Behringer KM400 Stereo Power Amplifier
The KM400 supplies stereo or bridged amplification for passive speakers in live, studio and installed systems. It delivers 190 W per channel into 4 ohms, with a bridged configuration providing 400 W into 8 ohms.
ATR technology supports transient reproduction, while zero-attack limiters help control overload. Front-panel signal and clip indicators make operating levels easy to check. Professional audio connections, a switch-mode supply and a steel rackmount enclosure complete the practical design.
