Audio Note AZ-Two Speaker - 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 your AZ-TWO 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 AZ-TWO 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 AZ-TWO will be
revealed.
We expect the AZ-TWO 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 AZ-TWO 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 AZ-TWO
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!
