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 Descent 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 10A H 250V (T 5A 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.
