Hi Paul, I have a question regarding the feedback loop you talked about. It is running at 4 ohms bridged. I have been told that when the amp is bridged that you should leave the channel 2 gain untouched i.

I had used it like this for months and was really disappointed with the result, as I thought a tempest with an ep would be good. So I used the sub minimally and had the gain turned right down so it was barely providing any bass reinforcement. Anyway, one day I was just fiddling with the channel 2 gain and put it in the middle, and then it sounded really good. So I tested it further and noticed the impulse response and the accuracy of the bass was much better.

This basically sounds like what you were talking about with the A, and it seems as if the amplifier was caught in a feedback loop. But you said this usually occurs due to minimal damping when clipping, but the EP was playing no where near the maximum power let alone clipping, so I would have assumed that this was not the case?

So yeah I just thought I would see what you thought of this, and thought you might be interested in hearing about what I have experienced with my amp.

I hooked up an A to a pair of paradigms just for a livingroom listening test of my system. I did not check the mono switch on the back of amp because I had no manual and didn't even think it was in bridged mode s. Naturally I turned up both volume knobs, assuming it was in stereo, but found one channel seemed inappropriately matched in volume.

Fiddling with the volume knobs I was instantly aware sitting between the speakers that the phase of the music was being swung in and out as the right channel 2 was turned up. I thought to myself some jackass has mis-wired the phase, and dismantled the unit. At first I didn't even notice the mono-switch near the outputs bottom its all coloured black. I discovered that someone had indeed subbed the right 2 volume pot, with a non-clicking one, and removed the mini-circuit board as found on the original left, ch 1 pot.

I immediately assumed they wired it backwards, but this didn't make sense, and I then assumed there was some trick or hidden switch to get inputs and outputs both in mono or stereo, and something was out of sync.

I went on the net and discovered the location of the 'mono' switch from the manual I am cheesed I didn't see it before , and discovered it was indeed in mono. So I switched it to stereo. I noticed in horsing around that my left paradigm was popping and sounding crunchy, but it was intermittent and assumed it was just distortion or a bad connection in my mixing console Soundcraft! I never thought to check if my speakers were pumping in and out inaudibly at some subwoofer frequency, and now I wonder if I damaged them by allowing the voicecoils to cook!

Because of this, and your posts here, I have come to the conclusion that Behringer warns not to turn up the right channel volume in mono mode for a really good reason.

Because of this I see no good reason to use the unit in mono-mode, which seems like an ill-thought out kludge that should be avoided. The amp probably works fine with only one music signal in channel 1, and with channel 2 turned completely off.

I don't think driving 1 or 2 cabinets on one side or both will make any difference, but I wouldn't recommend you only hook drivers up to one side in mono mode. Something about output transistors with no load doesn't sound wise. There is a middle phone jack marked for mono use, and I think that if you want to use the amp in mono mode, you had better use this jack, and not the normal outputs, either the posts or the separate outputs.

I suggest you use the mono output jack to ensure that both sides see a proper load, and if you want to hook up more than one speaker cabinet then use a y-chord or hardwire two speaker lines in parallel to a single phone jack. I hope this helps. No warrantees. My amp is now functioning fine in stereo mode, so I have no complaints about the price.

I can pan inputs to both sides, and have effectively mono without any worries caused by risky hookups. In the past, I seem to recall that amps wired mono generally fail catastrophically more often than running channels separately, but that may not apply to the most recent designs. I have not run the Europower for any amount of time in bridged mode, but you should check the manual for how to do it correctly. It's been so long I don't remember. You should also get the same power with each channel driving individual VCs.

I've never seen the Europower unstable, but it doesn't sound like you are talking about the same thing. It appears that you may not have set it up correct. Check the manual! Hi Paul, The thing is I had it set up exactly as Behringer recommends for bridged operation in the supplied manual, and I have checked to make sure I had it set up properly multiple times to see why it sounded so poor.

