4 Break-in Period
Your new A VALON A COUSTICS loudspeakers have an initial break-in period. They
will not perform to their full sonic potential when first installed in your system.
This is partially due to a residual polarization of the dielectric materials used in
the crossover capacitors and internal wiring.
1 As music is played through the
loudspeakers, the electrical signal will gradually anneal these materials.
Similarly, the suspensions of the drivers will reach their optimal mechanical
properties as the speakers are played. Only after the break-in period will the
full performance of your A
VALON A COUSTICS loudspeakers be realized.
The break-in process will occur naturally as music is played through the
system. To reduce the time required, it is recommended that the system be
played continuously, using either a digital source in the repeat mode or an
FM broadcast signal. The recommended break-in procedure is as follows:
 Initial warm-up: three to six hours of quiet music.
 Extended break-in: 200 to 300 hours of loud and dynamic source
material (e.g. Tangerine Dream, Optical Race, RCA 2042-2-P).
During the break-in period, the sonic properties of your loudspeakers may
undergo several gradual shifts as the various components break-in at different
rates. It is therefore suggested that the fine-tuning of the system be delayed
until after the break-in period is completed. However, during the final phases
of the break-in period, the sonic image will open up, the sound-stage will gain
specificity, the bass control and impact will increase, and the overall sound
will have a more relaxed, involving presentation.
1 A high-voltage test is applied to wiring and capacitors during their manufacture.
This results in a residual polarization of the dielectric materials.
