Review Summary
2019-01-21T14:36:15
The Behringer KM750 is a fantastic piece of kit for the beginning hobbyist as well as the PA professional and everyone in between. It is very easy to use and there is more than enough power to push the drivers I need it to. The only reservation I have comes with the cable that accompanied the amplifier. I am not very familiar with PA wiring, so I am unsure how many conductors the cable has. I think it is a 4 pole connector, but i’m not certain. I would have liked to see that specified somewhere. Other than that, I am extremely satisfied with my purchase.

Designed for small venues, portable PA systems, and places of worship, the Behringer KM750 is a stereo power amplifier capable of delivering 400 watts per channel at 4 ohms, and up to 750 watts at 8 ohms in mono bridge mode. It combines strong performance with great value, featuring built-in protection systems and Accelerated Transient Response (ATR) technology for improved clarity and punch. Each channel includes switchable limiters to guard against sudden peaks, protecting both your equipment and listeners. Its toroidal power supply ensures stable, clean output, while connectivity options include balanced XLR, unbalanced 1/4" TRS and RCA inputs, along with speakON and binding post outputs. Housed in a durable steel chassis, this 2RU unit is designed for easy rack mounting.
Accelerated Transient Response (ATR)
ATR technology enables the amplifier to respond quickly to fast, powerful bass signals. By using high slew-rate transistors and optimized circuitry, it delivers immediate energy bursts needed to drive woofer cones efficiently. This results in tighter, more defined, and natural-sounding bass reproduction.
User-Friendly Design
The KM750 features a straightforward front panel that provides all essential information at a glance. A Power LED indicates when the unit is active, while each channel includes independent Gain controls. Signal LEDs show incoming audio, and Clip LEDs alert you when levels need adjustment.
Enhanced Control Options
The rear panel offers additional features to optimize performance. Its Clip Limiter automatically detects distortion and instantly reduces the input level to maintain clean sound output, ensuring reliable operation during demanding use.
Efficient Rail Tracking System
Instead of continuously running at full power like conventional amplifiers, the KM750 uses rail tracking technology to adjust power supply levels according to signal peaks. This improves efficiency and overall performance, making it a modern solution for professional audio applications.
