Meyer Sound M'elodie, Operating Instructions Manual

CHAPTER 1

The self-powered M’elodie ultracompact high-power 
curvilinear array loudspeaker is a member of the popular 
MILO

®

 family of loudspeakers. Its extended high-frequency 

headroom gives it a smooth sound over its wide operating 
frequency range of 70 Hz to 18 kHz. This headroom 
combines with a 100-degree horizontal coverage pattern to 
provide detailed resolution of delicate transient information 
across a broad coverage area.

array loudspeaker

M’elodie is ideal for creating high-power arrays with a 
very small footprint for applications that do not require the 
power and throw distance of the MICA™ compact high-
power curvilinear array loudspeaker, or where reduced 
size and weight are advantageous. With its easy-to-use 
and versatile QuickFly rigging, M’elodie is equally suited 
to touring, rental, and fixed installation applications. High 
power-to-size ratio, low profile, and ease of use makes it 
an outstanding performer in corporate AV applications, and 
ideal for smaller venues such as theatres, ballrooms, and 
clubs. In spite of its small size, M’elodie produces a peak 
output of 131 dB SPL with exceptionally flat phase and 
frequency response, making it capable of filling much larger 
spaces than one might expect.

M’elodie is designed to integrate smoothly and easily with 
other Meyer Sound products. For example, while M’elodie 
can be used as a main system, individual M’elodie cabinets 
work well for under-balcony coverage and frontfill. Since 
its sound and rigging are designed to pair seamlessly 
with MICA, M’elodie is an excellent downfill or sidefill 
complement to a MICA main system for tours playing a 
variety of venues. Available QuickFly rigging, which features 
captive GuideALinks™ for  maximum flexibility and safety, 
makes it easy to create standalone arrays as well as add 
M’elodie as downfill to a MICA array. In fact, M’elodie can be 
a key component of a total Meyer Sound system solution.

M’elodie is available in custom color finishes, allowing it 
to blend in with any environment. A weather-protected 
version with wood-treated enclosure and rain hood is also 
available to safeguard the user panel and connectors from 
the elements.

ADVANCED M’ELODIE TECHNOLOGY

The M’elodie loudspeaker is a self-powered, three-way 
design featuring drivers designed and manufactured at 
Meyer Sound’s Berkeley, California, factory. 

The low/low-mid section features two high-power, 
neodymium-magnet, 8-inch cone drivers with 1.5-inch 
voice coils, created to meet the power requirements of the 
system. The drivers are a proprietary design employing 
neodymium magnets for higher efficiency and power 
handling with reduced weight. The lowest frequency range 
is reproduced by these high-power drivers working in 
tandem, each powered by a dedicated amplifier channel. 

To assure the smoothest response in the critical midrange 
and crossover region, M’elodie incorporates a complex 
active crossover design. For low frequencies, both drivers 
work together, but in the low-mid frequencies only one of 
the two 8-inch drivers is active. This technique eliminates 
interference between the drivers that would otherwise occur 
at shorter wavelengths, while at the same time maintaining 
optimal polar and frequency response characteristics at the 
crossover frequency. 

The high-frequency section uses a 1.2-inch exit, 3-inch 
diaphragm compression driver with a neodymium magnet, 
powered by a dedicated amplifier channel. The output of 
the driver is coupled to a 100-degree (horizontal coverage) 
constant-directivity horn through a custom REM™ manifold. 
The REM is a patented coupling device that introduces 
driver output to the horn throat across a very short path, 
effectively controlling the dispersion characteristics, but 
with dramatically reduced distortion in comparison to other 
techniques. 

INTEGRATED AMPLIFIER AND PROCESSING

As a self-powered loudspeaker, M’elodie incorporates 
a high-power, 3-channel, class AB/H power amplifier 
and sophisticated control circuitry housed within the 
cabinet, dramatically simplifying setup and installation. 
Supply power distribution to the array, connect a line level 
signal, and it’s ready — leaving you to focus on design 
implementation instead of installation. 

The M’elodie loudspeaker’s on-board amplifier delivers 
1275 watts total burst power (2550 watts peak). Dedicated 
limiters protect and extend the life of the drivers at very high 
levels and prevent severe non-linear circumstances.
