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
(
Figure 1, #5)
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.
