NOTES ON INSTALLATION
Your L 40 should be placed on a firm, level surface.
Avoid placing the unit in direct sunlight or near
sources of heat and damp.
Allow adequate ventilation. Do not place the unit on
a soft surface like a carpet. Do not put it in an
enclosed position such as a bookcase or cabinet that
may impede air-flow through the ventilation slots.
Switch the unit off before making any connections.
Use high quality RCA leads and connectors for
optimum performance and reliability. Ensure that
leads and connectors are not damaged in any way
and all connectors are firmly plugged. The RCA con-
nectors on your L 40 are colour coded red for Right
audio and white for Left audio.
For the best performance, use quality speaker
leads of 16 gauge thickness or more.
If the unit will not be used for some time, discon-
nect the plug from the AC socket.
Should water get into your L 40, shut off the power
to the unit and remove the plug from the AC socket.
Have the unit inspected by a qualified service techni-
cian before attempting to use it again.
Do not remove the cover, there are no user-ser-
viceable parts inside.
Use a dry soft cloth to clean the unit. If necessary,
lightly dampen the cloth with soapy water. Do not use
solutions containing benzol or other volatile agents.
REAR PANEL CONNECTIONS
1. SPEAKERS
Outputs for speakers with an impedance of 4 ohm
or more.
The 'RIGHT+' terminal should be connected to the
'+' terminal on your right-hand loudspeaker and the
'RIGHT-' connected to the loudspeaker's '-' terminal.
Connect to the left-hand speaker the terminals
marked 'LEFT+' and 'LEFT-' in the same way.
Heavy duty stranded wire or specialised speaker
cables to connect the loudspeakers to your L 40 is
recommended.
The high-current binding post terminals can be
used as a screw terminal for cables terminated within
spades or pin connectors, or for cables with bare wire
ends.
SPADE CONNECTORS
These should be slotted under the terminal's screw
bushings, which are then fully tightened. Ensure the
connectors are tightly secured and there is no danger
of bare metal from spade connectors touching the
back panel or another connectors, as this may cause
damage.
BARE WIRES AND PIN CONNECTORS
Bare wires and pin connectors should be inserted
into the hole in the shaft of the speaker terminals.
Unscrew the speaker terminal's plastic bushing until
the hole in the screw shaft is revealed. Insert the pin
or bare cable end into the hole and secure by tighten-
ing down the terminal's bushing.
Avoid any bare metal from speaker cables touching
the back panel or another connector. Ensure that
there is only 1/2" (1cm) of bare cable or pin and no
loose strands of speaker wire.
2. TAPE IN, OUT
Connections for analogue recording and playback
to an audio tape recorder of any type. Using a twin
RCA-to-RCA lead, connect the left and right output
(often labelled as “playback”, “Line out”, “Output”,
“Analogue Output”) of the tape machine to the TAPE
IN connectors of the L 40 for playback. Connect the
left and right input (often labelled as “Record”, “Line
in”, “Input”, “Analogue Input”) of the tape machine to
the TAPE OUT connectors of the L 40 for recording.
3. AUX INPUT
Input for additional line level input signals such as a
minidisc player. Use a twin RCA-to-RCA lead to con-
nect the auxiliary unit's left and right line level out-
puts (often labelled as “Line out”, “Output”, “Analogue
output”) to this input.
4. PRE OUT
Connections to an external power amplifier.
5. FM ANTENNA
A ribbon wire FM antenna is included and should
be connected to the FM ANTENNA connector at the
rear of the unit using the 'balun' adapter supplied.
The ribbon aerial should be mounted on a vertical
surface and placed so that it forms a 'T'.
Experiment with placement of the antenna to find
the position that gives the best signal strength and
lowest background noise.
An inadequate FM signal normally results in high
level of hiss, especially with stereo reception, and
interference from external electrical sources. The per-
formance of tuner section can be improved by using
an externally mounted FM antenna. A qualified aerial
installer will be able to advise and fit a recommended
aerial for your reception conditions.
6. NAD-LINK IN, OUT
The NAD-Link connectors are used to pass com-
mands from the remote control to and from other
units fitted with NAD-Link connectors. This allows
centralised control of a complete system or gives sys-
tem control from more than one room and remote
control operation of NAD units that are not remote
controllable on their own.
