31 Band Motorized Fader Graphics Controller
Year 2009
Delivered without flight case
Revised and checked

Unique, immediate and tactile, the DN9331 Helix RAPIDE offers direct access to all of the graphic equalisation functions of Helix digital equalisers.
Instant recall of fader positions is made possible by the use of thirty one console-quality 100 mm long travel high resolution motorised faders. These are custom manufactured to KLARK TEKNIK’s exacting standards, featuring long life conductive plastic tracks and driven by fast acting precision servo control circuits. A generously specified power supply ensures high speed of response, and can supply the peak currents required by simultaneous multiple fader movements, without the lag effects experienced with lower-grade remote fader units.
Integrating a MIDAS/KLARK TEKNIK STS Solo Tracking System interface, the Helix RAPIDE is ideal for use in stage monitoring systems. When combined with a MIDAS Heritage, Legend, Siena or XL8 Live Performance System, the solo buttons on each aux send can be used to instantly recall the graphic equaliser settings of the connected channel of Helix digital equalisation. This offers the monitor engineer unparalleled speed of access in situations demanding an immediate response.
A flexible user interface allows custom remote channel assignments across four banks of 32 channel selection buttons. Four freely assignable group buttons and a global ‘all channels’ button allow relative adjustment of channels, especially important when the priority is to stop on-stage feedback first, and determine the source second.
The Helix RAPIDE is the networking centre of the Show Command System. An eight external port Ethernet hub is incorporated into the device, allowing the connection of Helix digital equalisers and system processors, with wired or wireless connections to laptop or tablet PCs running the Elgar Helix EQ RCS and System Controller RCS.
The Helix RAPIDE is fully backwards-compatible with the original Helix DN9340 and DN9344 digital equalisers which may be interfaced using Ethernet-to-serial converters.

Architect's & Engineer's Specification
The digital graphic equaliser remote controller shall offer control of 31 bands of KLARK TEKNIK Helix graphic equalisation and have 31 motorised 100 mm faders representing frequencies from 20Hz-20kHz on 1/3 octave centres to BS EN ISO 266:1997.
The unit shall be contained in a 6U 19” rackmount enclosure, which shall be so designed as to also allow the unit to perform as a freestanding console.
The unit shall provide remote control of up to 64 channels of KLARK TEKNIK Helix graphic equalisation. The remote control interface shall be via Ethernet and there shall be an Ethernet switch integrated into the unit with eight external ports fitted with Ethercon connectors. There shall also be a rear panel RS-232 port provided for remote control from MIDAS Heritage, Legend and Siena mixing consoles, which implements the KLARK TEKNIK and MIDAS Solo Tracking System control.
The user interface shall provide for four banks of 32 channels of user-assignable channel access, implemented as four bank and 32 channel non-latching illuminating pushbutton switches. There shall be four non-latching illuminating pushbutton switches provided for the selection of groups, each of the four groups permitting the relative adjustment of multiple channels of Helix graphic equalisation.
There shall also be a non-latching illuminating pushbutton for global access of all addressable channels of Helix graphic equalisation and applying relative adjustment to all channels. A non-latching illuminating pushbutton shall also be provided to bypass the currently selected channel(s) of Helix graphic equalisation. Eleven-segment LED bargraph meters shall be provided for monitoring the input and output audio signal levels of an individual channel.
A 20 x 2 alphanumeric LCD display shall be provided for the display of parameter information and three rotary encoders shall be provided for parameter adjustment. Momentary pushbutton switches shall be provided for memory store and recall and setup menu access.
The unit shall be capable of operating from a 90 to 250V, 50 to 60 Hz a.c. power source.
The unit shall have a 1U space above for ventilation.
The digital graphic equaliser remote controller shall be the KLARK TEKNIK DN9331 Helix RAPIDE, and no alternative specification option is available.
