1
Toggle the Source from which you want to route the channels (Module, Analog, AES) (NOTE: that this also may
affect the destination, as only AES3 and analog can be routed to Dante.
2
Toggle up among the available source channels
3
Toggle down among the available source channels
4
Unused
5
Unused
6
Toggle left among the available outputs
7
Toggle right among the available outputs
8
Disconnect all assignments
9
Turn Right to Route / Turn Left to Un-route
Use the arrows visible on the display (2-3, 6-7) to toggle between available sources and outputs. Use the rotary
encoder to select the output you want to connect to (power outputs or Dante). Selected output is marked with an
“X” when routed and “O” when not routed.
Selecting 8 brings up a warning screen.
7.11.4. Attenuation Submenu
MENU > ATTENUATION
The default setting of 0.00 dB (i.e. no attenuation) is adjustable in 0.25 dB increments down to -100 dB.
Adjustment of attenuation at the input to the PLM+ power stage is available on a per-channel basis. This
adjustment is the PLM+ equivalent of a conventional amplier level control. The power output channels may be
turned down using these parameters before powering on or off. Please refer to the signal ow diagram in
Figure 6.2.
By default, all channels are deselected. Press the SEL ALL button to select/deselect all channel, or, press a single
button on the right to adjust a channel individually.
Note: Only ONE channel or ALL channels may be adjusted. It is not possible to adjust only two or three
channels.
7.11.5. Frame Submenu
MENU > FRAME
The Frame Menu provides information and options relating to the device PLM+ as a physical unit. It is referred to
as a Frame for consistency with Lake Controller terminology.
The Frame Label as dened in the Lake Controller is displayed in this menu. It is also displayed at the top-left of the
screen in Meter Mode, Home View.

7.11.5.1. Frame Info
MENU > FRAME > FRAME INFO
Firmware Version (FW Version)
Further internal version numbers are displayed on right side of screen; Bundle, DSP, FPGA and Safe Image version.
Serial Number (Serial No.)
The printed serial number on the back panel of the PLM+ is also electronically embedded in the hardware, and
therefore cannot be removed or altered if stolen.
Default Output Voltage (DefOutVolt)
Displays the default output voltage per channel that can exist across the PLM+’s output terminals. This is the
absolute maximum, only the voltage defined by the ISVPL setting. The voltage can go higher with RPM;
see the technical data sheet for actual maximum voltage.
Note: When Bridge Mode is activated, double the channel output voltage is available.
Max Output Current (MaxOutCurr)
Displays the maximum output current that can be delivered by the PLM+, summed across all output channels.
7.11.5.2. Frame Reset and Configuration
MENU > FRAME > RESET
Use this option to display a further menu with options to reset all parameters back to their original factory default
values. See section 9.3 for a full list of the default factory reset parameter values. Two types of reset are provided:
Factory Reset and Soft Reset.
Factory Reset
the deletion of any Frame Presets stored within the device. It also resets the IP Address and all network related
settings including the Dual Redundancy setting; a hard power cycle is required to complete this reset.
Soft Reset
