MEYER SOUND MILO : High-Power Curvilinear Array
Loudspeaker
MILO. Compact Size, Surprising Power, Low Weight. It's Just Right......The
Meyer Sound MILO high-power curvilinear array is remarkably compact and lightweight
for a self-contained, four-way system — particularly considering that
it delivers 140 dB SPL peak output with exceptionally flat phase and frequency
response. MILO contains three dedicated very-high frequency transducers that
extend its operating range to 18 kHz, increase available high frequency headroom,
and result in extraordinary resolution of delicate transients, even in very
long throw applications.

ADVANCED M SERIES TECHNOLOGY
IN A VERSATILE PACKAGE
The Meyer Sound MILO is the same width as the M3D-Sub directional subwoofer,
though much smaller in other dimensions. This matched width affords seamless
configuration of combined MILO/M3D-Sub arrays for extension of low frequency
bandwidth and headroom. The combination also exhibits Meyer Sound’s
proprietary low-frequency directional control, so bass energy is effectively
steered away from areas behind the array.
Meyer Sound's MILO can serve as the keystone component in scalable, building
block systems comprising combinations of M Series products. For example,
MILO can be paired with the M3D line array for very large venue applications,
or transition to MICA compact high-power curvilinear array loudspeakers
for near field coverage where appropriate. The MILO 120 expanded coverage
high-power curvinlinear array loudspeaker provides the ideal complement
to MILO for downfill applications and shares the same dimensions and QuickFly
rigging components as MILO. All M Series products have compatible acoustical
and performance characteristics. |

Low/Low-Mid Frequencies: Power
and Definition
In the Meyer Sound MILO, the low/low-mid frequencies are reproduced by 12-inch
cone drivers. In the lowest frequency range, from 60 Hz to about 300 Hz,
both drivers are operating in tandem for maximum power, with each driven
by a dedicated amplifier channel providing 1125 watts of peak output. These
drivers are a new, proprietary design incorporating neodymium magnets for
higher efficiency and power handling with reduced weight. In common with
all other Meyer Sound MILO transducers, the 12-inch drivers are made in
a new, state-of-the-art manufacturing facility located at Meyer Sound’s
Berkeley headquarters. |
- Size and weight a perfect fit in M Series
- Same width as M3D/M3D-Sub for ease of transition
- Unique crossover promotes LF/MF definition
- Driver interference kept to bare minimum
|
In the critical low-mid band, Meyer Sound's MILO utilizes
a complex active crossover design to assure the smoothest possible response.
Above 300 Hz, where less power is required, the crossover feeds full signal
to only one of the two 12-inch drivers and rolls off the other. This ingenious
technique eliminates interference between the drivers that would otherwise
occur at shorter wavelengths, enabling MILO to maintain optimal polar
and frequency response characteristics throughout the low and low-mid
operating ranges.
Essentially, the Meyer Sound MILO divides the midrange frequencies into
two bands (low-mid and mid-high), with a dedicated driver (cone and compression,
respectively) assigned to each band. Because only one driver reproduces
each frequency band, Meyer Sound's MILO avoids the difficulties encountered
by other line array systems that attempt to reproduce the same midrange
frequencies using separate, multiple cone drivers — in some cases,
even cross-firing the drivers. Such techniques risk phase problems due
to multiple arrivals, and cross-firing can introduce undesirable combing
and lobing, even potentially modulating the high frequency signal. |
Mid-High to Very-High Frequencies: Greater
Output, Lower Distortion
In their designs for line arrays, most manufacturers recognize that the
high frequency vertical pattern of each loudspeaker must be tightly controlled
to minimize interference between units in the array. But some common solutions,
such as using long waveguides to collimate compression driver output,
gain the necessary control only at the cost of increased distortion.
By contrast, Meyer Sound's MILO employs two patented REM ribbon emulation
manifolds for the separate mid-high and very-high frequency sections,
each coupled to individual constant-directivity horns. REM is a proprietary
coupling device that introduces driver output to the horn throat across
a very short path (3 inches for the mid-high section and 1.5 inches for
the very-high section), effectively controlling the output but with dramatically
reduced distortion in comparison to other techniques. |
|
Meyer Sound's MILO mid-high section (560 Hz - 4.2 kHz) employs a single
1.5-inch exit, 4-inch diaphragm compression driver powered by a dedicated
560-watt amplifier channel. The very-high frequency section utilizes
three 0.75-inch exit, 2-inch diaphragm compression drivers to produce
extraordinary power and clarity, and also extend operating frequency
range up to 18 kHz. To provide maximum system headroom, power for the
very-high frequency section is supplied by a dedicated 1125-watt amplifier
channel.

|
Because high frequency drivers are
critical to overall system performance, all compression drivers in MILO
are designed and manufactured in house by Meyer Sound. Rigid manufacturing
tolerances and stringent quality control ensure stable, consistent response
characteristics. |
|
Two patented REM ribbon emulation manifolds couple
the four Meyer Sound compression drivers to the constant directivity horns.
REM controls driver output and introduces it to the horn throats within
the shortest possible path length, and consequently produces far less
distortion than devices in other line arrays that employ longer paths.

INTEGRATED AMPLIFIER AND PROCESSING
Meyer Sound's four-channel, class AB/H power amplifier and sophisticated
control circuits are all housed within the cabinet, dramatically simplifying
set-up or installation. To bring a MILO system online, you simply connect
AC power and line-level signal. That’s it! Touring companies can
quickly configure Meyer Sound's MILO arrays of various sizes to suit different
venues, and do so without having to either reconfigure amplifier racks
or haul in unneeded equipment because it’s already in the racks.
In fixed installations, there’s no need to pull long runs of heavy-gauge
loudspeaker cable, nor to wire and troubleshoot a room full of amplifiers
and loudspeaker processors. |
 |
- No amplifier racks
- No heavy gauge loudspeaker cables
- Simplified set-up or installation
- Enhanced reliability and flexibility
|
Meyer Sound's MILO on-board amplifier delivers a prodigious
3935 watts total burst power. TruPower limiting protects the drivers and
limits long-term power compression to less than 1 dB, versus 3 - 6 dB for
competing systems. The modular, field-replaceable amplifier/processing package
also incorporates Meyer Sound’s Intelligent AC power supply, which
automatically adjusts for any line voltage worldwide and provides both soft
turn-on and transient protection. An RMS remote monitoring system interface
is fitted as standard, allowing engineers to monitor and troubleshoot an
entire Meyer Sound MILO system from a remote Windows-based computer. |
