Auto RPM: The frame will automatically allocate power per output channel according to the ISVPL settings in the
speaker preset (per module output) in Lake Controller. Auto RPM assumes a nominal impedance of the Load and
applies an approximate power allocation. Auto RPM is default for D Series Lake.
Custom RPM: The CAFÉ software allows users to create an advanced custom power allocation scheme.
Switching to Custom mode disables the Automatic mode. Additional information is available in documentation
supplied with the CAFÉ software download.
Custom RPM using CAFÈ with ESP: CAFÉ (Configuring Amplifiers For the Environment) is a dedicated software
application for Windows and OSX that provides tools for system planning, specification and commissioning. CAFÉ
incorporates the Equipment Specification Predictor (ESP), a software module that examines SPL and speaker
requirements for a project and generates requirements for output power on an amplifier and system level. ESP will
generate a custom RPM configuration optimizing the power allocation within the frame. For more information on
CAFÉ and ESP, please consult the documentation supplied with the CAFÉ software download.
11.3. Amplifier and Load Protection Systems
The D Series is equipped with a comprehensive set of protection circuits. If operating conditions become
sufficiently extreme that any of these circuits become active, indication is provided by amber or red LEDs on the
front panel, and by text notifications in the Lake Controller and CAFÉ software. Refer to Section 14.1 for more
information on warnings and faults.
