Unpacking Your Amplifier
Warning! Under no circumstances should you consider unpacking your
amplifier without adequate assistance, as both personal
injury and damage to the product is likely unless you follow
the procedures listed below.
The shipping weight of your Dual Monaural Power Amplifier is over 100 lbs. (45
kg)—the Nº333, for example, weighs in at 150 pounds (68 kg)! Any freight this
massive must be handled with extreme care to avoid injury. At least two strong
people are required to unpack these amplifiers safely.
Included with your new Mark Levinson amplifier is two pairs of knit, white
gloves designed to assist you in the initial unpacking and placement of your new
purchase. Please accept them as a token of our appreciation for having purchased
one of our products.
Caution! Do not attempt to lift your power amplifier from its packing
carton alone.
Never attempt to lift your power amplifier while bending from
the waist.
Always stand as straight as possible and use your leg muscles
to lift your amplifier.
After unpacking your power amplifier, keep all packing materials for future
transport. In the event that you need to ship your amplifier, only the original,
purpose-designed shipping carton is acceptable. Any other method of shipping
this heavy product will almost certainly result in damage to the amplifier—dam-
age that would not be covered by the warranty.
Carefully inspect your amplifier for possible damage due to shipping. If you dis-
cover any, contact your Mark Levinson dealer immediately.
Warm up/break-in period Although your Mark Levinson 300-series power amplifier delivers outstanding
performance straight out of the box, you should expect to hear it continue to im-
prove 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 amplifier 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. In this case you should expect a brief warm-up period before the
amplifier’s sound quality is at its best. (Fortunately, you will never have to repeat
the full 300 hour break-in period.)
