The Meyer Sound UPA-2P is distinguished by the extraordinarily
smooth and predictable behavior of its proprietary high-frequency horn.
The result of intensive research in Meyer Sound’s anechoic chamber,
the patented UPA-2P horn design exhibits constant Q. The beamwidth remains
consistent within close tolerances, in both the horizontal and vertical
planes and across the horn’s operating frequency range of 1000 Hz
to 18 kHz. The result is uniform attenuation of all frequencies outside
the specified beamwidth with minimal side lobing. Uniformly predictable
polar behavior takes much of the guesswork out of system design and assures
arrays that exhibit minimal destructive interference.
Each driver of the Meyer Sound UPA-2P is individually powered by a dedicated
channel of the proprietary class AB/bridged amplifier with complementary
MOSFET output stages. Total power is 550 watts. The incoming audio signal
is processed through an electronic crossover and correction filters for
flat phase and frequency response as well as for driver protection. Phase-corrected
electronics ensure flat acoustical amplitude and phase response, resulting
in exceptional impulse response and precise imaging.
The field-replaceable amplifier/processing package in the Meyer Sound
UPA-2P incorporates Intelligent AC™, which auto-selects the correct
operating voltage, suppresses high voltage transients, filters EMI and
provides soft-start powerup. The high common-mode rejection of the laser-trimmed
differential input circuit permits long signal runs through a simple shielded
twisted-pair cable. Audio input modules accommodate a range of applications.
The standard version offers looping XLR input and output connectors, while
an enhanced looping version adds polarity switching (the looping output
is not affected) and input attenuation (0 dB to -18 dB). A summing mono
version with two inputs is also available.
The durable trapezoidal enclosure of the Meyer Sound UPA-2P is covered
with a black textured hard-shell finish. A protective hex-stamped steel
grille and charcoal grey foam cover are included. Standard rigging points
are four ring and stud pan fittings (two each, top and bottom) with load
rating of 420 lbs (190.51 kg) at a 5:1 safety factor. The optional 30-degree
rigging frame, adjustable yokes and pole mount adaptors allow fast, flexible
installation and easy aiming. Options include weather protection, custom
color finishes, and cabinets with no handles for fixed applications requiring
specific cosmetics.
The UPA-2P is compatible with the RMS™ remote monitoring system,
which offers comprehensive monitoring of system parameters on a Windows®-based
network. |
