This device provides control, monitoring and digital audio functionality via an Ethernet network.
For further information on the setup and configuration of an Ethernet network, please refer to the
Lake Controller Operation Manual and the Lake Network Configuration Guide.
6.4 PLM 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 PLM 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 4-channel PLM 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 example uses a hypothetical loudspeaker to illustrate the principles involved. No speaker–specific data
or LoadLibrary Fingerprint is included in the crossover configuration. Please also note that, for the purposes
of this tutorial, it is possible to connect small full-range cabinets ensuring close attention is given to steps
31 to 40 to avoid excessive power levels that could damage the loudspeakers.
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 loudspeakers to the four power 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 PLM. 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 PLM is connected to a PC running the Lake Controller software.
