Product file
The Klark Teknik DN9340E Helix digital equaliser is a two-channel audio digital equaliser packaged in a 2RU, 19” rack-mounting format. The two channels can be controlled independently as two separate mono equalisers or linked for stereo operation. The unit has been designed to build on Klark Teknik's unrivalled reputation for high quality equalisation, while addressing a number of limitations in more conventional products. The Klark Teknik DN9344E Helix Slave digital equaliser is a 1U slave version of the DN9340E unit. By packaging FOUR channels of Helix processing into a 1U case, it offers unrivalled space efficiency, with a cost per channel lower than many less flexible products. The DN9344E can be controlled from a master DN9340E unit or by an external computer, and also has provision for contact closure operation.
