Replacing the Fuse
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 cord should be firmly inserted into the AC
power receptacle on the rear connection panel of the
subwoofer, then to any convenient AC wall outlet.
Directly adjacent to the AC power receptacle on the rear
connection panel of the subwoofer is a master power
switch. This switch is wired directly to the AC main and
turns on/off all power going to the subwoofer. The Depth
i also integrates a signal sensing power supply that will go
to Standby mode after a few minutes of no music signal if
the front-panel power switch is set to 'Auto'.
Your 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 subwoofer from the country of original
sale, be certain that AC power supplied in any subsequent
location is suitable before connecting and operating
the subwoofer. Substantially impaired performance or
severe damage may occur to the subwoofer if opera-
tion is attempted from an incorrect AC power source.
If the fuse in your subwoofer should require changing,
turn your subwoofer off and unplug it before removing
the fuse. Replace the bad fuse (figure 15) with a matching
T 4A H 250V (T 2A L H 250V if you are in a region using
230v–240v mains voltage).
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.
