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.

SELECT THE INPUTS YOU ARE USING ON YOUR DIGITAL PROCESSOR
AND PREAMPLIFIER
Take care that a Tape Monitor switch does not override your selection of
the digital processor’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 Nº37 CD Transport 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 few hours as the Nº37 reaches thermal equilibrium. Depending on how cold
the Nº37 was when you first connected it to AC power, full thermal equilibrium
might take as long as a day or two, after which time 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 Nº37’s sound
quality is at its best. Unless your Nº37 was allowed to become quite chilled, sub-
sequent thermal re-stabilization should not take long.
