improperly affected thereby, providing the
requirements outlined above are adhered to.
In Your System
To ensure normal component life and safe
operation, this unit should only be operated
in an upright position. The special
non-marring elastomer feet provide
adequate spacing and stability only on a
smooth, hard surface, preferably on a
dedicated shelf or amp stand capable of
supporting 100 lbs. Check with the
manufacturer of your support system to be
sure it is rated to handle this weight.
The Reference 160S power transformer
generates a magnetic field that could, in
some installations, induce hum in sensitive
electronics such as turntables, phono
cartridges and phono stage preamplifiers.
For this reason, we recommend that any
such products and their interconnecting
cables be kept a minimum of 12” away from
the Reference 160S.
Vacuum Tube Life Expectancy
The vacuum tubes in your Reference 160S
have been burned in, tested and electrically
matched to provide the best performance
and reliability of your amplifier. That said,
vacuum tubes wear out with use and must
be periodically replaced. The KT150 output
tubes in the Reference 160S should have an
estimated life of approximately 3000 hours,
while the smaller 6H30 tubes should have a
life expectancy of approximately 4000
hours. These life expectancies are only
approximate. Please consult with your
dealer or Audio Research customer support
for more information. Warning: Tube
replacement shall be done by skilled or
service personnel, or qualified technician.
Ventilation Requirements
Installation
The Reference 160S employs forced air cooling using two ultra-quiet internal fans, located on
each side of the bottom cover about one third of the way back from the front of the chassis.
These fans draw cool air from under the unit, circulate the air internally to cool components,
and exhaust the heated air from grilles on the chassis top plate and transformer cover. It is very
important that cooling airflow to these fans not be impeded in any way by placing the unit on
carpet or a soft surface that might allow the Reference 160S to settle into the surface and
impede the airflow.
A minimum of 8 inches (21cm) clearance is required above the top of the amplifier. If the unit is
operated in an enclosure or equipment rack, keep in mind the above ventilation requirements
to make certain that adequate airflow above, to each side and to the rear is provided.
The ambient operating temperature should never exceed 86⁰F (30⁰C). Improper installation
will cause premature component and /or tube failure and will affect your warranty as well
as the service life of the unit. If you have any questions about correct installation,
pleaseconsult with your authorized Audio Research dealer or contact the factory at
service@audioresearch.com.
The forced air cooling of the Reference 160S will over time cause a buildup of internal dust
inside the unit that may impede proper cooling and result in reduced component life. Periodic
cleaning of the unit is strongly recommended. Refer to
Cleaning
, under the
Maintenance
section of this manual for instructions. It is normal for a vacuum tube amplifier to run quite
warm, and if used for prolonged periods, hot to the touch. All components within are, however,
operated at safe, conservative levels and will not be improperly affected thereby, providing the
requirements outlined above are adhered to.
