IMPORTANT SAFETY INSTRUCTIONS
EN54-24:2008
RIGGING AND ELECTRICAL SAFETY
Always follow these basic safety precautions when using or
installing R SERIES loudspeakers and accessories:
• Read these instructions prior to assembly.
• Keep these instructions for reference.
• Heed all warnings.
• Follow all instructions, particularly those pertaining to rigging, mounting, hanging and
electrical connections.
• Only use attachments and accessories that are specied and approved by the
manufacturer.
• Refer all servicing to qualied service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, does not
operate normally, or has been dropped.
The terms caution, warning, and danger may be used in this
manual to alert the reader to important safety considerations.
If you have any questions or do not understand the meaning of
these terms, do not proceed with installation. Contact your local
dealer, distributor, or call Biamp directly for assistance. These
terms are dened as:
CAUTION: describes an operating condition or user
action that may expose the equipment or user to potential
damage or danger.
WARNING: describes an operating condition or user
action that will likely cause damage to the equipment or
injury to the user or to others in the vicinity.
DANGER: describes an operating condition or user action
that will immediately damage the equipment and/or be
extremely dangerous or life threatening to the user or to
others in the vicinity.
These servicing instructions are for use by qualied service
personnel only. To reduce the risk of re or electric shock do not
perform any servicing other than that contained in the operating
instructions unless you are qualied to do so.
DANGER: The loudspeakers described in this manual are
designed and intended to be ‘own’ or suspended using a
variety of rigging hardware, means, and methods.
Installation of loudspeakers should only be performed by trained
and qualied personnel. It is strongly recommended that a
licensed and certied professional structural engineer approve
the mounting design. Severe injury and/or loss of life may occur if
these products are improperly installed! All electrical connections
must conform to applicable city, county, state, and national (NEC)
electrical codes.
DANGER: R SERIES rigging ttings are rated at specic
Working Load Limits (WLL) per model line. No single
rigging tting should ever be subjected to a load that is
greater than the stated load. Failure to heed this warning could
result in injury or death!
• R2 models have a WLL of 100 lbs (45.4 kg) with a 10:1 safety margin.
IMPORTANT: Refer to the sections on installation and
connections later in this manual for additional information
on rigging and electrical safety.
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.
DANGER: It is essential that a safety cable (not
supplied) be utilized whenever an R SERIES
Loudspeaker is installed. The safety cable must be
secured to a suitable load-bearing point separate from the
loudspeaker mounting point, with as little slack as possible so
as not to develop undue kinetic force if the mounting bracket
were to fail. Utilize one of the unused threaded mounting
points on the enclosure for this purpose.

