6.2 Monitoring a Mixer

Two of the mixers, the SMX-6 and AMB-5, have sensors on the their inputs and outputs which allow you to monitor
signal levels. There are a couple of ways to monitor them which will be describe next.

6.2.1 Monitoring from a Display Screen

A quick way to monitor a single IQ mixer is to go to a Display screen by pressing @ from the mixer Control Block
screen. A sample is shown below in Figure 6.2:
The Display screens of SMX-6 and AMB-5 mixers provide dynamic representation of the peak audio level of

each input and output channel as well as the net gain setting of each input. Figure 6.3 shows just one of these input
channels and labels its various parts. The parts are described next.
Address & Loop: The IQ address and Crown Bus loop number of the mixer is shown in the lower left corner
of the Display screen underneath the scale.
Input Signal Level: The center bar graph in each input section represents the preprocessed input audio
level. It is a multicolor bar graph which is green below +1.5 dB, yellow between +1.5 dB and +18 dB and red
above +18 dB. Signals below –40 dB are not visible. The level is preprocessed similar to a prefader or cue level
on a traditional mixing console.
Net Gain: To the left and right of the input level bar graph are the blue Channel 1 and 2 net gain bar graphs.
If the gain is being manually controlled (ASA is off), this bar graph will represent the manual input gain setting. In
this case it can also be increased and decreased from the Display screen using Z to increment and Y to
decrement the level. Mouse users can drag ({) the mouse up or down to change the gain.
