Service
Thank you for purchasing this KV2 Audio - K-RIG system, consisting of the KPAK2600 controller/amplier
unit, KT2.0 Mid/Hi speakers and one or two KT2.15 subwoofers per side of the stereo system. The
K-RIG system has been developed as a high output, easy to use system, where a competitive price is
important. The K-RIG system has purposely been designed to be used as a ground stack, accordingly the
KT2.0 cannot be used separately without the KT2.15 and K-RIG must be assembled as described in the
enclosed user guide part “Using the system”.
Similar to our popular ES range, the K-RIG cabinets are fully active - driven by a proprietary amplier,
which delivers equalized, and time aligned accurate signal to each of the components. One KT2.0 mid
hi enclosure and up to two KT2.15 subwoofers can be driven by a single KPAK2600 Amplier, which
houses all signal processing and amplication, as well as providing signal outputs for external additional
subwoofer cabinets if required.
Please take some time to read this manual, to familiarize yourself with the advanced features of this
system.
High Frequency - 200-watt, Class AB, Push pull, Low intermodulation design
Mid Frequency - 500-watt, Class AB, High eciency, Switch mode, Low intermodulation design
Low Frequency - 1600-watt, High-eciency, Current-enhancing switch mode with Linear Active Filter
In most cases it would be advisable to use a KV2 Audio Line driver, (LD4) in addition between the mixer
outputs and KPAK2600 Amplier, to ensure that the line to the amplier 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 K-RIG system.
FOR YOUR SAFETY, READ THE IMPORTANT PRECAUTIONS SECTION AS WELL ASTHE INPUT, OUTPUT AND
POWER CONNECTION SECTIONS OF THIS MANUAL.
Your K-RIG System is warrantied against defects in material and workmanship. Please refer to your
supplier for more warranty details.

distributor, service centre or shipped directly to the factory. All warranty and service repairs must be
undertaken by qualied technical personnel. If the unit/s needs to be shipped back to the factory, we
advise using the original packing to reduce the risk of damage in transit. Please contact your nearest
KV2 Audio centre for service details. Distributors list can be found at www.kv2audio.com.

Introduction KPAK2600
KPAK2600
Overview
Introduction

Introductions
The KPAK2600 is a three-way, active control and amplication system specically designed for the KV2
Audio K-RIG loudspeaker systems. It houses all signal processing and amplication as well as providing
control for subwoofer or multiple subwoofers, powered by the internal subwoofer amplier.
Unlike most other speaker manufacturers, KV2 Audio is equally expert in electronic design - in fact,
we’re fty-year veterans at building rugged, high-current power amps. When you’re able to perfectly
match an amp with a transducer, you unlock incredible performance that is not achievable with passive
systems.
The amplier can perfectly handle the impedance swings of the transducer. It can deliver exactly the
right amount and type of power. Reliability goes up dramatically as does sound quality.
Each amplier in the EPAK2600 perfectly complements the transducers it is coupled to.They are therefore
very dierent from each other with respect to construction and purpose.
The High frequency amplier inside the KPAK2600 is Class AB, with Push-Pull amplier circuits using
(MOSFET) Transistor output stage devices. The entire performance strategy for this type of design is
based on producing the lowest inter-modulation distortion possible and the highest audio quality in the
critical mid and high operating bands. The Amplier is coupled to the high driver through a transformer
balanced speaker output.
The Mid frequency amplier is a high eciency design with reduced intermodulation distortion.
With the Low frequency amplier, we’ve selected a very high eciency and rened low frequency
amplier topology. The unique part of the design is in the voltage amplier’s ideal method in supplying
current to the output stage. It’s based on a switcher design that supplies current both in it’s on and o
position and presents superior bass reproduction quality. The system is also 95% ecient, lowering
typical amplier losses and eliminating the need for forced cooling systems.
The amplier compliment inside the KPAK2600 is as follows:
High Frequency - 200-watt, Class AB, push pull, low intermodulation design
Mid Frequency - 600-watt, Class AB, high eciency, switch mode, low intermodulation design
Subwoofer - 1600-watt, high eciency, current-enhancing switch mode with Linear Active Filter
Robust mechanical design.
The KPAK2600 is enclosed in a road-rugged case with two corner handles, aluminium corners and edge
covers. The case has a removable front panel with built-in cable storage compartment.

Cooling
The KPAK2600 uses a standard PowerCon connector. The device must be connected to a suitable mains
socket outlet with protective earthing connection.
The PowerCon is a connector without breaking capacity, i.e. the PowerCon should not be connected
or disconnected under load or while it is alive. Always isolate your AC supply before disconnecting the
PowerCon connector.
Your KPAK2600 will be supplied pre set to the voltage used in your area. The table below provides typical
current draw gures for the KPAK2600.
If the On LED does not illuminate or the system does not respond to audio input remove AC power
immediately. Verify that the voltage is within the proper range. If the problem persists, please contact
KV2 Audio or an authorized service center.
The KPAK2600 has a comprehensive passive cooling system with demand-sensitive forced cooling back-
up, via 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.
It is important to have an adequate air supply around the amplier allow the cooling air to ow. Do not
expose the amplier heat sink to direct sunlight.
If the heat sink gets too hot, its sensing circuit will open the output relay, disconnecting the load.

both the KT2.0 and the subwoofer output for the KT2.15.
4) Harmonics
This level knob serves as a harmonic expander, and adds harmonics to the original sound. This control
serves to optimize performance of poor quality recordings, audio sources and devices. The Harmonics
knob creates more high frequencies from the mid frequencies and ‘lights up‘ the sound, giving an
impression of space and improved intelligibility.
2) Through signal out
Through Signal Output’connector associated in parallel with Main input for sending unprocessed signal
to other devices, such as more KPAK2600’s to power more KPAK2600’s in a system.

The KPAK2600 is designed to actively power one KT2.0 Mid/Hi cabinet and associated one KT2.15 or two
KT2.15 subwoofers in parallel.
The K-RIG System is designed to be used as a ground stack. The KT2.15 subwoofers serve as the base for
the KT2.0 Mid/Hi cabinet and the KT2.0 and KT2.15 cabinets MUST be installed close together.
If the system were installed separately, it negatively aects the sound quality and dispersion because of
the incorrect phase addition of the low mid drivers.
The KT2.0 Mid/Hi can be stacked on the one or two KT2.15 subwoofers.
