dBTechnologies FM 12 Active Stage Monitor with 12" Woofer

The FLEXSYS FM 12 active coaxial stage monitor is equipped with digital amplifier delivering 240W RMS for the bass section and 60W RMS for the high frequency section. The speaker is equipped with 12” coaxial woofer (2” voice coil) and 1” Neodymium driver (1,3” voice coil) loaded with asymmetric 60x90 degree horn. The speaker is realized with hybrid technology H.E.T. (Hybrid Enclosure Technology): box made in lighter plywood PVC coated, sides in polypropilene, and is provided with a handle, on bottom side, which eases transportation. In the left side of box there is a standard pole mount cup (D36mm).

The coaxial stage monitors of the “FLEXSYS FM” series are low profile loudspeakers realized with Hybrid Enclosure Technology (H.E.T.), developed by the dB Technologies labs. The box in fact is made in light multilayer wood, coated in PVC and the sides are in polypropylene. The coaxial stage monitors of the “FLEXSYS FM” series use multichannel digital power amplifiers of last generation DIGIPACK . These highly efficient amplifiers provide high power with limited weight and dimension. Thanks to the low power dissipated, the cooling of the amplifier module does not require a fan. The digital preamplifier with DSP (Digital Signal Processing) controls the audio crossover of the acoustic components, the frequency response, the limiter, and the phase alignment. The correct switch on of the amplifier is guaranteed by an initialization procedure; during this test stage the LEDs (“LIMITER” and “ON SIGNAL”), located on the amplifier module, stay on together for approx. 2 sec. At the end of the switch on procedure, on the amplifier module, the “ON SIGNAL” green LED flashes slowly, when there is signal absence. During normal operation the “ON SIGNAL” green LED serves as Vu-meter monitoring the audio level riproduced. The "LIMITER" red LED lights up to indicate that the internal limiter circuit has tripped to prevent amplifier distortion and protects the speakers against overloads.
