SR1530Z 3-WAY ACTIVE LOUDSPEAKER SYSTEM USER'S MANUAL IMPORTANT SAFETY INSTRUCTIONS 1. Read these instructions. 2. Keep these instructions. 3. Heed all warnings. 4. Follow all instructions. 5. Do not use this apparatus near water. 6. Clean only with dry cloth. 7. Do not block any ventilation openings. Install in accordance with the manufacturer's instructions. 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. 10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. 11. Only use attachments/accessories specified by the manufacturer. 12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. PORTABLE CART WARNING Carts and stands - The Component should be used only with a cart or stand that is recommended by the manufacturer. A Component and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the Component and cart combination to overturn. 13. Unplug this apparatus during lightning storms or when unused for long periods of time. 14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as powersupply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. 15. This apparatus shall not be exposed to dripping or splashing, and no object filled with liquids, such as vases, shall be placed on the apparatus. 16. This apparatus has been designed with Class-I construction and must be connected to a mains socket outlet with a protective earthing connection (the third grounding prong). 17. This apparatus has been equipped with an all-pole, rocker-style AC mains power switch. This switch is located on the rear panel and should remain readily accessible to the user. 18. This apparatus does not exceed the Class A/Class B (whichever is applicable) limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications. ATTENTION -- Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant las limites applicables aux appareils numériques de class A/de class B (selon le cas) prescrites dans le réglement sur le brouillage radioélectrique édicté par les ministere des communications du Canada. 19. Exposure to extremely high noise levels may cause permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S. Government's Occupational Safety and Health Administration (OSHA) has specified the permissible noise level exposures shown in the following chart. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. To ensure against potentially dangerous exposure to high sound pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels use hearing protectors while the equipment is in operation. Ear plugs or protectors in the ear canals or over the ears must be worn when operating the equipment in order to prevent permanent hearing loss if exposure is in excess of the limits set forth here.

The SR1530z is a high-efficiency, extreme output, horn-loaded, 3-way, wide-dispersion, active sound reinforcement system. It features a one-piece 90º x 40º horn, which includes both the mid- and high-frequency sections in a proprietary optimized WavefrontTM design. Unlike typical mid/high horn designs, the high-frequency section is positioned to fire down into the 6-inch midrange's dispersion pattern. This creates a focused, single wave front with excellent phase and power response characteristics. The resulting 90º x 40º dispersion pattern provides a very open, natural sound at extreme output levels. The 6-inch neodymium mid-range transducer operates between 700 Hz and 3000 Hz, eliminating the placement of a crossover point in the middle of critical voice frequencies. Frequencies above 3000 Hz are reproduced by a 1-inch neodymium compression driver. The low frequencies are produced by a high-output 15-inch woofer with a X-inch high-temperature voice coil. Connecting and setting up the SR1530z is a breeze. It accepts a line-level signal via a female XLR input jack. A male XLR Thru jack is provided for daisy-chaining the signal to additional SR1530z cabinets. Three built-in power amplifiers provide 100 watts rms each for the mid-frequency and high-frequency drivers, and 300 watts rms for the low-frequency driver. The amplifier modules sit on a mammoth aluminum heatsink that eliminates the need for fans. A tremendous benefit of having the amplifiers located within the loudspeaker cabinet is that the SR1530z functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value. The rear mounted amplifier assembly features: · an input XLR and loop-through XLR · Power ON indicator · Protection indicator The cabinet is constructed using both 18 mm multilayered plywood and pressure injected structural resin. A carrying handle is integrated into each side for easy loading and transport.

MAIN INPUT This is a female XLR-type connector that accepts a balanced line-level signal from a mixing console or other signal source. 6. AC Receptacle This is where you connect the AC linecord to provide AC power to the SR1530z's built-in power amplifiers. Plug the linecord into an AC socket properly configured for your particular model. 2. LOOP OUT This is a male XLR-type connector that produces exactly the same signal that is connected to the MAIN INPUT jack. Use it to daisy-chain several SR1530z's together off the same signal source. MAIN INPUT 3. Power ON Indicator When the POWER switch is turned on, and the linecord is connected to an active AC power supply, this indicator lights green to let you know that you're ready to rock and roll. The cool blue LED on the front of the cabinet works in the same way. LINE LEVEL SIGNAL PARALLEL LOOP OUT 4. PROTECTION Indicator The SR1530z has a built-in limiter that prevents the amplifier outputs from clipping or overdriving the transducers. The PROTECTION indicatior lights when the limiter is activated. It's okay for the PROTECTION indicator to blink occasionally, but if it blinks frequently or lights continuously, turn down the signal source's level control until the PROTECTION indicator only blinks occasionally. There is also a thermal protection circuit that monitors the internal temperature of the amplifiers and heatsink. If the temperature should exceed a safe operating level, this indicator lights and the signal is muted to allow the amplifiers to cool. When the temperature cools to a safe level once again, the thermal protection circuit deactivates and normal operation continues. Note: Activation of the thermal protection circuit is an indication that you should take steps to avoid continued thermal problems. See "Thermal Considerations" on page 6.
