SRM450v2
The Mackie SRM450v2 is a full-range, portable, powered
loudspeaker system providing high-output, ultra-wide
dispersion and low-distortion performance in a compact,
lightweight design. Two Fast Recovery™ amplifiers
independently power a 12-inch neodymium woofer and a
precision titanium compression driver. Mackie’s
sophisticated Active electronics provide phase correction,
crossover, time correction, equalization and protection
circuitry.
A heat-treated titanium compression driver with multi-cell
aperture directs pristine highs through an exponential high-
frequency waveguide, allowing for ultra-wide dispersion.
This allows the SRM450v2 to deliver clear, smooth sound to
audience members up to 45° off axis.
The 12-inch neodymium woofer provides a greater magnetic
field with far less material, making the woofer extremely
lightweight without sacrificing performance. The 3-inch voice
coil allows the driver to run cooler, delivering consistent
performance even after long hours of use.
Mackie-designed Active electronics provide equalization,
crossover, time alignment, and phase correction to enhance
sonic performance. Protective circuitry includes
over-excursion protection, low-line voltage shut-down,
thermal protection, level dependent low-frequency roll-off and
independent LF and HF limiters.
The SRM450v2 features a number of dedicated controls
includ
ing a mic/line switch, a single microphone and line input
level control,
and a contour switch for low-level sound
reinforcement applications. There is also a timed turnoff feature
that turns off the amplifiers if the signal drops below –45 dBu
for three minutes.
The center of gravity, handle locations, handle design, position
of fly-points and ease of use have been ergonomically designed.
There is also an integrated pole mount cup and a weather-
resis
tant steel grille. The asymmetrical trapezoidal cabinet has
been designed to provide an ideal floor monitoring position.
The cabinet is constructed of high-pressure injected
polypropylene. The enclosure features ample amounts of
reinforcement ribbing and structural strengthening resulting
in a strong, super-rigid design providing ideal acoustical
characteristics.
APPLICATIONS
Small to mid-size club/band PA systems, houses of worship,
DJs, vocal/band monitor wedges, gymnasiums, banquet
halls, conference rooms and many, many more.
