MartinLogan CW10 - Manual (Page 8)

8 Connections and Control Settings
AC Power Connection Replacing the Fuse
The power cord should be firmly inserted into any conve-
nient AC wall outlet. The CW10 also integrates a signal
sensing power supply that automatically switches off after
sensing no music signal for several minutes (this will cause
the status LED to turn off).
Your CW10 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 CW10 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 CW10 subwoofer if operation is
attempted from an incorrect AC power source.
If the fuse in your CW10 should require changing, turn off
and unplug your CW10 before removing the fuse. Replace
the bad fuse with a matching T 1.6A L 250V (T 0.8A L
250V if you are in a region using 230V).
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.
