DESCRIPTION
The SIGMA series is an active speakers line, with digital multiamplification composed by
two speakers and one subwoofer. Sigma S115, woofer 15” and 1,4” driver, Sigma S215,
double woofer 15” and 1,4” driver, Sigma S118 subwoofer with 18” woofer.
SIGMA series speakers are realized with Hybrid Enclosure Technology (H.E.T.),
developed in the dB Technologies labs. The box in fact is made in light multilayer wood,
coated in PVC with protection frames on top and bottom in polypropylene.
®
The speakers of SIGMA series use digital amplifiers DIGIPRO G2 of last generation,
power supplies featuring switching SMPS (Switched-Mode Power Supplies) technology
which can delivering 1000W and 1400w to satisfy each kind of application.
These highly efficient amplifiers provide high power with limited weight. Thanks to the low
power dissipated, the cooling of the amplifier module does not require a fan.
The digital preamplifier with DSP (Digital Signal Processor) controls the audio crossover
of the acoustic components, the frequency response, the limiter, and the acoustic phase
alignment.
In the S115 and S215 speakers, a selector placed on commands panel, enables to select
one of two different equalizations, “FLAT” and “BOOST“, to guarantee high versatility for
the different applications.
In the S118 subwoofer, selector placed on commands panel, enables to select between
two acoustic crossover frequencies: “80Hz” and “100Hz“.
SIGMA S115
The S115 bi-amped active speaker is equipped with a
®
DIGIPRO G2 amplifier delivering 1000W .
S115 is a two-way speaker, with woofer 15” (voice coil 3”) and
compression driver 1,4” (voice coil 2.84”) on a 60°x40°
aluminium CD-horn.
The speaker’s horizontal directivity is 60° by default factory
setting.
The speaker is made of 15mm light multilayer wood, coated in
PVC with protection frames on top and bottom in
polypropylene; the two handles located on the sides of the
speaker enabling easy transportation.
In the bottom of the box there is a standard pole mount cup
(D36mm) made of aluminium and a retractable adjustable
foot (in height) to inclinate the tilt angle up to a max. of 7°. This
allows to direct the sound radiation without using additional
supports.
SIGMA S215
The S215 bi-amped active speaker is equipped with a
®
DIGIPRO G2 amplifier delivering 1400W .
S215 is a quasi 3 way typology speaker, with two woofers 15”
(voice coil 3”) and compression driver 1,4” (voice coil 2.84”)
on a 60°x40° aluminium CD-horn.
The speaker’s horizontal directivity is 60° by default factory
setting.
The phase plug attached to the front of the upper woofer
avoids the vertical phase modulation which usually take place
in this type of configuration and ensures a precise horizontal
coverage of the medium frequencies.
