High Definition
Reinforcement
Loudspeakers
The Meyer Sound
UPL-1 and UPL-2 are
self-contained, high-
definition, powered
loudspeakers suitable
for a wide variety of
high quality sound
reinforcement appli-
cations. The UPL-1
and UPL-2 incorpo-
rate line-level control
electronics mounted
within a rear panel
chassis, including:
•
dual power
amplifiers for
biamplification
•
an active balanced
input circuit with
switchable sensi-
tivity (+4 dBu or
-10 dBV)
•
an active crossover
utilizing optimized
pole-zero filter
combinations to
achieve acoustical
transparency and
linear phase
•
independent pro-
tection circuits for
each loudspeaker
driver
The UPL-1 and UPL-2 are two-way systems
comprising a 10-inch cone low-frequency
driver and 1-inch high-frequency driver housed
in a vented cabinet. Both drivers are of a pro-
prietary design, and are individually selected
for maximum linearity. The high-frequency
horn driver employs a titanium dome and silk
suspension in a patented, low distortion design
(US patent number 4,152,552). It is coupled to
a 90
°
by 40
°
modified radial horn in the UPL-1,
and to a 60
°
aspherical waveguide in the UPL-2.
Aligned to closely approximate true point
source radiators within their coverage area,
the UPL-1 and UPL-2 feature tightly controlled
time delay response with minimal deviation
from linear phase across the full frequency
range of their operation. Each unit is individu-
ally factory-calibrated to ensure a free-field
frequency response that is flat within
±
2 dB
from 50 Hz to 18 kHz. The UPL-1 and UPL-2
each deliver 124 dB peak SPL (1 meter) with
>100 dB dynamic range.
