“dangerous voltage” within the product’s enclosure, and may be of sufficient magnitude to constitute a risk of electric
shock.
The exclamation point triangular symbol is intended to alert the user to the presence of important operating and
maintenance (servicing) instructions in the user manual accompanying the unit.
CAUTION
RISK OF ELECTRIC SHOCK! DO NOT OPEN!
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE THE COVER (OR BACK). THERE ARE NO
USER SERVICEABLE PARTS INSIDE. REFER SERVICE TO YOUR AUTHORIZED AMERICAN AUDIO® SERVICE

Cart – A product and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may
cause the product and cart combination to overturn.
Location – The appliance should be installed in a stable location.
Nonuse Periods – The power cord of the appliance should be unplugged from the outlet when left un- used for a long period of time.
Grounding or Polarization
If this product is equipped with a polarized alternating current line plug (a plug having one blade wider than the other), it will fit into the
outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug
should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug.
If this product is equipped with a three-wire grounding type plug, a plug having a third (grounding) pin, it will only fit into a grounding type
power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete
outlet. Do not defeat the safety purpose of the grounding type plug.
Outdoor Antenna Grounding – If an outside antenna or cable system is connected to the
product, be sure the antenna or cable system is grounded so as to provide some
protection against voltage surges and built-up static charges.
Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with
regard to proper grounding of the mast and supporting structure, grounding of the leadin wire to an antenna discharge unit, size of grounding conductors, location of antennadischarge unit, connection to grounding electrodes, and requirements for the grounding
electrode.

For adult use only - Keep out of the reach of children.
Be sure all power is turned off before making subwoofer connections.
Do not remove the protective grills under any conditions.
Always use a power cord that meets the manufactures exact power specifications.
Disconnect from main power before making any type of connection.
To reduce the risk of electrical shock or fire, do not expose this unit rain or moisture.
Always mount the speakers in a safe and stable matter.
Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon
or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the device.

6. CONTROLS AND FEATURES
©American Audio® - www.americanaudio.eu
PXW 18P
User Manual Page 16
6.1 SUBWOOFER REAR PANEL
(1) Limit Indicator – The Limit Indicator will blink on occasion when built-in limiter is active.
NOTE: If the indicator glows or starts to blink frequently, you should turn down the subwoofer level.
(2) Signal Indicator– The Signal Indicator will glow when there is a signal received to the full range input.
(3) Subwoofer Gain Control – This knob is used to regulate the output level of the subwoofer. Use this to set the balance between the speakers
and subwoofers.
(4) Protect Indicator – The protect indicator will begin to glow when the subwoofer goes into protect mode. Protect mode prevents the
subwoofer amplifiers from getting too hot. When the subwoofer goes into protect mode all output will stop. This is to protect the subwoofer and
any speakers connected to the subwoofer.
(5) Power LED – This LED will be lit when you switch on the power.
(6) High Pass XLR Output – These outputs are used to send the incoming signal to a full range active speaker or power amp.
(7) Phase Switch – The phase switch reverses the polarity of the subwoofer. This switch depends on the placement of the subwoofer relative to
the speakers. Experiment with the switch and positions of the subwoofer and speakers to find the best sound.
(8) Full Range XLR Input – These connections are designed to accept a line input signal from a mixer or other line level device with a balanced
output jack. Use a balanced cable when the signal cable length exceeds 15 feet, this will reduce excessive signal loss. Be sure to connect only line
level input devices such as mixers to these inputs.
(9) THRU (Full Range Output) – These outputs are used to send the signal from the full range inputs to another device.

8. ROHS – A GREAT CONTRIBUTION TO THE CONSERVATION OF ENVIRONMENT
The European Union has adopted a directive on the restriction / prohibition of the use of hazardous substances. This directive, referred to as
ROHS, is a frequently discussed topic in the electronic industry.
It restricts, among other things, six materials: Lead (Pb), Mercury (Hg), hexavalent chromium (CR VI), cadmium (Cd), polybrimated biphenyls as
flame retardant (PBB), polybrominated diphenyl, also a flame retardant (PBDE). The directive applies to nearly all electronic and electrical devices
whose mode of operation involves electric or electromagnetic fields – in short: each kind of electronics we have around us in our households or at
work.
As manufacturers of products of the brands of AMERICAN AUDIO, AMERICAN DJ, ELATION Professional and ACCLAIM Lighting, we are obligated to
comply with the RoHS directive. Therefore, as early as two years prior to the directive coming into force, we started our search for alternative
environmentally friendly materials and manufacturing processes.
Well before the RoHS directive took effect, all of our products were manufactured meeting the standards of the European Union. With regular
audits and material tests we can still assure that the components we use are always RoHS-compliant and that the manufacturing process, as far as
the state of technology allows, is environmentally friendly.
The ROHS directive is an important step to the protection of our environment. We, as manufactures, feel obligated to make our contribution in
this respect.

9. WEEE – WASTE OF ELECTRICAL AND ELECTRONIC EQUIPMENT
Every year thousands of tons of electronic components, which are harmful to the environment, end up at the waste disposals around the world.
To ensure the best possible disposal or recovery of electronic components, the European Union has adopted the WEEE directive.
The WEEE-system (Waste of Electrical and Electronic Equipment) can be compared with the system of the “Green Spot”, which has been in use for
several years. The manufactures have to make their contribution to the utilization of waste at the time they release the product. Money resources
obtained by doing so will be applied to develop a common system of waste management. Thereby we can ensure professional and
environmentally friendly scraping and recycling program.
As manufactures, we are part of the German system of EAR and we make our contribution towards it.
(Registration in Germany: DE41027552)
That means that products of AMERICAN DJ and AMERICAN AUDIO can be left in the collection points free of charge and they will be used in the
recycling program. Products of ELATION Professional, which are used only by professionals, shall be handled by us. Please send Elation products
directly to us at the end of their lifetime so that we can professionally dispose of them.
Like the above ROHS, the WEEE directive is an important contribution to the environment protection and we are glad to help to clean the
environment with this disposal system.
We are happy to answer any of your inquiries and welcome your suggestions at: info@americandj.eu
