(1) DN9331 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.
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.
