[. . . ] SbA760 User Manual Electro-Voice® SbA760 User Manual Important Safety Instructions The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" 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 appliance. 1. Do not expose this apparatus to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on this apparatus. Do not block any of the ventilation openings. Install in accordance with the manufacturers instructions. [. . . ] 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 SbA760 provides outstanding performance even under most demanding conditions. The SbA760 is also especially suitable for many rental applications. Compared to Class-AB-operated amps and because of utilizing Class-H High-Efficiency 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® EVS-15FR 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 SbA760 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 SbA760 can be easily integrated into any existing sound reinforcement installation. Unpacking and Warranty Open the packing and carefully take out the SbA760. Remove the protective foil from the carrying handles. A power cord and the warranty card are supplied in addition to this owner's 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 SbA760 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 subwoofer's rear during operation. Otherwise, the SbA760 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 Neutrik's professional "PowerCon" connector system and by use of an 15' (5m) AC cord. This ensures an absolute secure and reliable power supply connection. However, with large installations consisting of several active cabinets, the use of high-quality AC distributors that allow high power consumption and offer reliable protection throughout the entire system is strongly recommended. Before establishing the AC connection for the first time, make sure that the SbA760's operation voltage setting, which can be found on a label next to the AC switch, corresponds to your local AC voltage. 1 Electro-Voice® SbA760 User Manual 1. [. . . ] If the AC cord is correctly connected and the AC switch does not light upon power-on, please contact your local dealer. Mains (AC) Fuse During normal operation the mains (AC) fuse of the SbA760 only blows at the occurrence of a malfunction. Exchanging the fuse is only permissible using a fuse of the same type (current, voltage and release characteristic). In case the fuse blows frequently, please contact your local dealer. [. . . ]