RIGGING / SUSPENSION AND SAFETY
TERMINOLOGY: The terms “rigging", “ying" and
“suspension" are often used interchangeably to describe
the installation of loudspeaker systems above ground
level. None of these terms pertain to, or attempt to
describe, the actual method that is used (cables, brackets,
chains, etc.).
DANGER: The loudspeakers described in this
manual are designed and intended to be suspended
using a variety of rigging hardware, means, and
methods. It is essential that all installation work involving
the suspension of these loudspeaker products be
performed by competent, knowledgeable persons who
understand safe rigging practices. Severe injury and/or
loss of life may occur if these products are improperly
suspended.
DANGER: All rigging ttings and inserts must
remain sealed with the included hardware or they
must be tted with properly rated optional mounting
hardware. Any missing fasteners will compromise the
weather resistance of the enclosure.
BIAMP RIGGING HARDWARE WARRANTY:
Biamp warrants that its loudspeaker systems and its
optional mounting and rigging hardware have been
carefully designed and tested. Biamp loudspeakers may
be safely suspended when each loudspeaker model is
suspended with Biamp-manufactured mounting and rigging
brackets specifically designed for use with that particular
model of loudspeaker. This warranty applies only for use
under normal environmental conditions, and when all
loudspeakers, component parts, brackets and hardware are
assembled and installed in strict accordance with Biamp’s
installation guidelines contained herein. Beyond this, Biamp
assumes no further or extended responsibility or liability, in
any way or by any means whatsoever. It is the responsibility
of the installer to insure that safe installation practices are
followed, and that such practices are in accordance with
any and all local, state, federal, or other, codes, conditions,
and regulations that may apply to, or govern the practice
of, rigging, mounting, and construction work in the relevant
geographic territory. Any modifications made to any parts
or materials manufactured or supplied by Biamp shall
immediately void all pledges of warranty or surety, related
in any way to the safe use of those parts and materials.
WARNING NON-Biamp RIGGING HARDWARE:
Non-Biamp hardware used for rigging an R SERIES
loudspeaker must be certied by the supplier for
such use and must be properly rated for safety.
IMPORTANT NOTES ON RIGGING LOUDSPEAKERS
There are three (3) areas of responsibility for rigging
loudspeakers.
• The building structure: Always consult with the building
architect or structural engineer to assure the ability of
the structure to support the loudspeaker system.
• The loudspeaker itself: Biamp certies its loudspeaker
systems and rigging accessories for suspension when
they are properly installed according to our published
guidelines.
• Everything between the loudspeaker and the building
structure and the process of installation: The installing
contractor assumes this responsibility. Loudspeaker
rigging should be performed only by certied rigging
professionals using certied rigging hardware chosen
for the specic application. Prior to installation, the
contractor should present a rigging plan, with drawing
and detailed parts list, to a licensed structural engineer
(P.E.) or architect for written approval.
WARNING: R SERIES rigging ttings are rated at
the Working Load Limits (WLL) listed on page 3. No
single rigging tting should ever be subjected to a
load that is greater than the stated load. Failure to heed
this warning could result in injury or death!
Acceptable Mounting Point Loading
The mounting points should always be used so that either
shear force is applied perpendicular to the direction of and
in tight proximity to the mounting hole, or tension force
is applied perpendicular to the enclosure surface. See
Figure 1 below.
DANGER: Use the mounting points only as
described above. Do not use them in such a way as
to apply sideways leverage to them. Failure to
follow this instruction could result in immediate failure of
the mounting points resulting in damage to the
loudspeaker and serious injury or death to personnel.

INSTALLATION
Before you start
NOTE: Read all instructions and gather tools necessary
before starting the installation. Please read all safety
instructions and warnings regarding rigging and installation
of the loudspeaker.
Every effort has been made to ensure that the information
contained in this manual was complete and accurate at
the time of printing. However, due to ongoing technical
advances, changes or modifications may have occurred
that are not covered in this publication. The latest version of
this manual is always available at biamp.com. The revision
date can be found on the rear cover.
WARNING: Loudspeakers are heavy. To prevent
injury or damage, they should be supported during
the mounting process until the connection is secure.
1. The R2 loudspeaker is shipped with the yoke attached.
If it is necessary to position the yoke dierently, please
remove the mounting hardware and reserve the
hardware for repositioning. Attach the R2 loudspeaker
to the yoke. See Figure 2a. Determine and orient the
loudspeaker correctly for the coverage desired for your
application. Mount the loudspeaker to the yoke with
the rubber washers between the yoke and enclosure
and attach as shown. This is intentionally a tight t to
maintain weather resistance. Tighten bolts to nger
tight (enough to hold the loudspeaker in position).
2. Attach the short at end of the contour strap to the
mounting point located at the back/center of the
enclosure bell using the bolt, rubber washer, at
washer, and lock washer supplied in the mounting
point. Make sure that the rubber washer is between the
contour strap and the enclosure. See Figure 2b. Leave
the other end (the long at end) of the contour strap
temporarily unattached. Eventually this will be attached
to the mounting point below where the yoke crossbar
is positioned when the loudspeaker is mounted and
aimed properly.
The shor t at end of the c ontour
strap goes to the rear and the long
at end shou ld be attach ed to one
of the side mounting points.

