Teknik DN8000 2-in/5-out controller is rec-
ommended. Linkwitz-Riley crossover filters
with a minimum slope of 24 dB per octave
at 125 Hz and 1,760 Hz are recommended.
Both the Dx38 and the DN8000 offer ap-
propriate filtering, equalization and signal
delay capabilities to provide optimum per-
formance of the X-Array
™
loudspeaker
systems. Digital parameter settings for
both controllers are avaialble upon request.
Electrical Connection and System
Wiring
Two paralleled Neutrik 8-pin Speakon
®
con-
nectors are used for electrical connection to
the Xf loudspeakers with the following pin
assignments:
HF:
Pins 4 Paralleled
MB:
Pins 3 Paralleled
The Xf wiring diagram is shown in
Figure 7. Since the connectors are paralleled,
it does not matter which connector is used
as the input or output when paralleling Xf
systems. Although Pins 1 and 2 are not used
by the Xf systems, they are paralleled on the
input panel. This allows an X-Array
™
bass
box (like the Xb – which uses Pins 1 and 2,
but not Pins 3 and 4) to be paralleled with
an Xf, allowing all eight conductors to be
used with a single cable run to the amplifi-
ers. Note that, when two Xf systems are
jumped from one to another via the input/
output connections, the amplifier home-
run cable will have four high-frequency
drivers on Pins 4 (for a 4-ohm load) and
four mid-bass drivers on Pins 3 (for a 4-
ohm load).
Flying the X-Array
™
Systems
The X-Array
™
loudspeaker systems all uti-
lize the same rigging hardware and have the
same structural strength ratings. Thus, dif-
ferent systems may be mixed in an array to
achieve the best acoustic results. The rigging
system allows for the smallest possible spac-
ing between adjacent enclosures, and uti-
lizes quick-release rigging fittings for fast
installation and tear down.
When flown, the X-Array
™
enclosures are
linked together by two removable hinges on
the rear of the enclosures at the top and
bottom. This arrangement enables the en-
closures to pivot vertically from the rear
corners. The relative vertical angle between
adjacent enclosures is adjustable and set
by two removable rigging straps on the
front of the enclosures at the top and bot-
tom. Both the rear rigging hinges and the
front rigging straps are installed when en-
closures are sitting on top of one another.
For ease of installation of the hinges and
straps, the enclosures self align using feet
and cups mounted on the top and bottom
of the enclosures. The relative horizontal
angle between adjacent columns of loud-
speakers is set by adjustable grids at the
top of the array (or by custom-building at-
tachment supports in permanent-installa-
tion applications where grids are not used).
The removable proprietary rear rigging
hinges utilize all-steel construction and are
secured into a proprietary track assembly on
the enclosure (similar to the heavy-duty air-
craft L-track). The aluminum track is ex-
truded as a single-piece track/angle-bracket
assembly and ties into the top, bottom and
rear of the enclosure. Metal bars inside the
enclosure tie the top and bottom track/
angle-bracket assemblies together, minimiz-
ing the load applied to the wooden enclo-
sure. The rear extrusion will accommodate
the New Haven 32102-2 aircraft-type
double-stud locking fitting instead of the
hinge for applications requiring a lower-
strength rating.
The removable, front strap assemblies uti-
lize all-steel New Haven 32102-2 aircraft-
type double-stud locking fittings and wire
rope and are secured into another propri-
etary track similar to the heavy-duty air-
craft L-track. The track is extruded as a
single-piece track/angle-bracket assembly
that ties into the front and side of the enclo-
sure. The track/angle-bracket assembly ex-
tends from the top to the bottom of the en-
closure, eliminating the load applied to the
wooden enclosure.
A complete line of flying-hardware acces-
sories is available for the X-Array
™
loud-
speaker systems, including a grid, rigging
hinges and rigging straps. The variety of rig-
ging hinges and front rigging straps avail-
able include those for linking two enclosures
together, securing the top enclosure in a col-
umn to a grid and for picking up the top en-
closure in a column without a grid. Consult
the X-Array
™
Accessories section for a com-
plete listing of the available rigging acces-
sories.
The total weight of a column of X-Array
™
loudspeaker systems that may be supported
by the X-Array
™
rigging system varies from
454-726 kg (1,000-1,600 lb) depending on
the rigging configuration details. An
X-Array
™
Flying Manual is available from
Electro-Voice and is included with each
X-Array
™
system shipment. The manual
should be consulted for complete structural
specifications and detailed instructions for
safely suspending and using the X-Array
™
systems.
Field Replacement
Normal service for the Xf requires only a #2
Phillips screwdriver and a 3/16-inch hex-key
wrench. The drivers may be accessed as fol-
lows:
HF: First remove the grille, then remove the
screws securing the front flange of the high-
frequency horn. Lift the horn and driver out
of the shroud assembly. In the event of fail-
ure, the diaphragm assembly can be replaced
with the driver attached to the horn.
MB: Remove the screws securing the hatch
on the back of the enclosure, and lift the
hatch out. Remove the screws securing the
12-inch driver and lift the driver out of the
enclosure. In the event of failure, the en-
tire driver must be replaced or reconed.
The following service parts are available
from the service department in Buchanan,
MI USA:
HF: #84233-XX 16-ohm ND5-16
diaphragm kit
#827-2973 ND5-16 complete driver
MB: #812-2858 ND12A complete driver.
The complete drivers are available only for
repair replacement and are not available
for general sale.
