Meyer Sound M2D - Manual (Page 4)

M2D 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
on loading conditions and room
acoustics.
3. Free field, measured with 1/3 octave
frequency resolution at 4 meters.
4. Measured with music at 1 meter.
5. At this frequency, the mid- and
high-frequency transducers produce
equal sound pressure levels.
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 10-inch cone
drivers work in combination at low
frequencies (60 Hz – 350 Hz). At
mid frequencies (350 Hz – 575 Hz)
only one cone driver is fed from
the crossover to maintain optimal
polar and frequency response
characteristics.
8. The driver is coupled to a
constant-directivity horn through
a proprietary acoustical manifold
(REM).
9. Amplifier wattage rating based on
the maximum unclipped burst sine-
wave rms voltage that the amplifier
will produce into the nominal load
impedance. Low channel 30 V rms
(42 V pk) into 2 ohms; high channel
32 V rms (45 V pk) into 8 ohms.
10. No automatic turn-off voltages.
Voltages above 265 V AC are fuse
protected but may cause permanent
damage to the power supply.
Voltages below 90 V AC may result in
intermittent operation.
