REAR PANEL CONNECTIONS
1.
LINE
IN.
The NAD 6125
is
intended
to
be connected
to
Ihe
Tape
REC
and
PLAY
(output and input)
jacks
at the
rear
of
any
conventional stereo amplifier. Insert the phono plugs at
one end of a stereo connecting cable fully into the LINE
IN
sockets on the
6t25.
At the other end of the
cable,
insert the
plugs
into the TAPE OUT or RECord jacks of the amplifier.
Use the color coding of the plugs to identify the
channels;
for
instance,
if one of
the
plugs at each end of the cable is red,
connect the red plug to the
R
(right channel) socket of both the
amplifier and the NAD 6125.
2.
LINE
OUT.
To
play
tapes, plug one end of a stereo
connecting cable into the NAD 6125's
LINE
OUT jacks, and
plug the other end into the TAPE IN, PLAY, or MONitor input
jacks of the amplifier. Make sure that each plug
is
inserted
fully into its socket, and observe the color coding of the plugs
to ensure that
the
stereo channels are connected
consistently.
3. AC
POWER
CORD.
Connect the AC power cord to a
convenient wall outlet or to an
"unswitched"
AC convenience
outlet at the rear of your
amplifier.
A note
on
fnstallatlon. The excellent performance of
the NAD 6125 stereo tape recorder depends on an array of
precisely machined
parts,
fine
bearings,
smoothly
polished
surfaces, sensitive detection of the weak magnetic
fields in
tape recordings, and amplification of very small signal
volt-
ages.
Consequently
the
recorder's performance can be
adversely aHected by external magnetic fields, electrical in-
terference, vibration,
heat,
mOisture, or chemical
fumes
.
Thus if it is placed directly on top
of
a power amplifier, the
6125 may pick up a low-frequency hum
from
the amplifier's
power transformer. If you wish to install it
next
to an amplifier
on the same
shelf,
place the 6125 on the
left
so that its cas-
sette compartment will be
located
away
from
the
amplifier.
The 6125 should not be placed on a loudspeaker or on a
television set
(a
source of strong magnetic fields as well as
vibration), nor in direct sunlight, nor very close
to
a steam
radiator, nor in a workshop where metal filings and chemicals
are
found
.
The
6125 will function best at temperatures that are
comfortable for
people,
and it can be stacked
or
shelved with
the remaining components in your stereo system.
If you are located near a powerful
television
or radio
transmitter (including a citizen's band or short-wave unit) you
may pick up interference, especially when playing
previously
recorded
tapes.
If
you encounter this type of radio-frequency
interference, you
may
succeed in reducing
it
by experimenting
with the location and orientation of
the
recorder.
If the
problem
perSists,
your dealer or a service shop may be able to add
approved circuit
modifications
or extra internal shielding.
Connecting two recorders.
Some stereo amplifiers
have
two sets of
tape
inpuVoutput jacks, with front-panel switching

to permit using either of two tape decks for
recording
or
playback and to permit copying tapes from one
to
the
other.
If your amplifier has only
one
set of connections for a
tape
recorder,
it is still possible to use two recorders with it. The
most convenient and flexible method is
to
purchase an exter-
nal sWitch-box (Tandy Radio Shack #42-2105 or equivalent),
which will provide inpuVoutput connections for up to
three
recorders
and allow copying among
them
.
The alternative
methods
described
below are less flexible, but they cost
less and yield equally good
recordi
ngs.
Copying.
Connect the "copying" recorder
(the
machine
on which the
new
copy will be recorded)
to the
amplifier's
TAPE recording/playback jacks as described
above.
Then
connect to the amplifier's AUXiliary input a cable from the Line
Output jacks of the "source" recorder (the machine containing
the tape that you want to copy), and switch the amplifier's
Input
Selector to
AUX.
If
an AUX input is not available, an alternative procedure
is to disconnect the cable from the amplifier's tape
RECord-
ing
output,
and connect the
"source
"
recorder's Line Output
directly
to the copying recorder's
Line
Input.
With this
con-
nection you must activate the copying recorder's
RECORD
function
in
order to monitor
the
playback output of the
source
machine.
Parallel
recording.
Two
recorders
can be wired in par-
allel
to
permit simultaneous recording on both. Obtain
two "V-
connector"
adapters,
each having two female phono sockets
and one male phono plug
(e.g.,
Tandy Radio Shack
#42-2436
or
equivalent).
Plug
one V-connector
inlo
the
Right
channel
Tape
RECording jack of the
amplifier,
and connect the Right
channel (red) plugs of
two
stereo cables to the V-connector's
two
sockets. Plug the
other V-connector
into
the Left channel
Tape REC
jack, and connect the left-channel plugs (usually
black) of the two stereo cables to the V-connector's
sockets.
Finally,
at the opposite end of the two stereo
cables,
connect
to
the
Line Input jacks of
the
two
recorders
.
This hookup allows you to
record
freely
on either ma-
chine, or simultaneously on both, but
not
to copy tapes
from
one
to
the
other.
NOTE:
This
method
of parallel connection works well for
recording, but
not
for
playback.
If
you use V-connectors to
combine
the
Line Output signals from two tape
decks,
each
machine's output will tend to short-circuit the other's, yielding
a
low
playback
level
and possibly higher distortion. Only one
tape deck's Line Output signals can be fed to the amplifier's
Tape
PLAY
input
jacks.
To hear the playback from the second recorder, connect
its Line
Output
to the amplifier's AUX
input.
But observe this
precaution
:
never switch
the
amplifier's Input Selector to AUX
while recording on the machine whose output is connected to
AUX; doing so would create a feedback oscillation that could
damage
your
loudspeakers.
