[. . . ] The integrated High-Efficiency 750W power amplifier optimally matches the DL15Y woofer offering highest dynamic and audio performance and ensures at the same time that the DL15Y woofer is always operated in its optimum operation range. Extensive protection circuitry like VCP, DC/HF-protection, audio limiter, Back-EMF protection and thermal protection are employed to securely monitor the compliance to these operation limits guaranteeing that the SbA750 provides outstanding performance even under most demanding conditions. The SbA750 is also especially suitable for many rental applications. Compared to Class-AB-operated amps and because of utilizing Class-H HighEfficiency technology the power amplifier produces significantly less power loss, and additionally reduces thermal stress of all components. Employing fans to ensure thermal stability is not necessary because of the Class-H technology and use of comprehensively dimensioned cooling profiles. The enclosure is sealed with extremely durable Futura coating and a robust powder-coated steel grille provides protection for the Electro-Voice® DL15Y woofer against mechanical damage. All controls and the cooling profiles of the power amp module are recessed to provide optimum protection for the sensitive parts of the SbA750 even during transportation. Two carrying handles, four castors and an integrated threaded pole-mount stand flange allow comfortable transportation and optimum, space saving installation. Because of its versatility, the SbA750 can be easily integrated into any existing sound reinforcement installation. Unpacking and Warranty Open the packing and carefully take out the SbA750. Remove the protective foil from the carrying handles. A power cord and the warranty card are supplied in addition to this owners manual. Please make sure that all details are filled in on the warranty card. Only a completely filled in warranty certificate entitles you to stake any warranty claims. Therefore, keep the original invoice together with the warranty certificate at a safe place. Setup and Connections Place the SbA750 on an even ground if possibly by using the supplied rubber feet to ensure safe operation. Make sure to check the stability of the system when using pole-mount stands. Do not cover the heat sink on the subwoofers rear during operation. Otherwise, the SbA750 will enter protection mode because of thermal overload. Although this provides reliable protection for the subwoofer, sound reproduction is muted until the normal operation mode is regained. AC power is supplied via the Neutriks professional PowerCon connector system and by use of an 15 (5m) AC cord. This ensures an absolute secure and reliable power supply connection. [. . . ] The switch lights after turning the power ON. Make sure that the AC cord is correctly connected if the switch is not lit upon turning the power on. If the AC cord is correctly connected and the AC switch does not light upon power-on, please contact your local dealer. AC Fuse During normal operation the AC fuse of the SbA750 only blows at the occurrence of a malfunction. [. . . ]
