I was thinking of coming from both of the Behringer V-Amp's XLR outputs and then running to each channel of the Peavey. Then I would have separate volume controls for each cabinet. I am running the Behringer in L3.

Do not feed your power amp, combo or head using the V-AMP's XLR outs, but instead use the 1/4" unbalanced outs. L3 is the best mode for this IMHO.

To resolve the volume disparity issue as described, run one 1/4" output to channel "A" of the IPR-3000, and the other 1/4" output to channel "B". Connect one cabinet to the IPR's speaker out "A" and the other cabinet to speaker out "B". Run the IPR-3000 in stereo mode and use the attenuators to even-out the volume disparity.

Cheers!

CharlieC thank you once again. I appreciate the tip yet again on the V-Amp. I thought that seemed like the right thing to do from my years as a pro audio engineer, but I wanted to make sure my thinking was not flawed. Thank you yet again, may I ask why you would use the unbalanced 1/4" outputs vs. the balanced outs. No argument here just curious. Obviously looking for the best sound so your input and hints are greatly appreciated.

Under L3 mode, the V-AMP's XLRs output a signal imparted with Behringer's ULTRA-G cabinet sim and are best used to feed a mixer/recorder and not an amp driving an actual bass speaker/cab. Additionally, the XLRs are fixed-volume and are not governed by the V-AMP's MASTER knob. Under L3 mode, the 1/4" outs do not feature the ULTRA-G cabinet sim and are better-suited for an amp driving an actual bass speaker/cab. The 1/4" outs are governed by the V-AMP's MASTER knob.

With such short cable runs from V-AMP to amp/combo/head the quality difference between balanced XLR and unbalanced 1/4" connections is negligible.

Cheers!

Well had to send my BVAMP Pro back to the mother ship. Thank goodness for warranties. The weird octave issue just wouldn't go away so off she goes. Anyone have any experience with Guitar Center /Behringer warranty coverage? Hoping to have it back sometime this year

I've been watching this thread for ages and finally scored a desk top model on Ebay for very little money. (I haven't received it yet

)

Only problem is that it has no foot pedal with it (FS112V/FS112v-2), I know it is not essential to it's operation but would be nice. To buy a new one costs more than I paid for the V-amp.

Does anyone know how the FS112v footswich is wired internally, or can anyone post gut shots please.

I know they have a fitted cable terminating in a stereo jack (TSR) and a couple of PC board mounted momentary action push switches and not much else, so are pretty simple.

Thanks.

I never used mine with the V-amp, I just use it to mute my Fender racktuner on gigs

It's just a rugged footswitch with 2 momentary switches, I dont think it has any circuitry inside

With this said, regarding the TRS jack, I will guess that shorting "Tip to Sleeve" is the circuit for one button and "Ring to Sleeve" may be the other.

Cheers!

Thanks Charlie, yes that was my thinking but I just wanted to make sure before I started shorting things out and letting any magic smoke out.

The other method I have seen used is switching different value resistors, but thinking about it you would only need a TS jack for that.

Just got a reply back on another forum as to how the foot pedal is wired, copied here for anyone else that might need it. (Thanks go to FiveseveN from freestompboxes.org)

Momentary microswitches indeed, with parallel debouncing caps IIRC. The DOWN button shorts tip to sleeve, the UP shorts ring to sleeve."

Now all I need is the V-amp to be delivered.

Ah yes, let us not forget the parallel debouncing caps!

Cheers!

The guy is from Romania so I suspect that English is not his first language, but I had to smile when I first read it.

That actually does make sense. Contacts do bounce and the caps smooth the multiple transients into one.

Agreed!

My comment was on the way it was so casually geek-inserted in the reply, after we geeks omitted that detail in our discussion here :-)

dincz · #**694** 11-29-2012, 01:44 PM

and I was just pointing out that his English was actually perfectly good - more in response to delta7fred.

But I can see how it could look a bit like "tappet flange giblet oscillator"

Charlie
freestomboxes.org is a builders forum so geek-speak is the norm and I was in cut and paste mode from one forum to another. It never even occurred to me that all bass players are not electronics geeks.

dincz
In no way was I criticising his English, it is just that I have never seen it written like that before and it made me smile.

Brits are probably the worlds worst when it comes to learning other languages as we just expect the rest of the world to know ours.

I've had a couple of days to mess around with the V-amp (non Pro) and must say I am very impressed.

A big thanks to Charlie for putting together the guide and tips, without which it would have been way harder to get my head round this beast.

No thanks necessary!

A few weeks back I had a rehersal at a studio with a TraceElliot ~300w head+marshall cab that just sounded fartastic no matter how much I dialed it and tweaked it, the lighter string were barely heardable, the heavier strings would make a a huge boom and muffle any other instrument, in short it was a total mess.
Next week I took my BBVA plugged it in the return fx loop, the whole band was amazed it sounded so good while playing in the exact same amp.

Got to try it live again this weekend, BBVA L-out in the return fx loop of a Warwick ProFet 5.1 (which I love the sound btw) driving a 4x10 + 1x15 stack, R-out to the FOH mixer
I didnt need a single tweak apart from the volume level on the amp, the soundguy loved it as well, got my sound check done in 20 seconds, everything sounded awesome.
