MartinLogan Depth subwoofer - Manual (Page 12)

12 Connections and Control Settings
WARNING! The power cord should not be
installed, removed, or left detached from the
subwoofer while the other end is connected to
an AC power source.
The IEC power cord should be firmly inserted into the AC
power receptacle on the rear connection panel of the Depth,
then to any convenient AC wall outlet. The Depth also
integrates a signal sensing power supply that will switch off
after a few minutes of no music signal if the power switch
is set to 'Auto'.
Your Depth subwoofer is wired for the power service sup-
plied in the country of original consumer sale. The AC power
rating applicable to a particular unit is specified both on the
packing carton and on the serial number plate attached to
the subwoofer.
If you remove your Depth subwoofer from the country of
original sale, be certain that AC power supplied in any subse-
quent location is suitable before connecting and operating
the subwoofer. Substantially impaired performance or severe
damage may occur to the Depth subwoofer if operation is
attempted from an incorrect AC power source.
If the fuse in your Depth should require changing, turn your
Depth off and unplug it before removing the fuse. Replace
the bad fuse with a matching 5 Amp slow-blow fuse.
Break-In
Our custom made woofers require approximately 50 hours
of break-in at moderate listening levels before their optimal
performance occurs. This will factor in on any critical listening
and judgment.
After six months of use, you may find that the
mounting screws on your Depth need to be
tightened. To do this, use an 1 / 8 -inch allen tool.
Do not tighten screws on your Depth that do not
accept an 1 /
8
-inch allen tool.
