before the product is operated.
2 Retain instructions - The safety and operating instructions should be retained
for future reference.
3 Heed Warnings - All warnings on the product and in the operating instructions
should be adhered to.
4 Follow Instructions - All operating and use instructions should be followed.

liquid cleaners or aerosol cleaners. Clean only with a dry cloth.
6 Attachments - Do not use attachments not recommended by the product
manufacturer as they may cause hazards.
7 Water and Moisture - Do not use this product near water-for example, near a
bath tub, wash bowl, kitchen sink, or laundry tub; in a wet basement; or near a
swimming pool; and the like.
8 Accessories - Do not place this product on an unstable cart, stand, tripod,
bracket, or table. The product may fall, causing serious injury to a child or adult,
and serious damage to the product. Use only with a cart, stand, tripod, bracket, or
table recommended by the manufacturer, or sold with the product. Any mounting
of the product should follow the manufacturer’s instructions, and should use a
mounting accessory recommended by the manufacturer.
9 A product and cart combination should be moved with care. Quick
stops, excessive force, and uneven surfaces may cause the product and
cart combination to overturn.
10 Ventilation - Slots and openings in the cabinet are provided for ventilation and
to ensure reliable operation of the product and to protect it from overheating, and
these openings must not be blocked or covered. The openings should never be
blocked by placing the product on a bed, sofa, rug, or other similar surface. This
product should not be placed in a built-in installation such as a bookcase or rack
unless proper ventilation is provided or the manufacturer’s instructions have been
adhered to.
11 Power Sources - This product should be operated only from the type of power
source indicated on the marking label. If you are not sure of the type of power
supply to your home, consult your product dealer or local power company. The
primary method of isolating the amplier from the mains supply is to disconnect
the mains plug. Ensure that the mains plug remains accessible at all times. Unplug
the AC power cord from the AC outlet if the unit will not be used for several
months or more.
12 Grounding or Polarization - This product may be equipped with a polarized
alternating current line plug (a plug having one blade wider than the other). This
plug will t into the power outlet only one way. This is a safety feature. If you are
unable to insert the plug fully into the outlet, try reversing the plug. If the plug
should still fail to t, contact your electrician to replace your obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
13 Power Cord Protection - Power supply cords should be routed so that they
are not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords at plugs, convenience receptacles, and the
point where they exit from the product.
14 Outdoor Antenna Grounding - If an outside antenna or cable system is
connected to the product, be sure the antenna or cable system is grounded so
as to provide some protection against voltage surges and built-up static charges.
Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information
with regard to proper grounding of the mast and supporting structure, grounding
of the lead-in wire to an antenna discharge unit, size of grounding conductors,
location of antenna discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer’s attention to Section 820-40 of
the NEC which provides guidelines for proper grounding and, in particular, species that
the cable ground shall be connected to the grounding system of the building, as close to
the point of cable entry as practical.
15 Lightning - For added protection for this product during a lightning storm, or
when it is left unattended and unused for long periods of time, unplug it from the
wall outlet and disconnect the antenna or cable system. This will prevent damage
to the product due to lightning and power line surges.
16 Power Lines - An outside antenna system should not be located in the vicinity
of overhead power lines or other electric light or power circuits, or where it can
fall into such power lines or circuits. When installing an outside antenna system,
extreme care should be taken to keep from touching such power lines or circuits
as contact with them might be fatal.
17 Overloading - Do not overload wall outlets, extension cords, or integral
convenience receptacles as this can result in a risk of re or electric shock.
18 Object and Liquid Entry - Never push objects of any kind into this product
through openings as they may touch dangerous voltage points or short-out parts
that could result in a re or electric shock. Never spill liquid of any kind on the
product.
WARNING: THE APPARATUS SHOULD NOT BE EXPOSED TO DRIPPING
OR SPLASHING, AND OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES,
SHOULD NOT BE PLACED ON THE APPARATUS. AS WITH ANY ELECTRONIC
PRODUCTS, USE CARE NOT TO SPILL LIQUIDS INTO ANY PART OF THE
SYSTEM. LIQUIDS CAN CAUSE A FAILURE AND/OR A FIRE HAZARD.

INTRODUCTION
M52 Digital Music Vault provides a safe and convenient way to store your
music les. It presents enterprise-level protection for your valuable 24/96
music collection. When combined with the M50 Digital Music Player and
the M2 Direct Digital Amplier, or M51 Direct Digital DAC, this Masters
Series Digital Suite becomes the ideal way to enjoy HD music as well as
everything else in your music collection.
Using a Redundant Array of Independent Discs (RAID 5) technology, the
M52’s three hard disc drives (HDD) make it nearly impossible to damage
your music. Front panel LED indicators display the status of the HDDs, and
alert you if there is an HDD failure. Even if a disc drive fails, you won’t lose
data in this self-healing system. Simply replace the drive, and the system
automatically recongures itself.
