| The system features two specially designed high-power
15-inch cone drivers, engineered to provide optimal performance in subwoofer
applications. The high-excursion, back-vented drivers have 4-inch voice
coils, and each is rated to handle 1200 watts (AES)*. The two cone drivers
are housed in a rectangular, optimally tuned and vented enclosure that
is the same width as MICA, and a few inches higher and deeper. The enclosure
geometry makes vertical ground-stacking easy and convenient. All versions
include plastic skids on the bottom of the unit to prevent damage to the
enclosure or the unit below; the skids align with slots on the cabinet’s
top to ensure secure stacking.Operating frequency range is from 36 Hz
to 150 Hz, with a peak SPL at one meter of 138 dB.
Each cone driver is driven by a channel of the integral two-channel class
AB/H amplifier with complementary MOSFET output stages. Total output power
is 2250 watts (4500 watts peak), providing the system with sufficient
headroom to accommodate the most extreme sound reinforcement demands with
ease. The circuitry includes TruPower® limiting to extend the life
of the drivers and hold long-term power compression to less than 1 dB.
The amplifier, control electronics, and power supply are integrated into
a single, field-replaceable module that is mounted into the rear of the
enclosure.
The optional MRF-600 rigging frame uses captive, rigid GuideALinks contained
within recessed guides in the lower front and rear corners of the enclosure.
A slot and convenient pinned handle allow the link to be moved and pinned
for arraying or storage. The versatility of angles achieved by using combinations
of front and back positions allows a MICA array suspended under 600-HP
subwoofers to be
uptilted for balcony coverage up to 15 degrees, or downtilted to 6 degrees
with respect to the 600-HP. The 600-HP can make use of the optional MG-MICA
rigging grid to accommodate a variety of flown and stacked configurations.
The durable enclosure is constructed of premium birch plywood coated
with a black, textured hard-shell finish, with a powder-coated, hex-stamped
steel grille lined with acoustical black mesh to protect the drivers.
The exterior dimensions of the 600-HP are suitable for both European and
U.S. trucks, and it can securely travel in stacks using the MCF-MICA caster
frame, or MDB-600 dolly board when not fitted with rigging frames.
Options for the 600-HP include weather protection and custom color finishes
for fixed installations and other applications requiring specific cosmetics.
The RMS™ remote monitoring system — standard with the rigging
version and optional with other configurations — allows comprehensive
monitoring of system parameters on a Windows®-based network.
