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.
