9 Monitoring & Controlling Matrixers
There are a variety of IQ matrixers. One model, the MRX-24, offers 24 pairs of low-current relay contacts which
can be used to switch microphone, audio line-level, digital and DC control signals. Another model, the MRX-12,
offers 12 single high-current relay contacts which can be used to switch loudspeaker lines, motors, lighting and
power supplies. Both of these models also have slave versions (MRX-24S and MRX-12S) which add to the
number of relays, thereby expanding the possible size of a matrix.
All matrixer models share a common Control Block screen as shown in Figure 9.1 below:

9.1 Initializing a Matrixer Control Block
The first step in initializing a matrixer control block is to set the IQ address and Crown Bus loop number. This is
normally done automatically during a roll call. However, you can set them manually if you need to configure a
system off-line.
IQ Address & Crown Bus Loop: The IQ address number you enter must match the physical IQ address
switch setting on the matrixer. The Crown Bus loop number must match the physical loop to which the matrixer is
wired. Note: Slave matrixers will have two numbers listed in the IQ address space. The first number is the IQ
address of the master unit followed by “:S” and the slave address number. Each slave matrixer must have a
unique number.
On Line: The phrase “On Line” will appear in the upper right corner of the information area when a matrixer
is actively connected to and in communication with the IQ System.
