RPM helps to avoid amplifier over-specification, or bridging
of adjacent channels in order to meet minimum demands
on one power-hungry load, which would otherwise result in
a loss of channel count. RPM technology also enables the
user to minimize equipment costs, reduce rack space and
improve long-term energy efficiency – all achievable without
compromising sonic performance.
Rational Power Management provides true flexibility of power allocation
Rational Power Management:
Optimal performance and minimal
equipment costs
Rational Power Management incorporates features that
safeguard the defined power output of one or more specified
channels. From within the CAFÉ software, it allows the
desired power demand to be calculated for the different loads
in several different ways. RPM then analyses the desired
power in relation to the channel and device constraints and
guides the system designer towards the most effective way
of powering the PA.

ional Power Management results in real-world savings,
both immediate and long-term. In many cases, fewer
amplifiers – or lower cost models – may be specified while
still fulfilling all power requirements.
It also allows better mains management, avoiding over-
specification of mains distribution, cooling, and UPS (where
required). Finally, the overall gains in efficiency in larger
systems will minimiz
e current consumption and reduce
operation costs – a “green bonus” for the system owner.

For the first time, RPM provides true flexibility in allocating
available power across the four output channels. Each
channel of the 12K44, for example, may be tailored to meet
the requirements of the connected load, and any power not
used for that channel may be allocated for use on other
channels.
On top of the outstanding performance users have come to
expect from a PLM, the 12K44 and 5K44 models also
features Rational Power Management (RPM), a proprietary
Lab.gruppen technology that provides designers, systems
techs, consultants and integrators with unprecedented
freedom to allocate the available output power of each
amplifier channel for optimum performance ith specific
load conditions.
