In 1974, brothers Phil and Terry Clark founded Klark Teknik
Research Ltd. In the years immediately following, their
innovative approach to design and development allowed
them to introduce some truly groundbreaking designs. The
world’s first digital delay and digital reverb units emanated
from their laboratory, and their descendants remain in
common usage all over the world to this day. However, it
was their concepts for equalisation devices that really
changed the world of professional audio. Their earliest
designs eventually matured into the world famous DN360
that remains the de facto standard graphic EQ for audio
professionals everywhere.
Today, Klark Teknik continues to uphold the original vision
of the Clark brothers: innovation in design, followed by
uncompromising dedication to engineering and sonic
quality. Most of our units are still made and tested by hand,
a time consuming and labour intensive process that
remains the only method by which we can maintain the
quality that our customers expect. Uniquely in its field, Klark
Teknik also provides the customer with an opportunity to
invest in leading-edge equipment with an extraordinary
working lifespan and unrivalled retained value. Global
support for our products is readily available from the
factory in Kidderminster, from our international distributor
network covering more than 50 countries, and direct from
the Klark Teknik website at www.klarkteknik.com.
Digital loudspeaker system control has been one of the
fastest developing areas of signal processing in recent
years. This is principally because it allows designers to
combine a number of key control functions within a single
device, thereby lowering overall costs and adding
convenience. Unfortunately, in many cases the relevance of
the audio performance of the device has been
overshadowed by the ‘bells and whistles’ functionality of
the unit, ultimately somewhat defeating the object of the
exercise. With the Klark Teknik DN9848, no compromise has
been made in either the feature set or the audio
performance.
DN9848 loudspeaker processor
new levels of flexibility in system control
Unique in that it is the only such device fitted with XLRs to
pack four inputs and eight outputs into a single rackspace,
DN9848 brings a new level of flexibility to system control
whether for live production or installation use. Since there is
no preset routing within the device, it can be easily preprogrammed to perform almost any system-control task.
Limiters and compressors on all outputs plus compressors
on all inputs provide ultimate speaker control and
protection, whilst no less than eighty bands of fully
parametric EQ allow for both room and system
equalisation. Best of all, there’s enough processing power
onboard to allow every function to be available all the time,
regardless of what is already in use.
The proprietary Preset Editor software (utilising Microsoft
Excel) allows simple up-and-down-loading of system
parameters into the FLASH memory locations, as well as
storage and transmission of system information. Need a
new system configuration to be loaded into a unit on the
other side of the world? No problem, put the information
into Preset Editor and e:mail it to wherever it needs to go,
where it can then be uploaded into the unit in seconds.
Online remote control and offline system creation is
provided via the Stardraw Audio system. Whilst it allows
intuitive control of every function of an individual unit or
units, it also (and uniquely) allows inputs and outputs to be
assigned to control groups.These groups can then be made
to control any parameter of the unit or the system – muting,
delay, EQ, dynamics, speaker or room zones, whatever you
need. Simple screens with easy-access controls make for
quick adjustments, and entire system set-ups can then be
stored as a computer file.
All supporting software programs are available free of
charge
from
the
Klark
Teknik
website
(www.klarkteknik.com). A high-quality RS-232 to RS-485
converter (the LBB-485) is also available. This allows
computer connection to DN9848s at greater range than RS232 will support, and is fitted with standard XLR connectors
to interface with regular audio cables.

A natural development from the industry-standard DN360,
DN3600 takes all the best features of Klark Teknik analogue
design and adds digital front-end control.The user benefit of
this hybrid is the traditional warmth and musicality of KT’s
variable-Q analogue graphic EQ, plus memory store and
recall functions, notch filters, hi and lo-pass filters, and
password-lockable system protection.
It also provides the unique ‘auto gain-ranging’ feature that
has made DN3600 so popular with professional users –
simply put, this (defeatable) feature automatically
compensates for the gain change that occurs when a fader
is moved.Thus any EQ curve can be applied to a given mix or
channel, and the output level will remain exactly the same as
the input level. This means that drastic cuts and boosts can
be applied without affecting the gain structure of the
system in any way. It also provides a ‘true bypass’ feature, in
that direct comparisons can be made between ‘EQ in’ and
‘EQ out’ without changing the overall level of the channel.
No other commercially available unit currently offers these
features.
DN3600 system
the definitive programmable graphic equaliser system
The large backlit LCD display is easy to work with, and can
display either virtual fader or actual curve responses. A
single DN3600 can address a system of up to 64 x DN3601
slave units as part of a Pro-Midi loop, and each unit can store
up to 66 user memories.
The DN3601 slave unit is essentially a DN3600 without any
front panel controls, offering all the functionality of the main
unit at a significantly lower cost. Like the DN3600 it can be
addressed individually or as part of a system by a DN3698
handheld remote controller.
The DN3698 handheld remote controller packs all the
functions of a DN3600 into a compact mobile unit designed
for handheld remote access to a DN3600 system. Up to 49 x
DN3600 / DN3601 units can be controlled simultaneously,
giving instant remote access to up to 98 separate mixes.
Mixes can be individually named, copied, compared and
morphed between current and previous selection, and
stored into one of 66 onboard memory locations.
The DN3603 docking station is a 2RU rackmountable device
that performs a number of functions. Firstly it allows safe
rack transport for the DN3688, but it also acts as a MIDI data
dump for storage of program settings from the handheld
remote. It is also the data interface (whether hardwired or
wireless) between the handheld device and the rest of the
system.
The WS01 is a dedicated, bi-directional wireless system that
allows wire-free connection between the DN3698 handheld
remote and the rest of the system. A 2-hour charge will
provide up to 5 hours continuous use, and a working range
of up to 50m is available.

DN360 graphic equaliser
instant access, total reliability, and the greatest sounding analogue EQ
Now approaching some 16 years in continuous production,
the DN360 dual graphic EQ has achieved ubiquity in
professional audio circles. With nearly 30,000 units in the
field worldwide, and the lowest failure rate of any
comparable product, the DN360 even today remains the
dual graphic EQ of choice in most instances. Why is it still so
popular, especially in this menu-driven digital age? The
answer is threefold: instant access, total reliability, and the
great sound of the best analogue EQ money can buy. One of
the main contributors to DN360s audio performance is its
variable ‘Q’ design, meaning that the ‘Q’ value of any fader
becomes narrower as the fader approaches maximum cut or
boost. So rather than a collection of unconnected cuts and
boosts (as provided by a ‘constant-Q’ device) the DN360 user
is rewarded with a flowing, musical response with any
overall fader setting. This proprietary design also allows
every fader to function correctly regardless of the relative
position of its neighbours, another design fault inherent in
‘constant-Q’ units. Each channel also features an
18dB/octave high-pass filter set at 30Hz to eliminate
subsonic ‘rumble’if required, plus an EQ in/out switch and an
overall 6dB / 12dB fader scale switch for normal or high fader
resolution. A design classic, still made as only KT know how.
DN1248
mic splitter
a further dimension of flexibility
Back in 1999, Klark Teknik responded to market demand by
producing exactly what our customers had been
requesting for years – a roadworthy and flexible active
signal splitter system with the superlative audio
performance they’d expect from Klark Teknik. So, DN1248
was born, and also delivered with a host of features simply
not found in any comparable unit.
We specified an internal power supply (with a factory
option of dual auto-switching PSUs at very low cost), more
inputs and outputs per unit than any competitor, a uniquely
flexible solo buss system, and a Midas Heritage-series
microphone preamp, all made available at a per-channel
price appreciably lower than any comparable device. These
features have made DN1248 one of our most successful
units worldwide, but still some customers were not
satisfied. So, once again we have responded to market
demand, hence the introduction of the new DN1248 Plus.
This unit takes all the operational and cost advantages of
the original, and adds a duplicate set of inputs and outputs
to the rear panel.This adds a further dimension of flexibility,
and allows users to upgrade their existing systems with the
minimum of re-wiring. Add in the regular KT 5-year
international factory warranty, and you have a unit that
exceeds the expectations of even the most demanding
users.

