Menu System Mark Levinson
If there is information that would normally be presented to the aux
outputs (for example, in a Surround•EX sound track), this setting
will cause it to be redirected to the available pair of surround
speakers to ensure that you do not miss anything in the
soundtrack.
Extra mono subwoofer only
Select the “extra mono sub only” option for the auxiliary channels
if you have a standard 5.1 channel system, but prefer to use two
separate subwoofers.
The extra subwoofer is a second, mono channel that is identical to
the main subwoofer output in content, but which has its own
distance and level setting adjustments. This is often the best way to
achieve maximally uniform and accurate bass response in a room.
Playing the same information in carefully chosen, staggered loca-
tions in the room minimizes the adverse effects of room modes on
bass reproduction. Please consult with your dealer on the best way
to take advantage of this capability in your particular room.
Specifically, in this setting:
• The subwoofer channel becomes the sub #1 channel
• The aux 1 channel remains unused
• The aux 2 channel becomes the sub #2 channel.
In this case, the sub #1 and the sub #2 outputs contain the same
information, but operate with independent distance and level
settings, indicated by “sub #1” and “sub #2” in the menu system
when this option is selected.
Stereo left subwoofer only
Some installations require separate left and right subwoofers, rather
than two mono subwoofers. This is partly a matter of preference,
and sometimes a matter of speaker design philosophy. If your
system requires this approach but does not require a surround back
(Sb), select “stereo left sub only” from the menu.
In this case, the aux 2 output becomes the left subwoofer output,
and contains all redirected bass from any speakers on the left side of
the room that are bass-limited; in addition, it contains one-half of
the center channel’s redirected bass (if any), and one-half of the low
frequency effects (LFE) channel (if any) in discrete multichannel
soundtracks.
