik speakOn® jacks for speaker
connections. Both jacks (labeled A & B) are congured for 2 wire termination
(speaker + & speaker –) and are connected in parallel, inside the SA-600W, so you
can use either output when connecting a single subwoofer.
A pair of removable Neutrik speakOn® plugs (NL2FX) are supplied with the SA600W for making high-integrity connections. Each plug is keyed for insertion in the
rear “SUBWOOFER OUTPUT” jacks in one direction only. Once inserted, rotate
the plug 1/8 turn clockwise to lock in place. To disconnect, slide the thumb latch
back and rotate the plug 1/8 turn counter-clockwise to remove. Receptacles in each
plug accept 12 AWG to 16 AWG speaker wire. Each wire attaches to the terminals
marked “1–“ and “1+” (shown below).
To attach wires, insert the speaker cable through the strain relief and chuck. Strip
½ inch (12 mm) of insulation from the end of each wire, then use a small Philips
screwdriver to back out the set screws. Insert the bare wire into the receptacle,
seating it rmly so that no bare wire is exposed. While holding each wire in place,
tighten the set screw rmly, taking care not to strip the head of the screw.
Note: Use caution to ensure correct polarity and wire placement.
Slide the strain relief and chuck over the speaker cable, up to the plug body.
Align the chuck with the recesses in the plug body and tighten the strain relief onto
the plug body.

To Remove - Unplug the SA-600W’s AC power cord. Insert a small athead
screwdriver into the cap’s slot and turn counter-clockwise slowly until the
fuse holder is released. Once removed, the fuse can be inspected and, if
necessary, replaced. Refer to the chart below for fuse values for your specic
SA-600W model.
To Reinstall - Note that the fuse holder’s body is keyed to the opening and
must be aligned to t properly. Insert the fuse holder into the opening and
gently turn clockwise (about 1/8 turn) to lock in place. Pressing the cap and
feeling for the spring to compress will help to locate the correct position.
Reconnect the AC power cord.
If the replacement fuse blows immediately aer replacing a fuse replacement,
the SA-600W may require service. Please contact your Authorized JL Audio
Retailer or Distributor.

Connector and make sure you are only powering the SA-600W from a receptacle
that matches these markings. Do not use any AC power cord other than the one
supplied with the SA-600W.
e SA-600W is a very powerful device and can draw a lot of current. If too
many components are connected with a SA-600W to one electrical outlet, you risk
tripping a household circuit breaker during very demanding program material.
If this happens, separate the SA-600W and other components between two AC
electrical circuits.

e “ELF” (Extreme Low Frequency) function allows the user to apply signal
equalization at 25 Hertz. You can cut the signal at 25 Hz by 12 dB or boost the
signal at 25 Hz by 3 dB (0.5 dB increments). At 0 dB the equalizer is set at for zero
contribution to the signal. At maximum boost, the signal at 25 Hz is increased by 3
dB.
e ELF Trim feature is useful for tailoring a subwoofer system’s low frequency
output for your particular room. Adding some boost can make certain material
more exciting. Using the cut function can help to compensate for room or boundary
gain in the low frequencies. Room boundaries and the room’s nite (limited) size
naturally cause very low frequencies to be boosted relative to other parts of the
signal. As such, using the ELF Trim feature to cut the lowest frequencies can help to
tame “bloat” or unnatural sounding low bass in small to medium sized rooms (and
can also reduce unwanted vibrations in the room or throughout the house).
e “ELF” function aects frequencies 2 to 3 times higher than the 25 Hz
specication. is frequency tapering eect may reduce the overall output of the
subwoofer and require the user to increase the “GAIN” control aer adjusting the

