WARNING
To reduce the risk of fire or electrical shock, do not expose this apparatus to rain or moisture.
This symbol of a lightning flash inside a triangle is intended to alert the user to the presence of
uninsulated “dangerous voltages” within the player’s enclosure that may be of a magnitude so as to
constitute a risk of electrical shock.
This symbol of an explanation point inside a triangle is intended to alert the user to the presence of
important operating and safety information in the documents accompanying the player.
This warning indicates that the marked surface and adjacent surfaces can attain temperatures that
may be hot to the touch.
This symbol indicates the proper attachment point for the protective earth safety ground. In the
case of any repairs being conducted by a qualified electrical repair technician, the wire connecting
the earth terminal of the IEC power socket to the chassis must be connected only to the attachment
point indicated by this symbol.
See all safety markings on bottom/back of product.

Important Safety Instructions
1. Read this instruction manual in its entirety before operating the equipment. Keep the manual for future
reference.
2. Observe all safety precautions, warnings and instructions noted in this manual.
3. WARNING – To reduce the risk of fire or electric shock, do not expose this equipment to moisture. Keep
this device away from sources of water such as pools, bathtubs and sinks. Do not expose to rain, dripping/
splashing water or sprayed liquids. Do not place objects filled with liquids on the top.
4. Unplug from power source before cleaning. Clean only with dry cloth.
5. This product requires ventilation to operate properly. Do not block the fan opening or the vents on the
side of the chassis. Maintain at least 4” clearance on all sides and top.
6. Keep this product away from sources of heat and open flame such as radiators, heat registers, stoves, or
other apparatus (including amplifiers) that produce heat.
7. Make sure that the power cord is intact and undamaged before using it. Do not use cords with visible
damage to the insulation or end connectors. Protect the power cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
8. This device is equipped with a safety feature that requires the use of a three-pin grounding plug. Do not
defeat the safety purpose of the grounding plug by using an adapter or any other means such as removing
the third, grounding prong. If the provided plug does not fit your outlet, consult an electrician about replacing an obsolete power outlet or obtain the proper IEC power cord for your area.
9. Install in accordance with the manufacturer’s instructions.
10. Do not attempt to operate if the unit has been damaged in any way.
11. Only use attachments/accessories specified by the manufacturer.
12. Unplug this apparatus during lightning storms or when unused for long periods of time.
13. CAUTION – RISK OF ELECTRIC SHOCK! DO NOT OPEN! There are no user serviceable parts inside. Refer
all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in
any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into
the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been
dropped.

14. WARNING – Due to the potential for hot surfaces and high sound pressure levels, this equipment is not
suitable for use in locations where children are likely to be present.
Compliance Statement
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment on and o, the user is encouraged to try and correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Recycling Information
This symbol indicates this product is classified as Waste Electrical and Electronic Equipment (WEEE) in the
European Union and should not be discarded with household waste. Other territories may vary.

Before using your amplifier:
Verify your AC Circuit Voltage and Capacity:
This amplifier is configured at the factory to accommodate one of two line voltages: 100-120VAC or 220240VAC. Check the label on the back panel near the IEC power cord connector to determine the voltage
for which your amplifier is configured. Be sure it matches your local line voltage before plugging in. In the
event of a mismatch, contact your local distributor/dealer or contact the factory directly. There are no user
serviceable parts inside the chassis. Do not attempt to open the product or service it yourself.
Under maximum load conditions this amplifier may require heavy current draw. To insure proper
performance and avoid potential safety hazards, connect only to circuits that can provide a minimum of
15 amps of current. Avoid connecting to the same circuit as other high-current consumers such as heating
devices, microwave ovens and high-wattage lighting as this may cause circuit breakers or fuses to blow.
Avoid connecting any audio equipment to the same circuit as equipment with motors such as compressors,
refrigerators or air conditioners as this can cause high levels of unwanted noise in your sound or dips in
power as motors start up.
Set up:
Place the unit on a firm, level surface. Do not plug or unplug an instrument or speaker while the amplifier is
turned on.
Heat and Ventilation:
Make sure to allow space around the sides. Back and top for air circulation. Avoid use in extremely hot
locations with direct exposure to sunlight or placement near heating equipment. Avoid use in moist or high
humidity areas. Do not block fan opening or vent holes on the side. Allow for adequate air flow and do not
place coats or blankets over the amplifier.
