PRODUCT DESCRIPTION
Biamp's Community L SERIES LVH-900 Beamforming Venue
Horn, combined with the Community Amplified Loudspeaker
Controllers (ALCs), precisely tailor the directivity of each
loudspeaker, or array of loudspeakers, to meet the sound
requirements in any application.
Designed for exceptional performance in large venues,
each LVH-900 model consists of four 12-inch LF drivers,
three Community M200E midrange compression drivers
and four 1.5-inch HF compression drivers. Using patentpending techniques, all drivers integrate into a single triaxial
waveguide that fills the entire 36 x 31-inch face of the
enclosure, providing pattern control to below 400 Hz. The
LVH-900 models offer 60 or 90 degrees of fixed horizontal
dispersion.
The LVH-900 Active Standard (AS) models allow DSP
settings and control of individual driver pairs to provide
uniform sound to the audience areas. The LVH-900/AS
models have presets for vertical dispersion beamforming in
60°, 40°, 20° configurations.
The LVH-900 Active-Plus (AP) models use advanced
FIR techniques to seamlessly combine the output of two
loudspeakers into one coherent wavefront, providing higher
output or wider coverage patterns. LVH-900/AP models
have presets for vertical dispersion beamforming in 100°,
80°, 20° configurations.
Typical applications include music and speech reinforcement
for large houses of worship, stadiums, theaters, and much
more. Possessing advanced features, highly-focused
dispersion patterns, weather-resistant construction, and
most importantly sonic excellence, LVH-900 loudspeakers
make installations not only fast and simple, but as functionally
effective as possible.

RIGGING AND ELECTRICAL SAFETY
IMPORTANT: The loudspeakers described in this manual are
designed and intended to be mounted to diering building
surfaces using a variety of rigging hardware, means and
methods. Installation of loudspeakers should only be performed
by trained and qualied personnel. All electrical connections
must conform to applicable city, county, state, and national
electrical codes or standards.
. DANGER: It is possible to experience severe electrical shock
from a power amplier. Always make sure that all power
ampliers are in the "OFF" position and unplugged from an AC
Mains supply before performing electrical work.
IMPORTANT: Refer to the sections on installation and
connections later in this manual for additional information on
rigging and electrical safety.
IMPORTANT: Any open threaded inserts in the sides of each
enclosure must have threaded fasteners inserted to seal the
enclosure from air leaks. If the threaded ttings do not remain
sealed, air leaks will occur in the enclosure that may
compromise the low-frequency performance with distortion,
reduced output, and premature driver failure.

INSTALLATION
Installation preparation
The LVH-900 is securely packed one to a carton on a pallet.
1. Move the pallets to the assembly area.
2. Remove strapping and wrap to expose the carton.
3. Remove the carton top and cardboard sleeve. The
speaker is positioned face (grille) down in the bottom
tray.
4. Review the safety information enclosed and reserve the
hardware packet for later use.
5. See page 4 for mounting / suspension points.
The LVH-900 models explained:
There are functional differences between the /AS (Active
Standard) and /AP (Active Plus) models described below. It is
important to order the appropriate models for your application.
Your system designer should have modeled the system using
EASE® Focus3 (EF3) software (available free from AFMG®
here)*. The latest LVH-900 GLL (loudspeaker file) is available
on the Biamp website (here) The report generated will
dictate the models, splay plate types and quantities needed.
The WR (weather-resistant) models are designed to comply
with, and pass IEC 60068-2-5 Solar Radiation, IEC 60068-2-11
Salt Mist, IEC 600682-42 SO2, IEC 60068-2-60 Chlorine, and
IEC 60529 IP56 test conditions
LVH-900/AS (Active Standard) models
• Are always used as single cabinet point sources.
• Internally the HF & MF drivers are wired in pairs –
outside pairs and inside pairs – each driver pair is driven
by different FIR settings, manipulating the phase to
create the single cabinet beamformed patterns.
Note: Since there are only 3 MF drivers they are
wired to the input panel as MF1&3, and MF2.
• Recommend a total of 6 amplifier channels to drive each
cabinet.
*EASE® and AFMG® are registered trademarks of
AFMG Technologies GmbH.
LVH-900/AP (Active Plus) models
• Must be ordered as two (2) /AP cabinets in order to
create one dual array.
• Are always deployed in pairs. Two ‘/AP’ cabinets are
arrayed together to create one single, larger LVH
loudspeaker. The proper mechanical splay between
cabinets must be paired with matching FIR settings.
• Provide additional output and/or wider coverage patterns
than are available from single ‘/AS’ models.
• The input panels provide wiring access to each HF & MF
driver individually. Mirrored FIR settings are sent to the
upper and lower cabinets in the pairs, allowing the two
cabinets to act as one large loudspeaker.
• Like the ‘/AS’ version, the HF & MF drivers are driven as
pairs but in the ‘/AP’ version the drivers in each pair are
located in two different cabinets. There are four (4) HF
pairs and three (3) MF pairs of drivers driven across the
dual ‘/AP’ loudspeaker array.
• '/AP' arrays recommend a total of 11 amplifier channels
for each array.
• Use of a single '/AP' speaker is not currently supported.

