Phoenix Audio MT454-DTI-PA User Manual

 

 

 
For optimal performance we recommend the following steps 
while setting up the Octopus system: 

1)  Making all the necessary connections, including the 

microphones, speakers, communication interface(s) 
and controls. 

2)  Using our setup wizard to configure the unit(s), set, 

tune, and test the microphones and speakers’ 
connections 

3)  Using our audio setup utility for further settings 

 
The following chapters will walk you through these three 
steps. 
 

 
Microphones / Inputs 

If your setup includes up to four inputs (including Matrix 
microphones as well as SR and Aux inputs) you should 
configure the unit as a “Stand Alone” unit (configuration is 

done with the setup wizard and is explained in details in the 
next chapter). Connect your inputs to the Mic inputs in the 
back panel using standard XLR connections (see diagram 
below).  
 
If your setup includes more than four inputs you need to use 
several units (depending on the number of inputs) and 
connect them in our unique “Layered Star” expansion 
configuration. In this configuration the Matrix microphones 
(unlike SR or Aux input) are connected to lower hierarchy 
level units which will be configured as Slaves - up to four 
microphones per Slave (so if you have 5-8 Matrix inputs you 
need 2 ‘lower level’ Slaves, 9-12 inputs you need 3 ‘lower 
level’ Slaves, and so on). 
 
Up to four Slaves are connected to either a mid-level Slave 
or a Master unit using a standard XLR to XLR cable (not 
supplied) - the Link Up of the lower level unit is connected to 
one of the microphone inputs of the higher level unit. Note 
that with two layers (one Master and up to four Slaves) you 
can connect up to 16 Matrix microphones (see diagram 
below).
