Power amp bridging help

#3
Looking at the photo of the back of the amp on their web site, to bridge, you'd need to do the following:

1. Use input number 1

2. Set up the Filter and Limiter switches for Channel 1 (Limiter ON, Filter ON, you choose the frequency...if you can't hear the difference, go with 50 Hz).

3. Set switches 6 and 7 for the Bridge Mode.

4. Switch the Limiter and Filter for Channel 2 off.

5. The loudspeaker can either connect to the upper Speakon (if your cable is wired 1+ and 2+ (read the little chart next to Output 1)) or the Red binding posts as shown in the graphic to the right of those.

NOTE: Most commercially available Speakon cables are wired 1+ and 1- for conventional operation. As long as it's a 4 conductor Speakon plug (they also make 2 conductor plugs with the same size/shape body) you can easily rewire it.

6. You adjust the input gain with Channel 1's control with Channel 2 turned all the way down. Pay close attention to the instructions printed on the back of the amp near Channel 1's XLR input (and in the manual of course).

It's really not that hard as long as you don't let all the weird little switches and stuff freak you out. Just follow the markings on the amp in order (perhaps write down the list checking them off as you go) and you'll be done before you know it.

Easy enough?

Good luck!!!

Thanks guys. I just talked to my buddy tht works at guitar center and they've got a used peavey pv1500 for $250 that I'm sure I could work down to $150-$200 that I'll go with instead. also he said the can give me a banana (binding post) to 1/4'' adapter to make it work.

Behringer seams ok for the dollars but peavey has never let me down, I'm gonna go with the peavey.

Peavey are always good :) One thing i have to say tho, ive looked everywhere on the net, and i havent read a single bad review on these behringers units! (other than the knobs feel cheap aparently)

From what I've read the peavey has a very un-colored sound. Also, GC doesn't carry behringer power amps and I have a $300 credit there so the peavey it is. Now I just have to decide for between the RBI or the BMAX for my clean channel. Once I get my other full stack running I'm going to be using the Rick-o-sound to run my bridge pickup with quite a bit of overdrive and my neck pickup with some clean low bass and run it both channels

One word on the Peavey-
I believe it only bridges to 8 ohms.

Now, I could never get confirmation on this, but I fought with mine a LOT (I had a Demeter VTBP-201s running into it) concerning the amp going into Clipping mode.
Granted it has whatever they call it, a signal limiter that is defeatable on the back, but I didn't want to cut that off for fear of blowing the cab I was using at the time!! (Schro 410R).

I only had one preamp to try with the amp, but I never got my Demeter past maybe 10:00 on Volume without the amp freaking out big time.

Plus, I could never get the middle Speakon to work right... :hmm:

I'm sure it'd be a good amp for PA use, and I know you can get them cheap, but honestly I'd go for a Mackie 1400i or something instead. The Peavey just had too many "ticks" for me at least, to be a really good, no-worries bass amp (like my QSC or old Stewart World).

"WARNING…Regardless of what connections are used, the minimum parallel speaker load should
always be limited to 2 Ohms per channel or 4 Ohms BRIDGE mode for any application. Operation at
loads of 4 Ohms per channel, or 8 Ohms BRIDGE mode, is more desirable for sustained operation
applications because the amplifier will run much cooler at this loading. Operation above 4 Ohms per
channel and even open-circuit conditions can always be considered safe, but sustained operation at
loads below 2 Ohms could result in temporary amplifier shut down due to the thermal limit circuitry."

So, we'll see I guess. If it doesn't work out, I've got 30 days to return it.
