FLEXSYS MONITOR - FM series
DESCRIPTION
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
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.
FLEXSYS FM8
The FLEXSYS FM8 active coaxial stage monitor is
equipped with digital amplifier delivering 75W RMS for the
bass section and 25W RMS for the high frequency
section.
The speaker is equipped with 8" coaxial woofer (2" voice
coil) and 1" Neodymium driver (1" voice coil) loaded with
60°x60° 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).
FLEXSYS FM10
The FLEXSYS FM10 active coaxial stage monitor is
equipped with digital amplifier delivering 160W RMS for
the bass section and 40W RMS for the high frequency
section.
The speaker is equipped with 10" coaxial woofer (2" voice
coil) and 1" Neodymium driver (1" voice coil) loaded with
asymmetric 60°x90° horn.
The speaker is made 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.
