MartinLogan Speaker - Manual (Page 12)

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 Abyss, then to any convenient AC wall outlet . The
Abyss also integrates a signal sensing power supply
that automatically switches off after sensing no music signal
for several minutes (this will occur when the power switch
is set to 'Auto') .
Your Abyss subwoofer is wired for the power service supplied
in the country of original consumer sale . The AC power rat-
ing 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 Abyss subwoofer from the country of
original sale, be certain that AC power supplied in any sub-
sequent location is suitable before connecting and operating
the subwoofer . Substantially impaired performance or severe
damage may occur to the Abyss subwoofer if operation is
attempted from an incorrect AC power source .
If the fuse in your Abyss should require changing, turn off and
unplug your Abyss before removing the fuse . Replace the bad
fuse with a matching T 3 .15A L 250V (T 1 .6A L 250V if you
are in a region using 220v–230v current) .
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 .
