I'm planning to run from a Peavy sub to my F1 812 mains. My sub only has a single input (so I guess I just run one cable from the left output on the mixer to the single input?). There are 2 outputs on the sub going to the 812s so no issues there. Is this the correct setup? I know the F1 Sub has two inputs - I'd be more comfortable with that. Is it unusual for a sub to only have 1 input? Any better way to connect everything?
Hi, Critter.
Thank you for joining the Bose Portable PA Community. Welcome.

There might be a better way to do this.
Please tell us about your signal chain from beginning-to-end and give us a link to the manual for your mixer.
Thanks,

Thanks for the quick response! Since there's only one input in the Peavey sub I connect as follows: I go from the left channel of the mains of the Behringer XR18 mixer (right channel just open - nothing plugged into it) into the single input of the Peavey sub. There are two outputs in the sub so I go from one output to one of the F1 812s and from the other sub output to the other F1 812. We have 4, sometimes 5, separate monitor mixes coming from the aux outs of the mixer to powered monitors. That's about it.
I've attached the manual. Your advice is much appreciated!
By the way, we don't run any of the inputs into the mixer in stereo - everything is a single input. Basic stuff - a vocals, guitar, fiddle, mandolin, dobro, etc. Only thing in stereo are channels 17/18 for "break music" through ipad/iphone.

Okay - so live music.

And mono.
Good - those were key things to know.
You can leave the F1 Model 812 systems connected directly to the mixer main outputs. Then set up a separate aux output for the subwoofer and only send the channels with low-frequency content to it. There's no need to send vocals, fiddle, mandolin, dobro to a subwoofer. There's not much musical content in the subwoofer range for those inputs, just excessive low-end reverberation and mechanical rumble. You might only need the subwoofer for the break music
There is lots of information online about
Aux Fed Subs with the Behringer XR18

Thanks! That made complete sense. Just tried it out on a Memorial Day gig and it worked great! I put the break music through that aux as well. I plan to buy an F1 Sub but haven’t pulled the trigger yet. That will make things even easier. I’m a big fan of Bose equipment - both professional and personal. I appreciate the advice!
Hi, Critter.
Thanks for coming back to tell us you got things working.
Please tell us about your music.
Thanks,
ST
Just to make sure I did this right yesterday: the bass will only go out through the aux out which is signaled to the sub? I did not have the bass going through the mains at all (to protect the mains). That's what I figured you meant but I saw this in one of the links you sent: "Connect the sub to an AUX output, and only run like, bass and kick drum to the sub. You'll also run those through your mains, of course. But you'll get some more low-end from the kick drum (because it's run through the sub) and the bass guitar (because it's also in the sub)"
Should I run the bass through the mains as well as mentioned above?

I would run everything including kick drum and bass through the mains. There are frequencies from both above the range of the subwoofer.
Add kick drum and bass to the aux out for the extra low-end support.
All good?

Thanks - all good. I was always under the impression the low frequencies of the bass were detrimental to the mains. Thanks for the enlightenment!

You can set the F1 Model 812 EQ switches to WITH SUB.

Critter Taylor Band - we're a Houston, Texas-based, 4/5 piece band - guitar, fiddle, mandolin & bass. We play originals, which we call "Texgrass", as well as cover some Texas Country and Americana. We throw in a little fiddled up Classic Rock for good measure.

Great to get to know you better.
