If your board operators aren’t paying attention to their levels, here’s an alarm you can rig up with lights, a text message or something flashier. If your board operators ARE paying attention to their levels, let us know, because we’ve never heard of any who actually do this.
AE-C2 software 3.23 and later
You define the meter, the threshold level, and the length of time before the alarm kicks in using a Command Library script. That will toggle a bus on and off. You can then use Command Builder to check the status of that device and bus to turn on a light, write text to the surface, or even send a message to a Beta Brite sign.

Copy and paste this string into Command Library and label it “Init alarm”. Add it into the active commands in your audio engine. Once this config is uploaded, it will be active. Copy and paste it carefully – miss a number and the engine won’t start properly.
If you've never dealt with the Command Library before, call us in Support (713) 664-4470 and we can help.
(If you choose to not copy and paste, understand that there are no letter o's in the string, they are zeroes.)
This alarm will turn on device 4 bus 33 if the program meter is below -10 for 3 econds or more and turn off bus33 after audio exceeds -10. It will turn on device 4 bus 34 is over +5 for two seconds or more and turn off bus 34 after audio is brought below the threshold.
The device number is selected by the meter you are monitoring. Port 1 PGM is device04, Port 1 monitor is device05. Port 2 program is device06, port 2 monitor is device07. Port 3 program is device08, port 3 monitor is device09.
Now, here's the string to put in Command Library:
00 02 B2 00 00 02 00 06 00 AE 00 04 00 22 00 05 00 00 00 02 00 06 00 AE 00 04 00 21 00 F6 00 00 00 03
00 02 b2 00 = when device 2 bus 0 turns on (since this is a GPI bus, the only time that this bus can turn on is when all the GPI’s are cleared at startup, so this will force the command to run only at startup.)
00 02 = do two commands
00 06 = the commands are six bytes long
00 ae = an AE command is used to set an effects level in the engine protocol
00 04 = the channel number of the program meter on port 1 (port 2 would be 00 06, port 3 00 08)
00 22 = the effect type, in this case the set high level alarm This is followed by three bytes. Byte 1 = threshold, bytes 2%3 = delay.
00 05 = threshold = +5
00 00 00 02 = delay time = 2 secs
(second command begins here)
00 ae = this is an AE command (see above)
00 04 = the channel number of the program meter on port 1 (see above)
00 21 = the effect type, in this case the too low alarm. The next three bytes are similar to the too high alarm.
00 f6 = threshold is -10
00 00 00 03 = delay is 3 seconds.
Write a trigger in Command Builder that checks the status of the alarm and provides and alert.
Here's some examples using the Beta Brite sign. You could choose to write text to the surface or trigger a GPI that turns on a strobe light. It's all up to you.
