5802 INTEGRATED AMPLIFIER / OWNER’S MANUAL
INSTALLATION
POWER REQUIREMENTS
The N
0
5805 is configured at the factory for 100, 115, or 230
VAC power operation at 50Hz or 60Hz. Before operating the
amplifier, ensure that the power label on the rear panel near
the AC input connector indicates the correct operating voltage.
A detachable IEC power cable intended for use in the region
where the
N
0
5805 / N
0
5802 is sold is included.
Connection to an AC voltage other than that for which the
N
0
5805 / N
0
5802 is intended can create a safety and fire hazard
and may damage the unit. If you have any questions about
the voltage requirements for your N
0
5805 / N
0
5802 or about
the line voltage in your area, contact your authorized Mark
Levinson dealer before plugging the N
0
5805 / N
0
5802 into an
AC power outlet.
WARNING! MAKE SURE all components in the audio system
are properly grounded. Do NOT defeat the safety purpose of
polarized or grounding-type plugs with “ground-lifter” or
“cheater” adapters. Doing so may cause a dangerous voltage
to build up between components, which may result in personal
injuries and/or product damage.
NOTE: The N
0
5805 / N
0
5802 is capable of delivering
remarkable sound at exceptional power levels. Depending
on your listening preferences, the demands of your
loudspeakers and the number of power amplifiers present
in your system, it is possible electrical service may become
the limiting performance factor in your system.
If this case occurs, consider installing a dedicated AC circuit
for the system. If more than one AC circuit is providing
power to your system, contact a licensed electrician to
ensure that all components are operating with the same
solid, low-impedance ground reference.
Unplug the N
0
5805 / N
0
5802 from the AC wall outlet during
lightning storms and extended periods of non-use.
CAUTION: Before moving the unit, make sure it is powered off
by removing the power cord from the AC power outlet and the
unit’s rear panel.
OPERATING STATES
The N
0
5805 / N
0
5802 has three operating states:
Off: The AC mains power is disconnected by removing the power
cord from the rear panel.
Standby: The Standby mode has three settings that can be
selected via the
Setup menu: Green, Power Save, and Normal.
(See page 22 for more information on changing
Standby mode
settings.)
Green: This mode removes power from almost all of the
amplifier’s circuits, allowing the unit to be activated only via
an IR control signal, a 5V – 12V trigger or a double press
of the
Standby button. This mode provides maximum power
conservation and is the factory-default
Standby mode.
Power Save: This mode removes power from the audio
circuits, but keeps the control circuitry powered and ready
to receive commands from the front panel controls, or the
remote control or the web-browser Graphical User Interface
(GUI). This mode provides moderate power conservation.
Normal: This mode shuts off the display and mutes its
audio outputs, but keeps all of its control and audio circuits
powered. This mode provides the least amount of power
conservation but allows the N
0
5805 / N
0
5802s audio circuits
to remain warmed up to deliver optimal performance at all
times.
On: The entire unit is powered up and all configured outputs
are active.
The N
0
5805 / N
0
5802 has an Auto Off feature that automatically
places it into the
Standby mode after 20 minutes of no user
control input or audio signal passing through the unit. The
factory default setting for the Auto Off feature is On (engaged)
as required for certain regions. You can disable the Auto Off
feature in the
Setup menu (see Setup on page 16).
