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 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.
