To reduce the risk of electric shock, disconnect the from the AC mains before
installing audio cable. Reconnect the power cord only after making all signal connections.
• Connect the to a two-pole, three wire grounding mains receptacle. 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 install the amplifier in wet or humid locations without using weather protection.
• Do not allow water or any foreign object to get inside the . Do not put objects containing liquid on, or near, the unit.
• To reduce the risk of overheating the , avoid exposing it to direct sunlight. Do not install the unit near heat emitting appliances, such as a room heater or stove.
• This 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.

All amplifier modules and the rest of the audio equipment connected to it (mixing consoles, processors, etc.) must be connected to
the AC power distribution in aproperway, preserving AC line polarity and connecting earth ground such that all grounding points are
connected to a single node or common point using the same cable gauge as the neutral and line(s) cables. Bad grounding
connections between speakers and the rest of the audio system may produce noise, hum and/or serious damage to the input/output
stages in the systems electronic equipment.
Before applying AC to any K-array self-powered speaker, be
sure that the voltage potential difference between neutral and
earth ground is less than 5 VAC.
If the Display does not illuminate or the
system does not respond to audio input after
ten seconds, remove AC power immediately.
Verify that the voltage is within the proper
range. If the problem persists please contact
HP Sound Equipment or an authorized
service center.
It is recommend that the supply be operated in the
rated voltage windows, at least a few volts away
from the turn on/off points so that small AC voltage
variations do not cause the amplifier to cycle on and
off.

Connecting a 115V system on a 230V AC Power causes heavy
damages tothe device and serious risk for users .
CAUTION
!
KH15 is default set to be connected to 230 V
AC.
The KH15 operates safely and without audio discontinuity if the AC voltage stays within either of two operating windows:
95-125 (voltage selector on 115 V) or 195-250 V(voltage selector on 230 V), at 50 or 60 Hz.
To use the device on a 115 V AC Power you need, before connecting it, to move the voltage selector's cover, just loosening the two
screws, and to choose the correct use voltage by the red switch. Be sure that both voltage set on the selector and AC Power have
the same value . Always close the voltage selector's cover before connecting the device toAC Power. Change the label that points
out the correct voltage in use.
115-230
Page 7
The KH15 presents a dynamic load to the AC mains, which causes the amount of current to fluctuate between quiet and loud
operating levels. Since different cables and circuit breakers heat up at varying rates, it is essential to understand the types of current
ratings and how they correspond to circuit breaker and cable specifications. The maximum continuous RMS current is the maximum
RMS current in a period of at least ten seconds. It is used to calculate the temperature increase in cables, which is used to select
cables that conform to electrical code standards. It is also used to select the cable size and gauge and the rating for slow-reacting
thermal breakers. The maximum burst RMS current is the maximum RMS current in a period of approximately one second. It is used
to select the rating for magnetic breakers. The maximum instantaneous peak current during burst is used to select the rating for
fast-reacting magnetic breakers
For best performance, the AC Cable voltage drop should not exceed 10% at 115V and 5% at 230V.
The minimum electrical service amperage required by a system of KH15 is the sum of their maximum continuous RMS
current. We recommend allowing an additional 30% above the minimum amperage to prevent peak voltage drops at the
service entry.
The KH15 requires a grounded outlet. It is very important that the system be properly grounded for both safety and proper operation.

The KH15 presents a 10k ohm balanced input impedance to a three-pin XLR connector with the following connectors:
pin1 = Ground
pin2 = Signal +
pin3 = Signal -
The is powered by a high-power 2-channel digital amplifiers (750 watts/ch. RMS) with a total power of 1500 watts. All the
specific functions for the such as crossovers, frequency, phase response, and driver protection are determined by a DSP
processor installed inside the amplifier. All K-array loudspeakers are shipped with the drivers in correct alignment. However, if a
driver needs to be replaced, make sure the replacement is reinstalled with the correct polarity. Incorrect driver polarity impairs the
system performance and may damage the drivers.
KH15
KH15
Use standard audio cables with XLR connectors for balanced signal sources. Make sure that pin 1 (shield) is always connected on
both ends of the cable.
Audio signals can be easy-chained using the loop output connector on the user panel of the . A single source can drive multiple
with a paralleled input loop, creating an unbuffered hard-wired loop connection. When driving multiple in an array, make
certain that the source device can drive the total load impedance presented by the paralleled input circuit of the array. The audio
source must be capable of producing a minimum of not distorted 20 dBV (10-Vrms into 600 ohms). The maximum peak SPL over the
operating bandwidth of the loudspeaker is generated by +4dB input signal (1.230 V. ).
If abnormal noises such as hiss and popping are produced bythe loudspeaker, disconnect the audio cable from the
speaker. If the noise stops, then most likely the problem is not with the loudspeaker. Check the audio cable, source, and AC power
for the source ofthe problem.

