SAFETY PRECAUTIONS
WARNING: to prevent fire or shock hazard, do not expose this unit to rain or moisture. Care should
be taken to prevent objects or liquid from entering the enclosure. Never handle the power cord with
wet hands.
• The lightning flash with arrowhead within a triangle is intended to alert the user of the presence of
uninsulated "dangerous voltage" within the product's enclosure that may constitute a risk of electric
shock to you.
• The exclamation point within a triangle is intended to alert the user of the presence of important
operating and maintenance (servicing) instructions in the literature accompanying the unit.
• Caution: To prevent the risk of electric shock, do not remove cover. No user-serviceable parts inside.
Refer servicing to qualified service personnel.
• If an outdoor antenna is installed, be sure it is grounded to provide some protection against voltage
surges and built up static charges. Keep outdoor antennas away from power lines.
• Unplug the preamplifier from the AC outlet when plugging in or unplugging cables, when left unused
for an extended period of time, when moving the preamplifier, or when you suspect lightning in your
area.
• Prevent damage to the power cord. Replace the power cord if it becomes damaged in any way.
Always grasp the plug on the power cord when plugging or unplugging the preamplifier from the AC
outlet.
• Your system may produce sound levels capable of causing permanent hearing loss. Do not operate
for extended periods of time at high volume levels.
• Protect the preamplifier from impact and place the preamplifier on a level surface.
• The preamplifier is equipped with raised feet to provide ventilation, reduce acoustic feedback, and
protect against scratching the surface the unit is resting on. B& K advises against removing the feet.
• Do not stack anything on top of the preamplifier (processor, source, etc.) Leave a minimum of 3"
clearance from the top of the preamplifier to the next shelf (or component).
• The preamplifier should be located away from sources sensitive to heat.
• Do not perform any internal modifications to the preamplifier.
• Always connect the preamplifier's power cord to a dedicated AC outlet for normal operation.
• If young children are present, adult supervision should be provided until the children are capable of
following all rules for safe operation.
• Mistaking CONTROL OUTPUT or IR INPUT connectors for audio/video inputs or outputs may
damage your preamplifier or other components.
•System impedance SHOULD NOT fall below the nominal impedance of the amplifier stage, i.e two
8Ω speakers in parallel = 4Ω (system impedance). Minimum stability refers to the periodic audio
passages that demand large amounts of current at which time the output impedance drops.
The preamplifier should be serviced by qualified personnel when:
A. The preamplifier is not functioning properly.
B. Objects have entered the chassis.
C. The preamplifier was exposed to rain or any other type of moisture.
D. The preamplifier was dropped, or the chassis is damaged.