Then I checked on some forums not sure which one exactly and that confirmed that I had it setup correctly. The thing is no matter where I looked apart from the Behringer manual there was almost no mention of Channel 2 gain, and I was surprised how much of an audible difference in terms of response, not output changing that made.

Yeah I thought I would bridge the amp so I could control the sub output through the one gain control, but it is probably a good idea to try powering through 2 channels to see if there is much difference. The behringer manual says turn the channel 2 gain as far to the left as possible. Paul, Adding relays for the outputs isn't difficult or expensive.

The output oscillations you mention with the OB's make me think that the amp is faulty as it's design is very conventional. Hi Paul Thanks for all the information on your website. I know you don't recommend using the A to drive subs.

However, I fear that the EP and the EP successor might have too much power that will kill my sub. Or can I get the EPs to match in output to the sub? For a single sub it's much easier to get a plate amp. You might consider an O Audio w or w - well designed and good value. The reason for using pro power amps is to get a lot of power for two subs cheaply but you need to add a crossover with some gain in it - a plate amp provides that. For one sub with moderate power demands you can't beat a plate amp.

Also keep in mind that more amp power means headroom which is a good thing. For home theatre, excursion is the limiting factor. For music, that is where you can cook a driver with too much continuous power that eventually causes the coil to overheat.

You avoid that by simply not running it for a long time at a high level. Having a lot more amp power than the driver thermal power rating means you can cook it, but sensible use will prevent that happening. It's like having a high powered car.

A powerful engine doesn't make you drive at kph! All comments are moderated. August 18, Review: Behringer A power amp. Update March : I posted previously that this amp had failed. However, it turns out that it was in fact the IEC power cord that failed, a rare problem and fortunately one that is easily solved. However, I do still hesitate to recommend this amp due to problems with one of the inputs.

Since this is a popular page, I'm leaving it here but I'd suggest people consider Emotiva power amps. Behringer A is one of the best value power amps on the market. I have used this amp in my active system for a number of years and find it's performance to be quite respectable.

For many the looks will be a stumbling block to uncovering a bargain. The attenuators and face plate are plastic and do appear a little cheap. The lights on the front show the output level are a little more bright than many would like. With the lights down low for a movie they are over-bright and can't be dimmed. The case seems sturdy enough and for the price there is nothing to complain about regarding it's quality.

AMPLIFIER A500 POWER AMP 600W

I love finding bargains that perform far better than their price would suggest! People tend to be rather polarized in their love, or dislike, of Behringer. Most of the criticism seems related to Behringer charging much less for similar products than some of their competitors. For better or worse, Behringer has changed an entire industry. Before they came along, companies like Mackie had plenty of customers willing to pay premium prices for their gear. But then Behringer changed the status quo with similar products for a small fraction of the price. Mackie, for example was was forced to move their manufacturing to Asia, update their products, and radically drop their prices to stay in the game. The same has been true of other competitors. Today, not surprisingly, Behringer has a lot more reasonably priced competition. And similar amps by highly regarded companies like QSC, and Crown cost even more.

REVIEW Behringer A800 Class : Photos uniques !

Well received value stereo power amp. Ordered one on Tuesday from Amazon UK and received it today. Drives my 4Ohm speakers with ease. Amazing value.

Behringer A500 Amplifier: Objective Test Results

The Behringer A power amplifier is an incredibly affordable solution for any environment with passive speakers, from studios to commercial outlets such as bars, restaurants and shops. A passive cooling system via two large heatsinks enable the A to remain silent during operation , making this a perfect choice for quiet environments. The amp can run in two modes - 2x W across both channels at 4ohms, or 1x W bridged operation at 8ohms. This makes it compatible with both studio use for users with passive monitors , or commercial environments looking to install a background music or PA system. The option of 4 or 8 ohms make it especially useful for commercial use as it broadens the range of speakers available to use.
