A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.
- Protect the power cord from being walked on or pinched, particularly at plugs, receptacles, and the point where they exit from the apparatus.
- Only use attachments/ accessories specified by the manufacturer.
- Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution whenmoving the cart/apparatus combination to avoid injury from tip-over.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug isdamaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, orhas been dropped.
- If referring to service instructions in this manual: CAUTION! – These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock do not perform any servicing. Other than that contained in the operating instructions unless you are qualified to do so.
- Important Warning – The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.
- Electromagnetic Compatibility – The speaker has good electromagnetic shielding and good electromagnetic compatibility but the speaker inside has high magnetism, it may affect your TV, Computer, and other electronic products, so when in use keep away from these items. The controller also has electromagnetic radiation and infrared radiation when in use, so the same applies.
- To completely disconnect this apparatus from the AC mains, disconnect the power supply cord plug from the AC receptacle.
- Warning! To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
- Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment.

SECTION 2: PRECAUTIONS
Do not under any circumstances operate the unit with an AC power supply less than 110V or greater than 220V. Doing so may result in serious damage to your speaker system which will not be covered by a warranty.A robust AC supply is necessary for maximum performance. If the supply is too weak the bass performance may be affected and if it sags (drops) too much the system may self-mute to protect itself. As soon as the appropriate AC supply is restored it will continue to operate. Plugging multiple systems into the same outlet and long extension cord runs may affect the AC supply to the systems.CAUTION!In compliance with safety agency criteria and proper system operation, it is critical that the system installer observe all electrical safety practices at all times and provide proper earth grounding for all AC power connections.
POWER AMPLIFIERS – OPERATING TEMPERATUREThe design of the amplifier is such that it is very energy efficient and as a result does not get extremely hot. In the rare event that it does get too hot it will automatically shut down to protect itself. When its temperature has returned to within its operating range it will turn back on. A condition under which this may occur is when the system is operated in very high ambient temperatures and the heat sink on the rear of the enclosure is in direct sunlight. Always ensure adequate cooling and appropriate shade
CARE & MAINTENANCE
While your speakers are rugged and will provide years of service, some common sense care in handling will prevent damage and preserve appearance.
- If your speaker will be frequently moved, consider a padded carrying bag.
- If your speakers have been subjected to prolonged exposure to extremely low temperatures, avoid subjecting them to heavy mechanical shock and warm thespeakers up by playing at a low volume for one hour before playing at loud levels.
- Keep the exterior of the speaker enclosure clean. Clean only with a dry cloth.
- The speakers are not intended for fixed installation in outdoor environments.Moisture can damage the speaker cone and surround, cause corrosion of electrical contacts, and create an electrical shock hazard. Protect your speakers from moisture avoid exposing the speakers to direct moisture. Any electrically powered device can produce dangerous shock hazards when wet or exposed to moisture. Keep speaker out of extended or intense direct sunlight. The driver’s integrity may be affected and finished surfaces will be degraded by long-term exposure to intense ultra-violet (UV) light.This apparatus contains potentially lethal voltages. To prevent electric shock or hazard, do not remove chassis, input module or AC input covers. No user-serviceable parts inside. Refer servicing to qualified service personnel.
MOUNTING/SUSPENDING SPEAKERS
The speakers are designed for portable applications in which the speakers will be stacked directly on the floor, stage, speaker stands, or a solid, stable platform.When placed on a smooth surface such as polished wood or linoleum, the speakers may move due to acoustical energy output. Precautions should be taken to assure that the speaker does not fall off the stage or table on which it is placed. Optional accessory items are available from professional and after-market suppliers to facilitate the suspension and wall/ceiling mounting of the speakers. Only those items recommended by professionals should be used. When using these items, review all enclosed documentation and carefully follow all instructions and safety precautions.
CAUTION! Suspension of speakers should be done by qualified persons following safe rigging standards and practices. Unsafe mounting or overhead suspension of any heavy load can result in serious injury and equipment damage.CAUTION! When suspending this product carefully follow the instructions and local ordinances. Do not attempt to use unless you have read and understood all instructions including the user’s guide. Attachment of the loudspeaker to a supporting structure should be referred to a qualified professional.