is aimed at the appropriate angle. Bend the securing
strap towards the enclosure to put it on the bolt
previously installed on the contour strap. You will have
to bend the securing strap towards the enclosure to put
it on the bolt. First place one of the 1/4" at washers
on the bolt, followed by the securing strap. Finish with
the remaining 1/4" at washer, 1/4" lock washer, then
secure with a 1/4"-20 hex nut.
Attach the 1/4" hardware to the holes
that best match the angle desired

5. Determine the approximate angle of downward tilt
and adjust the angle accordingly. It must be angled at
1/4"-20 SS Hex Nut
least 5° down from horizontal to maintain the stated
enclosure EIEMA rating and reduce the possibility
of rain and other precipitation compromising the
performance. Once the aiming angle is set, bend the
securing strap against the contour strap. The series of
holes in the securing strap should line up with one of

the three 5/16" (8 mm) holes in the contour strap. This
determines where to locate the bolt in the contour strap
to attach the securing strap. Lift the contour strap away
from the R2 enclosure and put the 1/4"-20 x 1" (25 mm)
stainless steel bolt in this hole so that the bolt head is
1/4"-20 SS Hex Nut

WIRING AND ELECTRICAL SAFETY
All standard R-MAX loudspeakers come with attached
SJOW rated input cables, 12' (3.6m) in length. The cable
enters the enclosure through a waterproof gland nut. The
other end of the cable is un-terminated. The designer must
account and compensate for cable losses between the
amplifier and the speaker system. Do not remove the gland
nut attaching the cable to the rear of the loudspeaker, as
this will compromise the weather integrity of the enclosure.
Please contact the Customer Support for additional
assistance (email: support@biamp.com)
1. Wire the loudspeaker. A typical installation method is
to bring the cable into a waterproof junction box (J-box)
equipped with a waterproof gland nut. Connections
within the J-box may be made with barrel-type crimp
connectors, wire nuts, solder and heat-shrink, or
terminal strips. Terminate per your local electrical code.
We recommend using barrel-type crimp connectors
that are crimped with a forged crimp or a ratcheting
tool, as this method, when properly executed, results in
a gas-tight connection that is easy to accomplish.
IMPORTANT: All electrical installation connections
for loudspeaker lines are subject to all applicable
governmental building and re codes. The selection
of appropriate electrical hardware to interface with the
R SERIES loudspeaker lies solely with the installation
professional. Biamp recommends that an appropriately
licensed engineer, electrician, or other qualied
professional identify and select the appropriate conduit,
ttings, wire, etc. for the installation.
DANGER: The output power capabilities of audio
ampliers present a danger to installers. To
minimize the risk of electric shock from loudspeaker
connecting cables, conrm that the power ampliers are
turned “o" before connecting loudspeaker cable(s) to the
loudspeaker or amplier. Always follow local electrical
codes and proper electrical safety procedures.
WARNING: After wiring the amplier(s) to the
loudspeaker(s), rst power-up all devices that are
upstream of the amplier, such as mixers, equalizers,
compressor/limiters, etc., before powering-up the amplier.
This is to avoid passing any clicks or pops that may
originate in the upstream devices to the loudspeakers. The
amplier should initially be powered-up with its gain controls
turned all the way down. After making sure that a continuous
signal is present, such as a CD playing, slowly raise the
level of the gain controls to establish that the wiring has
been installed correctly. Only then should the loudspeaker
be operated at normal output levels.

