This is a 2RU, dual channel device that condenses all commonly-used EQ functions into one unit, and adds a couple of new ones that are pure KT magic! In one device, you now have access to: a dual 31-band multi-mode graphic equaliser: a dual 12-band parametric equaliser: four configurable filters per channel: up to 1s of delay per channel: and two ‘T-DEQ’ filters, which simply redefine realtime dynamic control. Quite different from frequency-conscious compression, T-DEQ allows the user to dynamically control the amplitude of a given frequency when it reaches programmed upper and lower levels. This unique function has myriad uses, in all sound reinforcement applications. Like all DSP devices from KT, there is more than enough processing power to allow all functions to be active all the time, so you’ll never have to choose a less than ideal solution.

Full time metering is provided for inputs, outputs and T-DEQ functions, and overall the control surface is simple and intuitive to use. Below the main display is a dual touch strip which allows one-step access to various functions, obviating the need to use separate rotary encoders. Helix will also link to DN6000 to provide auto-EQ functions if required, and there is a special bonus for owners of Midas Heritage and Legend series consoles too: by using some simple connections, Helix will provide ‘auto-solo’ functions, so that the channel of Helix assigned to a given input or output will appear in the control surface of a local unit automatically.

The new Klark Teknik DN9340 Helix – a whole new way of thinking about EQ.
