Getting Started Mark Levinson

Power Requirements

Mark Levinson products are factory-set for 100V, 120V, 220V, 230V

or 240V AC mains operation at either 50 or 60Hz, based on the

country for which they are manufactured.

If you have more than one circuit feeding the system with power,

please ask your electrician to ensure that they are all operating with

a solid, low impedance ground reference that is the same for all

products in the system.

The operating voltage of the Nº40 cannot be changed by the user,

and any attempt to do so will void the warranty. If you need to

change the operating voltage of your Nº40, or if the voltage indi-

cated on the rear panel label is not available in your area, contact

your Mark Levinson dealer for assistance.

Break-in Period

Although your Mark Levinson Nº40 Media Console delivers

outstanding performance 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 25-

50 hours, but that the system will continue to improve in sound

quality for about 300 hours, after which time it remains quite

constant.

The only exception to this rule is if power is removed from the unit,

allowing it to cool down. This can occur beacause of:

• Extended power outages

• Unplugging the product from the wall during a vacation

• Using the front panel power buttons rather than one of the

standby buttons.

In these cases you should expect a brief warm-up period before the

sound quality is at its best. (Fortunately, you will never have to

repeat the full 300 hour break-in period.)

Operating States

The Nº40 has three operating states:

• Off AC mains power is disconnected using the front

panel power button or by unplugging the unit

from the wall.

• Standby The Nº40 is powered up, but audio outputs are

muted and video outputs are either off or fed a

“black screen” signal (sync but not picture infor-

mation).

• On Everything is powered up and outputs are active.