FINAL ASSEMBLY AND TESTING
1. All holes should be lled with the provided hardware
or other suitable replacement in order to maintain
weather-resistance.
2. Attach a safety cable to an attachment point on each
loudspeaker. The safety cable and hardware are not
included. Please consult a structural engineer for the
appropriate cable for the load and application. The
safety cable attachment points should not be located
on opposite sides of the cabinet in such a manner that
they present a signicant force that pulls the insert
points away from each other. The safety cable must be
secured to a suitable load-bearing point separate from
the loudspeaker mounting point, with as little slack as
possible, so as not to develop undue kinetic force if the
R SERIES mounting were to fail.
3. Power and test the system.
R2-EN Installation and Operation Guide page 7
PERFORMANCE
Use A Digital Signal Processor
For best performance, loudspeaker protection and system
longevity, a digital signal processor (DSP ) should be used
with all R SERIES loudspeakers. Biamp recommends using
Biamp's Amplified Loudspeaker Controllers (ALC) and
ArmoníaPlus software* containing all of the information (high
pass filters, limiters, factory tunings) and DSP settings to
fully optimize your system. For more information on installing
and operating your R SERIES loudspeaker, please contact
our Loudspeaker Support Group at support@biamp.com.
SIGNAL PROCESSING
High and Low Pass Filters
R2 models use fully horn-loaded low frequency drivers.
Refer to the DSP settings files or product data sheets on
the Biamp website for the recommended high and low pass
filter values. Attempts to reproduce significant levels below
these frequencies can result in over-excursion of the low
frequency drivers due to the uncoupling of the low frequency
horn.
The appropriate electronic high-pass filter with a minimum
slope of 12 dB per octave must be employed. Its usage will
protect the drivers from much of the extreme low frequency
content found on media sources. The high-pass filter will
also protect against unwanted low frequency energy that
can originate from microphone wind noise - an important
consideration for outdoor applications.
Power Amplication
Power amplifiers for R SERIES models should be capable
of providing enough power to properly drive the loudspeaker
without the amplifiers entering into a state of clipping.
Clipping occurs when an amplifier runs out of power. The
peaks of the reproduced waveform begin to ‘clip’ and
resemble a square wave instead of the typical sine waves
and saw-tooth waves that form the basis of most speech
and music. Clipping leads to rapid driver failure because the
driver is no longer moving as it’s designed to. When power
is flowing into a driver, but movement is limited because of
amplifier clipping, much of the energy is converted to heat
which will soon cause the driver’s voice coil to burn out.
Power Rating
Refer to the model specification sheets for the recommended
amplifier for each model. It is better to oversize the amplifier
to avoid clipping, than to undersize it. Power amplifiers
should exhibit good sonic properties while providing high
reliability to keep the system functioning properly.
Equalization
Equalization is the icing on the cake for sound systems.
And like the use of icing, it should not be overdone. Small
amounts of frequency boost can brighten-up the higher
frequencies and round out the lower frequencies, but they
should be restricted to no more than approximately +3 dB in
order to avoid damage to the drivers.
Equalization cuts can be very effective for removing the
effects of room resonance and other unwanted acoustical
artifacts, but here again should be kept to a minimum.
Extreme EQ cuts (or attenuation) will not cause driver
damage, but should be used with discretion to avoid acoustic
‘holes’ in the audible spectrum.
External equalization can be used to "voice" the loudspeaker
for particular applications and is especially effective in
attenuating feedback-prone frequencies.
CAUTION: Do not attempt to boost frequencies at,
or below, 40 Hz with an equalizer (either graphic or
parametric). This will counteract the eect of the
high-pass lter discussed previously, potentially
causing damage to the drivers.
page 8 Installation and Operation Guide R2-EN
COMMISSIONING THE SYSTEM
Commissioning is the process of optimizing the
performance of a sound system after it has been installed.
There are several important steps in commissioning a
system; these include the following:
1. Verifying the proper operation of each system
component:
a. Every source such as mixers, microphones, media
players, audio feeds from other locations, and so on,
should be tested independently of the newly installed
system to insure that they are working properly.
b. All ampliers should be tested independently of the
main system to verify that they are each receiving
their intended signal (i.e. HF, MF, LF, delayed, etc.).
Many ampliers have numerous modes in which
they can function. It’s extremely important to make
