Placement Considerations
PRECAUTION
For your protection, review “Important Safety Instructions” and
“Operating Voltage” before you install your Nº33.

Your Mark Levinson Nº33 power amplifiers are specifically designed to stand on
the floor, and must be used as freestanding units. In most installations, locating
them near the loudspeakers is best. Obviously, this approach minimizes the
length of the speaker wires and necessitates longer interconnecting cables from
the preamplifier to the power amplifiers. The advantage to this strategy lies in the
fact that the interconnecting cables carry low-current signals which are more
readily transmitted over distances with great accuracy than are the necessarily
high current signals required by loudspeakers.

Note that adequate clearance for the AC cord and connecting signal cables must
be left behind each Nº33. We suggest leaving at least six inches (15 cm) of free
space behind each Nº33 so that all cables have sufficient room to bend without
crimping or undue strain.

Each amplifier should also be placed in such a way that the power switch on the
rear panel is easily accessible. This switch disconnects power from even the su-
pervisory power supply, resulting in effective disconnection of the amplifier from
the AC mains. (Note that under these conditions, the amplifier cannot respond to
remote-turn-on commands, etc.)

Ventilation
Your Mark Levinson Nº33 power amplifiers have been designed to complement
your listening room visually, with a tall and narrow frontal area which reduces
their effective “footprint” and makes them far more presentable than would be
the case with a more traditionally proportioned design. As a result, they can be
more easily placed beside your loudspeakers. As freestanding units, the Nº33 am-
plifiers normally will have no problem with ventilation.

plifiers normally will have no problem with ventilation.
Each of your Nº33 power amplifiers dissipate approximately 800 watts of energy
as heat when “at idle.” It is therefore normal and perfectly safe for them to run
warm. They do, however, require free air flow around them to allow adequate
heat dissipation through air circulation. The top plate and heatsinks of the Nº33
must be kept free from any obstruction which would reduce the free flow of air.

If your amplifier must be located inside an enclosure of some sort that restricts
airflow, we strongly advise using some fans to increase ventilation through the
enclosed space. If the amplifiers become too warm to touch, they are receiving
inadequate ventilation. While they are fully protected against overheating, no one
enjoys interrupted listening sessions.
