4. DN3600 The Klark Teknik DN3600 Programmable Graphic Equaliser is a bl Meh quali uly controltd waman tions 2 Drogrammable band equaliser that combines state of the art audio performa with unprecedented ease of use in a two rack space unit For Graphic further flexibility of the graphic equaliser section the unit also incorporates variable frequency low and high pass filters plus Equaliser two one twelfth octave variable frequency notch filters The proprietary analogue filters are based around the Klark Teknik MELT hybrid filter circuits which offer far greater headroom and dynamic range than is possible using 16 bit linear digital systems Benefiting from revised circuitry these fillers are exceptionally reliable and offer greater stability than discrete design hey are also relatively immune to electromagnetic interference unlike coil based filters Tn order to provide maximum operational flexibility the system includes a switchable Q mode the Low Q setting providing an accurate emulation of the industry standard DN360 equaliser In High O mode the performance emulates the DN27 Featuring a very large backlit LCD display window the DN3600 may store up to 66 equaliser settings Pro MIDI Interfacing facilities are provided allowing several DN3601 slave units 64 maximum to be controlled from a single DN3600 The slave units are electrically identical to the DN3600 but only occupy 1U of rack space and have limited control and di
5. s sweep filters and notches Frequency band selection shall be achieved via 30 individual filter buttons and adjustment via a rotary level control The unit will be able to store 66 equalisation setups and address 64 slave devices via a Pro MIDI interface The unit shall have the capability of interfacing with the Klark Teknik DN60 Spectrum Analys functions er for auto equalising All audio connections shall be via XLR style connectors Inputs and outputs shall be electronically balanced as standard with the option of isolation transformers The unit shall have a failsafe relay bypass facility and be capable of operating from a 110 120 240v 10 50 60Hz AC power source Trade Descriptions Act Due to the company policy of continuing improvement we secure the right to alter these specifications without prior notice RELIABILITY CONTROL Even with the advanced electronic engineering incorporated in this product each unit is given the full backing of Klark Teknik s Reliability Control which proves each product against a specification consistent with highest professional standards Precision components are used throughout and every unit is bench tested and aligned before a burn in period and final performance test a MARK IV company The first name with sound system designers Mark IV Pro Audio Group Mark IV Pro Audio Group Klark Teknik Building 448 Post Road Walter Nash Road
6. splay facilities A 16 pin connector is provided for use in conjunction with the Klark Teknik DNGO Real Time Spectrum Analyser enabling room analysis and equalisation to be accomplished automatically To preserve the immediacy of a conventional graphic equaliser the unit is equipped with a large backlit LCD window which provides a virtual representation of a conventional graphic equaliser as well as the settings of the high and low pass filters and the notch filters The 30 frequency buttons allow instant selection of any filter band for adjustment via the level control The use of multi function buttons for regularly accessed functions has been avoided to enable the unit to be adjusted quickly and efficiently The Actual curve function provides the user with a frequency response curve display based on the combined operation of the graphic shelving and notch filters Both the input and output circuitry is electronically balanced with a nominal operating level of 4dB The input stage is voltage and current matched and gives exceptional noise distortion and CMR performance while the output circuitry is based on the Midas XL3 output stage providing exceptionally high drive capability To maintain the optimum signal to noise ratio and headroom at all equaliser settings the gain control acts on the equaliser sections themselves rather than being a simple pre or post equalisation gain stage Additionally an Auto gain mode is included in