DN300/332 graphic equalisers
precision fader resolution
The DN300 and DN332 provide the same industry-standard
audio performance, reliability and variable ‘Q’ topology as
their close relative the legendary DN360, but in two
alternative formats. The single 30-band DN300 additionally
offers swept high and low pass filters with selectable 6dB or
12dB per octave on the low pass, allowing simple control of
extreme high and low frequencies. An EQ in / out switch
and overall level rotary control complete the front panel.
The primary advantage of both the the DN300 and the
DN332 over DN360, or any other 3RU dual graphic, is in the
fader resolution, provided by the 45mm (rather than 30mm)
travel oil-damped precision faders. DN332 packs two 16band channels of graphic EQ into just 2RU. Each channel
has its own overall level control plus an 18dB/octave high
pass filter set at 30Hz for elimination of subsonic ‘rumble’.

DN320/330 preset equaliser
set and forget EQ
Designed specifically as ‘set and forget’ installation tools,
the DN320 (dual 16-band EQ) and DN330 (single 30-band
EQ) bring the unmatched audio quality and reliability of
Klark Teknik to the installation contractor. These low-cost,
high-performance units allow room or system EQ to be
applied, then safely locked away behind security covers
which are integral to the front panel. With the covers fitted,
the untrained eye is unlikely to even recognise these as EQ
units, so further reducing the possibility of unauthorised EQ
access. Failsafe bypass relays are fitted ensuring that signal
passes through the unit even when no power is applied,
making these devices suitable for safety and evacuation
announcement systems. The DN330 is fitted with swept
high and low pass filters and EQ in / out switch, and the
DN320 has a subsonic filter and EQ in / out switch on each
channel. Both units can also be powered from 24v DC
power, so making them ideal for installation in non-fixed
applications such as pleasure boats.

DN422M equaliser with mic preamp
intuitive set up and comparison
Numerous applications require top-notch audio
performance without necessarily needing dozens of
channels of large format mixing console.What’s needed is a
simple but very high quality rackmount front end,
providing the best possible interface between source and
the rest of system. This is where the dual channel DN422M
comes in, featuring two complete Midas XL4 microphone
preamp and EQ sections, each with swept hi-pass filters, 48v
phantom power, mute, pad and phase reverse facilities. The
preamp will accept any incoming level up to +31dBu (with
pad inserted), and each channel is also fitted with frontpanel switchable balanced insert points to allow
connection of other units if required. Output metering and
EQ in / out makes set up and comparison easy.
DN405/410 parametric equalisers
the pinnacle of analogue parametric EQ
Klark Teknik’s international reputation is founded on their
EQ products, and one of the reasons for this is the 400-series
units, DN405 and DN410. Built to stand years of hard use yet
sensitive and accurate, they remain the premier choice of
audio professionals who require the very best in greatsounding analogue parametric EQ.The DN410 is a 2RU dual
channel device, whereas the DN405 is a 1RU single channel
model. Each EQ channel features five bands of fully
parametric EQ, with each band having an active range of
20Hz to 20kHz.This design makes it simple to accurately EQ
out problem frequencies by dialling in a narrow-Q notch
filter then sweeping it across the frequency range. It also
means that EQ bands can be placed very close together or
overlapped if required, unlike some competitive units
which allocate specific frequency ranges to their units. Each
EQ band has an in / out button, and the unit is also fitted
with an overall in / out switch for easy comparison of EQ’d
and non-EQ’d responses.

The DN504 packs four fully-featured compressors into just
1RU, and boasts audio performance equal to its super-quiet
stablemate the DN500. Fitted with hard / soft knee controls,
auto and manual attack / release functions, and side chain
inputs for each channel, the DN504 is especially suited for
in-ear monitoring applications, especially since channels
can be linked as stereo pairs if required. Comprehensive
gain reduction and output level metering completes this
extremely useful and space-saving professional tool.
The DN514 has assumed industry standard status as the
multi-channel frequency-conscious gate unit of choice for
live and recording applications. Providing the same
ultimate audio performance as its 500-series siblings, the
DN514 is extremely comprehensive but easy to set up. Two
semi-automatic attack modes (calibrated for ‘Normal’ and
‘Percussion’) allied with a hold value that is automatically
scaled to the release time, allow each gate to be precisely
configured to its application. It is also fitted with the unique
‘Sync’ function, which locks all four gate release times,
allowing easy synchronisation of harmony parts. Each gate
also features a side chain input, and an additional key input
to allow external triggering if required. LED indicators show
gate status, and both Master (unit) and individual channel
bypass switches aid set-up.

