Descriere The DYNACORD FX 12 is concepted as a medium longthrow mid/high- frequency cabinet in coaxial design. It can be used also without subwoofer cabinets in high-quality sound reinforcement system for speech for medium-throw distances. The recommended active x-over frequency is 140 Hz, 18 dB/oct. Butterworth. In the lo-mid range an ND 12 A Electro-Voice loudspeaker chassis works into a conical horn. The 80x40 Constant Directivity horn, driven by an Electro-Voice 1.4" ND 6 neodymium driver delivers the frequency range above 1kHz. The FX 12 is equipped with a passive x-over (1kHz, 18 dB/oct). Every transducer is protected against thermal overload with an electronic circuit called VOICE COIL TRACKING PROTECTION. This circuit senses the terminal voltages of the transducers and simulates the thermal behaviour of the tranducers" voice coils. In case of a potential thermal overload the power applied to the speakers is reduced to a safe level. Power amps up to 1200W 8 Ohms can be used in order to have maximum dynamic range without the danger of thermal overload in non-controlled situations. The VOICE COIL TRACKING PROTECTION exhibits "soft" switching characteristics, so no annoying clicks or pops are audible. The circuitry automatically resets after the voice coil temperature has reached a safe value. Specificatii tehnice
