KN6 - KN10S

1. INTRODUCTION

KN6 and KN10S are stainless steel, self-powered, 2-way full range speaker systems. Tey

are compact and powerful with multiple D class amplier channels dedicated to each of their

transducer elements. KN6 has a wide 130° vertical coverage pattern and the ability to
select the horizontal coverage from 10° to 130°, making it usable as both a point source and
as a line array element.
The system is ideal for medium throw applications in theatres, concert halls, houses of worship
and AV installations. KN6 uses two 6” Neodymium cone speakers with 2.5” voice coils for
low-mid frequencies. The mid-high frequency section employs three 1” voice coil Neodymium
compression drivers. The transducers are optimized with on-board DSP pre-sets. KN6 is
designed to easily integrate with KN10s selfpowered subwoofer.
The KN10s subwoofer module employs two 10” transducers with Neodymium magnet
structure and suspensions engineered for maximum linear excursion.

All KN6 and KN10S components are designed by the K-array R&D department and custom
made under the K-array quality control system.

• Background music systems in restaurants and clubs

• High-quality distributed systems for paging and music

• Exhibit audio for museum displays

• Space-sensitive ll for theatres

6. SAFETY

WARNING

• It is important that loudspeaker systems are used in a safe manner.

• Professional loudspeakers are capable of producing extremely high sound levels

and should be used with care. Hearing loss is cumulative and can result from levels
above 90dB if people are exposed for an extended period.

• Never stand close to loudspeakers driven at high level.

• Suspending the system should only be done by qualied personnel following safe

rigging practices. Secure xings to the building structure are vital. Seek help from

architects, structural engineers or other specialists if in any doubt.

• Do not operate the speaker for an extended period of time with the sound distorting.

This is an indication of malfunction, which in turn can cause heat to generate and

result in a re.

• Connect the power supply only to an appropriate power adapter.

• Do not install the speaker in wet or humid locations without using weather protection.

• Do not allow water or any foreign object to get inside the speaker. Do not put objects

containing liquid on, or near, the unit.

• To reduce the risk of overheating the amplier, avoid exposing it to direct sunlight.

Do not install the unit near heat emitting appliances, such as a room heater or stove.

• No naked ame sources such as lighted candles should be placed near the device.

• The speaker should be placed so that its location does not interfere with its proper

cooling.

• Do not attempt to disassemble the unit. The unit contains no user serviceable parts.

Repairs should be performed only by factory trained service personnel.

• Be sure that the adapter has the correct voltage value.

8. AMPLIFIER

8.1 AC POWER CONNECTOR

The amplier module and the rest of the audio equipment connected to it (mixing

consoles, processors, etc.) must be connected to the AC power distribution in a
proper way, 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 system’s 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.

8.2 VOLTAGE REQUIREMENT

KN6/KN10S operates safely and without audio discontinuity if the AC voltage
stays within a operating window from 90 V to 260 V.

Check the voltage before connecting the amplier to the AC power.

A higher voltage could seriously damage the device.

8.3 CURRENT REQUIREMENT

The KN6/KN10S presents a dynamic load to the AC mains, which causes the amount

of current to uctuate 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 specications.

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.

12

rev.A

KN6 - KN10S

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 K-array Skin system 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.

8.5 POWER CONNECTORS WIRING

The KN6/KN10S’s ampliers receives DC power from the 3-pin blue PowerCon

connector on their back panel. The white PowerCon connector is a parallel OUTPUT
for supplying power to other devices (max 16A supported). When AC power is
applied to the speaker, the auto-range power supply selects automatically the correct
operating voltage.
For creating your power cables, please use the following wiring diagrams:

brown = hot

blue = neutral

yellow/green =
earth ground

8.6 AUDIO INPUT CONNECTORS WIRING

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 output impedance). A Level Control potentiometer (PAD)
allows different set levels. For creating your signal cables, please use the following
wiring diagrams:

8.7 AMPLIFICATION AND PROTECTION CIRCUITRY

The KN6 and KN10S are powered by the a multi channel high power digital amplier.

KN6: 2 x 250W class D amplier channel + 2 x 20W class A/B amplier channel
KN10S: 2 x 250W class D amplier channel

All the specic functions for the KN6 or KN10S such as crossovers, frequency, phase

response, and driver protection are determined by a DSP processor installed inside

the amplier.

The devices have three different type of audio signal limiter. The Clip limiter, the
average Power limiter and the High Frequency limiter reduce the risk of damaging
the components of the speakers.
A Peak Current Shut Down acts as output stage switching process inhibition that
resets itself after 2 seconds. The tripping point is at 35A.

A temperature protection acts reducing the output stage gain above temperature
level of 85° (temperature on output power devices proximity).

8.8 DSP

The internal DSP allows to choice between four different default presets.
