Halaman CetakThe switched MP3 dedicated input
(3.5mm jack socket) allows quick con-
nection to your iPod™ (or similar
device with an analogue output) using
a suitable interlink cable.
When the 6.4mm or 3.5mm head-
phone / earphone sockets are used,
other signal outputs are automatically
switched off.
Remote control.
The remote control allows you to
adjust the volume, mute the sound,
dim or turn off the visual display; and
change from one RCA Phono (or MP3)
input source to another. Point the
remote at the facia panel when using.
It will work up to 10Mtrs. from the
pre-amplifier up to a 30 degree angle
either side of front.
The remote will also operate the
AT3000 CD Player but no other equip-
ment. If you are also using the
ASTINtrew CD Player, the mute func-
tion will mute both.
Refer to the illustration on page 6.
In the unlikely event of the pre-amplifi-
er failing to work properly when first
switched on please refer to trou-
bleshooting in section 8.
7. Valve and fuse replace-
ment.
The valves supplied and fitted in this
pre-amplifier have been selected to
offer a high quality neutral sound. If
you wish to experiment with alternative
manufacturers' valves after the war-
rantee period has expired, ensure that
the factory fitted valves are replaced
with ECC82 (12AU7) types only.
Other valve types may damage the
pre-amplifier and also void the warran-
tee.
Replacing or substituting the valves
can be carried out by your dealer or
distributor, or you can replace them
yourself, with care. If you attempt to
replace the valves yourself, the follow-
ing instructions must be adhered to
exactly.
Note: Dangerously high voltages
are present inside the unit when
powered from the mains
that can KILL.
NEVER open the pre-amplifier when
attached to the mains supply.
A. Disconnect the pre-amplifier from
all equipment and the mains supply.
Place on a table or work bench
with plenty of space around.
Note: Wait at least 1 hour before
opening the top cover to allow the
valves time to cool down and the
capacitors to dissipate
their charge.
B. Undo the 10 x M3 Alan screws
holding the top plate in position
with the Alan key supplied. Put the
screws somewhere safe.
