Compact High-Power Curvilinear Array
MICA™ is a self-powered, three-way loud-
speaker designed for vertical curvilinear
arraying. A member of the MILO
high-power curvilinear array loudspeakers,
the MICA loudspeaker is ideal for applications
that do not require quite as much power and
throw distance as MILO and where weight and
size is a concern. The MICA compact high-
power curvilinear array loudspeaker is equally
applicable in a wide variety of applications
such as touring, rental and fixed installations.
MICA provides an excellent complement to a
MILO main system for tours that are playing
a variety of venues, being used as sidefills
for large arenas and sheds and as the main
system for smaller venues.
The loudspeaker provides very high acoustic
output, with a single MICA producing a peak
output of 138 dB SPL at one meter. High
output combines with exceptionally flat phase
and frequency response over a wide operating
range of 60 Hz to 18 kHz. MICA's frequency
response, with its extended high-frequency
characteristics, is quite compatible with MILO
in applications where both loudspeaker types
are used.
The MICA low/low-mid section features two
high-power, neodymium magnet 10-inch
cone drivers with 2-inch voice coils, especially
designed for the power capability of the
system. Both drivers are housed in separate
vented enclosures within the loudspeaker,
located on the left and right sides. The two
high-power 10-inch drivers work in tandem
features & benefits
Very high power-to-size ratio
Exceptional fidelity and transient
response for intelligibility and high-
Seamless integration with MILO
at lower frequencies to take advantage of
their combined acoustic output, while one
family of
of the drivers rolls off before the crossover
frequency to maintain optimal polar and
frequency response.
The high-frequency section — at the center
between the two cone drivers — consists of
two neodymium magnet compression drivers
with 3-inch diaphragms and 1.2-inch exits.
These newly designed drivers are seamlessly
combined through a custom, patented Meyer
Sound REM™ ribbon emulation manifold,
coupled to a 100-degree horizontal constant-
directivity horn. This horn's controlled, very
narrow vertical dispersion is ideally suited
for use in curvilinear arrays, allowing minimal
destructive interaction in the high frequencies
between adjacent enclosures. Compared to
other methods, REM produces a smoothly
controlled wavefront with less distortion
and with the far higher output generated by
compression drivers.
All four MICA transducers are designed and
manufactured in-house, and are driven by
an integral, four-channel class AB/H ampli-
fier that provides 3020 watts of total out-
put power (6000 watts peak). The inte-
grated amplifier/processing circuitry includes
limiting to protect the drivers
and hold long-term power compression to
less than 1 dB. The field-replaceable elec-
tronics module incorporates Meyer Sound's
Intelligent AC™ power supply, which auto-
matically adjusts for any line voltage world-
Wide and even horizontal coverage
pattern across the full bandwidth
QuickFly rigging system with new
captive GuideALinks simplifies use in
flown or ground-stacked arrays
wide and provides both soft turn-on and
transient protection. The MICA loudspeaker
comes with the RMS™ remote monitoring
system interface installed. RMS offers com-
prehensive monitoring of system parameters
on a Windows
-based network.
MICA systems may be deployed in either
flown or ground-stacked configurations.
Newly designed QuickFly
rigging hardware
uses captive GuideALinks™ contained within
recessed guides in the front and rear corners
of the cabinet. A slot and convenient pinned
handle allow the link to be moved and pinned
for arraying or storage. The rear link permits
10 splay angles between 0 and 6 degrees (in
0.5-degree increments from 0 to 3 degrees,
and in 1-degree increments from 3 to 6
degrees); the two-position front link may be
set to add 7 degrees, adjusting coverage to
miss balcony fronts and other architectural
obstacles. The rigid connections allow easy
adjustment of array tilt, and often eliminate
the need for a pullback strap in flown configu-
rations. A single flown array can include up to
22 MICA loudspeakers with a 7:1 safety factor,
and 25 loudspeakers with a 5:1 safety factor.*
Options for MICA include a weather-protected
version with a rain hood to safeguard the
electronics, and custom color finishes. Top
and transition grids, a caster frame for
transporting stacks of multiple units, and
protective covers are available.
