POWER AMPLIFIER
– The
ACOUSTIC ARRAY
™ PRO
uses a state of the art, class D power amplifier design and a
high frequency auto-sensing universal switch-mode power supply (SMPS) to achieve unprecedented high performance
and lightweight packaging. For international use there are no voltage switches to change or jumpers to move. This
SMPS senses the line voltage from 100-240 Volts and automatically configures itself for the correct voltage. The
detachable mains IEC power cable with the proper plug configuration for the voltage source and country of operation is
required.
SPEAKER OUTPUTS
– The
ACOUSTIC ARRAY™ PRO
offers 2 paralleled
¼” speaker outputs. The combo speaker
load is 8 ohms and an additional 8 ohm cabinet may be added for a total load of 4 ohms, producing 300 watts of total
output.
POWER INLET CONNECTOR AND POWER SWITCH
–
The
ACOUSTIC ARRAY
™ PRO
utilizes a rear panel power
switch and power inlet connector. Use the correct mains IEC power cord required for the country where the amp is to be
used. The power supply auto-senses the correct voltage from 100V to 240 volts, 50 to 60 Hz for worldwide use.
NOTE
–
There is no externally accessible AC mains (line) fuse. The internal fuse is integral to the SMPS power supply
and is not user serviceable. This fuse will not fail except under very unlikely fault conditions to the SMPS. If this occurs a
qualified service technician is required to correct the problem.
SPEAKER SYSTEM DESIGN
–
The heart of the
ACOUSTIC
ARRAY™ PRO
design is the combination of
a 10” woofer in a
ported chamber and an integrated
4 x 2.5” neodymium cone-
driver line array placed directly in front of the woofer. This allows
all of the audio to project from a single point source for a more
even and seamless projection of all frequencies. The response
benefits of this design are unparalleled clarity, definition and
detail, ideal for the complexity of the chords and tonal variations
of acoustic instruments. Additionally, because the array column
reproduces the mid and high frequencies without a tweeter, the
top end clarity is even, articulate and smooth
– without excessive
hiss or harshness. Other major benefits of this design are
increased horizontal dispersion, more precise vertical pattern
control and deeper projection into the performance space.
CABINET DESIGN
–
The
ACOUSTIC ARRAY
™ PRO
offers a unique
cabinet shape that uses a 6-degree upward slant of the speaker baffle for
optimum projection and affords easy access to the control panel. This
cabinet shape is ideal for tight stages and provides superior audience
coverage. The cabinet is constructed of multi-layer poplar plywood
covered in an attractive dark brown/black vinyl and comes with nickel
corners and a soft molded strap handle. A metal speaker grille is used
with a center “pleat” to protect the line array speakers, and soft rubber feet
and a bottom mounted stand-adaptor round out the lower portion of the
cabinet.
