CHAPTER 5
The block diagram below (Figure 5.3) shows one method of
driving this example array, along with subwoofers (not in the
MAPP Online Pro predictions).
CAUTION:
This example is not meant to
be used as a template for your own system
designs. Acoustical characteristics, physical
constraints, audio content, audience, and other
relevant factors should always be uniquely weighed
into your own applications on a project basis.
USING M’ELODIE AS SIDEFILL OR DOWNFILL
WITH MICA CURVILINEAR ARRAYS
The M’elodie loudspeaker’s acoustical characteristics
promote seamless integration with MICA when used as
downfill in MICA curvilinear arrays (via the MTF-MICA/
M’elodie transition frame), as well as when M’elodie arrays
are being used as sidefills along with MICA main arrays.
Understanding the differences and similarities between the
two loudspeakers is very important for designing and for
fine-tuning system coverage.
For a combined MICA/M’elodie array, the design will be
dependent on three factors:
■
Number and Type of Array Elements. Determining the
number of elements of each type to use is critical. The
number of elements drastically affects the uniformity
of coverage of both SPL and frequency response. The
number of longer-throw, higher SPL elements (MICA)
and downfill (M’elodie) needs to be carefully selected.
■
Vertical Splay Angles. Changing the splay angles
between cabinets has a significant impact on vertical
coverage, with the result that narrower vertical splay
angles produce a higher Q vertical beamwidth and
longer throw in the top elements (MICA), while wider
splay lowers the Q at high frequencies for coverage on
the lower elements (M’elodie).
■
Horizontal Coverage. The horizontal coverage of the
MICA and M’elodie sections can be considered fairly
constant, regardless of the number of array elements on
each section or the angles between them.
