B&K 200.2 S2 User Manual

••    The lightning flash with arrowhead, within an equilateral 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 an equilateral 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.
••    Unplug the amplifier from the AC outlet when plugging in or unplugging cables, when left unused for

an extended period of time, moving the amplifier, or when you suspect lightning in your area.
••    Prevent damage to the power cord. Do not bend, pull, place objects on, alter, etc. Replace the

power cord if it becomes damaged. Always grasp the plug on the power cord when plugging in or
unplugging the amplifier 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.
••    Make sure the amplifier is placed on a level surface.
••    The amplifier is equipped with raised feet to provide ventilation, reduce acoustic feedback, and pro-

vide protection against scratching the surface the unit is resting on. We advise against removing or 
altering feet.
••    Do not stack anything on top of the amplifier (processor, source, etc.) Leave a minimum of 3"

clearance from the top of the amplifier to the next shelf (or component) to insure proper ventilation.
••    The amplifier should be located away from other sources that may be sensitive to heat.
••    Do not perform any internal modifications to the amplifier.
••    Always connect the amplifier's power cord to an unswitched, 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 CONTROL INPUT connectors for audio/video inputs or outputs

may damage your amplifier or other components.
••    Damage can occur to your speakers if the power rating of each individual driver is exceeded by the 

amplifier. Ensure that all the drivers in your system are capable of handling not only the average 
power being delivered by the amplifiers, but also the peak power that is likely to be generated during 
strong passages.
••    Reference 200.1 S2 or Reference 200.2 S2 amplifiers can have drivers connected in parallel to

each amp channel.  System impedance SHOULD NOT fall below the nominal impedance of the
amplifier, i.e two 8

Ω 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 amplifier should be serviced by qualified personnel when:
A.

The amplifier is not functioning properly.

B.

Objects have entered the chassis.

C.

The amplifier was exposed to rain or other type of moisture. 

D.

The amplifier was dropped, or the chassis is damaged.
