Thank you for purchasing this KV2 Audio, ESR series system, consisting of the ESR3000 stereo controller/
amplifier unit, two ESR215 speakers and optional variants of subwoofers.
The ESR range has been developed for a particular niche in the market, where an all in one box is needed
to give clear detailed reproduction over a wide area. The ESR215 and 212 are three way full range
enclosures with wide dispersion characteristics. They can be used vertically for theatre, church or cultural
centre type installations, or horizontally mounted to give excellent coverage over a tiered seating area for
stadium or grandstand type applications.
Similar to our popular ES range, the ESR cabinets are fully active and driven by a proprietary amplifier,
which delivers equalized, and time aligned accurate signal to each of the components. Two ESR215
cabinets can be driven by a single ESR3000 High Definition Amplifier, which houses all signal processing
and amplification, as well as providing control for two different external subwoofer cabinet configurations
if required.
In situations where extended bass response is not needed, but full range high definition audio
reproduction with extremely good coverage is required, the ESR Range offers an ideal solution. Economies
of scale are achieved by the requirement of only one ESR amplifier, to run a three way active stereo system
where other systems would require processors and multiple amplifiers to achieve a similar configuration.
This manual contains important information on operating the ESR system correctly and safely. Please take
some time and read this manual to familiarize yourself with the advanced features of this system.
The ESR3000 Amplifier is a three-way, active control and amplification system, specifically designed for
the KV2 Audio ESR series loudspeaker systems. It houses all signal processing and amplification, as well
as providing control for external subwoofer cabinet configurations, and to operate additional subwoofer
cabinets if needed. External subwoofers are powered by the external subwoofer amplifier (VHD3200).
The amplifier compliment and configuration inside the ESR3000 Amplifier is as follows:
High Frequency - 100-watt, Class AB, Push pull, Low intermodulation design.
Mid Frequency - 200-watt, Class AB, Push pull, Low intermodulation design.
Low Frequency - 1000-watt, High-efficiency, Current-enhancing switch mode technology with Linear Active
Filter.
In most cases it would be advisable to use a KV2 Audio Line driver (LD4) in addition at the mixer end, to
ensure that the line to the amplifier is driven correctly and the signal integrity maintained.
Although this system is simple to operate, improper use can be dangerous. This is a very high-powered
device that can put out high voltages and sizeable currents. Always use safe operating techniques with the
SL series system.
FOR YOUR SAFETY, READ THE IMPORTANT PRECAUTIONS SECTION AS WELL AS THE INPUT, OUTPUT
AND POWER CONNECTION SECTIONS OF THIS MANUAL.

Cooling
AC Requirements
The ESR3000 Amplifier has a comprehensive cooling system featuring chassis sealed PCB board mounting
and shock mounted, speed controlled fans. This means that the cooling system never drives air across PCB
boards, connectors or components, ensuring prolonged electronic component lifespan and minimizing
maintenance cycles.
Air is drawn into the front of the amplifer by the two fans on the rear panel, this passes over the cooling
fans of the heat sinks and exhausts through the rear. If the heat sink gets too hot, its sensing circuit will
open the output relay, disconnecting the load.
It is important to have an adequate air supply at the front of the amplifier, and enough space around the
rear of the amplifier to allow the cooling air to escape. If the unit is rack mounted, do not use doors or
covers on the rear of the rack, the exhaust air must flow without restriction. If you are using racks with
closed backs, use fans on the rear rack panel to ensure an ample air supply.
NOTE: The filters at the top and bottom of the front panel must be kept clean and free of dust and dirt to
allow full operation - CHECK PERIODICALLY.
Two PowerCon cables are provided to connect the ESR3000 Amplifier to a suitable AC power supplies. Each
cable powers each separate amplifier channel for sufficient current delivery.
CAUTION: The ESR3000 requires a ground connection. Always use a grounded outlet and plug.
The PowerCon is a connector without breaking capacity, i.e. the PowerCon should not be connected
or disconnected under load or while it is live. Always isolate your AC supply before disconnecting the
PowerCon connector.
The ESR3000 amplifier operates in either 115V, 230V or 250V modes. Although pre-configured at the
factory, the unit’s operating voltage mode can be changed in the field. Amplifier power plug must remain
readily operable.
Your amplifier will be supplied preset to the voltage used in your area. The table below provides typical
current draw figures for the ESR3000 Amplifier.
The receptacle must be connected to a fuse or circuit breaker. Connection to any other type of receptacle
poses a shock hazard and may violate local electrical codes.
Do not allow water or any foreign object to get inside the amplifier. Do not put objects containing liquid
on or near tne unit. To reduce the risk of overheating the amplifier, avoid exposing it to direct sunlight.
Do not install the unit near heat-emitting appliances, such as a room heater or stove. this amplifier
contains potentially hazardous voltages. Do not attempt to disassemble the unit. The unit contains no user
serviceable parts, repairs should be performed only by factory trained service personnel.

