24. if any of the settings differ from the above,
please refer to the Dolby Lake Controller user
Manual PLM Edition addendum for guidance
on changing them.
25. The next step is setting the pLM's gain
structure. in a real situation, the loudspeaker
manufacturer's data should be consulted for
information regarding the relative drive levels,
crossover specifications and limiter settings for
the LF, MF, HF and sub channels. alternatively,
a Lab.gruppen LoadLibrary file would have been
used that would already contain the necessary
data to configure gain, crossover and limiter
settings. the default settings for the Dolby
Lake processing Module inputs and outputs are
0 dB, and for the amplifier gain, 35 dB. We will
assume that these settings are satisfactory for
this illustration. from the I/O Config screen,
tap the Lab.gruppen Info button on the
menu bar. the PLM Series Module Status tab
should open. if a different tab opens (the last
accessed always opens), tap the Status tab
to switch to it.
26. the four fader strips displayed represent the
four power output channels, as connected to
the four Module outputs in use. in accordance
with the settings made in output Configurations
in Step 22, the four strips represent Low, Mid,
High and aux respectively. the four faders
are the amplifier attenuation controls. as a
precaution, move them all to the minimum
position. Close the page with the Return
button.
27.
Tap on the Input Gain block
pane. the left-most of the five faders now
shown on-screen is the Module input gain; the
others are the Module output gains. For the
purposes of our hypothetical loudspeaker, set
the Mid fader 6 dB below the Low fader and
the high fader 12 dB below the Low fader.
the Module input is still muted. Un-mute it by
tapping the Input Mute button (it turns blue).
feed the pLM with audio by slowly opening
fader(s) on the mixing desk. the bargraph
meters on-screen should indicate signals.
Adjust the Module Input gain if necessary to
obtain an appropriate signal level on the output
bargraphs. Close the page by tapping EQ/
Levels EXIT on the menu bar. the i/o Config
screen will be displayed again.
