USER GUIDE
The Home Page
The Home Page presents an overview of the configuration of the device. It indicates the user-define Device Name at the top, and
shows the four Drive Modules. In each Drive Module the top line shows the Input DSP channel ('A', 'B' etc), and the name the
user has given to this channel. The bottom line shows the physical input number, and a list of the outputs which are routed from
the Drive Module.

Drive Modules
The iK42/iK81 Series uses Drive Modules to represent loudspeaker sub-systems. Drive modules result in a less processor-centric
and more speaker-orientated system design. A drive module is defined as the processing provided by one Input DSP, and a
number of outputs, which are associated with one-another by means of routing. For example, if Input DSP B is routed to outputs
3 and 4, then this is a 2-way Drive Module; input DSP B forming the 'master' control, and output DSP 3 and 4 providing the driver-
related control. The Input DSP parameters then control the Drive Module (and thus the speaker sub-system). The Drive Module
control panel in the Vu-Net application is then used for control and monitoring of this sub-system.
Drive Module Presets
Presets do not change the settings device-wide. Rather, recalling a Module Preset creates a Drive Module by 'consuming' a
number of consecutive outputs and setting up routing between the Input the preset was recalled on and those outputs. The
parameters in that Drive Module are then set according to the parameters in the components in the Module Preset.
Note however, that modules with non-consecutive outputs can be created by manually manipulating the routing, and then
recalling Component Presets to the individual outputs. The resulting system can then be stored in a Snapshot. Such a Module
cannot be saved in a Module Preset.
Note: When a Module Preset Recall consumes outputs to construct a module, it treats a pair of Bridged outputs as a single
channel, so recalling a 2-way Module Preset will consume 3 output channels if a Bridged pair is encountered. See Bridge Mode
Note: DSP inputs are not the same as physical inputs. The iK42/iK81 Series has four audio inputs and four DSP inputs. This is a
matrix mixing system where any physical inputs, be they analogue, AES3 or networked audio feeds, can drive any number of
DSP inputs.
Component Presets
A Component Preset represents the processing for just one output. Any part of a Module Preset may be recalled to any one
output. A Drive Module comprised of parameters which have been recalled to its outputs using Component Preset Recalls can
then be saved into another Module Preset provided the outputs remain consecutive (i.e. you have not changed the routing
manually). If the routing has been changed manually, then the whole arrangement may be saved into a Snapshot. See also
Snapshots and Recalling Components.
Factory Module Presets
The device will contain a library of Factory Presets designed to suit a range of enclosures.
Factory Presets may contain some parameters that are fixed and hidden from view; the remainder of the parameters are
available for user manipulation. The number and type of hidden parameters is dependent on the Factory Preset, typically
