VA
4
Technology
The MQ Series uses the newly designed VA
4
10-in mid
frequency cone and phase plug assembly. Most cone drivers
smear arrival times in the upper mids because energy from
the dustcap leads that from the cone and surround.
Conventional circular-entrance phase plugs equalize the
smear but create directivity problems.
The VA
4
mid cone uses a more logical geometry that
equalizes arrivals at all frequencies. The phase plug, consist-
ing of expanding radial slots within a compressing frame,
lowers the mechanical reactance of the load facing the
transducer without modifying the directivity associated with
the source. This allows for faithful reproduction of upper
mid frequencies without any narrowing of beamwidth.
Arraying MH Series Enclosures
Unlike most mid/high and LF array module systems that
feature both 90° and 60° horizontal coverage, the MQ
Series lets users create tight packed clusters with 2x 90°
mid/high enclosures separated by an LF module. This is
extrememly effective for the center channel in large fan-
shaped venues using separate left-center-right arrays.
Conversely, arrays of 2x 60° enclosures separated by
an LF module require some degree of splay optimized to
the particular array's coverage requirements. Rigging
systems currently available allow users up to 10° of
overlap between mid/high modules.
Mounting/Suspension Facilities
Each MQ Series and associated woofer and subwoofer
system described herein contain (16) 3/8"-16 threaded
mounting/suspension points per cabinet, 4 each on the
top, bottom and sides. The exceptions are as follows:
MQ433: (24) 3/8"-16 mounting/suspension points per
cabinet, 6 each on the top, bottom and sides.
SB1000e: (4) 3-Position Flytracks (2 per side)
The integral mounting/suspension facilities can be used
with either commercially-available or custom fabricated
suspension systems. Any suspension systems should be
reviewed by a qualified structural engineer to ensure
adequate safety and compliance with local codes.
Processors
EAW MX Series processors are factory-configured to provide
the correct crossover, alignment, equalization and
protection for the loudspeaker systems served. The
following lists the processor units most commonly
used with MQ Series systems:
Processor Series
Processor Type
Description
MX300i
Analog
Stereo Three-Way
MX800i
Analog
Stereo Four-Way
MX8600
Digital
Stereo Two-Way/
Mono Three-Way/
Mono Four-Way
The MX8600 affords the most flexible approach to any sys-
tem. In addition to the loudspeaker-specific functions
required for proper system operation (crossover, driver
alignment, etc.), the MX8600 provides 5 bands of
parametric equalization which are fully accessible to the
user. These can be used for “house equalization” or other
functions. There is also a user-adjustable system delay which
can be used to synchronize loudspeaker clusters. Additional
information about the MX8600's features and capabilities
are included in the appendices to this application guide.
Special Versions
As with most EAW products, special versions of MQ Series
products are available. Some of the most frequently
requested variants are:
Finish:
Products can be factory painted to match any paint
color. Either the Pantone number of the desired color or a
paint chip is required.
Passive Crossovers:
MQ Series systems and TD412 low
frequency systems can be furnished with internal passive
crossovers.
Weatherproof:
Any MQ Series products can be ordered
in weatherproof versions.
