Operation DN9340: Filters Select filters by pressing the FILTERS key. The display for the filters is similar to the home page, showing the frequency response - in this case just for the filters.At the top right is a legend “Filter 1 of 1” which indicates which filter is currently active for control, and also how many filters are in use.
Page 35
Filter settings page · Filter type - available types are Notch, Low Pass (normal and peaking), High Pass (normal and peaking), Hi Shelf and Lo shelf. · Graph display - three modes are available, to ensure that clear information is available for any application.
Operation DN9340: Storing and recalling settings The Helix unit includes two types of memory location, to provide maximum flexibility in a range of applications. There are 64 user memories in battery-backed-up SRAM, and also 32 preset memories in non- volatile FLASH memory. Recalling settings from either memory type uses the same procedure, and the user memories can be stored directly from the front panel of the unit.
Operation DN9340: Setup menu The Setup menu provides access to the options and configuration settings for the unit. It is accessed by first selecting the HOME(SETUP) key to go to the home page, then pressing and holding the HOME(SETUP) key for one second.
Operation DN9340: Metering Comprehensive audio metering is provided by eight LED bargraph meters. There are a pair of input meters (labelled A and B for audio channels A and B respectively), which show the input level immediately following the input gain control. These can therefore be used as a guide for setting the input gain to match the signal level being sent to the unit.
Operation DN9340: Clear down sequence Because of the comprehensive facilities available on the DN9340, it may be important to ensure that the unit is “cleared down” before use. Remember to clear down both channels A and B if the unit is not linked for stereo operation.
Remote Control: The Basics Connections A DN9340 master unit can control both DN9340 and DN9344 units as slaves. In order to set up a remote controlled Helix system, first connect the units together using the RS-485 connectors on the rear panel. The units are connected in sequence from output to input, in any order.
Page 41
Remote Control Once all the slaves have been set up, the master unit can be set on-line. Again, it must have a communication channel allocated, which must not be the same as any of the slaves. Press HOME(SETUP). Press and hold HOME(SETUP). The left encoder lights, to show that it is active.
Page 42
Remote Control The following name fields can be edited: This 20-character name will be used on the master unit to indicate to the user Long name: which of the slaves is being controlled. It is also displayed on any DN9340 units which are being used as slaves.
Page 43
Remote Control Now, the possible destination channels are shown. Use the touchstrip to select one or more channels to copy to. Once all the destination channels are selected, press the soft key labelled “Confirm”. The unit will display an “are you sure” message, and a final press of the “Confirm” soft key will start the copying process.
Operation DN9344: Remote control mode This section describes setting up the DN9344 for remote control operation. Please refer to the DN9340 remote control section (on page 32) for information on controlling the system once it is set up. Press and hold the SETUP button to enter the SETUP menu. Note that the red alphanumeric displays are now showing Last Recalled Memory and Communication (COMMS) mode.
Operation DN9344: Contact Closure (RELAY) mode This section describes setting up the DN9344 for relay operation. This allows memories to be recalled using a simple contact closure mechanism. Press and hold the SETUP button to enter the SETUP menu. Note that the red alphanumeric displays are now showing Last Recalled Memory and Communication (COMMS) mode.
Operation DN9344: Stand alone mode To prevent any changes to the settings in the unit, set the Communications Mode to OFF. Press and hold the SETUP key to enter the SETUP menu. Use the UP and DOWN keys to select OFF for each section of the unit. Press SETUP to confirm (unit will display password menu).
The system developed by the Klark Teknik research and development team for the Helix series is rather different. It draws on KT's unrivalled experience in equalisation, and uses the signal level to directly control parametric equalisers.
Page 54
If we now replace the parametric with a Helix equaliser and select the dynamic EQ, we have some additional controls. Frequency and Q controls are as before, but now we have two pairs of controls replacing the single cut and boost control; these are [low threshold] / [low level], and [high threshold] / [high level]. If we set the frequency and Q controls to the area that we wish to control, then the processor will monitor the signal level in that frequency range.
Page 55
Without changing modes or making any other selections, we can make the unit operate ‘the other way up’ just by selecting suitable values for the two thresholds and levels see Figure 3. igure 3 Helix with boost at high signal level 04/12/02 10:56:55 In this case, [low threshold] is -20dBu, [low level] is 0dB, [high threshold] is -5dBu, and [high level] is +12dB, so that instead of cutting this frequency range as the level increases, we are now boosting it.
Application note 2 :What do we mean by all these Q types? The “Q” of an audio equaliser describes the steepness of the filter - the degree to which it will affect signals either side of its nominal or “centre” frequency. In general, the Q of a peaking filter is defined mathematically centre _ frequency as ,...
Page 57
06/17/02 12:38:05 Proportional Q is the mode of operation familiar to users of the Klark Teknik analogue graphic equalisers such as the DN360. As the amount of cut or boost is increased, the Q also increases. This has the effect of making the equaliser “focus”...
Page 58
Symmetrical Q Klark Teknik Symmetrical Q 06/19/02 10:53:43 This class of equaliser has the same curves in boost as the constant-Q type, but then has cut responses that are symmetrical with the boost ones. In other words, the bandwidth in cut is defined not according to our usual definition of Q (see constant-Q above) but as “the point were the signal is cut by 3dB less than the maximum...
