Assigning Digital Microphone Array Channels To Physical Inputs
When HDX digital microphone arrays are used within SoundStructure Studio,
SoundStructure Studio assigns the processing for each digital microphone
input from a physical analog input. SoundStructure Studio will reserve
processing by starting with the last analog input channel and working towards
the first analog input.
For example, if a single HDX digital microphone array is used with a
SoundStructure C12, the processing from physical analog inputs 12, 11, and 10
will be used for the digital microphone elements A, B, and C respectively and
the physical inputs 12, 11, and 10 will not be able to be used for any analog
inputs. If two digital microphones are used with a C12, the second digital
microphone’s elements A, B, and C will utilize the processing associated with
analog physical inputs 9, 8, and 7 respectively. In this example, analog input
signals may not be connected to inputs 7-12.
When analog inputs are also used as part of the design, such as for a wireless
microphone and program audio in this example, the analog inputs that are
used will be allocated from the first analog input to the last available input.
This allocation and assignment of analog inputs can be viewed from the wiring
page as shown in the following figure. Note that the particular microphone
element associated with the labelling A, B, and C is highlighted in green on the
wiring page for each digital microphone input.
Using HDX digital microphone array inputs requires the same processing paths that
are used with analog input signals. When HDX digital microphones are used, any
analog signals on the physical inputs assigned to the HDX microphone elements
will not be used.
