The Klark-Teknik D N 2 7 A 1/7rd Octave Graphic Equaliser is the successor of the widely acclaimed D N 2 7 . It is a totally professional unit which combines the ease of use and reliability of its predecessor with many new features and improvements, to give uncompromising performance and maximum possible flexibility.
Considerable experience in the field of equalisation coupled with a philosophy of continual research and development, has enabled the realisation of a product
which meets the design criterion; simply the best. Use of the highest quality materials and components is maintained throughout: Precision - ground air-gap
ferrite cores and custom-wound coils are combined to produce the inductors required in each filter; the faders are oil-damped for smooth, positive operation.
The construction is completely dependable and robust, every unit being thoroughly tested both electronically and subjectively before leaving the factory.
The new D N 2 7 A features delayed turn-on, "equaliser" and "total system" bypass, an earth-lift facility, and plug-in p.c.b options.
In 1974, brothers Phil and Terry Clarke founded Klark Teknik Research Ltd. Their pioneering approach to design and development allowed them to introduce some truly groundbreaking designs. One of the worldâ??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 graphic EQ devices that really changed the world of professional audio resulting in the uniquely capable DN370 and the world famous DN360. Today Klark Teknik continues to bring innovation in design, engineering and sonic quality in both the analogue and digital realm of audio signal processing. With the introduction of Show Command, Klark Teknik have an integrated system of hardware, software and Ethernet technology providing full control of loudspeaker system equalisation, management and routing. 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
Equalizers are used in sound recording to equalize the balance between an electronic signalâ??s frequency components, by boosting or cutting the energy of specified frequency bands. Audio equalization is most widely used in sound recording, although it has many other applications beside that of the recording studio. There are a number of different types of Equalizers used in music recording. For example, a simple bass control (or low shelf), is able to adjust the gain of low frequency audio signals, without impacting on other frequencies. High self Equalizers (like a treble) on the other hand, are used to adjust high frequency audio signals only. Parametric Equalizers offers a far greater range of audio equalization functions however. These types of Equalizers are able to make three specific adjustments, something that makes them incredibly versatile. They can be used first of all to adjust the center frequency, and then they can be used to adjust the Q Factor in order to determine how sharp the bandwidth is. Finally, they can also be used to adjust the gain control in order to determine how much a frequency is boosted or cut in relation to frequencies above or below the selected center frequency range. A Graphic Dynamic Equalizer is similar to a Parametric Equalizer, except that these Equalizers are designed to be much more user-friendly. However, they are also less flexible than Parametric Equalizers. Graphic Equalizers employ a bank of filters to cover as many as 30 different frequency bands in the audio spectrum, depending on the model. The center frequency and Q Factor on Graphic Equalizers is fixed, but the level of these can be adjusted.
