POWER UP THE REST OF THE SYSTEM, LEAVING THE POWER AMPLIFIERS
FOR LAST
Always turn the power amplifer(s) off first, and on last. This good habit
minimizes the opportunity for unexpected transients to be passed to your
loudspeakers. Another good habit is to reduce the volume on your pream-
plifier to minimum value before you restore power to the system.

SELECT THE INPUT YOU ARE USING ON YOUR PREAMPLIFIER
Take care that a Tape Monitor switch does not override your selection of
the CD player’s input on your preamplifier, or you will be struck by how
“quiet” your new digital source is.…

LOAD A DISC IN THE DRAWER AND PRESS PLAY; SLOWLY RAISE THE
VOLUME ON YOUR PREAMPLIFIER

Warm up/break-in period
Although your Mark Levinson Nº39 CD Processor delivers outstanding perfor-
mance 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 Nº39 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 cool-
ing involved, you should expect a brief warm-up period before the Nº39’s sound
quality is at its best. Unless your Nº39 was allowed to become quite chilled, sub-
sequent thermal re-stabilization should not take long.
