Audio Research LS26 Owner's Manual - Model Ls26
Tape Recording Procedure
When using the LS26 as a control center for recording, the
program source to be recorded must be connected to one of
the six inputs controlled by the Input selector switch or to
the Processor input. This routes the selected program to the
Record output.
Note: If the Processor input is activated by selecting the
“Processor” switch position, all other inputs will be deacti-
vated. When recording from the Processor input to the
Record out of the LS26, the level of the recording will be
dependent on the level setting of the processor.
If you own a three-head tape deck, and wish to monitor the
actual tape while making a recording (for a true “A-B” com-
parison of signals before and after recording), connect the
tape deck output to the Monitor input.
It is also possible to dub from one tape deck to another.
Simply connect the output from one tape deck to an un-
used set of inputs controlled by the Input selector (Tuner,
Phono, C D, etc.) on the LS26. This signal will then
be routed to the second tape deck through the Record
output when the appropriate input is selected on the Input
selector.
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 60 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 LS26 should require no routine main-
tenance. The remote control's batteries (AAA) should be
replaced once a year.
C A U T I O N : Your LS26 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 LS26 are quality 6H30 dual
triode tubes and with normal use should not need to
be changed for approximately 4,000 hours of use. Replace-
ment tubes should be of equivalent quality and are
available from Audio Research. Note that tube numbers
(V1 and V2) 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.