DN500 dynamic processor series
The DN500 dual compressor provides two channels of full
function compression, expansion, limiting and peak
clipping in 1RU. A fully variable knee control allows
continuous definition of compression style, and auto /
manual modes provide either fast set-up or the necessary
control for advanced compression effects. The DN500 has
been a broadcast-industry standard for many years, due
mainly to its extremely low noise performance, typically
>2dB quieter than any comparable product. Expansion
characteristics are continuously variable between hard
gating and gentle expansion thanks to the flexible
expander section, and both compressor and expander
section are fitted with their own side chain inputs. The
channels can be ganged together for stereo operation, and
the peak clipper eliminates transient overload whilst
tracking the limiter threshold for total protection.

means that EQ bands can be placed very close together or
overlapped if required, unlike some competitive units
which allocate specific frequency ranges to their units. Each
EQ band has an in / out button, and the unit is also fitted
with an overall in / out switch for easy comparison of EQ’d
and non-EQ’d responses.
The DN504 packs four fully-featured compressors into just
1RU, and boasts audio performance equal to its super-quiet
stablemate the DN500. Fitted with hard / soft knee controls,
auto and manual attack / release functions, and side chain
inputs for each channel, the DN504 is especially suited for
in-ear monitoring applications, especially since channels
can be linked as stereo pairs if required. Comprehensive
gain reduction and output level metering completes this
extremely useful and space-saving professional tool.
The DN514 has assumed industry standard status as the
multi-channel frequency-conscious gate unit of choice for
live and recording applications. Providing the same
ultimate audio performance as its 500-series siblings, the
DN514 is extremely comprehensive but easy to set up. Two
semi-automatic attack modes (calibrated for ‘Normal’ and
‘Percussion’) allied with a hold value that is automatically
scaled to the release time, allow each gate to be precisely
configured to its application. It is also fitted with the unique
‘Sync’ function, which locks all four gate release times,
allowing easy synchronisation of harmony parts. Each gate
also features a side chain input, and an additional key input
to allow external triggering if required. LED indicators show
gate status, and both Master (unit) and individual channel
bypass switches aid set-up.

DN500 dynamic processor series
The DN500 dual compressor provides two channels of full
function compression, expansion, limiting and peak
clipping in 1RU. A fully variable knee control allows
continuous definition of compression style, and auto /
manual modes provide either fast set-up or the necessary
control for advanced compression effects. The DN500 has
been a broadcast-industry standard for many years, due
mainly to its extremely low noise performance, typically
>2dB quieter than any comparable product. Expansion
characteristics are continuously variable between hard
gating and gentle expansion thanks to the flexible
expander section, and both compressor and expander
section are fitted with their own side chain inputs. The
channels can be ganged together for stereo operation, and
the peak clipper eliminates transient overload whilst
tracking the limiter threshold for total protection.

DN7453/7454 digital delay line
the natural genesis of digital delay technology
As the creators of the original digital delay line more than
20 years ago, Klark Teknik have a long history of designing
and manufacturing innovative products for audio
professionals. The new DN7000-series units represent not
only the leading edge of digital delay technology, but also
the natural genesis of product development.
Although these units (available in 1 input / 3 output and 2
input / 4 output formats) are very high specification delay
units in their own right with an unweighted dynamic range
of >112dB and up to 5.4s of total delay on every output,
they continue Klark Teknik’s policy of offering devices that
provide solutions to more than just one audio problem at a
time.
Every input features seven configurable EQ bands, all of
which can be fully parametric, hi/lo pass or hi/lo shelving.
Every output features six EQ bands, configurable in the
same way. Additionally, every output features a full function
compressor / limiter, and full PC remote control is available
via free proprietary software.
What this adds up to is a versatile ‘audio toolbox’, capable of
condensing the functions of numerous units into one, and
of course providing substantial cost savings in the process.

