Desired power can be specied in several domains: burst and peak power; peak and RMS voltage; and also
the speaker’s AES power rating. By specifying the nominal impedance of the load, the RPM algorithms have all
input data required to calculate resulting RPM settings. If the desired RPM settings taken together allow total
output higher than the capabilities of the amplier, RPM will reduce actual RPM conguration evenly based on a
proportional reduction in dB. Once applied, the RPM functionality will ensure that the channel is not delivering more
power than specied. The ISVPL limiter algorithm performs the actual limitation. As default, the smaller models in
the range have an RPM conguration detailing an equal shared power allocation cross the channels at a voltage
(default voltage limitation) given in the specication sheet. To prevent the risk of over-allocating the power supply
for varying or incorrect load impedances, RPM has a limitation for the smaller models in the range of the number of
channels that can be lifted above the default voltage limitation.

RPM can be congured in two modes:
RPM Off: In this mode RPM is disabled and power is shared equally among the channels. The default voltage
limitation is in place for all channels.
RPM ON: The CAFÉ software allows users to create an advanced custom power allocation scheme. Additional
information is available in documentation supplied with the CAFÉ software download.
CAFÉ with ESP: CAFÉ (Conguring Ampliers For the Environment) is a dedicated software application for
Windows and OSX that provides tools for system planning, specication and commissioning. CAFÉ incorporates
the Equipment Specication Predictor (ESP), a software module that examines SPL and speaker requirements
for a project and generates requirements for output power on an amplier and system level. ESP will generate a
custom RPM conguration for optimizing the power allocation within the frame. For more information on CAFÉ and
ESP, please consult the documentation supplied with the CAFÉ software download.
