4 Break-in Period
Your new Avalon MultiChannel Systems 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.

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 Avalon MultiChannel Systems
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: 100 to 150 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.

A high-voltage test is applied to wiring and capacitors during their manufacture. This results
in a residual polarization of the dielectric materials.