Connecting one SA-600W to a
Receiver via the High Level Inputs
e SA-600W features high level
inputs designed to accept the output
of an amplied source, such as a stereo
receiver’s speaker outputs. e use of this
feature is only recommended when no
suitable line-level signal is available.
When connecting a single SA-600W
in mono to a two-channel receiver’s
speaker outputs, you will use both the
Le and Right connections on the “HIGH
LEVEL INPUTS” plug of the SA-600W.
Use good quality speaker cables (up to 12
AWG/3 mm2) to make these connections.
Make sure you capture all the wire strands
in each connector port and do not allow
any of these wires to short together.
You can make the connections to the
SA-600W’s “HIGH LEVEL INPUTS”
at the receiver’s output terminals, or
at the main speakers, whichever is
more convenient. On receivers with
A/B speaker circuit selectors, you can
connect the SA-600W to the “B” outputs,
giving you the ability to easily switch the
SA-600W’s signal on and o with the
receiver’s speaker circuit selector switch.
e input section of your SA-600W
will sum the le and right inputs to mono
and you may use its onboard crossover

Note: It is vital to observe correct
electrical polarity of each channel’s
input signal. Failure to do so can
result in no output, loss of signal and
poor performance.

IMP ORTANT
STEREO SYSTEM SUBWOOFER SETUP
Once you have adjusted the controls on your stereo preamp and your
SA-600W to the above recommendations, you may apply the optional D.A.R.O.
(Digital Automatic Room Optimization) system to optimize performance.
Note: Use of the D.A.R.O. feature requires the optional JL Audio D.A.R.O.
Calibration Microphone (sold separately).
In some systems, the SA-600W amplier will be installed away from the
listening environment. For these cases, the D.A.R.O. microphone cable may
not be long enough to perform the Calibration.
To facilitate Calibration with the SA-600W amplier in the listening room,
a pair of alligator clips are included to connect to the subwoofer’s speaker
terminals. is will allow the user to temporarily connect the amplier to the
enclosure for Calibration, even aer the enclosure is permanently installed
in the wall cavity. To use, disconnect the enclosure’s speaker leads from the
subwoofer and use the alligator clips to connect the SA-600W’s outputs to the
subwoofer’s speaker terminals.
1) Applying Digital Automatic Room Optimization (D.A.R.O.)
You are now ready to apply the power of JL Audio’s exclusive Digital
Automatic Room Optimization (D.A.R.O.) system. is system will measure the
response of the subwoofer at your primary listening seat and apply a powerful
equalizer to tame the peaks caused by room modes, resulting in smoother, more
accurate bass performance.
IMPORTANT! MAKE SURE THE ROOM IS QUIET DURING D.A.R.O.
CALIBRATION! TURN OFF ANY NOISY APPLIANCES NEAR THE LISTENING
ROOM (DISHWASHERS, WASHING MACHINES, ETC.).
IT IS PARTICULARLY IMPORTANT TO TURN OFF AIR CONDITIONERS OR HEAT
PUMPS DURING CALIBRATION. THESE FORCED-AIR-TYPE HVAC SYSTEMS
CAN CREATE MODERATE LEVELS OF 15 – 20 HZ NOISE THAT MAY INTERFERE
WITH CALIBRATION.
a) Set the “Power” switch to the “on” position.
b) Remove the calibration microphone from its protective pouch and connect
its cable to the “MIC” jack on the SA-600W’s front control panel.
Note: D.A.R.O. Calibration is only possible when the JL Audio test
microphone is plugged in to the SA-600W front panel. e “Calibrate” feature
is disabled with no microphone plugged in to prevent accidental loss of
settings.
c) Connect the microphone to the other end of the mic cable and temporarily
place the mic in the primary listening seat. If you have a microphone stand,
you can place the microphone at head height and position in the primary
listening seat.
d) From the SA-600W’s User Interface, go to “DARO”, select “ON”, then
select “Calibrate”. A 5 second countdown will begin with “Position Mic”
displayed, indicating that the Calibration routine will begin in 5 seconds.
Page 29 | Fathom SA-600W
Page 30
e) Within 5 seconds of selecting “Calibrate”, return to your primary listening
seat and hold the microphone in your normal, seated head position at the
approximate height of your ears.
f) A low rumbling noise sequence will be played through the subwoofer
system that sounds like distant thunder. e sequence will last
approximately 3 minutes. During this process, the D.A.R.O. system is
taking a frequency response measurement at your seat and correcting
the problems it nds. e D.A.R.O. system also compensates for any
before & aer level dierences so that your subwoofer will have a similar
perceived loudness aer the calibration process. When D.A.R.O. is nished
calibrating, the “Calibrate” button will turn grey and the word “Calibrated”
will appear in green underneath, indicating a successful calibration.
To clear the D.A.R.O. settings (i.e., return them to at) & turn o the
“Calibrated” indication, select “Clear DARO”, then select “CONFIRM
CLEAR” to verify.
Should you wish to run a completely new calibration, simply repeat
Steps A-F. ere is no need to erase the old calibration rst. Any new calibration
will overwrite the existing data.
IMPORTANT! IF YOU MOVE YOUR PRIMARY LISTENING SEAT IN THE
FUTURE, YOU WILL NEED TO RUN D.A.R.O. AGAIN. ANY PARTICULAR
CALIBRATION IS UNIQUE TO THAT PARTICULAR SUBWOOFER POSITION
AND LISTENING SEAT POSITION COMBINATION.
2) Level Setting (GAIN)
Using familiar music material with deep bass content, adjust the subwoofer level
to blend with the other speakers using the Variable “GAIN” function on the SA600W. e subwoofer output level can be raised by up to 15 dB and can be attenuated
by 30+ dB, if needed.
We recommend starting with the bass level a little bit too low and then, carefully
raising the subwoofer output bit by bit until a perfect balance is achieved.
Inadvertently having the bass too loud (even a couple of dBs) can mask midbass detail.
3) Polarity
It is oen helpful to have a second person operating these controls so that you
can easily hear the changes from the primary listening seat.
Listening to familiar source material (preferably music with good upper bass and
midbass response), switch the “POLARITY” from “0 deg” to “180 deg” and listen for
dierences. is eect will be most noticeable in the small frequency region around
the crossover point. e correct setting will sound most natural with the best upper
bass punch and articulation. If both sound similar, choose “0”.

