1. SAFETY PRECAUTIONS
• Be sure to read the instructions in this section carefully before use.
• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.
• We also recommend you keep this instruction manual handy for future reference.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
CAUTION
When Installing the Unit
• Install the unit only in a location that can
structurally support the weight of the unit and the
mounting bracket. Doing otherwise may result in
the speaker falling down and causing personal
injury and/or property damage.
• Refer all installation work to the dealer from whom
the speaker was purchased. Installation requires
extensive technical knowledge and experience.
The speaker may fall off if incorrectly installed,
resulting in possible personal injury.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately stop operating the speaker and
contact your nearest TOA dealer. Make no further
attempt to operate the unit in this condition as this
may cause fire or electric shock.
· If you detect smoke or a strange smell coming
from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If it is malfunctioning (no tone sounds.)
• Have the speaker unit checked periodically by the
shop from where it was purchased. Failure to do so
may result in corrosion or damage to the speaker
or its mounting bracket that could cause the
speaker to fall, possibly causing personal injury.
When Installing the Unit
• When unpacking or moving a heavy speaker, be
sure to handle the unit with two or more persons.
Falling or dropping the speaker may cause
personal injury and/or property damage.
When the Unit is in Use
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.
• Do not operate the speaker for an extended period
of time with the sound distorting. This is an
indication of a malfunction, which in turn can cause
heat to generate and result in a fire.
WARNING CAUTION

2. GENERAL DESCRIPTION
TOA's ES-5071-95 and ES-5071-65 speaker systems are suitable for use as main speaker in halls or theater
applications.
3. FEATURES
• Both models are 3-way speaker systems employing the "voice-range-per-unit" configuration to cover the
frequency range of the human voice with a single speaker unit. The voice range is reproduced by a mid-
range horn speaker featuring a KEVLAR* fiber cone (speaker diaphragm using chemical fibers).
* KEVLAR is a registered trademark of Du Pont in the United States.
• The speaker's new horn pattern control corrects the inherent tendency of conventional constant directivity
horns to narrow oblique radiation patterns.
• The horn's directivity angle is set for 90° horizontal x 50° vertical (ES-5071-95) over short distances, and 60°
horizontal x 50° vertical (ES-5071-65) over long distances.
• The enclosure features trapezoidal "sides" when viewed in a horizontal installation. The angle of inclination
is optimal for reducing interference in the vertical plane when the short-distance speaker and the long-
distance speaker are vertically joined.
• Both the mid-range and high-range horns can be rotated in 90° steps to permit both horizontal and vertical
speaker installations.
• The speakers can be easily adapted to single, dual, or triple amplification systems with the mode switches.
• The speakers' built-in crossover circuitry has been designed with an emphasis on phase matching at the
crossover frequency for smooth acoustic characteristics.
• Both M5 screw terminals and Neutrik NL4MP (parallel) connectors are used for input terminals. The Neutrik
connectors can be used in both single- and dual-amplification system applications.
• Each side surface features 4-M12 suspension holes, making available a total of 16 suspension holes.
Handles on two trapezoidal sides facilitate carrying and installation of the speaker.
• All speaker units can be easily accessed from the rear of the enclosure.
• The enclosure is finished in leather-tone paint that gives a high sense of quality.

4. INSTALLATION
WARNING
Refer all installation work to the dealer from whom the speaker was
purchased. Installation requires extensive technical knowledge and
experience. The speaker may fall off if incorrectly installed, resulting in
possible personal injury.
When installing, mounting brackets of the type suited to the conditions of the installation place must be
prepared.
• Representative installation examples
Suspend the speaker at its sides. It is recommended that headless bolts be used for installation.
[Single speaker suspension]
[Jointed 2-speaker suspension]
[Vertical suspension]
• Do not use the following suspension methods.
Important: Avoid using only the top panel for suspension.

10. CHANGING HORN DIRECTIVITY ANGLE
Mid-range and high-range horns can be rotated in 90°steps. Use this function when switching from horizontal
to vertical installation or when lining up two speakers symmetrically. Follow the procedures below to rotate the
horns.
1. Remove all 14 screws (M5x10) holding the front
grille in place, and detach the grille.
2. Remove all 8 screws (M5x40) holding the horn
baffle in place, and detach the horns.
3. Remove all 8 screws (M5x40) holding the unit baffle,
and rotate the unit baffle to the desired angle. (The
unit baffle can be rotated without taking it out of the
enclosure.) It is possible to rotate the unit baffle in
90°steps.
4. Retighten the 8 unit baffle mounting screws.
5. Replace the horns, and retighten the 8 horn baffle
mounting screws.
6. Replace the front grille, and retighten the 14
mounting screws.
