RECORD OUTPUT:
The BAL/SE tape outputs should be
connected to your recorder's “Record” or “Line” inputs.
These outputs provide a fixed-level two-channel signal
( L , R) to your recorder from whichever input is selected.
The non-variable output level will be the same as the out-
put of the selected source.
It is possible to dub or copy from one recorder to another
by connecting the output of the source recorder to an
unused set of stereo inputs (Aux 1, Aux 2). The signal
will then be routed to the Record Out connectors when
that input source is selected.
12V IN/OUT REMOTE START JACKS:
The +12V DC in-
put/output jacks provide the ability to remotely turn on and
off the preamp and other linked components such as power
amplifiers having similar capabilities.
Installation Instructions
While the Reference 5 does not dissipate an unusual
amount of heat, it is important that it be provided with
reasonable airflow to assure long, trouble-free operation.
In addition, the following installation guidelines will help
insure maximum sonic performance as well as reliable
service:
1.
Operate unit in upright and horizontal position, prefer-
ably on solid, non-metal shelving.
2.
Do not stack the preamp on top of a power amplifier: not
only could this cause overheating, but hum may be
introduced into the preamp from the proximity of the
amplifier's power transformer. Do not stack components
or other objects directly on top of the Reference 5.
3.
Do not place or operate your preamp on a soft or
irregular surface such as a rug. This will prevent proper
ventilation.
4.
Do not operate your preamp without the top and bottom
covers installed. These are required both for
safety as well as shielding from interference (except in
service operations by qualified personnel).
Operating Procedure
Start-Up:
1.
Secure all rear-panel connections between Reference 5,
power amplifier(s) and input sources.
2.
Plug three-prong power cord from rear of chassis into
grounded AC wall outlet. The Power switch defaults to
“off” when the unit is plugged into a power receptacle.
3.
Press power switch (either remote or front panel). “Mute”
will will flash in the display window for approximately
40 seconds, then cease flashing and remain in the
display. Press “Mute” to initiate operation.
4.
Select input source, then BAL or SE as necessary.
Shut-Down:
1.
Activate “Mute” function.
2.
Set Volume level to “0”.
3.
Turn off power amplifier(s).
4.
Press Power switch to “off ”.
5.
Turn off input sources.
Troubleshooting:
It is possible for a static discharge to temporarily disable
the microprocessor that allows the controls to function. If
this should occur, depress the “Mute” button, then turn
off the preamp and unplug the preamp from the A.C. recep-
tacle for 30 seconds. Reconnect the A.C. plug and turn the
preamp back on, along with other components. The
controls should resume normal operation. If the problem
persists, contact your dealer or Audio Research Customer
Service at 763-577-9700.
Servicing
Because of its careful design and exacting standards
of manufacture, your Reference 5 should require no routine
maintenance. The remote control's batteries (AAA) should
be replaced once a year.
C A U T I O N :
Your Reference 5 contains sufficient levels of
voltage and current to be lethal. Do not tamper with a
component or part inside the unit. Refer any needed
service to your authorized Audio Research dealer or other
qualified technician.
The vacuum tubes inside your Reference 5 are quality tubes
and with normal use should not need to be changed for
approximately 4,000 hours of use. Replacement tubes
should be of equivalent quality and are available from
Audio Research. Note that tube numbers (V1, V2 etc.)
match printed numbers next to tube sockets on circuit
board.
Should service be necessary, please contact your
Audio Research dealer, or Audio Research Customer Service
at (763) 577-9700.
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 solu-
tion 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 paint brush is effective in removing dust from
bevels, the recessed nameplate and other features of the
front panel.
