Electro-Voice XLC Touring Addendum 3
0. Introduction
Purpose of this Addendum
This document is an addendum to the XLC Rigging Manual and describes several additional loudspeaker
system models and several rigging accessories for use with the XLC loudspeaker systems. In addition,
some updated information is presented for some items.
This addendum only provides additional information not found in the XLC Rigging Manual. Thus, the user
must consult the XLC Rigging Manual for all details concerning the structural ratings of the XLC loud-
speakers and for general rigging instructions to safely suspend an XLC loudspeaker system overhead.
Unless otherwise noted in the text in this addendum, all references to figures are for those contained in
this addendum. When figures are referenced from the XLC Rigging Manual, they are specifically refer-
enced as such.
New Loudspeaker Models
Several new loudspeaker models have been added to the XLC product line and are shown in Figures 1
and 2.
XLC127DVX: Three-way, LF/MB/HF loudspeaker system with a 120°H x 7.0°V coverage pattern. The
system includes one DVX3121 12-inch (305-mm) LF driver, two DN2065 6.5-inch (165-mm) MB driv-
ers and two ND6-16 3-inch (76-mm) HF drivers. An optional passive crossover may be purchased from
Electro-Voice that allows either biamp or triamp operation. The XLC127DVX utilizes the same 8° trapezoi-
dal enclosure as the XLC127, XLC127+ and XLC907DVX, and has the same standard XLC 8° rigging
frame secured to the left and right enclosure sides.
XLC907DVX: Three-way, LF/MB/HF loudspeaker system with a 90°H x 7.0°V coverage pattern. The
system includes one DVX3121 12-inch (305-mm) LF driver, two DN2065 6.5-inch (165-mm) MB driv-
ers and two ND6-16 3-inch (76-mm) HF drivers. An optional passive crossover may be purchased from
Electro-Voice that allows either biamp or triamp operation. The XLC127DVX utilizes the same 8° trapezoi-
dal enclosure as the XLC127, XLC127+ and XLC127DVX, and has the same standard XLC 8° rigging
frame secured to the left and right enclosure sides.
XLC215: Subwoofer loudspeaker system with two DVX3150 15-inch (380-mm) woofer. The XLC215
utilizes the same 12° trapezoidal enclosure as the XLC118 and has the standard XLC 12° rigging frame
secured to the left and right enclosure sides.
Several new XLC loudspeakers have been added to the product line since the original printing of the XLC
Rigging manual, as well as several new rigging accessories have been added. This addendum presents
those new items.

1. XLC Rigging System
1.1 XLC Enclosure Rigging Hardware Details
The XLC127DVX, XLC907DVX and XLC215 loudspeaker systems have been added to the product line.
These share the same enclosure shells and rigging as existing models. Consult the XLC Rigging Manual
for rigging hardware details, rigging attachment details and flying techniques.
All enclosure, rigging hardware dimensions and centers of gravity are shown in Figure 1 for the XLC127,
XLC127+, XLC127DVX and XLC907DVX loudspeaker systems, and in Figure 2 for the XLC118 and
XLC215 systems.
1.2 XLC Rigging Accessory Details
XLC A1 and B1 Grids
The XLC B1 grids are used for suspending a column of XLC full-range or subwoofer loudspeaker systems
overhead and is shown in Figure 3a. The grid consists of two sidearm assemblies and two spreader bar
assemblies. The front of the sidearm has a rectangular tube identical to that on the loudspeaker systems.
The hinge bar from the top loudspeaker system is inserted into the grid tube and pinned into place us-
ing the same quick-release pins from the loudspeaker. The rear of the sidearm has channel with a vertical
slot that is similar to that on the loudspeaker systems. The swing arm from the top loudspeaker system is
inserted into the grid tube and pinned into place using the same quick-release pins from the loudspeaker.
The grid sidearms are then attached to either one or two spreader bars. Two spreader bars are used when
two front-to-back pickup points are required. One spreader bar is used when two side-to-side pickup
points are required or one center pickup point is required.
Quick-release pins are used to secure the sidearms to the spreader bar. The width of the assembly
matches the width of all of the XLC full-range and subwoofer loudspeaker enclosure rigging.
The older A1 grid, shown in Figure 3b, was replaced by the newer B1 grid. The A1 grids only have one
middle hole in the spreader bar, while the B1 grid has three holes. The B1 grid is compatible with all XLC
loudspeaker systems, while the A1 is not compatible in some configurations with the XLC-DVX loud-
speaker systems.
XLC-EB Extender Beam
The XLC-EB, shown in Figure 3c, is an extender beam that may be used with the XLC grids to hang a
single column of XLC loudspeakers overhead. The extender beam enables greater tilt angles than can be
achieved by the grid alone. Two yoke assemblies on the XLC-EB are used to attach to the front and back
spreader bars of the XLC grid using quick-release pins. The extender beam may be oriented so it sticks
out behind the grid for a greater downward tilt or in front of the grid for a greater upward tilt.
When a single pick point is used, the tilt of the array is determined by the selection of the attachment po-
sition of a single pickup ring along a series of holes in the extender beam.
When two pickup points are used, one pickup ring is attached to the front of the extender beam and one
pickup ring is attached at the back. The tilt angle of the array is then adjusted by raising or lowering the
pickup points.
The XLC-EB extender beam is compatible with the older A1 grid and the newer B1 grid.

