Stereo, mono or bridged, set on the rear.
Passive speakers need an amplifier that fits the night. Some nights call for stereo, others for a mono feed or a bridged load. The rear MODE switch selects MONO, STEREO or BRIDGE operation. The KM750 is a Class-AB stereo power amplifier that takes line-level sources from your mixer.
Connect what you have
The inputs accept balanced XLR, balanced ¼" TRS or unbalanced ¼" TS connectors. The KM750 also has RCA inputs for unbalanced line-level signals. Speakers connect through twist-locking speaker outputs, or bare wire on the binding posts.
Lights that tell you what is happening
SIG LEDs show a signal at each input. A CLIP LED that lights continuously tells you to turn down. The PROTECTION LED lights in thermal protection mode, and the LIMITER switch activates the internal limiter. A GROUND LIFT switch can remove hum caused by ground loops.
Ready for a bi-amped system
With a separate crossover, one KM amplifier can drive the highs while another drives the lows. In the rack it requires two rack units. It weighs 8.5 kg.
