off amplifier and check line voltage.
6. Your amplifier should now operate
satisfactorily. It may be played
immediately, although best sonic
performance will in most cases not be
achieved for an hour or so (see
INSTALLATION for further details.)
Start-Up Following ‘Protect’
Shutdown:
The DS450M amplifier uses a
sophisticated, non-fused sensing circuit
to protect the amplifier from DC at the
input, from thermal overload, and from
shorting conditions at the output (e.g.
defective speaker leads, etc.). This
circuit also helps prevent damage to
your loudspeakers.
When the amplifier senses a fault
condition in either channel from
excessive DC or excessive output
current, it will automatically shut off left
or right outputs from the amplifier.
Amplifier will automatically return to
normal operation when fault is removed.
If the amplifier fails to resume normal
operation after removal of a fault
condition, contact your authorized
dealer for further assistance.
Servicing
Because of its careful design and
exacting standards of manufacture,
your DS450M amplifier should normally
require only minimal service to maintain
its high level of performance.
CAUTION: The DS450M
amplifier contains sufficient
levels of voltage and
current to be
lethal . Do not
tamper with a component or part inside
the unit. Even with the power turned off,
a charge remains in the energy storage
capacitors for some time. Refer any
needed service to your authorized
Audio Research dealer or other qualified
technician.
Additional questions regarding the
operation, maintenance or servicing of
your amplifier may be referred to the
Customer Service Department of Audio
Research Corporation at 763.577.9700

from Audio Research or an authorized
dealer, be sure to identify the serial
number on your amplifier.
Cleaning
To maintain the new appearance of this
unit, occasionally wipe the front panel
and top cover with a soft, damp (not
wet) cloth to remove dust. A mild, non-
alkaline soap solution or dilute isopropyl
alcohol may be used to remove
fingerprints or similar smudges. Cleaners
containing abrasives should
not be used
as they will damage the anodized finish
of the front panel. A small, soft
paintbrush is effective in removing dust
from bevels, the recessed nameplate
and other features of the front panel.
