5302 POWER AMPLIFIER / OWNER’S MANUAL
INSTALLATION
POWER REQUIREMENTS
The N
0
5302 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
5302 is sold is included.
Connection to an AC voltage other than that for which the
N
0
5302 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
5302 or about the line
voltage in your area, contact your authorized Mark Levinson
dealer before plugging the N
0
5302 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.
Unplug the N
0
5302 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.
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 14 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 a wired 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 web-browser Browser Setup Page (BSP). This mode
provides moderate power conservation.
Normal: This mode mutes the amplifier’s 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
5302’s audio circuits to remain warmed
up to deliver optimal performance at all times.
ON: All circuits are fully powered.
Auto Off: The N
0
5302 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 (auto-off engaged) as required for certain
regions. You can disable the Auto Off feature in the Setup
menu (see page 14).