sure that each amplier in the system has the right
settings applied in order to properly perform its
intended function in the system.
c. The DSP ‘front end’ must be set up carefully to insure
that its internal routing and gain structure are correct
for the overall system requirements. It’s possible to
almost instantly damage mid and high frequency
drivers if the LF, MF and HF outputs are accidentally
crossed.
d. After all electronic components and interconnects
have been tested and veried, it’s then time to test
each loudspeaker element in the system. Such
testing should be performed at VERY low audio
levels to avoid damage to drivers from possible
wiring errors. Each loudspeaker section should
be carefully listened to, in order to make sure it is
performing properly. It should then be checked with
a hand-held phase checker to verify that no phase
errors are present.
2. Next, the gain structure of the system should be
established. Each component in the signal path should
be adjusted to provide the intended input and output
levels. Gain structure is a somewhat complex subject
that goes beyond the scope of this Manual. Moreover,
‘proper’ gain settings vary signicantly from one
device to another. We recommend that you read the
User’s Manual for each device that is present in the
signal path, and adjust according to the manufacturer’s
recommendations, so that your system will operate will
the lowest possible noise oor and highest possible
headroom – which is what gain structure is all about.
3. Set protective limiters and high-pass lters.
4. Set delay times (if any) to align one or more ancillary
loudspeakers with the arrival time of the sound from
the primary source. If delayed speakers are used to
augment the main source, their timing must be set so
that the sound arriving at the listener’s ears from each
delay speaker will be in sync with the sound arriving
from the primary source. This is usually accomplished
with test and measurement instrumentation, but in a
pinch can be set by applying a short duration pulse to
the system and establishing the delay time by ear. An
inexpensive electronic metronome is a good source for
adjusting delay times by ear.
5. Equalize the system to achieve the best possible sound
quality. This last step in system commissioning is known
as system equalization or “voicing.” Equalization is
the process of adjusting the frequency response of
the system, by use of an equalizer, to optimize voice
intelligibility, musical sound quality, or both. Note
that all R SERIES loudspeakers are factory voiced to
optimize speech intelligibility as well as musical sound
quality. For this reason, many designers and installers
nd that they can minimize overall system equalization
and still achieve excellent voice intelligibility and high
grade sonic properties.
R2-EN Installation and Operation Guide page 9
MAINTAINING WEATHER RESISTANCE
SPECIFICATIONS
Guidelines for R Series Outdoor Use
R SERIES is suitable for outdoor direct exposure
installation when used as recommended. For best results
in outdoor applications, follow these guidelines:
• Always orient the loudspeaker so the mouth of the horn is,
at a minimum, pointing at least 5 degrees downward. Failure
to do this could result in water collecting inside the enclosure
under extreme weather conditions.
• When handling an R SERIES loudspeaker, be careful not
to scratch or scrape the nish on the grille, bracket, or
enclosure.
• All mounting holes must be sealed o with the plugs or
stainless steel bolts, washers, and rubber washers supplied.
If, for any reason, the hardware must be removed, seal
o the hole with silicone caulking or some other suitable
weather-tight sealant.
• The gland-nut securing the loudspeaker cable(s) to the
enclosure is sealed at the factory. Do not attempt to remove
this nut or the weather-tight seal will be broken. If you
need to replace the gland-nut with a detachable electrical
connector, such connector must be of a weatherproof design
and sealed to the enclosure with silicone caulk or other
suitable weather-tight sealant. The Neutrik model NL4MP is
an excellent connector for this purpose.
NOTE: The gland-nut should be at the bottom when
installing the loudspeaker. It is also advisable to leave a “drip
loop” so water will not migrate toward the loudspeaker.
• The rubber washers supplied with the mounting bolts must
always seat against the enclosure.
• The grille assembly is designed to prevent normal and
wind-driven rain from directly entering the mouth of the
loudspeaker. The grille is not designed to withstand such
things as being directly sprayed from a hose; therefore this
should be avoided.
• If you use any hardware in place of hardware provided with
your R SERIES loudspeaker, it should also be made of
stainless steel.
CAUTION: If the above instructions are not
observed, the weather-resistant integrity of the
loudspeaker can be compromised. This may result
in damage or failure of the hardware or internal
components which will void the warranty.

