MICA Specifications
1. Recommended maximum operating
frequency range. Response depends
on loading conditions and room
acoustics.
2. Free field, measured with 1/3-octave
frequency resolution at 4 meters.
3. Measured with music referred to 1
meter.
4. At these frequencies, the transducers
produce equal sound pressure levels.
5. Power handling is measured under
AES standard conditions: both
transducers driven continuously for
two hours with band-limited noise
signal having a 6 dB peak-average
ratio.
6. Peak power handling is measured
with both transducers driven for 100
milliseconds with pink noise signal
having a 12 dB peak-average ratio.
7. The two drivers are coupled to a
100-degree horizontal constant-
directivity horn through a propri-
etary acoustical combining manifold
(REM).
8. Amplifier wattage rating based on
the maximum unclipped burst sine-
wave rms voltage that the amplifier
will produce for at least 0.5 seconds
into the nominal load impedance: 62
V rms low channels and 67 V rms high
channels.
9. Peak power based on the maximum
unclipped peak voltage that the
amplifier will produce for at least
100 milliseconds into the nominal
load impedance: 87 V pk low channels
and 95 V pk high channels.
10. AC power cabling must be of suf-
ficient gauge so that under burst
current rms conditions, cable trans-
mission losses do not drop voltage
below specified operating range at
the speaker.