DN9824 loudspeaker processor
unrivalled flexibility in system control
The rapid advancements in audio DSP (digital signal
processing) technology in recent years have allowed lowercost units to embody many of the functions and qualities of
their top-spec counterparts. Perfectly complementing its
stablemate DN9848 is the new Klark Teknik DN9824,
bringing the great sound and reliability of the brand to the
popular 2 input / 4 output format for the first time, and at a
very competitive price.
The combination of 24-bit Motorola processing and KT’s
proprietary design develops a real-life dynamic range of
>112dB. Comprehensive EQ sections (seven per input and
six per output) can be configured between fully parametric,
hi/lo shelving and hi/lo pass filtering operation, thus
offering full system and room control. All inputs and
outputs also feature up to 900mS of delay allowing system
and individual component alignment, and all outputs have
a full function compressor / limiter for loudspeaker
protection.
Front panel operation is simple and intuitive, whilst free
proprietary PC software allows remote control and system
configuration with online control of all unit parameters.
DN6000 audio analyser
unique analysis functionality
The ability to monitor and analyse audio systems,
regardless of their application, remains one of the most
important issues facing engineers. The DN6000 Audio
Analyser continues Klark Teknik’s long tradition of
providing audio professionals with the tools they need in
the field, with a unique feature set that provides every
important analysis function in one roadworthy device.
Current SPL is constantly shown on a large red LED display,
and measurements may be taken unweighted or with A or
C weighting, in 1/3rd or 1/6th octave analysis modes, and
shown in either peak or average responses. A high-quality
measurement microphone is supplied with every
(individually calibrated) DN6000, for which a front panel
microphone input is fitted. The unit is also provided with
dual line level inputs for stereo 1/3 octave analysis, with
sum and differences display options, to allow it to run ‘inline’ with a system if required.
An internal signal generator with sine wave and band
limited pink noise test signals is also supplied, with the
additional capability to provide test signal burst and
frequency sweeps with automatic data capture, thus
providing numerous system-test options. A proprietary
ribbon-cable interface allows connection to a Klark Teknik
DN3600 for auto-EQ functions, allowing real-time room or
system EQ adjustments as acoustic characteristics change.
Additional functions include RT60 (reverb decay time)
measurement, as well as Leq (average SPL over a given
period) and Let (SPL at a specific point). Test measurements
can be taken over any period configurable between 25ms
and 180hrs, and two separate banks of data storage are
available, 32 locations for frequency analysis and 16 for
time-related measurements. The ability to store, recall,
compare and print this data plus any subsequent
measurements taken thereon makes the DN6000 an
invaluable tool for numerous applications.

old-fashioned analogue crossover fits in? The fact remains
that DN800 still offers some features that make it uniquely
useful, and now at a price that makes it very attractive. It can
be configured in a number of ways, but its most common
application is to provide four mixes for bi-amped monitor

DN1414/LBB100 di devices
ultimate audio performance combined with superlative engineering
A good DI (direct-injection) device is essential in almost any
system. Given that its primary function is to replace a
microphone, the audio performance is critical. They also
need to be extremely rugged, and also capable of providing
flexible operation. The Klark Teknik LBB100 and DN1414 DI
modules both meet these criteria, and more.
The stand-alone LBB100 has assumed industry standard
status in a relatively short time. Built into an incredibly
strong one-piece aluminium extrusion, with connectors out
of harms way at either end, the unit will withstand the
rigours of touring for many years. Powered by 48v
‘phantom’ power, LBB100 is equipped with a 30dB input
pad and a 15dB output attenuator, providing compatibility
for virtually any source to a console. Unusually it also
features an XLR input, designed to allow direct connection
via a regular microphone cable to the DI outputs commonly
found on backline equipment. A fully transformer isolated
XLR output and linked direct output on a jack complete the
device.
The DN1414 multiple DI module brings all the advantages
of the LBB100 to a rackmount format, packing no less than
14 discrete DI boxes into a single 3RU package. 10 channels
are configured as per the LBB100, and the two remaining
channels are arranged in pairs, featuring simple jack in / XLR
out connection for use as single DI units or as stereo pairs.
Customers can specify a factory-fitted dual power supply
option if required, and the unit is also fitted as standard
with a multipin retrofit kit. This allows a user to fit the
multipin connector of their choice to a blank panel on the
rear and then hard wire the outputs direct to it. All this
makes the DN1414 a very flexible device which suits a
number of applications in live production, in the studio and
in broadcast.
