INSTRUCTION MANUAL
14. Rigging Precautions: When mounting or suspending EAW Commercial loudspeaker
enclosures, it is essential that load ratings, rigging techniques, and special safety
considerations be appropriate for the installation. Use only the mounting/rigging points
on the loudspeaker enclosure intended for this purpose. The user must determine the load
requirements, dynamic loading, and any other contributing factors affecting the loudspeaker
installation. The user must determine the proper design factor for specific applications and
the required load rating of the connection to structure. Comply with all applicable federal,
state, and local regulations.
EAW Commercial strongly recommends the following rigging system practices:
•
•
•
Documentation: Thoroughly document the mounting/rigging design with detailed
drawings and parts lists.
Analysis: Have a licensed structural engineer or other qualified professional review and
approve the mounting/rigging design before its implementation.
Installation: Use personnel experienced and qualified for mounting/rigging loudspeakers
in accordance with and in compliance with all federal, state and local regulations.
DANGER: Loudspeakers should be mounted or suspended only by persons with knowledge
of the proper hardware and rigging techniques. When stacking or pole-mounting
loudspeakers, be sure that they are stabilized and secured from falling over or being
accidentally pushed over. Failure to follow these precautions may result in damage to the
equipment, personal injury, or death.

3. INSTALLATION
Unpacking and Inspection
Visually inspect the outside of the shipping carton and check for any damage. After
unpacking, if you find concealed damage to the loudspeaker, save the packing materials for
the carrier’s inspection, notify the carrier immediately, and file a shipping damage claim.
Although EAW Commercial will help in any way possible, it is always the responsibility of
the receiving party to file any shipping damage claim. The carrier will help prepare and file
this claim.
Mounting Precautions
The mounting bracket provided can be
used for wall mounting the loudspeaker.
WARNING: Installation should
only be done by an experienced
technician. Improper installation
may result in damage to the
equipment, injury or death.
Make sure that the loudspeaker
is installed in a stable and
secure way in order to avoid any
conditions that may be dangerous
for persons or structures:
•
•
Check to make sure that the support surface (e.g., wall, etc.) has the necessary
mechanical characteristics to support the weight of the loudspeaker without the
danger of it falling.
Always use support elements suitable for the material of the wall that will support
the loudspeaker (e.g., screw anchors for bricks, screw anchors for cement, etc.). Due
to various construction methods and materials used today, the hardware for securing
the bracket to the mounting surface is not supplied. Consult a building professional
for the proper mounting hardware before mounting the bracket.
•
•
Before suspending the loudspeaker, carefully check all the components to be used to
make sure there is no damage, deformation, corrosion and/or missing or damaged
parts that could reduce the safety of the installation.
Consult a professional rigger or structural engineer prior to suspending loudspeakers
from a structure not intended for that use. Always know the working load limit of the
structure supporting the loudspeaker. Always make sure that the rigging hardware
minimum rating is at least five times the actual load.
•
Avoid installing the loudspeaker in places exposed to harsh weather conditions.

Horn Rotation Instructions
•
•
•
The high frequency horn can be rotated through 90 degrees to allow you to choose
the best horn pattern for your installation.
From the factory, the horn is set to give a 90 degrees horizontal horn pattern if the
loudspeaker is mounted vertically.
If you mount the loudspeaker horizontally, you can rotate the horn through 90 degrees
to compensate. This is done using a medium phillips screwdriver as follows:
1. Remove all the screws attaching the grille to the
enclosure, and gently remove the grille.
2. Remove the four screws attaching the horn to the
enclosure.
3. Gently pry the horn assembly away from the
enclosure (it may be stuck due to the gasket seal).
Support the horn so it does not drop when it
comes free.
4. Rotate the horn through 90 degrees (the horn is
marked with 60 and 90 on the edges to show the direction
of the pattern). Be careful not to pull on the speaker wires.
5. Reattach the horn to the enclosure using the four screws.
6. Replace the grille and secure the screws holding it to the enclosure.

Loudspeaker Cables
•
Use loudspeaker cables with a minimum
conductor size for the length you need as
listed in these tables. This will minimize
power losses to less than 0.5 dB. The
cable lengths listed are “up to” lengths.
For in-between lengths, use the next larger
conductor gauge. Using larger than the
recommended conductor size is always
permissible. Using smaller than recommended
conductor size will result in higher power
losses.

The recommended conductor gauges are

and smaller Metric WG numbers = smaller
conductors. The Metric WG is equal to ten

times the nominal conductor diameter in millimeters.
For cable lengths over 200 feet / 60 m at 8 ohms, and over 100 feet / 30 m at 4 ohms,
the conductor sizes needed for less than 0.5 dB power losses are rarely practical
for physical and cost reasons. As a practical compromise for these situations the
recommended conductor gauge is 10 AWG or 25 metric.