long throw full-range sound projection in a
variety of outdoor and indoor applications.
Its wide, smooth frequency response and
high eciency ensures high-fidelity music
reproduction along with superb projection
of clear, intelligible speech at very low
distortion.
The R2-52Z-EN is an all horn loaded
triaxial design using precision waveguides
manufactured by Biamp of hand-laminated
fiberglass. The outer enclosure forms
a double wall construction with the
internal bass horn, providing a completely
weather-sealed chamber for the LF
drivers. The mid/high frequency horn
assembly is mounted in the mouth of the
bass horn. A high quality passive crossover
with dynamic driver protection is included.
The result is a loudspeaker system that is
extremely strong, non-resonant, weatherresistant, and easy to install.
Biamp strives to improve its products on a continual basis.
Specifications are therefore subject to change without notice.

TROUBLESHOOTING GUIDE
SYMPTOM PROBABLE CAUSE WHAT TO DO
No Sound. Equipment is turned o. Check and make sure that all equipment in the audio signal path is
turned on. The amplier should not be turned on until all equipment
before it is turned on.
No Sound. Bad or open connection. Make sure the signal and input wire connections for all connectors
in the system and to all terminal screws are properly connected or
soldered. Make sure all wire and cables are intact and not severed or
damaged.
No Sound. Crossover or all the drivers
have completely failed.
No sound or very low
volume.
Low volume level. System electronic gain is too
Low volume level. Signal or speaker wire
Volume level drops and
comes back.
Sound cuts in and out. Bad connection. Check all connections and cabling for shorts or loose connections.
During high output operation
the volume drops suddenly
and does not come back.
Distortion, low volume, or
no volume from any or all
drivers.
Distortion from the
loudspeaker at higher
volume levels.

The crossover protection
circuits have “given up”.
Cold/open solder joint on

Too little amplier power. If the power rating of the amplier being used is too low, it will clip

Low frequency driver or
crossover is malfunctioning.
This would be an unusual cause but could occur with severe abuse or
an adverse amplier failure. All other possibilities should be explored
before assuming this is the cause. If it is, replace or repair the failed
components.
Check to make sure that the audio signal to the amplier is high
enough to drive it properly. Check all volume/level controls and gain
switches in the system including the amplier input attenuator.
Check to make sure that the audio signal to the amplier is high
enough to drive it properly. Check all volume/level controls and gain
switches in the system including the amplier input attenuator.
Make sure the signal and input wire connections inside all system
connectors are not shorted. Even one small wire strand shorting
the +/- terminals either before or after the amplier can cause this
problem.
This usually means that the loudspeaker is being constantly
overdriven and the crossover protection circuits are reducing the
power to the loudspeaker as a protective measure, which is normal.
Reduce the volume level to the loudspeaker.
This usually means that the loudspeaker was continually overdriven
for an extended period and the protection relays have “fused” in their
protect mode. The crossover must be replaced.
Using an ohmmeter, check the continuity of the crimp connectors,
all solder joints on the crossover and the wiring to the drivers. Also
visually inspect solder joints as cold joints may only malfunction with
higher current than an ohmmeter supplies. Repair as needed.
at higher volume levels. Reduce the volume level or use a more
powerful amplier equal to the loudspeaker’s “Program” power rating.
levels, listen to each driver to isolate the problem. Repair or replace
as needed.
Using an ohmmeter, measure the resistance of the input cable (with
the amplier disconnected). If the meter reads 4–7 ohms, one driver
may not be working. Replace as needed.
