5.4. 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 these types of crossovers and information on configuring various module types can be found in
the LAKE Controller Operation Manual.
5.5. 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 as shown in on page 15. 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 associated
I/O routing.
5.6. Switching between Contour and Mesa Mode
When switching between Contour and Mesa Modes, all current Frame configuration data is lost (Presets are
retained) and the device is completely reconfigured into the selected Mode. Ensure you have stored any existing
frame configuration data before configuring into a different mode.
The device configuration may be changed either via the Front Panel MENU > FRAME > FRAME RST (refer to
section 6.9.4.2 of the LM Series Operation Manual) or via the LAKE Controller MODULES > I/O CONFIG > FRAME
CONFIG menu (refer to the LAKE Controller Operation Manual).
5.7. Files and Presets
The LAKE system provides various methods for storing and recalling Module, Frame, or system-wide data. An
overview is provided below; for further information please refer to the LAKE Controller Operation Manual.
