The N
0
52 has been designed for use with 100 – 240-volt,
50Hz/60Hz AC (alternating current), with a maximum current
draw of 65W. It includes a detachable IEC power cable
intended for use in the region where the N
0
52 is sold.
Connection to an AC voltage other than that for which the
N
0
52 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
52 or about the line voltage
in your area, contact your authorized Mark Levinson dealer
before plugging the N
0
52 into an AC power outlet.
caUtioN: although your
N
0
52
will operate from 100V – 240V,
50Hz/60Hz ac, operating it from a voltage that is different
from that where the unit was originally shipped and sold
may require the use of a power cord that is different from
the one supplied with your
N
0
52
. contact your authorized
mark levinson dealer for additional assistance.
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
dangerous voltage to build up between components, which
may result in personal injuries and/or product damage.
operatiNg states
The N
0
52 has three operating states:
off: The AC mains power is disconnected using the
Controller’s rear-panel Power switch or by removing the
power cord from the Controller’s rear panel.
standby: The N
0
52 Standby mode has three settings that
can be selected via the Setup menu: Green, Power Save,
and Normal.
Green: This mode removes power from almost all of the
N
0
52’s circuits, allowing the unit to be activated only via an
IR control signal, a 5V – 12V trigger or a 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 N
0
52’s
audio circuits, but keeps the control circuitry powered
and ready to receive commands from either the front
panel controls or the remote control. This mode provides
moderate power conservation.
Normal: This mode shuts off the N
0
52’s 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
52’s audio circuits
to remain warmed up to deliver optimal performance at
all times.
on: The entire N
0
52 is powered up and all configured
outputs are active.
The N
0
52 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). You
can turn the Auto Off feature off (disengaged) in the Setup
menu. See the
N
0
52 User Guide for details.
You should unplug the N
0
52 from the AC wall outlet during
lightning storms and extended periods of non-use.
caUtioN: BeFore moving the N
0
52, make sure it is
powered off with the controller’s rear-panel power
switch. then make sure the power cord is disconnected
from the controller’s rear-panel connector and the ac
power outlet.