Precautions
•
To prevent inductive phenomena causing humming or distortion, the speaker cables
should not be run together with electrical energy conductors, microphone cables, or
line-level audio lines.
•
•
Use speaker cables that have markings to distinguish the polarity, such as insulation
or conductors of different colors.
Before using the loudspeaker, carefully check that all the connections have been
made correctly to make sure there are no accidental short circuits that could cause
electrical sparks.
•
Verify that the polarity of the connections to all of your loudspeakers are correct.
When more than one loudspeaker reproduces the same frequencies, but with
opposite polarity, there will be sound cancellations. Therefore, if any of the
loudspeakers are wired so that the +/- connection polarity is reversed with respect
to the others, incorrect reproduction will result. Most notably, the bass response will
suffer. This is especially true when loudspeakers are situated in adjacent positions
where the sound waves readily interact with each other.
VR61 and VR62 – 9
5. OPERATION
Signal Processing
Sometimes external signal processing is desirable to “voice” the loudspeaker to
accommodate particular program material, less than optimum acoustics, feedback control, or
personal taste. For these purposes, use a suitable electronic signal processor. This can be as
simple as a 1/3 octave graphic equalizer or a fully capable DSP (digital signal processor) such
as the EAW Commercial DX810, or the EAW MX8750.
Choosing a Power Amplifier
There is no exact answer to the question of what amplifier size you should use for a
loudspeaker. The loudspeaker power rating in EAW Commercial’s specifications only means
it has passed a standard power test. This provides a rating that can be used as a point of
comparison with other loudspeakers. This rating does not necessarily correspond to the best
amplifier size to use nor is it a measure of a “safe” amplifier size to use. Rather, the amplifier
should be sized according to both the sound levels required and the type of audio signals
that will be reproduced. If you are unsure of how to determine this, consult with a qualified
professional or contact EAW Commercial Technical Support.
Preventing damage to the loudspeaker is a function of operating your audio system so
that the loudspeaker is not stressed beyond its design limits.
Operating Tips
•
•
•
•
Do NOT drive any of your electronic equipment into clipping, particularly the power
amplifiers. This can easily damage the loudspeaker.
If driven into clipping, even an amplifier with a power output rating lower than the
loudspeaker’s power rating can cause damage to a loudspeaker.
Avoid sustained microphone feedback. This can quickly cause failure of high-
frequency drivers.
Avoid extreme boosts on equalizers as these can cause excessive input to the drivers
at the boosted frequencies. Generally, cutting frequencies is preferred to adjust the
frequency response.
•
With appropriate signal processing, your loudspeaker should produce exceptionally
good sound. If it is used in a room with problematic acoustics, there is little you can
do to overcome the room problems with electronic adjustments. Your best solution
is careful placement and aiming of the loudspeaker so most of the sound is directed
only at the audience.
•
•
Most EAW Commercial loudspeakers are capable of sound levels that can be
damaging to human hearing. Take precautions so that audiences are not exposed
to such levels. If you must expose yourself to these kinds of volume levels, wear
adequate hearing protection.
Take care when moving or lifting the loudspeaker. Injury to you or damage to the
loudspeaker can result from careless handling.

7. TROUBLESHOOTING
Loudspeaker difficulties usually fall into one of the following categories. The causes for
each are listed in the most likely order of probability.
No Sound or Low Output
•
Loudspeaker cables or connectors are not wired correctly or are faulty. Check
all cabling, referring to these instructions for the correct connections. The best
way to check a suspect cable is to swap it with a known good cable. Check the
loudspeaker’s input panel to verify correct cable connections.
•
•
Electronic equipment is not turned on, or the level controls are not adjusted properly.
Make sure that all equipment in the signal path is powered up, and that all controls
are set to appropriate levels for normal operation.
Loudspeaker is not working. Connect the loudspeaker cable to a known good
loudspeaker, leaving all equipment set to the same levels. If the problem disappears,
the loudspeaker is probably not working. Contact EAW Commercial Technical Support
for appropriate troubleshooting.
Distorted Sound
•
The power amplifier is clipping. The signal level is exceeding the limits of your
system and you must reduce the level.
•
Other electronic equipment is being over-driven. Ensure that no equipment in the
signal chain is being overdriven. For example: input(s) or summing bus in the mixing
console, equalizers, etc.
•
Driver(s) not working properly. Contact EAW Commercial Technical Support for
appropriate troubleshooting.
Partial Sound (frequency band missing)
•
Incorrect EQ settings in the electronic equipment. Ensure that all EQ settings and
filters on the mixing console, preamplifier, or other equipment are set for normal
operation. Ensure that level controls on electronic crossovers and associated
amplifiers are correctly set, and that all cables and connections for such equipment
are connected and working properly.
•
•
Driver not working properly. Contact EAW Commercial Technical Support for
appropriate troubleshooting.
The crossover network inside the loudspeaker is not working properly. Contact EAW
Commercial Technical Support for appropriate troubleshooting.

8. SERVICE and MAINTENANCE
Maintenance
Usually, your EAW Commercial loudspeaker will not require regular maintenance for
normal use. However, you can do several things to keep your loudspeaker in good operating
and cosmetic condition.
•
•
•
•
Testing: Periodically test your loudspeaker for proper performance. A simple test is
to play a CD through it using well-defined, articulate, wide-range program material.
Listen to ensure all drivers are working properly and for any evidence of distortion or
other extraneous sounds. Test at several volume levels: very low, normal, and high.
Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected
for security, wear, deformation, corrosion, and any other circumstances that may
affect the load-handling capability. Immediately remove from service and replace any
hardware whose load-handling capability may be compromised.
Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt.”
Dust, food spills, or similar contaminants can usually be removed with a cloth
dampened with water, or a mild household cleaner. Avoid using any strong solvents
as this may damage the finish. Turn the amplifiers off before cleaning.
Scratches or Dents in Wood Enclosures: Minor scratches on the enclosure can be
painted over with an outdoor latex paint, or simply a colored in with a “Sharpie” or
artist’s marking pen. More serious gouges or dents should be sanded out, filled with
wood putty, and repainted. Touch-up paint in pints and quarts is available through
EAW Commercial Technical Support.
