At first glance, the SP46K may look like an expensive piece of kit. But when you consider that this amp is capable of doing the work of several amplifiers the picture begins to become a little clearer. When you then look at the weight and size advantages, well, the benefits of this product become all too apparent.

Running a complete PA system or monitor rig from a single 2U amp weighing less than 9kgs is certainly a boon.

Two of these amps could possibly run your PA system and your monitor system and be housed in a rack case weighing less than 25kgs.

The fact that the amp channels are bridgable adds great flexibility to the mix. As well as being a powerful 4 channel amp, the SP46K can also be a stereo monster (2 x 2000 watts @ 4ohms), great for sound hire companies whose assignments are often very different and varied.  

Class H topology maximises efficiency and component life, a full set of protection features are present, and a damping factor of >500 means they are great for driving subs.

The SPS46K can drive loudspeaker loads down to 2 ohms nominal impedance.
