AC Power Connection

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.

Replacing the Fuse

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.
