I bought this to use as a poweramp for my bass rig. I use a Sansamp RBI preamp into the XLS 1002 which when bridged gives 1100W into 4 ohms (more than I'll ever need).
The selecatble dual sensitivity input is a superb inclusion and improvement over predecessors. It allows lower power input sources and preamps to be connected etc.
The overall sound is clean, transparent, powerful and replicates the output of my bass and preamp without colouration.
The built-in crossover is brilliant and very easy for a technophobe like me to program the output frequency range. Choose from high pass, low pass, or select a bandwidth.
The unit is well built, looks superb in my rack unit (the blue LEDs match my Korg rack tuner!).
While this model is perfect for my needs, it is relatively low powered for PA and stereo output applications, but the higher power versions in the DriveCore range have greater power needs well covered.
Great value for money. Highly recommended.
