KM750The remarkable KM750 packs a heart-stopping 750 Watts of output power into a lightweight (18.7 lbs/8.5 kg) package, thanks to our Accelerated Transient Response (ATR) technology. Ample power (750 Watts in Bridge mode; 2 x 400 Watts @ 4 Ohms; 2 x 200 Watts @ 8 Ohms) and high-tech efficiency combine, giving you a supercharged workhorse that will keep your rig kicking for years and years to come. |
Accelerated Transient Response Delivers the Knockout PunchIt takes huge pulses of energy (current and voltage) to propel a woofer cone out fast enough to match a bass beat. That’s called Transient Response and it’s the holy grail of amp design. By carefully selecting transistors with extremely high slew rates and optimizing other proprietary parts of our circuitry, our amps are able to react instantly to even the most demanding electronic bass impulses. If the woofers in your PA system can keep up, your audience will hear a tighter, crisper, more natural sound. Instead of operating relatively continuously like most power amps, the KM750 features rail tracking for effectively modulating the power supply rails with only the peaks of the input signal. This technology has revolutionized pro audio amp designs with its outstanding performance and efficiency. |
Sublimely Simple OperationThe front panel controls and indicators provide your system’s vital signs at a glance. After pressing the Power button, the Power LED lights to show the amp is ready for action. All channels feature positive-detent Gain controls with Signal LEDs that light when a signal is present, as well as Clip LEDs that alert to reduce the input signal. Just as elegant as the front, the rear panel is home to balanced XLR and ¼ " TRS, plus unbalanced ¼ " TS and RCA connections. Take your pick of professional locking speaker Outputs or touch-proof binding posts to securely connect speakers. The same panel contains the switches that put the KM750 in Mono, Stereo (two channel mode) or mono Bridge mode. Flick the Limiter On/Off switch to activate the built-in overload protection. |
Sound ValueThe remarkable KM750 power amp was built for the working musician. It is exceptionally light, packs a massive 750 Watts of output power, thanks to our Accelerated Transient Response (ATR) technology and is built rugged enough for life on the road. Check out the KM750 at your Behringer dealer, or order yours online today! |

Original: Bought this from the warehouse at an incredible savings. Using to power my DIY home theater subwoofer with a Dayton Rss315HO-12 4 ohm driver. When running in 'stereo' mode, the sub sounded anemic, no authority like it did with the 500 watt plate amp this KM750 replaced. I wasn't thrilled, but it wasn't so bad I would return it.
Then, after having a few adult beverages one night, I made the executive decision to try bridging the amp and see what happens. Let me say, the sub came alive. I mean to the point of when it was 'stereo', and gain almost 100%, still sounded anemic. But with being in bridged mode, the gain is not even 1/2 way and the sub is ALIVE! [insert menacing laughter]. This is a GREAT amp for consumer use. Missing having a trigger control, which can be problematic, I got one of these that was recommended to me in a forum: https://smile.amazon.com/gp/product/B00WV7GMA2/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
Now, the actual review since you now know how it is being used.
The weight is good. The build/finish is 1st rate. No banana plugs can be used, but pins will work. I just used bare wire, 12 gauge. The power light is an extremely annoying and extremely bright white LED. A piece of electrical tape covering it cured that nuisance. The fan...what can I say. It isn't horrific sounding, but it IS annoying AF watching a movie and having it in the same room. Cool air is drawn in thru the top and warm air is exhausted out the left side. Used in a noisy commercial environment, the noise won't be noticed, but in your living room...
What I did was to just plain disconnect the fan. I measured for several days the internal temperatures before, during, and after heavy home theater usage and have determined the very small gain in heat will be easily tolerated by the electronics for years to come,
I recommend this amp. Dollar for dollar, pound for pound, watt for watt, you will find no better.
This is my first Behringer product and I am very impressed.
The fan runs constantly and it is not a quiet fan. If you're doing music in a club it's probably fine, but I'm using this for special effects in a quiet room, and the fan is plainly audible 40' away. I disconnected the fan, because for my purposes I don't need it. Remove 12 screws and unplug the obvious connector from the board, and done.
The manual is big on pictures of attractive young people, but has no specs other than wattage, which is not specified as RMS, so think of it as at best a 100W amp into 8 ohms. It seems silent at no signal (there's a very faint mechanical buzz) and I'd wildly guess a S/N of maybe 90db. It has a ground lift switch, which for once I did not have to use.
People talk about black backgrounds in audio. This doesn't have one; it is not audiophile gear. I think the guy comparing it to a Bryston 4B is just plain wrong. But it's hard to complain at this price point.
It puts out a reasonable amount of power, though like most amps in this price range, the stated wattage is peak and probably overstated. I am using it to drive 8 ohm speakers and have it turned most of the way up. Nothing is clipping and the unit remains cool.
Controls are simple - 4 switches in back that are set and forget, a power switch, and two volume knobs in front. They have detents and feel reasonably precise.
I paid around $200 and consider that fair, but the amp needs a quiet fan and a 12v trigger to get 5 stars.
