6 Monitoring & Controlling Mixers
There are a variety of IQ mixers (also referred to as “multiplexers” because of their ability to be connected in large
systems while sharing a common bus). One model, the MPX-6, offers only manual control. Another model, the
SMX-6, offers fully automatic as well as manual control. Yet another model, the AMB-5, offers a hybrid approach,
one output channel can operate automatically and one output channel requires manual control. But they all share
one thing in common—they use IQ software for configuration, control and monitoring.
Each model has its own Control Block screen which is selected in the Device menu (
!). Figure 6.1 shows a
single control block from each mixer Control Block screen.

Overall they are very similar. Because the MPX-6 is only manually controlled, it has no ASA control. The SMX-
6 has a Lock control which enables you to “lock” Channel 1 and 2 together. The AMB-5 has no level control on
Input 6, Channel 2 because this input is reserved as an ambient sensing input for automatic level control.
6.1 Initializing a Mixer Control Block
The first step in initializing an amplifier 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 IQ mixer. The Crown Bus loop number must match the physical loop to which the IQ mixer
is wired.
On Line: The phrase “On Line” will appear in the upper right corner of the information area when an IQ mixer
is actively connected to and in communication with the IQ System.
