stoves, or other apparatus (including amplifiers) that produce heat
• Do not defeat the safety purpose of the polarized or grounding plug.
A polarized plug has two blades with one wider than the other. A
grounding plug has two blades and a third grounding prong. The wide
blade or the third prong is provided for your safety. If the provided plug
does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
• Only use attachments/accessories specified by the manufacturer.
• Protect the power cord from being walked on or pinched
particularly at the plugs, convenience receptacles, and at
the point where they exit from the apparatus.
• Clean the product only with a soft and dry fabric. Never use
liquid cleaning products, as this may damage the products
cosmetic surfaces.
• Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use
caution when moving the cart/apparatus combination to avoid injury
from tip-over.
• Unplug this apparatus during lightning storms or when unused for long
periods of time.
• Avoid placing the product in a location under direct sunlight or near any
appliance that generates UV (Ultra Violet) light, as this may change the
product surface finishing and cause a change in color.
• Refer all servicing to qualified service personnel. Servicing is required
when the apparatus has been damaged in any way, such as power-
supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
• CAUTION: These servicing instructions are for use by qualified service
personnel only. To reduce the risk of electric shock, do not perform any
servicing other than that contained in the operating instructions unless
you are qualified to do so.
• WARNING: Only use attachments/accessories specified or provided
by the manufacturer (such as the exclusive supply adapter, battery, etc.)
Installation and commissioning may only be carried out

Pinnacle-KR is a line of integrated, self-powered
loudspeaker systems composed of Thunder-KS
subwoofers and top line array loudspeaker elements from
the Kobra, Python and Kayman series.
Taking advantage of the modularity of the systems and
thanks to the available accessories for ground stacking or
suspending the loudspeakers, the Pinnacle-KR systems can
be assembled in many configurations suiting any application:
from outdoor light parties to auditorium, from conference
rooms to beach clubs and more.
Enhanced performance and easy tuning are now managed
by the Integrated Electronic Brain – IEB – implemented into
K-array amplifiers. More than a traditional DSP, the built-
in micro electronics driven by the integrated operating
system osKar features extensive sound processing, offering
complete user control over the system performance:
Volumes, Signal Routing, Presets as well as a complete USB
player, are directly manageable from the device via mobile
app and dedicated professional interface.

Unpacking
Each K-array product is built to the highest standard and
thoroughly inspected before leaving the factory.
Upon arrival, carefully inspect the shipping carton, then
examine and test your new device. If you find any damage,
immediately notify the shipping company.
Each Pinnacle-KR configuration is a bundle composed of a
set of elements optimized to reach the desired performance,
according to the application. Extended performance
can be achieved by adding more elements to the factory
configurations as well as combining more bundles, making
the Pinnacle-KR a scalable solution tailored to the contest.

Assembly: ground stack
1. Screw the K-JOINT3 hinge arms to the column
loudspeaker(s) (see “Joint”, page 4).
2. Set firmly the Thunder-KS subwoofer on a even
horizontal surface.
3. Assemble the K-FOOT3 on top of the Thunder-KS
subwoofer (see “Ground Stack”, page 5). The
Pinnacle-KR102 II system is provided with a pole

be screwed directly on top of the subwoofer.
4. Join the first loudspeaker to the K-FOOT3 – or to the
K-KKPOLE according to the Pinnacle system model –
(see “Joint”, page 4).
5. If available, join the further loudspeakers to the one
already assembled on top of the subwoofer.
The total height of the column loudspeakers
shall not exceed 2 m (6.6 ft),
i.e. no more than two meter-long units shall be
stacked on top of the subwoofer.

AC mains supply
The AC Main connection is made via the provided power
cord: insert the powerCon TRUE flying connector into
the Thunder-KS active subwoofer inlet and then rotate it
clockwise.
Once properly plugged, the active subwoofer power up: the
back LEDs light on.
The powerCon TRUE link (AC mains out) connector allows
to distribute the AC main power to one further active unit.
Loudspeakers Wiring
The Thunder-KS active subwoofers features two NL4
speakOn output connectors designed to drive external
Hi/Mid-range loudspeakers as well as other subwoofers or
full-range passive loudspeakers systems.
A single loudspeaker system is composed of one Thunder-KS
active subwoofer and one or more top loudspeakers. An
active + passive loudspeakers system is composed of one
Thunder-KS active subwoofer driving both one or more top
loudspeakers and one passive Thunder-KS subwoofer with
satellites (top loudspeakers).
Please don’t exceed the limit of two Thunder-KS
active units linked and powered by the same line.
The proper loudspeaker presets shall be
loaded in the built in DSP using the dedicated
K-array Connect app or the K-framework3 software
BEFORE routing any audio signal to the output channels.

1. Ensure the Wi-Fi of the mobile device is on.
2. Launch the K-array Connect app.
a. In Android based systems the app looks for any
Wi-Fi network whose SSID name starts with
“K-array”; swipe down to force refresh the list of
available networks.
b. Touch the device name to estabish a connection
and insert the password (see below).
3. If the list of available devices is empty touch the SCAN
QR CODE button and use the mobile device camera
to frame the QR code at the top left corner of the
Thunder-KS rear panel: this provides the mobile device
to connect to the Thunder-KS Wi-Fi network.
4. Enter the password to connect to Thunder-KS active
subwoofer. If not modified, the default password is
the device serial number, e.g. K142AN0006 (case
sensitive).
5. The K-array Connect app connects directly to the
Thunder-KS active subwoofer.
* The on-board web interface is a further user interface embedded on the
built-in DSP that allows to manage the system features over a network (see

Connection to a network of Thunder-KS
The Thunder-KS active subwoofers feature a RJ45 Ethernet
port on the rear panel that allows to connect the loudspeakers
to a local area network (LAN), in order to ease the remote
control.
The Thunder-KS implements the zeroconf network
technologies, allowing to direct connect the active subwoofer
to a PC via the Ethernet CAT5 cables, as well as including the
devices into a network without any user configuration.
The simplest local network of Thunder-KS active subwoofers
requires the implementation of an Ethernet switch. When an
access point is available, the network of Thunder-KS active
subwoofers can be easily managed with the K-array Connect
mobile app over the LAN.
1. Connect each Thunder-KS active subwoofer to a Wi-Fi
access point with built-in Ethernet switch: use Ethernet
Cat5 or Cat6 cables.
2. Set the access point Wi-Fi network SSID and parameters.
3. Ensure the Wi-Fi of the mobile device is on.
4. Connect the mobile device to the access point Wi-Fi
network.
5. Launch the K-array Connect app: the app looks for any
device in the network whose name starts with “K-array”
and tries to establish a connection.
6. If the list of available devices is empty swipe down to
force refresh the list of available devices.
If a DHCP service is available, it will assign an IP address to
each Thunder-KS. If a DHCP service is not available, each
Thunder-KS active subwoofer will self assign an IP address
in the range 169.254.0.0/16 (auto-IP).