Page 31
4) DELAY (Phase) Adjustment
Now using the same music material, audition dierent “HP out DELAY” settings
and choose the delay that further enhances the upper and midbass response. Delay
is given in milliseconds.
When connected to a JL Audio subwoofer, we recommend starting with 10
milliseconds of HP out delay, which compensates for the small delay inherent in
the SA-600W’s built-in, box-correction EQ lter. Experiment with times just above
and below the 10 millisecond mark, perhaps up to approximately 14 milliseconds.
Choose the setting that most enhances the crossover region’s response (subwoofer
and satellite playing together).
If you cannot hear a dierence in the various “HP out DELAY” settings, leave the
control at 10 milliseconds.
5) ELF Adjustment (Extreme Low Frequency Trim)
Use the “ELF” control to adjust the extreme low bass extension of the SA-600W.
is control allows -12 dB of cut or +3 dB of boost at 25 Hertz and is particularly
useful when using a subwoofer (or two) in a small to medium sized home theater.
Since smaller enclosed spaces help to boost the level of the lowest bass frequencies,
smaller theaters can be overwhelmed by the strong low-bass output of the subwoofer.
is can create a “thick” or “bloated” character in the lower bass region. Turning
down the “ELF” cuts the extreme low bass level and alleviates this condition. Feel
free to experiment and listen to a variety of demanding material until you nd the
best match for your room and your tastes.
Your SA-600W is now optimized for maximum bass performance at your
preferred listening seat. Congratulations!

