Audio Note AN-J - Manual (Page 11)

Once all the connections are completed and checked, ensure that the volume control
for your amplifier is at the minimum setting. Connect your amplifier to the mains
supply, and make sure all source components are switched on BEFORE the
amplifier; to protect youʼre AN-J loudspeakers from damage, always make sure the
amplifier is the LAST piece of equipment to be switched on and the FIRST to be
switched off.
Bedding in
While we fully expect your AN-J loudspeakers to produce
beautiful music, they may not do so from the first moment out
of the box. Donʼt be alarmed; this is perfectly normal.
Dynamic loudspeakers have a running in period, during which
time the drive units “loosen up”. During this period, the sound
may be somewhat dry, bright and constricted. As the
suspension and cone materials of both drive units “softens up”,
the fullness of the bass and the smoothness of the treble will
start to emerge and the true sound of the AN-J will be revealed.
We expect the AN-J to have a running in period of around 100
hours, which for the average listener will take about a month,
based on three hours of listening per day. This period can
however vary considerably due to factors such as music types,
listening volume and type of amplification used. (Loud heavy
metal or Mahler symphonies are especially effective!)
If the rest of your system is of commensurate quality, you may
notice that when you havenʼt played your AN-J for a week or
longer, they seem to experience a lesser version of this
running-in process again. Everything will be completely back to
normal within 5 to 10 hours.
Cleaning
No special maintenance is required for your AN-J
loudspeakers. Use a soft, clean lint free cloth to remove any
surface marks from the cabinets. For finger marks / grease,
use a soft, clean lint free cloth, very lightly moistened with a
solution of warm water and mild detergent. Do not use any
alcohol or solvent based cleaning products, as they may
damage the finish of the cabinet.
Under no circumstances should you attempt to clean the
drive units of your loudspeaker.
Playing some loud music will displace any dust that has
collected on the drive units!
