Introduction
The X1 and X2 loudspeaker system line-array elements by Electro-Voice represent an
important step in line-array technology for small- to large-scale fixed-installation and live
sound reinforcement. The various models are designed to significantly simplify the physical
assembly of a line array. Also, X1 in passive mode may be designed so that up to three
elements are powered from one (1) amplifier channel, the necessary crossover and EQ
functions accomplished with sophisticated internal passive networks. X2 is designed to
operate in Bi-amp mode only. The individual loudspeaker drivers, Hydra planar-wave
generators, acoustic waveguides, enclosures and rigging hardware were all designed
specifically for the X1 and X2 product line to not only achieve the highest acoustic output with
the highest fidelity, but also produce a precise wave front from each element to achieve state-
of-the-art line-array performance. The X12 subwoofer elements are designed to compliment
the performance of X1 and X2 full-range elements in applications where additional low-
frequency output is desired.
Although the X1 and X2 full-range elements are not physically symmetrical, their acoustic polar
responses are substantially symmetrical. Thus, stereo left and right arrays or left-center-right
arrays may be constructed with the elements in their normal right-side-up orientation.

drivers coupled to a MBH (Mid Band Hydra) and two (2) ND2R 2-inch-diaphragms (50.8 mm)
HF drivers. Each HF driver is mounted on a WCH (Wavefront-shaping Circular Hydra)
planar-wave generator and vertically orientated.
X1 is designed in a two-way configuration with a 90° horizontal x 10° vertical coverage pattern
and an internally selectable passive crossover/EQ network. The enclosure is trapezoidal in the
vertical plane with a 10° total included angle.
Each X2-212/90 full-range element consists of one (1) DVN3125 12-inch (304.8 mm) LF drivers
coupled to a MBH and two (2) ND6A 3-inch-diaphragms (76.2 mm) HF drivers. Each HF driver
is mounted on a PDH (Pin Diffraction Hydra) planar-wave generator and vertically orientated.
X2 is designed in a two-way configuration with a 90° horizontal x 10° vertical coverage pattern
for bi-amp use only. A passive crossover/EQ network is neither included nor available. The
enclosure is trapezoidal in the vertical plane with a 10° total included angle.
The X12-128 dual-18-inch subwoofer includes two (2) DVF4180 woofers designed specifically
for subwoofer applications, providing reliable low-frequency performance at high SPL levels
with low distortion and solid impact. Subwoofer elements do not have internal passive
crossovers and require an active crossover and dedicated amplifier channel(s) for proper
operation.
X12 is a compact rectangular dual-18-inch subwoofer element designed for use only as a
ground stack subwoofer array. The X12-128 is also designed to be used in ground stack
cardioid arrays.
All X1 & X2 elements are available in black and are supplied with the hardware necessary to
interface one element to another.
X12TC-GRID: standard grids for up to 24 X1 or X2 elements for simple or mostly straight
arrays, where extreme tilt angles are not required.
X12TE-GRID: extended grids for up to 24 X1 or X2 elements for extreme down angles in small
to medium arrays and typical up or down angles in large arrays.
X12PU-BGK: Pull Up Bottom Grid Kit for X1 or X2 elements. A pull-up kit is used when the
compression rigging method is being used with an array or when extreme down angles beyond
the capabilities of the extended grid are required.
The three (3) different grid options (X12TC, X12TE and X12PU-BGK) are sold separately.
Consult LAPS 3 for proper grid selection and array design.

