I played an acoustic gig this last weekend and it was a little more packed than usual. it was at the VFW, holds around 100 people or so in the canteen area. Usually, i'll have my acoustic amp, Behringer Ultracoustic ACX450, and crank it to around 7 or 8 on both channels and it works just fine. For some reason i had trouble hearing myself this time. A buddy of mine has a Kustom 100w powered monitor he said i could borrow if i wanted, it has a line input. If i mic the amp and run it thru the monitor, would this help any or would i need to use the mixer as well. I don't want to take a big setup if i don't need too for this gig. If I have too then i guess i will. Any thoughts on this? I had the amp on an amp stand leaned back. the issue wasn't the sound in the room, just hearing myself.

thanks,
Dave

Pretty sure you "can" plug a mic directly into a powered speaker, but you may deal with some nasty feedback issues since you have no way of adjusting the mic gain other than to turn the speaker up or down. Using the speaker as a monitor instead of a main will probably compound the problem.

Interesting question though. I've never tried it so I'm curious how it works out.

Borrow the monitor and try it at home.

I found at least two models of Kustom 100 Watt powered monitors that have volume (level) controls.

There are three approaches...

Set the ACX450 on one side of you and the monitor on the other side, both facing the audience. The signal from the amp into the monitor should not reach the mic on the amp...that is one feedback source. By placing both on the floor facing directly towards the audience, AND if you "spread them about 3 feet away from where you stand with your vocal mic...and do NOT tilt the speakers towards the vocal mic, you would probably not pick up enough signal in the vocal mic to initiate feedback.

Option 2.
Set the Behringer to one side and the monitor in front facing you. There is a stronger risk of creating a feedback loop if the sound from the monitor reaches the mic sending signal to the monitor from the ACX450. Angle the monitor slightly away from the ACX450.

Option 3.
Set your ACX450 on a chair, closer to your own ears but still facing your audience. The down side is you will lose a slight amount of low frequencies because you no longer "couple" with the floor...not the end of the world...you can experiment with all three options. With the "amp on a chair" option, consider leaving it on the floor but angling it towards your ears.

We are a three piece, acoustic electric guitar, electric bass, cajon, two vocals. ONE mixer and ONE Yamaha DBR10 powered PA cabinet. We set the powered mixer on the floor parallel to our shoulders, facing the audience, between the two vocalist. (Outdoors, we usually add a second DBR10.) We have never had feedback.

WE PLAY SMALLER GIGS THAN YOU. 50-75 maximum audience thus far. It is not lack of equipment, we are just trying to keep our foot print small. We can fit into almost any living room...and still have room for "audience". There are work arounds and other alternative set ups that would work for you...borrow the monitor and if you need another mic, get that too....EXPERIMENT.

You could drive the monitor with the line out or send of the desired channel of your Behringer, but you'd only get your vocal or your guitar out of the Kustom, depending on the channel you lined out.

I've done this a lot with my 450.

I don't think that Behringer amp has a line out Steve. Not that I could see anyway.
