Professional 750-Watt Stereo Power Amplifier with ATR (Accelerated Transient Response)

The remarkable KM750 packs a heart-stopping 750 Watts of output power into a lightweight (18.7 lbs/8.5 kg) package. 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.

Sublimely Simple Operation
The front panel controls and indicators provide your systems 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 1/4" TRS, plus unbalanced 1/4" 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.
