IMPORTANT SAFETY INSTRUCTIONS
1. Read instructions — All the safety and operating instructions should be
read before the amplifier is operated.
2. Retain instructions — The safety and operating instructions should be
retained for future reference.
3. Heed Warnings — Adhere to all warnings and precautions listed on the
amplifier and in the operating instructions.
4. Follow instructions — Follow all operating instructions.
5. Water and Moisture — The amplifier should never be used next to water —
for example, near a bathtub, kitchen sink, laundry tub, in a wet basement,
or near a swimming pool, etc.
6. Carts and Stands — The amplifier should be used only with a cart or stand
that is recommended by the manufacturer.
• An amplifier and cart combination should be moved with care. Quick
stops, excessive force, and uneven surfaces may cause the amplifier and
cart combination to overturn.
7. Caution — To prevent electric shock, do not use the amplifier’s polarized
plug with an extension cord, receptacle or other outlets unless the blades
can be fully inserted to prevent blade exposure.
8. Ventilation —The amplifier should be situated so that its location does not
interfere with its proper ventilation. For example, the amplifier should not
be situated on a bed, sofa, rug, or similar surface that may impede the flow
of air through the ventilation openings.
9. Heat — The amplifier should be situated away from heat sources such as
radiators, heat registers, stoves, or other appliances (including other
amplifiers) that produce heat.
10. Power sources — The amplifier should be connected to a power supply
only of the type described in the operating instructions or as marked on
the amplifier.
11. Grounding or Polarization — Precautions should be taken so that the
grounding or polarization means of the amplifier are not defeated.
12. 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 amplifier.
13. Cleaning — The amplifier should be cleaned only as recommended by the
manufacturer.
14. Non-Use Periods — The power cord of the amplifier should be unplugged
from the outlet when left unused for a long period of time.
15. Object and Liquid Entry — Care should be taken so that objects do not fall
and liquids are not spilled into the enclosure through the openings.
16. Damage Requiring Service — The amplifier should be serviced by
qualified service personnel when:
a. The power-supply cord or the plug has been damaged
b. Objects have fallen, or liquid has been spilled into the amplifier
c. The amplifier has been exposed to rain
d. The amplifier does not appear to operate normally or exhibits a marked
change in performance
e. The amplifier has been dropped, or the enclosure damaged
17. Servicing — The user should not attempt to service the amplifier beyond
that described in the operating instructions. All other servicing should be
referred to qualified service personnel.

UNPACKING
Save the carton and the styrofoam inserts for future safe transport, in case you
move or the amplifier ever requires shipping for repair. It is best if you place
it into an additional outer “over-carton” before shipment to minimize the
chance of theft in shipment.
Before you proceed, find the serial number which is located on the rear panel
of the unit and note it here for future reference.
S/N: __________________________________________
PLACING THE AMPLIFIER
• Keep the amplifier out of direct sunlight and away from windows that could
let in rain.
• The amplifier should be placed away from heat sources such as hot air ducts
or radiators.
• Do not place the amplifier directly on carpet that could interfere with airflow
into its bottom vent openings.
• If you place the amplifier on the floor, elevate it up off the carpet.
• If you stack your components, it is better to place the amplifier above or
alongside your other components. When driven hard, the amplifier creates
significant heat and can affect components stacked on top of it.
• If you place the amplifier inside a cabinet, allow ample ventilation and at
least 2" clearance on top and both sides.
• Very sensitive low-level sources might pick up some hum radiated from the
amplifier’s power supply.
MAKING CONNECTIONS
Before making any signal or speaker connection, make sure the amplifier is
turned OFF and unplugged.
When making connections, make sure there is no strain or tension on input
leads or speaker wires that could cause them to pull loose in the future.
Input Connections (

Connect the source component to the R and L Line Inputs.Make sure these are
consistent with R and L outputs from your preamplifier or source component.