Designing an X1 or X2 array
Applications for which X-Line Advance arrays are most
appropriate
The X1 and X2 loudspeaker systems are specifically designed to construct acoustically
coherent line-arrays. Line-array systems typically consist of independent columns of
loudspeaker enclosures. The most common implementation is a stereo sound reinforcement
system with two (2) columns (left and right). Additional columns are sometimes added to
cover different seating sections of a venue, e.g., seating areas that wrap around the side or
back of a stage. An additional column is also used in left-center-right configurations, with the
center channel for speech. In some venues, where stereo is not required, good coverage can
often be obtained with a single array. A variation of such a monaural system is the exploded
array, where two (2) or more widely spaced arrays are used to provide the horizontal coverage
required. Also, a large number of arrays may be used in distributed systems, such as in an
arena.
Notice!
The X1 and X2 line arrays, even though mechanically are identical, they are not designed
acoustically to work in the same column.
The exact number of X1 or X2 loudspeaker systems in a column varies depending on the
vertical acoustic coverage required for the specific venue. Furthermore, the relative vertical
angles between the boxes and SPL also depend on the venue’s acoustic coverage
requirements. Acoustic design techniques are outside the scope of this document and the
reader is directed to LAPS 3 (Line Array Prediction Software) or later modeling software
available from the Electro-Voice website www.electrovoice.com for acoustic design assistance.
Although the full-range X1 and X2 loudspeaker systems shown in Dimensions, page 9 are not
horizontally symmetrical, their acoustical polar responses are substantially symmetrical. Thus,
stereo left and right arrays, or left-center-right arrays may be constructed with the
loudspeakers in their normal right-side-up orientation.
Determining X1 and X2 array configuration with LAPS 3
LAPS 3 is software written in MATLAB with Excel-spreadsheet-based frontend interface for
determining optimum array configurations for a given venue and trim heights. The current
version of LAPS 3 is downloadable from the Electro-Voice website www.electrovoice.com.

Preparing X-Line Advance elements for installation
Recommended preflight procedures
For any installed sound system, certain checks made at the installer’s place of business can
prevent expensive on-site delays. A short-list follows, and sets the stage for proper array
performance:
1. Unpack all loudspeakers in the shop.
2. Check for proper model numbers.
3. Check the overall condition of the loudspeakers.
4. Check for continuity at the loudspeaker inputs.
It is a good idea, once on-site and the loudspeakers are connected, to check again for
continuity at the power-amplifier end.
Element configuration
After using LAPS 3 to design an appropriate array, it is recommended all necessary hardware
and accessories to suspend the array are checked and accounted for. Ensure all hardware is in
good working order, no defects, damage or imperfections are present, and all hardware is
capable of meeting or exceeding the total load requirements of the entire array.

Rigging system
Overview of the flying system
The IRS (Integrated Rigging System) on X1 and X2 was developed as a faster, safer way of
flying, aiming and landing a large vertical array.
Figure 6.1: Integrated Rigging System
Rigging the boxes together
The individual elements are fastened together by spring-loaded captive twist lock pins. The
captive twist lock pins are located at each of the four (4) upper corners and two (2) lower
front corners of each box. The upper pins attach each box to the extended link bars of the box
above it or grid. The pins are locked in their retracted (Open) position by grasping each pin
knob and pulling out as far as it will go, then turning the knob left or right to lock the pin in
the retracted position. The link bars of the box or grid above can then be dropped safely into
the V-blocks located at the top corners of the aluminum rigging. There is no fumbling for pin
holes because alignment is accomplished by the V-blocks. Once seated, the pins are engaged
by simply twisting each knob to unlock, allowing the spring to fire the pin into position. Lower
front link bars are released or retracted and locked into position the same way. Rear link bars
are set to the desired splay angle position with standard quick-release pins.

To rig the boxes together, do the following:
Notice!
Before flying the array verify the captive twist lock pins are fully engaged in the rigging (no
red showing between the pin knob and the box).
1. Pull and twist four (4) captive twist lock pins on the top of the lower enclosure.
Four (4) captive twist lock pins are locked in the retracted (open) position.
2. Extend the two (2) front link bars on the bottom of the upper enclosure.
3. Lock the two (2) captive twist lock pins for the two (2) front link bars.
4. Guide the link bars of the box or grid above into the V-blocks located at the top corners
of the aluminum rigging.
5. Twist the four (4) captive twist lock pins top of the lower enclosure.
Four (4) captive twist lock pins are unlocked in the engaged (Closed) position.

