Although no damage is likely to result to either CD player or
preamplifier, the sound will be badly distorted and the volume may
be much louder than you expect.)
4a. If going direct from the Nº390S to an amplifier!
See Special Functions setup on page 47 to set the Nº390S to
variable output mode.
5. Power up the rest of the system, leaving the power amplifiers
for last.
Always turn the power amplifier(s) off first, and on last. This
good habit minimizes the opportunity for unexpected tran-
sients to be passed to your loudspeakers. Another good habit
is to reduce the volume on your preamplifier to minimum
value before you restore power to the system. When the
Nº390S is in its variable preamp mode, it powers up at a low
volume to minimize sudden changes in volume.
6. Load a disc in the drawer and press Play; slowly raise the
volume on your preamplifier.

Break-in Period Although your Mark Levinson Nº390S CD Processor 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 300 hours, as the Nº390S reaches thermal equilibrium
and capacitors become fully formed. After this initial break-in, its
performance will remain quite constant.
The only exception to this rule is if power is removed from the
unit for more than a few minutes, allowing it to cool down.
Depending on the degree of cooling involved, you should expect
a brief warm-up period before the Nº390S’s sound quality is at its
best. Unless your Nº390S was allowed to become quite chilled,
subsequent thermal re-stabilization should not take long.
