AC POWER REQUIREMENTS Acoustic Components AC POWER The EX1.2’s woofer technology is based around high efficiency, high power woofer designs. The device features: high temperature polymide voice coil assemblies that undergo multiple baking and curing processes as well as advanced magnetic structures with complex cooling systems. The woofer cones have been specially developed to withstand the demanding environment created by the high acoustic loading inside the EX1.2 chambers. The EX1.
AC POWER REQUIREMENTS Make sure that even with the AC voltage drop, the AC voltage always stays within recommended operating ranges. The minimum electrical service amperage required by a EX1.2 speaker system is the sum of each loudspeaker’s maximum continuous rms current. An additional 50 percent above the minimum amperage is recommended to prevent peak volt-age drops at the service entry. The Power Connector The EX1.2 requires a grounded outlet.
AC POWER REQUIREMENTS IMPORTANT SAFETY INSRUCTIONS SAFETY SUMMARY 1. Read all product instructions. To reduce the risk of electric shock, disconnect the loudspeaker from the AC mains before installing audio cable. Reconnect the power cord only after making all signal connections. Connect the loudspeaker to a twopole, three-wire grounding mains receptacle. The receptacle must be connected to a fuse or circuit breaker.
EX1.2 CONTROL PANEL REAR CONTROL PANEL The EX1.2 features an easy to use rear control panel featuring audio input and output connections, level control, LED status lights and a phase switch, that changes the phase of the high pass audio output signal. This serves as a tool for integrating the full range cabinet and the subwoofer into challenging audio environments. Audio signal can be daisy-chained using the through output connector on the input panel. A single source can drive multiple EX1.
EX1.2 CONTROL PANEL Amplifiers and Acoustic Filters Phase Switch A power amplifier specifically designed and optimized for the low frequency woofer powers the EX1.2 . The control system in the EX1.2 processes the audio signal through a series of electronic filters and circuits providing equalization, crossover filters, thermal and overdrive protection. The EX1.2 features a phase switch that changes the phase of the high pass audio output signal.
