MILO 120 Specifications
1. The low-frequency power response of
the system will increase according to
the length of the array.
2. Recommended maximum operating
frequency range. Response depends
upon loading conditions and room
acoustics.
3. Measured with 1/3 octave frequency
resolution at 4 meters.
4. Measured with music at 1 meter.
5. At these frequencies, the transducers
produce equal sound pressure levels:
560 Hz for the low-mid and mid-high
and 4.2 kHz for the mid-high and
very-high frequency drivers.
6. Power handling is measured under
AES standard conditions: transducer
driven continuously for two hours with
band limited noise signal having a 6 dB
peak-average ratio.
7. To eliminate interference at short
wavelengths, the two 12-inch
drivers work in combination at low
frequencies (60 Hz – 180 Hz). At mid
frequencies (180 Hz – 560 Hz) only one
cone driver is fed from the crossover
to maintain optimal polar and
frequency response characteristics.
8. The three drivers are coupled to a
constant-directivity horn through
a proprietary acoustical combining
manifold (REM).
9. Amplifier wattage rating is based
on the maximum unclipped burst
sine-wave rms voltage the amplifier
will produce in to the nominal load
impedance low, mid and very high
channels 67 V rms (95 V pk) into 4, 6
and 8 ohms.
10. AC power cabling must be of sufficient
gauge so that under burst current RMS
conditions, cable transmission losses
do not drop voltage below specified
operating range at the speaker.
