NEXT — selecting this in the first layer produces a second layer of calibration options:
Selecting ALS or ARS or ALF allows you to trim the Left Surround, Right Surround or LFE channels respectively
by ±10db, using the method described above.
LFG — This stands for Low Frequency Gain and allows the gain of the contribution from the full bandwidth channels
to the subwoofer output to be adjusted. Like all the speaker calibration settings it must be set for each set of
speaker outputs (assuming Bass Management is in use).
Having lined up the six main speakers, select LFG. In LFG mode all speakers are initially muted, and the six monitor
cut buttons will light; uncut the left output, and with the bass management turned on (note that the BMN selection
in the BASS menu is duplicated in the CAL menu), adjust the LFG gain for a flat low end response. Cut the left
output, uncut the right output, and check this has a flat low end response. Repeat for all channels. Depending on how
well matched the monitors are, you may have to adjust the LFG gain slightly.
Note that when LFG is on, the LFE monitor output is always cut. This does not mute the actual subwoofer output,
only the LFE signals feeding it. This ensures that you are only measuring the contribution from the Bass Management
system.