FULL RANGE MODULE

The ESR215 is a 3-way high output, active-driven,
full range Loudspeaker module. It is designed as
part of a sound reinforcement speaker system
that includes the ESR3000 system control and
amplification system.
The ESR215 Loudspeaker system benefits from
being designed exclusively to operate above 35
Hz. By optimizing the ideal operating band pass of
each system component, the ESR215 can achieve
extremely high output levels consistently and safely.
Active-driven by the ESR3000 unit
Power, electronic crossovers, phase alignment,
equalization, time correction and speaker
protection are provided within the ESR3000 unit.
This“one plug in, one-plug-out” system ensures fast,
easy set up and complete control. It gives you the
benefits of active sound reinforcement technology,
yet locates the electronics in an easy-access
rackmount module.
Together, the ESR215 and ESR3000 unit deliver the
highest dynamic range of any system currently
available, providing new levels of clarity, depth and
resolution.
Advanced compression driver
KV2 Audio’s transducer partner, 18 Sound in
Cavriago, Italy, manufactures and co-develops all
ESR215 components. The compression driver is a
3-inch nitride-titanium diaphragm design, featuring
a complex geometry phase plug that dramatically
lowers distortion, eliminates ring modes and
provides clearer, ripple free performance.
Wide dispersion horn
The ESR215 features a mid/high integrated horn
design with a number of unique features. The horn
design is based on constant directivity geometry
with an emphasis on maintaining low transducer
compression ratios, high output and wide
dispersion (110˚ x 40˚). The midrange speaker with
precisely designed heat sink midrange “chamber”.
The combination provides optimal cone loading
and heat dissipation. Further loading and dispersion
is controlled through A precision phase plug.
Heat-resistant midrange
Midrange frequencies between 400Hz and
2.5kHz are reproduced by eight-inch midrange
speaker that provides 108 dB of sensitivity (1
watt / 1 meter) when coupled with the integrated
horn. The magnetic motor assembly features
a high temperature 3” (76mm) diameter voice
coil assembly and extensive use of neodymium.
Because of the limited linear movement of most
midrange transducers - usually 2-3mm - ventilation
of the voice coil assembly and magnetic structure
is poor and failure rate from heat fatigue is high.
The ESR215 midrange dissipates heat passively
through the use of a massive heat sink midrange
chamber. When combined with the ESR3000 unit
control electronics, the system provides high output
levels safely and consistently over infinite periods
of time and dramatically reducing heat associated
transducer problems such as power compression
and decreased dynamics.
Neodymium bass transducer
The ESR215 features a fifteen-inch ferrite bass
speaker with front loaded bass reflex design. Great
advantage of the ferrite structure is long-term
stability of parametres and relative resistances to
high temperatures.
The ESR215 bass transducer reproduces frequencies
from 35Hz to 500Hz. The bass transducer is very
precise and fast with high sensitivity. The high
efficiency ferrite motor provides an extraordinary
amount of force that delivers complete control of
the cone mass and a high overall weight loss.
Easy to set up
The ESR215 is an aesthetically pleasing - looking
enclosure featuring a number of ergonomically
designed components that make speaker easy to
set up and use.
ESR215 features the two top handles for pick up and
reposition with additional M10 suspensions point.
There are six industrial grade, internal braces
placed at each corner and one internal brace on
the back. Corner braces are held in places by two
M10 bolts, the back brace is held by two M6 and
one M10, providing a wide range of installation and
suspension flexibility.
