If the PLM is at the end of a distribution line, its
setting should be Terminated. Otherwise, it should
be Unterminated. If an AES/EBU distribution
amplifier (DA) is being used to distribute the digital
audio signals, with one DA output per PLM, then all
terminations should be on. However, if the AES/EBU
link connectors are being used to "daisy-chain" the
PLM inputs together, then only the "last" PLM in the
chain should have its termination set on.
Once the Menu è
page is displayed, the rotary encoder can be used to
change the termination setting from Unterminated
to Terminated.

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 four
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

This submenu provides information and options
relating to the PLM as a physical unit. It is referred
to as a 'Frame' for consistency with Dolby Lake's
own terminology.

Display block 2 shows the Frame name if one has
been assigned; otherwise, a row of hyphens is
displayed. Assignment of a name to a Frame is only
possible from the DLC PLM Edition software.