Setting rear link angles
The rear link angle is selected by choosing corresponding holes in the white ANGLE SELECT
sections of the rear rigging on each side (0°, 0.5°, 1°, 1.5°, 2°, 3°, 4°, 5°, 6°, 8°, 10°) as
determined by LAPS 3. Unless the rigging is locked into a rigid configuration by secondary pins
in the lower black ANGLE LOCK sections, the elements always default to 0° when lifted. Use
of the bottom pull-up grid accessory enables the array to be easily compressed with each
element stopping at its pre-selected splay angle. Smaller arrays may be rigidly pinned by lifting
the rear of each box until it hits the pre-selected angle stop, then inserting a second pin per
side into the appropriate hole in the ANGLE LOCK section. There is no fumbling for pin holes
because when lifted, the rigging will stop at the pre-selected position.
Figure 6.2: X1/X2 Rigging Hardware
Rear link angle selection
1. PIN PARK is used to park the unused pin.
2. RETRACT LOCK is used to lock the link bar in stored position.
3. ANGLE SELECT (in the white section) is used to set the desired splay angle from the
report from LAPS 3. This is used for both fixed-pin angles and rear-rigging compression
pull up.
▪0.5, 1°, 1.5, 2°, 3°, 4°, 5°, 6°, 8°, and 10° are the available angles for selection. For a 0º
angle, use the 0º angle hole in the Angle Lock section below.

▪DOLLY WHEEL (the 4º hole) is used to secure the bottom box of a stack to a dolly.
4. ANGLE LOCK (in the bottom black section) is used to lock the rear link bar for fixed-
pinned angles. Except for a 0º angle, this section is not used for rear-rigging compression
pull up.
▪0.5° and 1.5° are used to lock those two (2) angles.
▪ODD° is used to lock the odd number angles.
▪EVEN° is used to lock the even number angles and the 0º angle.
Single pin and double pin
Single pin compression method is used when a pull-up to the grid is employed to pull the rear
rigging together into compression. Double pin is used to set the rear rigging at fixed angles.
Ensure both sides of the loudspeaker are pinned identically.
To single pin or double pin, do the following:
1. Release the quick-release pin from RETRACT LOCK hole.
2. Lower rear link bar.
X-LINE ADVANCE Systems

3. Insert quick-release pin into desired ANGLE SELECT degree hole.
Verify pin is thoroughly pushed in and the blue button is released.
4. If using single pin repeat steps 1-4 on the other side of the loudspeaker.
Repeat this process on all elements in the array setting the angles per the report from LAPS
3.
OR
If using double pin continue to the next step.
5. Double pin: Push the rear link bar up until it contacts the stop pin in the angle select
hole.
6. Insert the second quick-release pin into desired ANGLE LOCK hole.

Electro-Voice Installation Manual 2015.04 | 02 | F.01U.310.953

Deciding which grid configuration to use
Choosing a grid is determined by the system down or up angles in combination with the
number of elements in the array and the splay angle between them. To determine which grid
model will achieve your desired angle or where the safety limitations are for the arrays, please
use LAPS 3 to design your array, and observe all warnings and limitation messages displayed
by the software.
X12TC-GRID compact grid
The X12TC-GRID compact grids are appropriate for arrays where extreme up or down angles
are not required. It is rated for a maximum hang of up to 24 X1 or X2 elements in a single
column. Use LAPS 3 to determine if X12TC-GRID combined with the number of elements will
achieve the acoustical coverage in the venue at a safe working load. For more information, see
Rigging structural strength ratings and safety factors , page 54
Notice!
X12TC-Grid comes with one (1) spreader bar only. The use of a second spreader bar is not
recommended with this grid.
X12TC-GRID includes one (1) spreader bar and two (2) sidearms. The spreader bar has four
(4) 0.84-inch (21.4 mm) holes through it for use as attachment points. The hole near the
center of the bar labeled PICK HERE is used for lifting a single point hang. This hole is slightly
off-center to compensate for the center of gravity of the respective X1 and X2 systems.
Pay close attention to which way the spreader bar is oriented with respect to the loudspeaker
systems. Compare the wording on the left end of the spreader bar to the input panel label on
the loudspeaker. For an X1 system, the bar should read X1 THIS SIDE TO REAR and for an X2
system it should read X2 THIS SIDE TO REAR.
!
Caution!
Verify the correct spreader bar orientation before lifting the array.
Failure to comply with this instruction results in the entire array tilting to one (1) side at an
unsafe angle.
Figure 6.3: X1/X2 spreader bar
The hole labeled SAFETY HERE is for attachment of a safety line if required by local
regulations. If used, ensure there is minimal slack in the safety line but it is not so tight as to
interfere with the vertical alignment of the array hanging from the pick point. The two (2)
