Klark Teknik DN9340E 2CH Digital EQ and Delay


  • Model: DN9340E
  • Manufactured by: Klark Teknik

Helix Dual graphic / parametric / dynamic equaliser and delay

The concept of an equalisation device which allows the user to not only select from a menu of various EQ types but also to integrate them with each other in any combination is one that could only have come from Klark Teknik. At the heart of Helix DN9340E is the fact that it sounds incredible.

For the uninitiated, the new Helix DN9340E is a dual channel, 2RU, all-digital equalisation unit that simultaneously offers a five-mode 31-band graphic EQ, twelve bands of full parametric EQ, four configurable filters (HPF, LPF, hi shelf, lo shelf and notch) and two bands of true dynamic EQ (T-DEQ) per channel.

Unit control is provided by both a touch strip and rotary controls, full input and output metering is provided plus dedicated meters for the T-DEQ function. A large, bright LCD display provides visual reference for all functions and the entire menu structure is simple and intuitive. Helix can also be linked to Midas Siena, Legend and Heritage consoles via the Solo Tracking System (STS): this allows any channel of connected Helix EQ to be edited from the control surface of a single Helix DN9340E unit or PC simply by activating the appropriate PFL function on the console (STS only works on the outputs of the Siena).

By linking a DN9331 RAPIDE to the DN9340E it allows the user to have instant control over the Helix 31 band graphic EQ function thanks to the unique 31 Klark Teknik 100mm motorised faders fitted to this unit.

The Helix DN9340E also features AES/EBU digital inputs and outputs as standard, complete with word clock sync inputs. Whilst the internal sample rate of all DN9340/44E units remain at 48kHz/44.1kHz, these digital connections are all 96 kHz compatible allowing easy interface with any other digital device featuring the higher sample rate.Secondly the Helix DN9340E unit also features a dual port Ethernet communications interface. This is to facilitate much faster communication, response and metering between units than was previously possible with serial comms. The Ethernet ports allow for control of the units from a PC, either via Ethernet or wirelessly with the Helix EQ Remote Control Software (RCS) an ELGAR Add-In.