- Refer to the control panel.
- Turn the controls fully counter-clockwise.
- Set the MIC/LINE switch:• If a microphone will be connected directly to MIC1 or MIC2, set the MIC/LINE switch to the MIC position(depressed). The MIC LED will illuminate when the power is turned on.• If a mixer, CD player, cassette tape, or electronic musical instrument (the “source”) will be connected directly to MIC1 or MIC2, set the MIC/LINE switch to the LINE position (disengaged).
- Plug the power cable into a properly grounded 3-wire AC power outlet.
- Plug the XLR cable from the mixer or microphone into the MIC1 or MIC2 connector.
- Connect other sources (if used) to the LINE 1 and LINE 2 input connectors.
- Power-Up Procedure:The main power switch is located on the input panel on the back of the enclosure. Always ensure that the speaker system is the last thing you power-up, and the first thing to turn off when operating your complete PA system. If speaker systems are daisy-chained together always turn off the last system in the chain first. Power “on” is indicated by the illumination of the logo on the front of the enclosure and the power “on” LED.• First, switch on the power switch.• Next, turn on the power switch.• Reverse this process when shutting down your system.
- Set Volume• If you are using an audio mixing console, refer to the manufacturer’s instructions to properly set the gain structure.• Turn up your sources to the level that will be used in performance and talk, sing or play into the system.• Bring the MIC1 or MIC2 control up (clockwise) until the desired volume has been reached, If you are using a microphone, turn the MIC1 or MIC2 control up slowly to avoid feedback.
- Check the limit LED• The limit indicator flashes when the loudspeaker’s onboard amplifiers are approaching maximum output. Occasional flashes are normal for very loudoperations. However, if the LIMIT LED stays illuminated, the sound may be distorted and it is an indication that more speakers or a lower performance volume may be required for your specific application.

- Before using a microphone, first, adjust the volume to the low, then connect the microphone to the 6.35 socket or XLR socket. This speaker can accept 1-2 microphones. When using microphones, adjust the microphone volume and also adjust the background signal volume. Pay attention to avoid signal feedback and cause squeaking.
- After use, cut off the power of the router signal and remove the SD Card or MP3. Turn the volume, signal PWL and microphone volume to low, then cut off the power to the amplifier.
- If a long time with no use has passed, it is safe to pull off the power of the amplifier.
SECTION 5: LOUDSPEAKER PLACEMENT & SUSPENSION
The following guidelines will help you achieve optimum sound wherever you use your loudspeakers.Raise the speakers as high as possible.For the best results, try to get the high-frequency horn at least 2-4 feet above the heads of the audience. If the speakers are too low, the people in the back of the audience will not receive the best-qualified sound.Place the speakers between the microphones and the audience.Feedback occurs when the microphones pick up sound from the speakers and “feeds” the sound back through the sound system. If space is limited, point the speakers away from the microphones to reduce feedback.Locate the speakers away from turntables.Low-frequency feedback occurs when the output of the speaker is picked up by the tonearm of the turntable and is re-amplified. A heavy, solid turntable base and shock mounting can also reduce this type of feedback in DJ applications.Use more speakers in large or highly reverberant spaces.Spreading speakers throughout these spaces will produce much better sound than trying to compensate with loudness level or equalization. For very long distances, the use of another set of speakers with time delay is recommended.Stand speakers upright for PA – Tilt the speakers back on the side for stage monitoring. Upright stance provides even coverage over a wide area. The speakers are also designed with two slanted positions for stage monitoring applications.Using the suspension points.Caution! Suspension of the speakers should be done by qualified persons following safe rigging standards and practices. Unsafe mounting or overhead suspension of any heavy load can result in serious injury and equipment damage.Caution! When suspending this product carefully follow instructions and local ordinances. Do not attempt to use unless you have read and understood allinstructions including the User’s Guide. Attachment of the loudspeaker to supporting structure should be referred to a qualified professional.Caution! Do not suspend the speaker from the pull-back point. Before suspending the system, inspect all components involved for cracks, deformations, corrosion, and/or missing or damaged parts that could reduce the strength and safety of the installation.
- Remove suspension point caps.
- Insert load-rated shoulder eyebolt with washer and tighten appropriately. Never suspend more than one speaker system from its suspension points.
