5.4.2 Super Modules
Super Modules allow control of multiple Modules of the same type, distributed across multiple Frames, as
a single entity within the Lake Controller software. A change made in the Super Module is replicated across
all assigned Modules, resulting in improved efficiency in system configuration and a reduction of on-screen
icons within the Lake Controller software.
The key benefit of this feature is the ability to connect and control crossovers, levels and EQ across multiple
hardware devices simultaneously from the Lake Controller. For example, one device may be driving sub and
low-frequency speakers, while another device controls mid-range and hi-frequency drivers. Using a single
adjustment the crossover points between the two devices can be changed simultaneously.
Please refer to the Lake Controller Operation Manual for further information regarding Super Modules.

Loudspeaker Processor (Contour Mode) Overview

In Contour Mode, LM Series devices may be configured with up to two processing Modules containing a
total of up to six processing Module outputs as shown in Figure 5-1 on page 11. Each set of processing
elements is referred to as a Module and can be configured as crossovers, full-bandwidth auxiliary outputs,
or a combination of the two. The relationship between inputs and outputs is defined via the Lake Controller
or via the front panel I/O CONFIG Menu.
The Lake Processing system provides two distinct categories of crossovers:
▸ Infinite Impulse Response filters (IIR) such as the classic Bessel, Butterworth or Linkwitz-Riley types;
these are available with slopes ranging from 6 dB/octave to 48 dB/octave.
▸ Finite Impulse Response filters (FIR) providing zero phase shift with steep transition slopes at the
crossover frequencies. These are also referred to as Linear Phase Crossovers.
Further details on crossovers and module types is available in the Lake Controller Operation Manual.

System Equalizer (Mesa Mode) Overview

In Mesa Mode, an LM Series device provides four processing Modules with independant EQ, HPF/
LPF, Gain, Polarity, Delay and Limiters. The relationship between inputs and outputs is defined via the
Lake Controller or via the front panel I/O Input Config Menu.
Please refer to the Lake Controller Operation Manual for addiitonal information on Mesa Mode and associ-
ated I/O routing.