PREPARATION FOR HOME THEATER SETUP:
Please conrm the following system settings before beginning the setup
process. is will ensure a neutral starting point and an eective setup of your
subwoofer system. NOTE: In this Home eater setup process, we assume
that the receiver or processor is handling bass management tasks (see Step 1
below).
On your Home Theater Receiver or Processor:
Before beginning setup of your SA-600W, we recommend that you set your
receiver or preamp/processor as follows:
1. Speaker Size: In the speaker setup menu of your receiver or processor, set up
all of your high-frequency speakers as “small” with a crossover point of 80 Hz.
is will send ALL bass to the SA-600W.
2. Speaker Distance: In the speaker setup menu, properly set all speaker
distances to the primary listening seat, including the subwoofer’s distance. Use
a tape measure to determine these distances (time coherence is important.)
If multiple subwoofers are being used, average their distances to the primary
listening seat and use that number to set the subwoofer distance.
3. Subwoofer Level: Set the subwoofer level in the receiver or processor to “0” or
its middle position.
4. Tone Controls/Equalizers: Set all tone controls to “0” and defeat all equalizer
features.
On the SA-600W:
Before beginning the home theater setup procedure, ensure your SA-600W’s
controls are set to a neutral starting position.
1. Set GAIN to REF
2. Set POLAR to 0 deg
3. Set DELAY to OFF
4. Set ELF to OFF
5. Set XO to OFF (crossover function is handled by your receiver/HT processor)
6. Set EQ to OFF

HOME THEATER SUBWOOFER SETUP
Once you have adjusted the controls on your home theater receiver or preamp/
processor and your SA-600W to the above recommendations, you may apply the
optional D.A.R.O. (Digital Automatic Room Optimization) system to optimize
performance. Note: Use of the D.A.R.O. feature requires the optional JL Audio
D.A.R.O. Calibration Microphone (sold separately).
In some systems, the SA-600W amplier will be installed away from the
listening environment. For these cases, the D.A.R.O. microphone cable may
not be long enough to perform the Calibration.
To facilitate Calibration with the SA-600W amplier in the listening room,
a pair of alligator clips are included to connect to the subwoofer’s speaker
terminals. is will allow the user to temporarily connect the amplier to the
enclosure for Calibration, even aer the enclosure is permanently installed
in the wall cavity. To use, disconnect the enclosure’s speaker leads from the
subwoofer and use the alligator clips to connect the SA-600W’s outputs to the
subwoofer’s speaker terminals.
1) Applying Digital Automatic Room Optimization (D.A.R.O.)
You are now ready to apply the power of JL Audio’s exclusive Digital
Automatic Room Optimization (D.A.R.O.) system. is system will measure the
response of the subwoofer at your primary listening seat and apply a powerful
equalizer to tame the peaks caused by room modes, resulting in smoother, more
accurate bass performance.
a) Set the “Power” switch to the “on” position.
b) Remove the calibration microphone from its protective pouch and connect
its cable to the “MIC” jack on the SA-600W’s front control panel.
Note: D.A.R.O. Calibration is only possible when the JL Audio test
microphone is plugged in to the SA-600W front panel. e “Calibrate” feature
is disabled with no microphone plugged in to prevent accidental loss of
settings.
c) Connect the microphone to the other end of the mic cable and temporarily
place the mic in the primary listening seat. If you have a microphone stand,
you can place the microphone at head height and position in the primary
listening seat.
d) From the SA-600W’s User Interface, go to “DARO”, select “ON”, then
select “Calibrate”. A 5 second countdown will begin with “Position Mic”
displayed, indicating that the Calibration routine will begin in 5 seconds.
e) Within 5 seconds of selecting “Calibrate”, return to your primary listening
seat and hold the microphone in your normal, seated head position at the
approximate height of your ears.

