dn360-mainDN360

Very occasionally, a design is so correct from the very start that it needs little or no development over many years.

The KLARK TEKNIK DN360 has been in continuous production for over twenty years with only one minor design revision, and is still the most popular analogue graphic equaliser on the planet.

With over 35,000 units shipped worldwide to date, DN360 has achieved ubiquity in pro-audio circles. So why is it so enduringly popular? Like all KT units it is well designed and engineered to very high standards so will handle continuous road use with only minimal service. They are also very consistent, so engineers using units sourced locally all over the world will get the same response every time.

But perhaps most important of all is the way they sound – it’s notoriously difficult to describe sound, but talk to anyone that prefers DN360s to any other graphic and they will use words like ‘musical’ ‘smooth’ ‘responsive’ and ‘great sounding’. Primarily this is because we use proportional-Q filtering, where the ‘Q’ value of the frequency increases as the cut or boost increases. This provides a flowing response at low cut / boost values, but also accurate frequency control at higher values.

dn370-mainDN370

The all-new KLARK TEKNIK DN370 is the latest evolutionary step in a process of design refinement that goes back over 30 years. With DN370 we’ve started from the ground up and produced a unit that is totally without compromise, and one that we believe is the finest professional graphic equaliser in the world today. It also perfectly complements the existing Klark Teknik range of equalisers, both analogue and digital.

Our aim is simply to provide discerning professional users with the best possible solutions for system control. Our market research shows that the graphic equaliser is still the most commonly-used EQ device in fixed and mobile live sound applications, as well as many installations, mainly because the physical user interface provides instant access and controllability in even the most demanding environments. To this end we have completely re-evaluated the role of the graphic EQ, focusing exclusively on providing a new feature set that better reflects the needs of modern users.

Like all KLARK TEKNIK units, DN370 is engineered for a lifetime of hard use and carries our 3-year international factory warranty.

 

klark-teknik-dn530DN530 Creative Quad Gate

With the unrelenting absorption of signal processing into digital mixing consoles, outboard gear now has to contribute something extra special merely to justify its space in the rack. The new DN530 Creative Quad Gate does just that. It brings some exciting new tools to the audio party. The DN530 features “Transient Accenting”, a creative feature providing an easy way to enhance the attack envelope beyond merely opening the gate. This can provide up to 12dB of additional transient energy and its primary application is to provide additional impact on drums and percussion instruments, although it can be used to enhance the impact of many instruments, including acoustic stringed instruments such as guitar and piano.

Transient Accenting is unique in that it allows the operator precise control over the amount of enhancement applied to each channel of processing.

The DN530 brings a creative flare to drum channels with its unique accent feature which largely eliminates the need for excessive EQ or compression.

 

dn100-mainDN100

The new KLARK TEKNIK DN100 Direct Injection Box is the natural successor to the long-established LBB100.

A ground-up redesign provides an extended dynamic range, lower noise floor and all the world-class audio performance you’d expect from KLARK TEKNIK. DN100 is also designed to handle the rigours of life on the road: a thick aluminium shell protects the electronics, and this in turn is protected by a tough silicone rubber casing, which is replaceable and available as a spare part.

We’ve also fitted a Kensington security slot in one of the end panels to allow the unit to be made secure using a Kensington MicroSaver security cable.

Attention to detail – it’s what makes a good unit into a great one.

 

Klark_Teknik_dn9696DN9696

The concert sound industry is constantly evolving. Bands and artists are increasingly being recorded for live CDs, DVDs, Internet releases and for general archive purposes; all are extremely valuable additional revenue streams for both the artist and service companies alike.

Secondly, with limited production rehearsals now being the norm, mix engineers require live recordings so that a “virtual sound check” can be performed. This removes the need to directly involve the artist, and all the associated additional expense and time that a traditional sound check or rehearsal process incurs. The “virtual sound check” also allows the mix engineer the time to fine tune his mix and use the full potential that digital console automation offers.

To help meet the concert sound industry’s requirements, KLARK TEKNIK has engineered an extremely easy to use, simple to setup, standalone hard disk recorder – the DN9696. This High Resolution Audio Recorder offers 96 tracks of 96kHz audio at 24bit, with a massive nine hours of internal storage. There is now no need for external computers linked to multiple non-roadworthy systems with complicated interconnections, just a
simple plug and play unit with dedicated Play, Stop and Record front panel transport controls.

The screen based software interface offers in-depth control of both recording and playback functions. There are echoes of the unique features of MIDAS’ digital audio systems within the DN9696, for example the use of POPulation groups to view, colour and edit tracks, an ‘Input Sheet’ for quickly naming all tracks as well as ‘dual operator’ control of the system.

The DN9696 occupies only 5U of rack space with very simple cable requirements and does not demand the expense of a dedicated recording technician. After all, all you really need is Record, Stop and Play.

dn9331DN9331 Helix Rapide

Unique, immediate and tactile, the DN9331 Helix RAPIDE offers direct access to all of the graphic equalisation functions of Helix digital equalisers.

