MILO 60 with the 700-HP Subwoofer
In applications where M3D-Sub features like directional
low-frequency control are not needed, a MILO 60 array
can be deployed in combination with Meyer Sound 700-
HP subwoofers. The 700-HP subwoofer extends the MILO
system frequency response down to 30 Hz.
Table 2 shows how you can integrate MILO (or combined
MILO 60/MILO/MILO 120) arrays with 700-HP using the
LD-3 line driver's filtering capabilities to fine-tune the
system. All data in Table 2 is based on system designs with
a 2:1 ratio and in a close-proximity, coplanar orientation.
When loudspeakers and subwoofers are physically
separated by more than 4 feet – or delay must be used
between them – a measurement system such as SIM
should be used to determine the correct delay and polarity.

LD-3 LINE DRIVER SETTINGS FOR THE MILO 60
LD-3 Array Correction
The LD-3 line driver's array correction filters are used to
compensate for the low and low-mid frequency buildup that
occurs in all line arrays. Because the low and mid-low sec-
tions of all MILO systems are identical, set the Array Type
to MILO and set the Array Size to match the total number
of loudspeakers in the array; this is true of reinforcement
systems consisting of the MILO 60 by itself or in combina-
tion with other MILO loudspeakers.
LD-3 Atmospheric Correction
Use the Atmospheric Correction section of the LD-3
to compensate for the air attenuation effects on higher
frequencies, which are especially noticeable in longer-throw
applications (typical of a stadium, an outdoor shed, and
other larger events). Enter the altitude plus the temperature
and humidity conditions at the venue, and then set the
distance from the array to the listeners to introduce the
correction. With the use of the individual distance settings
available on each of the outputs of the LD-3, the line array
can be divided into up to three sections to correspond to the
loudspeaker-to-audience distance for the near, medium and
long-throw sections of the array.

USING MAPP ONLINE™ FOR SYSTEM DESIGNS
INCLUDING THE MILO 60
The MAPP Online acoustical prediction program is a power-
ful, cross-platform, Java-based application for accurately
predicting the coverage pattern, frequency response,
impulse response and maximum SPL output of single or
arrayed Meyer Sound loudspeakers. Coverage data for the
MILO 60 cabinet is included in the MAPP Online database.
Detailed information on the use and application of MAPP
Online can be found in the MILO Operating Instructions at
the end of the "Line Arrays and System Integration" section.
MAPP Online can be accessed through the Meyer Sound
Web site at: www.meyersound.com.
WEATHER PROTECTION OPTIONS
A weather-protected version with a folding rain hood that
safeguards the electronics is optionally available. See Ap-
pendix A within the MILO Operating Instructions for details
on how to deploy the rain hood.