f) A low rumbling noise sequence will be played through the subwoofer
system that sounds like distant thunder. e sequence will last
approximately 3 minutes. During this process, the D.A.R.O. system is
taking a frequency response measurement at your seat and correcting
the problems it nds. e D.A.R.O. system also compensates for any
before & aer level dierences so that your subwoofer will have a similar
perceived loudness aer the calibration process. When D.A.R.O. is nished
calibrating, the “Calibrate” button will turn grey and the word “Calibrated”
will appear in green underneath, indicating a successful calibration.
To clear the D.A.R.O.’s settings (i.e., return them to at) & turn o the
“Calibrated” indication, select “Clear DARO”, then select “CONFIRM
CLEAR” to verify.
Should you wish to run a completely new calibration, simply repeat the steps
above. ere is no need to erase the old calibration rst. Any new calibration will
overwrite the existing data.
IMPORTANT! MAKE SURE THE ROOM IS QUIET DURING D.A.R.O.
CALIBRATION! TURN OFF ANY NOISY APPLIANCES NEAR THE LISTENING
ROOM (DISHWASHERS, WASHING MACHINES, ETC.).
IT IS PARTICULARLY IMPORTANT TO TURN OFF AIR CONDITIONERS OR HEAT
PUMPS DURING CALIBRATION. THESE FORCED-AIR-TYPE HVAC SYSTEMS
CAN CREATE MODERATE LEVELS OF 15 – 20 HZ NOISE THAT MAY INTERFERE
WITH CALIBRATION.
2) Level Setting (GAIN)
Using familiar music or movie material with deep bass content, adjust
the subwoofer level to blend with the other speakers using your receiver or
processor’s subwoofer level control. is method is more immune to tampering
than using the SA-600W’s “GAIN” control (think toddlers or curious visitors).
In the unlikely event that the subwoofer level control in your receiver or
processor cannot be turned up enough to level match the SA-600W, return that
control to “0”. en, switch the SA-600W’s GAIN mode to VAR (Variable). With
“0” as your reference point (REF mode gain and VAR “0” gain are identical), use
the “VAR” control to level match the subwoofer with the other speakers.
3) POLARITY and DELAY (Phase) Adjustment
It is oen helpful to have a second person operating these controls so that you
can easily hear the changes from the primary listening seat.
Listening to familiar source material (preferably music with good upper bass
and midbass response), switch the “POLARITY” from “0 deg” to “180 deg” and
listen for dierences. e correct setting will sound most natural with the best
upper bass punch and articulation. If both sound similar, choose “0”.
Once “POLARITY” is set, use the same music material to audition dierent
“Sub out DELAY” settings and choose the one that further enhances the
upper and midbass response. Delay is given in milliseconds. Note that the HP
out control only applies to the “HIGH PASS OUTPUTS” on the rear panel
(not applicable if only a sub is connected to the SA-600W). If you can’t hear a
dierence in various “DELAY” settings, set the control to “0.”

TROUBLESHOOTING
No sound from subwoofer.
1. Verify that the SA-600W is plugged in, turned “ON”, with the Home
Screen menu options displayed on the LCD Display. If the SA-600W
will not power up, check the circuit breaker that feeds its outlet.
2. Verify that your receiver’s subwoofer settings have not changed.
3. If your other speakers play, but the connected subwoofer does not, try changing
the signal cables that feed the SA-600W or the speaker cables connecting the
subwoofer to the SA-600W.
4. If using the High Level Inputs, verify the correct electrical polarity of each
channel’s input signal.
5. A Protection Mode message appears on the LCD display if the SA-600W’s internal
temperature exceeds maximum levels. is built-in safeguard disables the output
signal to prevent damage to internal circuitry. Typical causes for this condition
are poor air circulation, likely due to conned mounting locations, and should be
corrected. Once the temperature decreases to normal levels, the Protection Mode
will deactivate and the SA-600W will automatically resume normal operation.
6. If the problem persists, contact your dealer or JL Audio Technical Support
for assistance.
Weak sound or poor performance when using the High Level Inputs.
1. Verify the correct electrical polarity of each channel’s input signal.
e bass level has changed.
1. Make sure your GAIN settings on the SA-600W and the level settings on your
receiver/preamp/processor have not changed.
2. Verify that the ELF TRIM setting has not changed.
Hums or other unusual noises from your subwoofer.
1. See Input Mode discussion on page 16 of this manual, especially if any upstream
components, cables, etc., have recently changed.
2. Turn o the SA-600W, disconnect all its input and output signal cables, turn the
SA-600W back on. If the noise disappears, the noise is being caused elsewhere in
your system - reconnect cables one at a time to help locate the problem.
Bass sounds “muddy” or “too heavy”.
1. Try decreasing the 25 Hertz level using the ELF Trim control. Muddy bass can
sometimes be caused by too much low frequency output in a moderately sized
room.
2. Decrease the overall subwoofer level.
3. Verify your receiver’s subwoofer settings.
4. Try a dierent main listening seat location. Changing your seating location can
have a HUGE eect on how your system sounds. See the placement discussion on
pages 6-9 of this manual.
