6.4 LM Series Configuration Tutorial
This tutorial provides a step-by-step guide for configuration of a typical professional loudspeaker system
and provides an overview of the basic features and operation of LM Series devices. This tutorial uses
the Lake Controller software for configuration, although many steps are also available via the front panel
interface.
This tutorial describes how to configure a single LM 26 for use with a 3-way loudspeaker system (with
separate HF, MF and LF drivers), plus a separate Auxiliary output for feeding a subwoofer. It assumes the
use of an analog mixing desk, and that a dedicated subwoofer output is generated on the mixing console
itself using an auxiliary output send.
The following tutorial assumes use of a Tablet PC
and therefore the term TAP rather than CLICK is
used for activating commands.
1. Connect the amplifiers/powered loudspeakers to the four LM 26 output channels:
▸ Channel 1 – Low Frequency Driver
▸ Channel 2 – Mid Range Driver
▸ Channel 3 – High Frequency Driver
▸ Channel 4 – Subwoofer
2. Connect the main output of the mixing console (left or right channel as appropriate) to Analog
Input 1 of the LM 26. Connect the sub output from the mixing console to Analog Input 2.
3. Ensure the volume is turned down for both the main and sub send on the console and that no audio
is passing through the system.
4. Ensure the LM 26 is connected to a PC running the Lake Controller software.
5. After ensuring that no audio is being output from the mixing console, power on the LM 26.
6. On the Tablet PC, launch the Lake Controller software application. Select the appropriate network
adapter if more than one is enabled, and tap NO to the dialog asking whether to load the previous
configuration.
7. Tap MODULES to access the Module Menu and scroll bar.
8. On the Module scroll bar, the LM 26 is represented with a frame containing two discs. These are
labeled A and B and represent the two Lake processing modules.
