Meyer Sound MILO

OteSound company made an investment into state-of-the-art Meyer Sound MILO system. MILO is a line array system designed for demanding medium-to-large scale venues that requires high power and musical fidelity.


Each MILO cabinet comprises four power amplifier, electronic crossover and the other signal processing circuitry. All that stuff is housed within the cabinet. All you have to do is connect signal and power lines.


The MILO loudspeaker is designed as a four-way system.


The lowest frequency range (60Hz – 300Hz) is reproduced by dual 12” cone drivers working in tandem, each powered by a dedicated amplifier channel with 1125W of RMS output. To assure the smoothest response in the critical midrange (300Hz – 560Hz) MILO incorporates a complex active crossover design. In the low-mid band the crossover feeds only one of the two 12” drivers while rolling off the other driver. 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 frequencies.


MILO’s mid-high section (560Hz – 4.2kHz) uses a single 1.5″ exit, 4″ diaphragm compression driver powered by a dedicated 560W of RMS output.


The very high-frequency (4.2kHz – 18kHz) section utilizes three, 0.75″ exit, 2″ diaphragm compression drivers. Power for the very high-frequency section is supplied by a dedicated amplifier, which is capable of producing 1125W RMS, with enough headroom to reproduce all the dynamics of the upper frequency range.


All in all MILO’s on-board amplifier delivers 3935W RMS power.


MILO employs two 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 transmits driver output to the horn throat across a very short path while matching the same phase response. This technique dramatically reduced distortion in comparison to other ones.


Let’s mention limiter system design. The limiting system is called TruPower Limiting (TPL). A conventional limiter assume constant loudspeaker impedance so it sets the limiting threshold by measuring voltage only. This is quite inaccurate method because the loudspeaker’s impedance varies throughout its frequency range. Moreover the impedance also changes with temperature variations in the voice coil. Consequently, conventional limiters begin limiting prematurely, which under-utilizes system headroom and shrinks the loudspeaker’s dynamic range. In contrast, TruPower Limiting (TPL) accounts for varying loudspeaker impedance by measuring current as well as voltage to compute the actual power dissipation in the voice coil. TPL improves performance before and during limiting by allowing each driver to produce maximum SPL across its entire frequency range. In addition, TPL eliminates power compression when the system is operated at high levels for extended periods, and also extends the driver life cycle by controlling voice coil temperatures. The limiting circuitry utilizes optical limiters that add no noise and have no effect on the signal.


MILO is fitted standard with Meyer Sound’s RMS™ (Remote Monitoring System) interface, giving the capability to monitor and troubleshoot an entire RMS-equipped Meyer Sound system from PC.
