Warnings
To prevent fire or shock hazard, do not
expose your Reference Phono 3
to rain or moisture.
Do not place objects containing
water on top of this unit.
This unit contains voltages which can cause
serious injury or death. Do not operate
with covers removed. Refer servicing
to your authorized Audio Research
dealer or other qualified personnel.
The detachable power cord on your
Reference Phono 3 is equipped with a heavy
gauge, 3-conductor (where applicable)
cable and a standard three-prong
grounding plug. For absolute protection,
do not defeat the ground power plug.
This provides power line grounding of
the Reference Phono 3 chassis to provide
absolute protection from electrical shock.
The appliance coupler (a.c. power connector)
at the rear of this unit must be accessible
for emergency power disconnect.
The power button on the front of this
unit, when off, does
not
disconnect
all power from this unit. This unit
is in sleep mode when not on.
For continued protection against fire hazard,
replace the fuse only with the same type
and rating as specified at the fuse holder
(see page 19 for fuse information).
This unit is RoHS compliant.
The Reference Phono 3 has automatic
muting to help protect system components
in the event of low line voltage. When
sensing low line voltage, the preamp
displays ‘Low Line’ and automatically goes
into ‘Mute’. This condition will persist until
the line voltage returns to a safe operating
level; please note the unit will remain
in ‘Mute’ even after ‘Low Line’ no longer
appears.
Note that automatic muting is only
designed to protect against power line
interruptions or severe voltage drop. It
will not mute in the event of subsonic
transmissions from a faulty input source,
amplifier failure or speaker malfunction.
A note about packaging...
Save all packaging in a dry place away
from fire hazard. Your Reference Phono
3 preamplifier is a precision electronic
instrument and should be properly
cartoned any time shipment is made. You
may not have occasion to return your unit
to the factory for service, but if that should
prove necessary, or other occasion requiring
shipment occurs, the original packaging
will protect your Reference Phono 3
from unnecessary damage or delay.