Instant recall of fader positions is made possible by the use of thirty one console-quality 100 mm long travel high resolution motorised faders. These are custom manufactured to KLARK TEKNIK’s exacting standards, featuring long life conductive plastic tracks and driven by fast acting precision servo control circuits. A generously specified power supply ensures high speed of response, and can supply the peak currents required by simultaneous multiple fader movements, without the lag effects experienced with lower-grade remote fader units.

Integrating a MIDAS/KLARK TEKNIK STS Solo Tracking System interface, the Helix RAPIDE is ideal for use in stage monitoring systems. When combined with a MIDAS Heritage, Legend, Siena or XL8 Live Performance System, the solo buttons on each aux send can be used to instantly recall the graphic equaliser settings of the connected channel of Helix digital equalisation. This offers the monitor engineer unparalleled speed of access in situations demanding an immediate response.

A flexible user interface allows custom remote channel assignments across four banks of 32 channel selection buttons. Four freely assignable group buttons and a global ‘all channels’ button allow relative adjustment of channels, especially important when the priority is to stop on-stage feedback first, and determine the source second.

The Helix RAPIDE is the networking centre of the Show Command System. An eight external port Ethernet hub is incorporated into the device, allowing the connection of Helix digital equalisers and system processors, with wired or wireless connections to laptop or tablet PCs running the Elgar Helix EQ RCS and System Controller RCS.

The Helix RAPIDE is fully backwards-compatible with the original Helix DN9340 and DN9344 digital equalisers which may be interfaced using Ethernet-to-serial converters.

 

dn9848DN9848E

The digital system controller 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 new KLARK TEKNIK Helix DN9848E system controller, no compromise has been made in either the feature set or the audio performance.

The Helix DN9848E 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 ninety-six 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 DN9848E System Controller features AES/EBU digital inputs as standard. Whilst the internal sample rate of the DN9848E unit remains at 48kHz, these digital connections are all 96 kHz compatible allowing easy interface with any other digital device featuring the higher sample rate. The unit now features a dual port Ethernet communications interface. This is to facilitate much faster communication, response and metering when controlling multiple units, than was previously possible with serial comms.

The DN9848E incorporates some customer-requested operational additions. The user-configurability of the unit includes full matrix mixing capability between inputs and outputs, providing an unequalled level of flexibility. Whilst programming, inputs or outputs can now be ‘ganged’ so that the user can enter program data into one input or output menu and all connected inputs or outputs will be simultaneously updated. Input and output parameters can also be copied from one to another. The internal memory structure has also been revised such that it is now possible to back up the RAM-based system memories into non-volatile flash memory.

The proprietary ELGAR software coupled with Helix System Controller Remote Control Software (RCS) Add-In allows simple up-and-down-loading of system parameters into the FLASH memory locations, as well as storage and transmission of system information.

Should for example you need a new system configuration to be loaded into a unit on the other side of the world? No problem, simply email the ELGAR file to wherever it needs to go, it can then be uploaded into the unit in seconds.

 

DN1248 DN1248 Plus

Even in this digital age, we’ve kept sight of the numerous applications where analogue devices provide the best solution. One such application is providing multiple feeds from a single source, hence the introduction of the DN1248 Plus Active Signal Splitter.

Housed in a roadworthy 3RU chassis with internal power supply, a single DN1248 Plus provides twelve input channels, each feeding four outputs, two of which are electronically balanced and two which are transformer isolated.

On the rear of the unit can be found output 4, plus duplicates of all the inputs and output 1, so the patching options are extremely flexible. The microphone preamplifier is a MIDAS Heritage series unit, specially adapted to the task and providing all the great sound and headroom for which MIDAS preamps are world famous.

Several factory options are available for DN1248 Plus: the ‘DP’ option, which provides (at very low cost) a second, linked internal PSU to provide auto-backup in the case of PSU failure.

The ‘AT’ option provides transformer balancing for all 48 outputs, and the ‘FM’ variant combines both ‘DP’ and ‘AT’ advantages. Plus, the whole unit is designed so that a customer can easily retrofit the multipin connector and input / output configuration of their choice.

Software

Helix DN9340E and DN9344E EQ Remote Control Software (RCS) Add-In allows remote PC access to all the functions of Helix EQ, including overall system store and recall. An extremely intuitive Graphical User Interface (GUI) allows simple navigation between function pages. The system is designed to work with all PCs including the latest hand-held PC tablets for ease of wireless connection and portability.

Real time indication of unit on-line / off-line status is visible on all pages and the individual function pages have familiar and easy to use controls whether using a mouse, keypad or stylus. The make or break of this type of system is always navigation, and this is one of the Helix EQ RCS’s real strengths, using our proprietary ‘FastNav’ page. This is a control panel that is always active, and shows every function of every channel. Thus it is possible to move between, for instance, the graphic EQ for channel 10 and the T-DEQ controls for channel 37 with a single click.

Helix DN9848E System Controller Remote Control Software (RCS) Add-In provides on-line remote control and off-line system configuration, either via wired or wireless Ethernet technology. The remote control software 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 an ELGAR computer file.
