CHAPTER 5
Using MICA with the 600-HP Subwoofer
A MICA array can be deployed in combination with Meyer
Sound 600-HP subwoofers in applications where the
extended low frequency output and other features of the
700-HP are not needed and the ones of the 600-HP are
desirable — compact size and versatile MICA-compatible
flying capabilities. The 600-HP subwoofer extends the
range of the system down to 36 Hz.
600-HP subwoofers with the optional MRF-600 can be
flown on the same array as MICA or they can also be
flown in an array next to MICA by using the MG-MICA
multipurpose top grid. In addition, 600-HP subwoofers can
be ground-stacked under a flown MICA array, next to a
MICA array, or in the same ground-stacked array.
Table 5.2 shows how you can integrate MICA with 600-HP
using the Galileo and LD-3 filtering capabilities to fine-tune
the system. All data in Table 5.2 is based on designs with a
2:1 ratio and in a close-proximity, coplanar orientation.
NOTE: When loudspeakers and subwoofers
are physically separated by more than 4
feet — or delay must be used between them — a
measurement system such as SIM should be used
to determine the correct delay and polarity.

NOTE: Depending on the desired SPL,
program content and system configuration,
applications using the 600-HP rather than the
700-HP might require a lower ratio to achieve
similar system headroom, e.g., three MICA and
two 600-HP.