This frame describes the state of all the loudspeakers on the net.
The colour of the little rectangles into this frame represents the
status of the loudspeakers. Each loudspeaker has three rectangles.
Here there is the meaning of the rectangle's colour.
Two rectangles on top:
: the loudspeaker is not present on the net.
: one module inside that loudspeaker is
over-temperature.
: all modules inside that loudspeaker
have a good temperature.
: at least one module inside that
loudspeaker is in protection.
: all modules inside that loudspeaker
are working properly.
: if this rectangle is black it means that
the loudspeaker is not responding.
The main causes of this malfunction are
loss of power supply and loss of serial
connection between the hub and the
loudspeaker. Check the hardware. If
this rectangle is black will be black also

The KH15
output
modules are using PowerCon connectors for power supply. It is possible, using the link connector, to have more modules on
the same power supply line. Pay attention to not exceed the maximum powercapability of PowerCon connectors. The Audio
section includes a female balanced XLR connector and a male XLR connector wired in parallel. Thanks to these connectors it is possible
to feed a module and to send the same signal to another one through the LINK connector. It is possible to connect till 30 different modules
in parallel on the same balanced line (with a source of 600 ohm impedance). A Level Control potentiometer (PAD) allows different
set levels. The ground lift switch can help to solve ground loop problems separating loudspeaker groud from signal cable's ground.

SCOPE OF THIS MANUAL
Although this manual contains much useful information on rigging in general, it does not claim to be a comprehensive
resource on the subject. This manual assumes that the owners and/or users of a K-array System are knowledgeable
and experienced in the areas of rigging and flying loudspeaker systems.
The suspension of large, heavy objects in public places is subject to numerous laws and regulations at the
national/federal, state/provincial, and local levels. This manual does not address the specifics of any such applicable
laws and government regulations. This manual details procedures and practices consistent with those generally
acknowledged as allowable and safe in Europe. However, the user must assume responsibility for making sure that
use of any K-array system and its components in any particular circumstance or venue conforms to all applicable
laws and regulations in force at the time.
REGULATORY COMPLIANCE
The design and safe working load ratings of the K-array system, unless otherwise specified, are based on either a 5:1
or 7:1 safety factor. However there are wide variations internationally in the regulations and practices applying to
suspension of sound systems in public places. Government officials in one location may have a stricter interpretation
than another local official, even when operating under the same regulations and in the same legal jurisdiction.
In most touring applications of rigging systems, the touring sound provider is normally responsible for ensuring the
safety of the suspension system only below the attachment point. The safety and suitability of the attachment point is
generally seen as the responsibility of the venue owner or operator. However, this distinction (above the hook
versus below the hook) can be open to interpretation. Touring system operators should double-check to make
certain that attachment points are approved and suitably load rated, and that the points used are those identified as
such by the venue owner or operator.
In any case, K-array systems are intended only for suspension from approved rigging points, each known to have
ample safe working loads margins for the system components suspended below them.
MANY ISSUES OF CRUCIAL CONCERN, SUCH AS THE DETERMINATION OF APPROPRIATENESS AND CONDITION OF
VENUE RIGGING POINTS, CANNOT BE ADDRESSED HERE. THEREFORE, THE USER MUST ASSUME ALL
RESPONSIBILITY FOR THE APPROPRIATE USE OF K-ARRAY SYSTEMS IN ANY PARTICULAR LOCATION OR
CIRCUMSTANCE.
CONSEQUENTLY, USERS OF K-array RIGGING SYSTEMS SHOULD BE PREPARED TO TAKE ADDITIONAL SAFETY
ASSURANCE MEASURES BEYOND THOSE OUTLINED IN THIS MANUAL. IN ALL CASES, IT IS THE RESPONSIBILITY OF
THE USER TO MAKE CERTAIN THAT ANY K-array LOUDSPEAKER SYSTEM IS SUSPENDED IN ACCORDANCE WITH ALL
APPLICABLE NATIONAL/FEDERAL, STATE/PROVINCIAL, AND LOCAL REGULATIONS. SAFETY RESPONSIBILITIES
“ABOVE THE HOOK”
12. SUSPENDING MANUAL
Please read this statement carefully and in its entirety. It contains important information regarding
safety issues, including guidelines for general safe use of rigging systems as well as advisories on
government regulations and liability laws.
As an extra precaution, careful inspection of the attachment points is advised before
flying, particularly in older venues or those hosting frequent events using large sound
and lighting systems.

INSPECTION AND MAINTENANCE
The K array flying systems are an assembly of mechanical devices, and are therefore subject to wear and tear over
prolonged use, as well as damage from corrosive agents, extreme impact, or inappropriate use. Such inspection
includes examination of all load-bearing components for any sign of undue wear, twisting, buckling, cracking, rusting,
or other corrosion. Metal seams and welds should be examined for any sign of separation or deformation. HP Sound
Equipment strongly recommends that written documentation be maintained on each K array flying system, noting date
of inspection, name of inspector, points of system checked, and any anomalies discovered.
REPLACEMENT PARTS
Any component found to be defective, or any safety-related component you even suspect might be defective, should be replaced
with the equivalent, approved part. Parts specific to a K array system should be ordered directly from HP Sound Equipment. No
attempt should be made to substitute what appears to be equivalent or mostly the samegeneric replacements. To the best of our
knowledge, most of these suppliers are reputable and their products are reliable. However, HP Sound Equipment has no way of
assuring the quality of products made by these various suppliers. Therefore, HP Sound Equipment is not responsible for problems
caused by components that were not supplied byHP Sound Equipment.
13. MAINTENANCE
Because of the safety issue involved, users must adopt and ad here to a schedule of regular
inspection and maintenance. In touring applications, key components must be inspected be for
each use.
