Adjustment of attenuation at the input to the PLM’s power stage is available on a per-channel basis. This
adjustment is effectively the PLM’s equivalent of a conventional level control. The PLM may be turned “right
down” with this adjustment before powering on or off. See the signal flow block diagram (figure 8.1).
The default setting is 0 dB (i.e. no attenuation), but this may be varied in 0.25 dB increments down to -100
dB. (Note that the minus sign means the display is strictly showing gain rather than attenuation).
On entering the submenu, the default is for all channels to be deselected. Soft button 4,
Sel All
, selects all
channels; a second press deselects them. Alternatively, individual channels may be adjusted independently
by selecting them one at a time with soft function buttons 5-8. Note that it is not possible to adjust attenua-
tion for two or three channels: only one channel or all channels may be adjusted at one time.

This submenu provides information and options relating to the PLM as a physical unit. It is referred to as a
‘Frame’ for consistency with Lake’s own terminology.
9.13.5.1 Frame label
Display block 2 shows the Frame label if one has been assigned; otherwise, a row of hyphens is displayed.
Assignment of a name to a Frame is only possible from the Lake Controller software. Default Frame name is
the model name (i.e. 10000Q or 14000).
