Unpacking and Installation
Congratulations on Your Purchase!
Your new high fidelity Amplifier is designed to deliver maximum enjoyment and years of trouble free
service. Please take a few moments to read this manual thoroughly. It will explain the features and opera-
tion of your Amplifier and help insure a trouble free installation.
Please unpack your Amplifier carefully. We recommend that you save the carton and packing material.
They will be helpful if you ever need to move your unit and may be required if you ever need to return it
for service. Your Amplifier i is designed to be placed in a horizontal position and it is important to allow
at least two inches of space behind your unit for adequate ventilation and cabling convenience. To avoid
early damage, never place the unit near radiators, i in front of heating vents, in direct sun light, or in exces-
sively humid or dusty location.
Connect your complementary components as illustrated in the following section.

FOR YOUR SAFETY
To
ensure
safe
operation
the
three-pin
plug
supplied
must
be
inserted
only
into
a
standard
three-pin
pow-
er
point
which
is
effectively
earthed
through
the
normal
household
wiring.
Extension
cords
used
with
the
equipment
must
be
three-core
and
be
correctly
wired
to
provide
connection
to
earth.
Wrongly
wired
ex-
tension
cords
are
a
major
cause
of
fatalities.
The
fact
that
the
equipment
operates
satisfactorily
does
not
imply
that
the
power
point
is
earthed
and
that
the
installation
is
completely
safe.
For
your
safety,
if
in
any
doubt
about
the
effective
earthing
of
the

consult
a

Rear Panel Connections
1 SYSTEM GROUND TERMINAL
To reduce hum to a minimum, this terminal is used to interconnect the chassis or ground lead of the Turnta-
ble to this Amplifier. Attach the ground lead from your Turntable to this terminal. To further minimize
hum, it may be necessary to connect the GROUND terminal with a wire to the nearest water pipe which
goes directly to true ground.
2. PHONO INPUT JACKS
Input for turntable with a magnetic or variable-reluctance cartridge having-47,000 ohms of load impedance.
‘Connect shielded cables from your phono arm to the LEFT and RIGHT input jacks. To avoid loss of high
frequency response, it is recommended that these cables not exceed 6 feet in length.
NOTE: Do not place your turntable on a speaker enclosure. This will avoid howling caused by transmitting
of the speaker vibration to the turntable.
3. TUNER INPUT JACKS
Input for connection of your matching Tuner. You will have leads from the Tuner to connect to this Ampli-
fier. One lead will carry the LEFT channel information and should be connected to the LEFT TUNER
input. The other lead should be connected to the RIGHT TUNER input.
4. AUX INPUT JACKS
This extra stereo input is provided for any high level sources you may wish to connect to your Amplifier. An
additional compact disc player (CD), Video Disc Player, video tape recorder (VTR), a turntable with
ceramic cartridge or similar high level source can be plugged into this auxiliary input and selected by the
FUNCTION selector switch.
. 5. CD INPUT JACKS
Connect the output cables of the compact disc player to these jacks marked CD, matching the L cy) and
R (right).
6. TAPE PLAY JACKS
The output signal coming from your Tape Deck during playbacks is fed into these jacks and selected as a
listening source by depressing the TAPE MONITOR switch on the front panel (MONITOR ON) regardless -
of the position of FUNCTION selector.
These PLAY jacks may be connected to the line output of the audio processor like an additional graphic.
equalizer. .
7. TAPE REC JACKS
Signal from this jack is fed to the Rec of Tape Deck for recording purposes. Select the source to be recorded
with the FUNCTION selector on the front panel. Tone controls, loudness and volume settings have no
effect
on
the
signal
from
this
output
for
recording
except
the
FUNCTION
SELECTOR
switch.
For
monitoring this source while recording, depress the TAPE MONITOR switch and adjust VOLUME, etc. to.
_ the desired listening level.
These REC jacks may be used for the line input of the audio processor like an additional graphic equalizer.

REMOTE CONTROL OPERATION RANGE

DIGHLINK III System Remote Control Operation
You can remotely control not only AX-3030R but also Sherwood compatible components. The remote com-
mander mode No. RM-30 supplied with this amplifier is a common key operation type, for example there is
one play button on the commander and it can be used for playing cassette deck, CD player and CD changer
etc., SO we recommend you to read this section thoroughly. It will explain many features. —
