Active Power Management™
Active Power Management™ is inspired by the nature and response of tube amps and is in
essence an adaptive part of the amp that actively reacts to the source signal.
Active Power Management™ is controlling an integrated circuit that kicks in when the amp gets
close to its maximum performance and starts to compress and limit the peaks of the bass signal
similar to the way a tube amp would do. We have spent numerous hours tweaking and tuning this
circuit to optimize the performance and sound of it (fig.5).
The result is an amp that, regardless of how hard it is pushed, will not go into ‘transistor’ clipping
and will have a higher perceived level pr. Watt similar to what is known as ‘tube watt’.