Mounting Points
There are at least four mounting points on each side, top and bottom that may be
used for rated eyebolts, splay brackets, or rigging frames. The existing (M10) flat
head bolts may be removed and replaced with M10 mounting hardware (thread
length between 35-45mm). Please note that the center larger holes in the side panel
take M12 size hardware and represent the center of gravity (CoG) of the cabinets.
IMPORTANT - Rigging point WLL:
M10 rigging point is 200 lbs (10:1 Safety rating) - recommend 4 suspension points;
M12 rigging point is 250 lbs (10:1 Safety rating) - recommend 2 suspension points

WARNING: Do not use any hardware connection points
other than the M10s or M12s as indicated for lifting,
suspension, mounting, or secondary safety points.
IMPORTANT: Any open threaded inserts in the sides of
each enclosure must have threaded fasteners inserted
to maintain structural integrity and seal the enclosure
from air leaks which may compromise LF performance.
Additionally, weather-resistant (WR) models must have
hardware fully threaded in all of the holes to prevent
moisture from entering and interfering with
performance.
CAUTION: Do not disconnect or utilize any hardware in
the plastic cups, grille or input panels unless specically
instructed. They are not rigging points and are
necessary for cabinet integrity. For the same reason, do
not remove the plugs on the curved side panels or the
bolts in the Community trim bars.

Installation and Assembly Tips
• Test all cabinets before hanging (see expected values at right). Because each
cabinet has multiple LF, MF & HF drivers, it can be difficult to confirm all drivers
are operating properly by simply passing signal through and listening. We
recommend measuring the D.C. Resistance (DCR) of each driver, or driver
pairs, via the input panel(s) using a standard, calibrated Ohmmeter.
• Arrange cabinets in the order that they will hang, and loosely attach appropriate
splay brackets to the bottom of each cabinet.
• Use cardboard or packing blankets to protect grilles and enclosure finish while
units are on the ground .
• Orient cabinets with input panels aligned for ease of wiring; input label text
indicates orientation.
• Leave splay bracket connections slightly loose until all cabinet connections are
made, then tighten evenly according to indicated torque values.
• Have padded wooden materials to support cabinet splay angles if assembling
the array (or parts of the array) on the ground.
• Tools needed: Allen/hex key wrenches (5, 6, 8 mm); #2 Phillips screwdriver.
• Gland nuts are not provided for WR panel covers, holes = 1" (25mm)
- recommended size - 3/4" NPT. Typical 3/4" NPT gland nuts will accept wire
sizes up to 0.875" (22.2mm).
• Pallet jack, fork lift and/or portable lifting equipment are recommended to
facilitate safe assembly.
• When attaching rigging or replacing hardware, please tighten the hardware to
the following torque values: 10mm bolts: 50Nm (36.88 ft-lbs);
12mm bolts: 85Nm (62.69 ft-lbs); 8mm bolts: 25Nm (18.44 ft-lbs).
Do NOT overtighten.
Expected DCR Values (testing)
For LVH900/AS models the DCR for
each input should read approximately:
HF 1+4: ~6 Ohms
HF 2+3: ~6 Ohms
MF 1+3: ~3 Ohms
MF 2: ~6 Ohms
LF 1: ~7 Ohms
LF 2: ~7 Ohms
For LVH900/AP models the DCR on
each cabinet individually should read
approximately:
HF 1, 2, 3, 4: ~12 Ohms each
MF 1, 2 ,3: ~6 Ohms each
LF 1: ~7 Ohms
LF 2: ~7 Ohms
Safety Cable
The safety cable and associated
hardware are not included. Consult all
applicable codes for your application.
Confer with a structural engineer for the
appropriate cable/hardware for the load,
application and locale.
If required, a safety cable(s) must be
secured to a suitable load-bearing point
separate from the array mounting point,
with as little slack as possible, so as
not to develop undue kinetic force if the
primary array mount were to fail.
Splay Brackets, Cabinet Angles and Beamformed Patterns in LVH-900/AP Dual Cabinet Arrays
It is important to remember the beamformed patterns that dual cabinet arrays
can make are distinct and will dictate the splay between two cabinets. The
LVH-900/AP dual-cabinet beamformed patterns require both proper physical
splay between cabinets and appropriate FIR filters applied in the DSP. Two
LVH-900/AP loudspeakers and appropriate splay brackets* are required for each
dual-cabinet array to function properly.
The EASE® Focus report will define any cabinet splay angles in an array.
LVH-900/AP Dual cabinet arrays should be configured using the following splay
plates and hole sets.
LVH-900/AP 20°
SP2 - 30° Back Splay
LVH-900/AP 80°

Splay Bracket Connections (LVH-900SP1)
The angle of the splay brackets should be determined using
EF3 modeling software prior to installation. The report detailing
the positioning of each cabinet in a multi-cabinet array should
be provided by your system designer or integrator. The report
will detail splay angles and bracket types for each of the
cabinets. Refer to Figure 1 for which holes to use to achieve
those angles.
1. Remove at head M10 bolts from the holes where the
splay bracket will attach to the cabinet.
2. Attach the splay brackets to what will be the upper
cabinet - Keep the connections loose so that the next
cabinet can be moved between them. (Figure 2)
IMPORTANT: Do not use power tools to
tighten the bracket hardware - Do NOT
cross-thread or strip these bolts.
IMPORTANT: Splay bracket to cabinet
connections should be symmetrical
Splay Bracket Orientation:
For back splay angles 0-20° the smaller end of the
splay bracket should be at the front of the LVH
For 10-20° front splay angles, ip the bracket so the
larger end is at the front of the LVH.

LVH-900SP2 is used for creating a 30° splay between
cabinets. Most commonly, it is used as the joining plate in an
LVH-900/AP 20° cabinet, creating the proper rear splay angle.
Or it can also be used to create a wide splay at the front of an
array when separation between adjacent cabinets is required.
Please keep cardboard or other cushioning material under the
grilles to protect them from any damage.
1. Remove at head M10 bolts from the holes where the
splay bracket will attach to the cabinet.
2. Attach the splay brackets to what will be the upper