2. Rigging and Flying Techniques
2.1 Rigging the XLC Loudspeaker Systems and XLC Grids
Attach the top enclosure in the array to the grid, as shown in Figure 4a. (Only an XLC compatible grid can
be used with an XLC array.) The grid has front rigging tubes similar to the enclosures. Slide the front hinge
bar of the top enclosure into the front tube of the grid using the same technique that was used to link two
enclosures.
ALWAYS MAKE SURE THAT THE QUICK-RELEASE BUTTONS ON THE HINGE BARS FULLY
LOCK INTO THE ROUND HOLES IN THE FRONT RIGGING TUBES ON BOTH THE ENCLO-
SURE AND THE GRID.
The grid also has a rear rigging channel similar to the enclosures, except that the grid only has three at-
tachment holes available. Unlock the rear swing arm from the top enclosure by removing the quick-release
pin from the rear rigging channel on the enclosure. Pivot the rear swing arm on the enclosure up into the
rear rigging channel on the grid. Insert the quick-release pin from the grid through one of the three holes
in the rear rigging channel on the grid (top hole is 0°, middle hole is 2° up, and bottom hole is 4° up) and
through the hole in the swing arm. Repeat the process for the other side of the enclosure and grid.
ALWAYS MAKE SURE THAT THE LEFT AND RIGHT SWING ARMS ON THE ENCLOSURE
ARE LOCKED INTO THE SAME HOLES FOR THE SAME VERTICAL SPLAY ANGLE ON THE
GRID.
ALWAYS MAKE SURE THAT THE QUICK-RELEASE PINS FOR EVERY SWING ARM PASS
THROUGH THE HOLE IN THE SWING ARM AND ARE FULLY LOCKED IN THE RIGGING
CHANNELS IN THE GRID.
The grid sidearms are attached to either one or two spreader bars.
When two spreader bars are used, one is attached to the sidearms at the (one at the front and one at the
rear), the spreader bars are attached to the front and rear of the sidearms and two hoist motors are used
to lift the array. In this case, the hoist motors are used to adjust the vertical angle of the entire column of
loudspeakers. When one spreader bar is used, the vertical angle of the entire column of loudspeakers is
determined by the front-to-back position at which the spreader bar is attached to the sidearms. There are
a series of holes in the sidearms the user may select to adjust the vertical array angle.
Large quick-release pins that are tethered to the spreader bars are used to secure the side arms to the
spreader bars.
MAKE SURE THAT THE QUICK-RELEASE PINS ATTACHED TO THE GRID SIDEARMS FULLY LOCK
INTO THE HOLES IN THE ENDS OF THE SPREADER BARS. ALWAYS MAKE SURE THAT EACH
SPREADER BAR IS ATTACHED TO THE SAME HOLE ON THE LEFT AND RIGHT SIDEARMS.
The center of gravity of all current subwoofer systems (XLC118 and XLC215) and all older full-range
loudspeaker systems (XLC127 and XLC127+) is centered left to right. The older XLC A1 grids had one
hole in the center of the spreader bar when using a center pick point on the grid.

2. Rigging and Flying Techniques
However, the center of gravity of the newer DVX full-range versions (XLC127DVX and XLC907DVX) is
shifted off center towards the low-frequency side. The B1 grids were developed specifically to accommo-
date the different centers of gravity by having three holes in the spreader bars labeled A, B and C. Con-
figurations for rigging the various XLC loudspeaker systems are shown in Figure 4b.
When the left and right pick points on the spreader bars are used on the B1 grid, the center of gravity of
the enclosures is not a concern, and any of the XLC loudspeaker systems may be suspended as shown in
figure 4b.
The center of gravity of the enclosures is only a concern when using a single pick point on the spreader
bar(s). When lifting XLC127, XLC127+, XLC118 or XLC215 loudspeaker systems, use the middle hole
labeled “B” as shown in Figure 4c. When lifting XLC127DVX or XLC907DVX loudspeaker systems, use
the hole labeled “C” as shown in Figure 4d. When lifting XLC127DVX or XLC907DVX loudspeaker sys-
tems, use the hole labeled “A”. When XLC127DVX or XLC907DVX systems are mixed in the same col-
umn with XLC118 or XLC215 systems, use the hole labeled “C” as shown in Figure 4e.
The older A1 grids only had one hole that was equivalent to the hole labeled “B” on the B1 grid This
means that the A1 grids are not compatible with the XLC127DVX and XLC907DVX loudspeaker systems
in some configurations.
When the left and right pick points on the spreader bars are used on the A1 grid, the center of gravity of
the enclosures is not a concern, and any of the XLC loudspeaker systems may be suspended as shown in
figure 4f.
The center of gravity of the enclosures is only a concern when using a single pick point on the spreader
bar(s). The A1 grid may be used for lifting XLC127, XLC127+, XLC118 or XLC215 loudspeaker systems,
as shown in Figure 4g. However, the A1 grid is not compatible with the XLC127DVXand XLC907DVX
loudspeaker systems when using a single pick point on the spreader bar(s)
The A1 grids may be modified to become B1 grids. Consult the Electro-Voice service department for
details.
