1. Dip Switches
Dip switches set the Matrix system address. 
If the system is to be expanded, each Q 
Matrix unit must be defined as Master, Slave 
1, 2 or 3.
If you are expanding the system, only line 
inputs 1-8, MIC1 and 2 x Remote Paging 
Consoles of the Master Matrix are enabled. 
All Slave Matrix units connected to the Master 
will use the Master Matrix inputs. 
For the avoidance of doubt, if a Matrix unit is 
configured as a slave, the slave Matrix Inputs 
1 – 8, MIC1 and remote paging consoles 
inputs will be disabled. However, the optional 
wall plates (QTVCS and QT1WML) can be 
used to operate these additional zones.
Dip switch settings are as follows for 
configuring the Q Matrix 88 as a Master or 
Slave:
