So I have a dual Omega 90 set up and love it, except for one thing. When I select "yelp," both amps put out exactly the same tone, synced, so it sounds like a normal monotone siren. What I would really like is for one amp to do wail, and one to do yelp. I would still want the second amp to yelp when the siren is in sweep mode, so turning one amp to only do wail wouldn't work. Does anyone know which combo on the dip switches is needed if this is possible? Thanks in advance.

Ok, let me get this straight. You want amp 2 to do only yelp and amp 1 to do wail as primary then activate sweep of the other sounds when necessary. Is this correct? If so, on amp 2, set the dip switches like this:
group 1- switch 3 on
group 2- switches 2 and 5 on
all others off.
This should get you only yelp coming out of amp 2 at all times
Amp 1 should be set like this:
group 2- switch 8 on (this sets primary tone on amp 1 to wail.
group 1- follow install instructions to determine which sweep sounds you want via group 1, switches 2-8
sweep tones are as follows:
switch 2- wail
switch 3- yelp
switch 4- hi-lo
switch 5- hetero
switch 6- airhorn
switch 7- alarm
switch 8- futura (piercer)
The way I am reading the install sheet, this "should" get you where you want to be as far as one amp doing only yelp constant and the other doing wail with sweep being activated having tones of your choice. I may be mistaken as it's always best for me to have an amp hooked up so I can play with it to figure these things out in real time. Hope this helps or someone more knowledgeable than me comes along to tell you exactly what you need to do.
I am sure you already have this but here is the install sheet anyway. http://fedsig.com/docs/22-U90-00.pdf

Almost, While on wail, I would like to keep both amps on wail, but when on yelp, have one do wail, one do yelp. Then in sweep, have one do sweep tones, and one do yelp. Not sure that this is possible......

I guess it would depend on what kind of control head you have and how it is set up. It doesn't sound possible to me from the knowledge that I have aobut the O-90s. If you can catch Cajunblitz on here some time, He should be able to help you but I think his grocery/bbq joint has taken precedence since he quit installing full time so I don't see him on here much anymore.towlercd said:

I don't think that is possible using the Omega 90 amps because you cannot hold the amps in dual-mode in the Wail and Yelp modes for more than 5 seconds when using the 5000 or 8000 series controllers. As for one amp sweeping through the tones and the other amp held on yelp, you maybe able to do that by experimenting with the dip switches on amp #2. Unitrol recommends that amp #1 be set for maximum tones and amp #2 be set for wail and yelp tones only when using the dual-mode feature.

I think it requires certain wiring of the amps by modifying the wiring to achieve that effect instead of using the dual amp cable.

Ok, so if that's the case, I guess more than I want to get into. Was hoping it was just a dip switch setting that I was missing. Thanks all.
