Meyer MILO High-Power Array Loudspeaker
The 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.

Audio Input
Type: Differential, electronically balanced
Max.common mode range: ±15 V DC, clamped to earth for voltage transient protection
Connectors: Female XLR input and male XLR loop output or VEAM
Input impedance: 10 kΩ differential between pins 2 and 3
Wiring: Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies
Pin 2: Signal +
Pin 3: Signal -
Case: Earth ground and chassis
DC Blocking: None on output, DC blocked through signal processing
CMRR: > 50 dB, typically 80 dB (50 Hz - 500 Hz)
Rf filter: Common mode 425 kHz, Differential mode 142 kHz
TIM filter: <80 kHz, integral to signal processing
Nominal input sensitivity: 0 dB V (1 V rms, 1.4 pk) continuous is typically the onset of TPL limiting for noise and music.
Input level: Audio source must be capable of producing a minimum of +20 dBV (10 V rms, 14 V pk) into 600Ω in order to produce maximum peak SPL over the operating bandwidth of the loudspeaker
