The DN9344E Helix series digital equalizer from Klark Teknik is a single rack-space slave version of two complete DN9340E units. By packaging four channels of Helix processing into a compact form, the unit offers huge space efficiency, with a cost per channel lower than many other products. The DN9344E can be controlled from a master DN9340E unit, or by an external computer, and also has provision for contact closure operation.
One of the many great features of the EQ is the ability to have available simultaneously, both graphic and parametric equalization. For example, this allows the engineer to setup a sound check for a particular space, using the parametric mode, with its maximum flexibility. Once the show starts, the engineer can flip to graphic mode, which now starts off from a "flat" baseline. Any problems that need fast attention during the show can now be addressed using the speed of operation of graphic EQ.
Another aspect of the Helix system is space efficiency, allowing exceptionally compact EQ systems to be assembled. For example, one DN9340E and six DN9344E units would provide twenty-six channels of EQ, each with graphic, parametric and dynamic EQ, plus flexible filters, all in just an eight rack-space enclosure.
