In buying an Electro-Voice® SbA760 you decided on getting one of today's most advanced active subwoofers incorporating sophisticated technology. The active 15" subwoofer SbA760 with integrated 760 watt power amplifier has been specially designed to provide fundamental bass support for professional full-range and multi-channel cabinets. AC power is supplied via the Neutrik's professional "PowerCon" connector system and by use of an 15' (5m) AC cord. 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. Quick Start Caution: Before switching on the power of the SbA760 always set the LEVEL control to its counterclockwise stop. A playing sound source could otherwise lead to extreme output levels. This Quick Start Manual outlines the set up and operation of a SbA760 used as add-on subwoofer together with a Powermixer (see configuration examples). Set up your Powermixer system as usual and connect a signal source to the power mixer (e. g. Set the SbA760's LEVEL control to its counterclockwise stop and connect the unit to a wall outlet using the supplied PowerCon mains cord. Use a stereo phone plug cable to connect the Powermixer's MONO OUT to the SbA760's L/MONO INPUT. When switching off your equipment, please proceed in the opposite order, i. e. Set the SbA760's LEVEL control to its center position (0dB) and start the playback of the desired signal audio source. After adjusting the desired acoustic output level of the full-range cabinets using the Powermixer's master fader, establish volume setting for the subwoofer using the MONO OUT fader.
