MartinLogan Descent [10/20] Ac power connection

10 Connections and Control Settings

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 Descent, then

to any convenient AC wall outlet. Directly above the AC

power receptacle on the rear connection panel of the Descent

is a master power switch. This switch is wired directly to the

AC main and turns on/off all power going to the Descent. The

Descent also integrates a signal sensing power supply that will

switch off after a few minutes of no music signal if the front-

panel power switch is set to 'Auto'.

Your Descent 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 Descent subwoofer from the country of

original sale, be certain that AC power supplied in any subse-

quent location is suitable before connecting and operating

the subwoofer. Substantially impaired performance or severe

damage may occur to the Descent subwoofer if operation is

attempted from an incorrect AC power source.

If the fuse in your Descent should require changing, turn your

Descent off and unplug it before removing the fuse. Replace

the bad fuse with a matching 7 Amp slow-blow fuse.

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.

After six months of use, you may find that the

mounting screws on your Descent need to be

tightened. To do this, use a

/8-inch allen tool.

If the

/8-inch allen tool does not fit a screw, that

screw requires no tightening.
