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: DSP inputs are not the same as physical inputs. The HDC48 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
