System Set-up and Installation
1.2 Breaking in Your New Preamplifier
Although your Viola Spirito preamplifier delivers outstanding
performance straight out of the box, you should expect to hear it continue
to improve as it reaches its normal operating temperatures and its various
components "break-in". It has been our experience that the greatest
changes occur within the first 25-50 hours, but that the preamplifier will
continue to improve in sound quality for about 300 hours, after which time
it remains quite constant.
The only exception to this rule is if power is removed from the unit,
allowing it to cool down. This can occur due to extended power outages,
unplugging the preamplifier supply from the wall during a vacation, or by
leaving the preamplifier in sleep mode rather than in standby. In these
cases you should expect a brief warm-up period before the amplifier's
sound quality is at its best. Fortunately, you will never have to repeat the
full 300-hour break-in period.
1.3 Placement Considerations
1.3.1 Ventilation
Important! For your protection, please review "Important Safety
Instructions", Section 1 above, before installing your preamplifier.
Your Viola Spirito preamplifier is specifically designed to accommodate a
wide range of installation options. This preamplifier may be placed near
the amplifiers or at an established distance. They may be located on
shelves, if indeed the shelves are sturdy enough to support the weight of
the preamplifier. The ventilation system employed by the Viola Spirito
preamplifier will maintain optimal operating temperatures even if the
preamplifier and supply are stacked one above the other.
The preferred configuration is to locate the preamplifier near the listening
position. This approach provides maximum comfort for the listener and
may necessitate longer interconnecting cables from the preamplifier to the
power amplifier. The advantage of this strategy lies in the fact that the
interconnecting cables carry low current signals that are more readily
transmitted over distances with great accuracy than are the necessarily
high current signals required between the amplifier and the loudspeakers.
Please note that adequate clearance for the AC cord and connecting signal
cables must be left behind your preamplifier. We suggest leaving at least
six inches (15 cm) of clearance behind your preamplifier so all cables have
sufficient room to bend without crimping or being subjected to undue
strain.
