Introduction And Key Features - Klark Teknik HELIX SYSTEM DN9344 Operator's Manual

Introduction and key features

The Klark Teknik DN9340 Helix equaliser is a two-channel audio 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 whilst addressing a number of limitations in more conventional products.
The Klark Teknik DN9344 Helix Slave equaliser is a 1U slave version of the DN9340 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 DN9344 can be controlled from a master DN9340 unit
or by an external computer, and also has provision for contact closure operation.

Simultaneous availability of graphic and parametric equalisation.
advantages of a dual-purpose unit, this allows the engineer to separate out different sections of
equalisation. For example, during setup and any soundcheck, the parametric mode can be used to set
a basic EQ for the venue, with maximum flexibility. Once the show starts, however, 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, and without
confusion between the `showtime' EQ and the original venue setup. At any time, a quick look at the
home page will show the true overall response of the unit.

Threshold Dependent Dynamic EQ (
have been introduced. These typically resemble a combination of a dynamics processor and an
equaliser. This approach has the disadvantage that whilst it is usually fairly easy to determine the
level at which the dynamic EQ will start to operate, it is much harder to visualise the likely effect as the
system is pushed harder or to set a maximum amount of EQ. The unique
Klark Teknik with its dual thresholds provides unrivalled clarity of operation making this a very
practical tool.

Speed of operation.
more functions into smaller boxes. However, if a function is buried in a hard-to-find sub-menu which
is only accessible after navigating a complex series of button presses, it may as well not be included.
In live production the operation of the unit is as crucial as the sound quality, and this is a key part of the
Helix design. The 2RU format permits a large graphic LCD display, and a second alphanumeric
display provides clear value readouts above the control knobs without using up space on the main
LCD. Dedicated selection buttons for the main functions, clear LED indicators, and no less that 8
separate bargraph meters ensure that the unit is fast and accurate in operation. The unique two-section
touchstrip provides instant access to filters and faders, so that Helix provides the same feeling of being
"in control" familiar to users of Klark Teknik analogue graphic equalisers.
·
Space efficiency.
example, one DN9340 and six DN9344 units would provide 26 channels of EQ, each with graphic,
parametric, and dynamic EQ, plus flexible filters, all in 8U of rackspace.
·
Interface to Midas consoles.
interface is provided which connects to Midas Heritage and Legend series consoles. This allows
the EQ system to be controlled automatically from the solo system of the console, ensuring that
the correct EQ device is always ready for instant access.
