The assignable inputs and outputs connect mixer elements across mixer columns, to the external 
inputs and outputs of the SSL Soundscape hardware, or to the host PC via the “streams”. In our 
diagrams they are not numbered. Instead they are indicated by an “A”, and this means that their 
routing can be determined freely using the I/O and DSP Assign tool. The individual input(s) of 
input elements and individual output(s) of output or send element(s) are assignable in this way. 
The example below shows an 8 in/8 out output element. Initially, the element’s outputs are 
assigned to analogue outputs 1-8. The I/O and DSP Assign tool is then used to change the 
element’s output assignment to analogue outputs 9-16:
