2. Be Sllre no t to let the anten na tou ch electric
cables and other objects.
3 . Arrange the route of the feeder cable so as to
keep it as short as possible.
4. Try to kee p the antenna as far from streets
as possible to preven t picking up the noise generated by automobiles.
If you should need long feeder cable to connect the
ante nna or where the automobile traffic is hea,-y, it
is ad"isable to employ 750 coaxial cable. In this
case, howe\'er, it is necessary to connect a ma tching
transformer between the antenna and the coaxial
cable to match their impedances. Be su re to connect the cable to the Fi\ 1 750 tennimds. (If the
antenna itself has an impedance of 750_ no matching transformer is needed.)
Connecting Tape Decks
The SEVEN is pro"ided with two tape monitor circuits. One has pin jack terminals, while the other has
pin jack terminals, a DIN connector socket and
phone type jacks. If you arc connecting only one
tape deck, you are absolutely free to usc any lenninals which arc most convenicnt to YOll _ But if you
arc connecting two tape decks, be su re to connect
o ne of them to the first tape monitor circuit. and
the other to any terminals of the second tape
monitor circuit.
If U sing Pin Jacks
If you are usi ng the pin jack terminals to connect
you r tape deck, proceed as follows:
1. Connect a pair of s hielded cables bet ween the
'TAPE 1 (or 2) REG' pin jack terminals of the
SEVEN and the recording input termimtls of you r
tape deck.
2. Connect anot her pair of such cables bet wee n the
recei"er's ' TA PE 1 (or 2) \ION' pin jack terminals
and the tape deck's playback (monitor) output
tenninals _ .
AM Antenna"
Ferrite Bar A ntenna
The highly sensitive AM ferrite har an tenna, pro·
'Aided on th e rear of the recei,-er, is usually sufficicnt to obtain a quality reception of A~I stMions. To
usc, simply pull it out as illustrated_
No te: If you don't connect a 4-channel adaptor to
the 4-CHANNEL ADAPTOR terminals on the rear
panel, you Illel)' connect flnother tapc deck to them_
O utdoor AM A ntenna
Should the bar antenna fail to givc you a clear reception. however, connect a picce of pye wi re supplied to the Ai'vl-A terminal on the recci,-er's rear
panel and ex tend it outside a window or on the
roof. Still beller results can be obtained if you
ground thc recei,-cr.
Use the :!·CI I OUTPUT term inals as recordi ng
outputs, and INP UT te rminals as playback inputs.
If U sing the DIN Socket
In the rather unlikely event that you r tape deck is
equipped only with a DIN connector socket, plug
the DI 1 connector cable extending from it into the
5· pin DIN connector socket (marked TAPE-2 RECI
PLA Y) on the receiver's rear panel.
Connecting Turntables
As the SEVEN is equipped with two phono input
circu its, it is possible to employ two turntables or
two tonearms with magnetic cartridges.
Connect the output cables of the turntable to the
PHONO 1 or 2 input terminals. Be sure to keep
the left and right channel cables in proper order.
If Using Phone Jacks
Should your tape deck be equipped with cables with
phone type plugs, you may connect it to the phone
jacks on the receiver's front panel. The tape deck's
recording input plug should be inserted into the
upper 'TAPE REC' jack, and its playback output
plug into the lower 'PLAYBACK' jack.
Con necting a tape deck to the phone type jacks
automatically disables the pin jack terminals and
DIN connector socket of the second tape monitor
circuit.
No te:
1. If you wish to use a moving-coil (MC) ty pe
cartridge, be sure to employ either a step-up transformer or separate head amplifier between the
turntable and the SEVEN.
2. If you wish to use " ceramic or crystal type
cartridge, connect the outputs of the turntable to
the receiver's AUX input terminals.

NOISE REDUCTION SYSTEM
About Noise Reduction Systems
Tape hiss is the single greatest annoyance to tape
recording: enthusiasts. To eliminate this noise, se\'cr·
al noise reduction systems have been developed to
date.
The latest innovation in this area is ",.lIed the Dolby
system. which reduces tape hiss most effecti"e1y
without affecting the tone quality of the program
source sound. It ilwolvcs compressing low·lc\"cl
signals (where tape hiss is most annoying) during
recording and then expanding them during playback
in exactly the opposite manner.
The Dolby system often more than doubles the
stereo listening enjoyment. T'o take maximum ad·
"anlage of it, you only need couple a commercially
available Dolby :\oise Reduction Adaptor to your
SE\ ·E:\.
Connecting a N.R. Adaptor
Connect the Noise Reduction (N.R.) Adaptor to the
NOISE RED UCTION ADAPTOR jacks on your
EVEN.
W ith this in mind, make these connection. between
the SEVE:\ and the n.r. adaptor:
SE \ 'EN
N.R. Adaptor
OUT ... Input jacks of its recording circuit.
R EC ... Output jacks of its recording circuit.
MON .. . Input jacks of its playback circuit.
IN ..... .Output jacks of its playback circuit.
Operating a N.R. Adaptor
Operate the n.r. adaptor correctly according to the
instructions supplied by its manufacturer. Then it
is simply a maller of operating your tapc deck COf-
rectly for recording and playback and pushing the
·.R. ADAPTOR Switch on the SEVEN's front
panel.
Note: \Yhen you are recording via a two-circu it
type Dolby Noise Reduction Adaptor, changing its
mode switch from record to playback by mistake is
likely to cause a loud oscillating phenomenon. Be
very careful to avoid such mistake.
Such adaptor usually has four pairs of jacks-two
for connecting a tape deck, and two more for connecting an amplifier (in this case the SEVEN).
However, as you r SEVE is equipped with provisions for connecting up to two tape decks, it is
better to connect your tape deck(s) to the SEVEN
(refer to 'Connecting Tape Decks' on page 8).
With you r tape deck(s) so connected, regard the
NOISE REDUCTION ADAPTOR-OUT, -IN,
-REC and ·~ION jacks on you r SEVEN's rear
panel as equivalent to these terminals:
OUT ... Tape recording output jacks of an amplifier.
IN .. .. .. Tape playback input jacks of an amplifier.
REC .. . Recording input jacks of a tape deck.
MON ... Playback output jacks of a tape deck.

SIMPLE MAINTENANCE HINTS
A bout the Place of Installation
PM Connectors
The wooden cabinet of the SEVEN is designed so
that any heat radiated inside will cffecti\'e!y esc.ape
through it. Proper care should therefore be taken
of the dissipation of such heat if you wish to place
somcthin~ on top of the recei,·er or place it inside
a closed box. etc. Abo\'e all. ",'oid placing it where
it may he exposed to the direct sunlight.
These arc the U·shaped jumper connectors connce·
ting the 'PRE
T' (preamplifier output) jacks and
the ':\1A IN IN' (power amplifier input) jacks on the
rccci\'cr's real panel, and can be easily pulled out.
With these connectors unplugged, the preamplifier
and power amplifier sections arc separated and may
be independently uscd. For example, a different
power amplifier may be coupled to the 'PRE OUT'
jacks.
Separating the preamplifier and power amplifier
sections makes it possible to upgrade YOUT stereo
system further by adopting the 'electronic crossover
system: among other things.
a
W hen Connecting a Turntable, etc.
To connect a turntable. tape deck and so forth. it is
strongly recommended to use thick. shielded cables
with minimal distrihuted capacitance and to keep
them as short as possible.
To solder the pin plugs supplied as accessories onto
such shielded cables. refer to the illustration below.
No te :
1. Be sure to le""e the P1-.1 connectors firmly plugged in unless YOll want to separate the preamplifier
and power amplifier sections for some purpose.
2. Turn off the Power Switch without failure
he fore you plug in or Ollt the P ~ l connectors.
H um and H owling
Care must be taken nc\'cr to place a turntable on or
too nCar a speaker system, or the vibration of the
speaker system is transmitted and causes howling.
It is best to keep these components completely
separate but if this is impossible. place a thick
clishion between them .
Ilummillg is a phenomenon caused

or incorrect lurntablc·recch·cr connections. Should
this occur, check to see if all connections are COIl"!pletely made and if the connecting cables are suffi ciently thick. Be sure to connect the grounding
lead (or terminal) of the turntable to the GND
terminal of the SEVEN. It may suppress the hum
noise wich may otherwise occur.

SIMPLE MAINTENANCE HINTS / ACCESSORIES
Quick-Acting Fuses
Rear-Panel AC Outlets
Thc SEVEN's power transistors are protected by
four quick-acting fu ses. They are located on the
rear panel of the rerch·cr. concealed inside a plastics
cover.
Of the two AC outlets provided on thc rcar-panel,
the one marked 'SWITCHED' is con trolled by the
front -panel Power Switch. The othcr, markcd' NSWITCHED: is always 'live' and indcpendent of
the Power Switch. Thc voltage dcli"cred at these
outlets is the same as the power supply voltage
uscd .
Thc . ' \\-ITCHED' ' md ' NSW IT CHED' outlets
h,I\'e a power capaci ty of 50 VA and 150 VA, reo
specti\·ely. Before you connect any appliance to
them, be SUfe that it is adjusted for use at the same
power supply voltagc, and that its power consumption is not beyond these figu res.
\ ¥hen a function Indicator is glowi ng, if no or dis-
tortcd sou nd comes out of onc or both of the speaker systems, examine their connections and your
operating procedure once. If nothing is wrong with
th el11 , it is possible that one or more of the quickacting fuses ha"e hlown. Should this happen, disconncct the power cord from thc wall AC outlet immediately, then remo\"c the metal co\'er by loosening the two screws securing it to the rear panel, and
chcck the four quick-acting fuses. If you find any
of them blown. disco\'cr and eliminate the cause of
the blowout, and replace it with a new 4-ampcrc
quick-acting fuse supplicd. Probablc causes of the
blowout include excessively large input signals and
a short-circui t at the speaker terminals.
Grounding
Should the Power Fuse Blow
Any noise I,;ckcd up by thc connccting cables can be
cffecti"ely groundcd by connccting a piece of PVC
(pol)'\"inyl chloride) or enameled wire to the 'GND'
terminal on the SEVEN's rear panel, attaching a
small copper plate or carbon rod to the other end
and burying it dec I' underground . Thc grounding
Icads of other cquipmcnt in your stereo system may
be connected to the same terminal to ground the
e ntire system at once.
If you hm'e connected an ex ternal A~l antenna to
the recch'c r, it is advisable to grou nd it at the samc
lime.
If no Function Indicator should glow and thc rccei"cr
simply remains dcad C\'cn after you have turned on
its Power Switch, it is possible that its power fu se
has blown. If this happens, disconnect the power
cord from the wall AC outlet at once and examine
the power fusc on the receiver's rear pancl. If you
find it blown, replacc it with a new glass-tubed fuse
of the rated capacity (5-ampere for 100 to 127 volts,
:J-ampere for 220 to 250 ,·ol ts). Nevcr use a fuse of
a different capacity or a piece of wirc, even as a
stop-gap measure, or serious dangcr could result.

GENERAL TROUBLESHOOTING CHART
If the receiver is otherwise operating satisfactory, the
more common (causes of trouble ma y generally be a ttributed to the following:
1. Incor rec t conn ections or loose terminal cont~tc l s . Check
the speakers. turntable. tape deck. antenna and power
cord.
2. Improper operati on . Before operating any audio com-
ponent, be sure to read its manufacture's instructions.
3 . Improper location of audio components. The proper
positioning of compon ents, such as speakers and turntable,
is essential to maximum stereo enjoyment.
4. Defective audio components.
The following arc some other common causes of mal·
function and what to do about th em .

times or in certain
area.
• Discharge or oscillation
caused bv e lec trical appli·
ances, such as fluorescent
lamp. TV set. D.C . motor
rectifier or oscillator.
.. Attach noise limiter to elec trical appliance producing noise. or attach it
to receiver's power souce.
• Install outdoor antenna and ground
receiver to raise SN ratio.
.. Rcverse power cord plug/receptacle
connections.
.. If noi se occurs at certain frequency,
attach wave trap to input.
.. Keep receiver at proper distance from
other electrical appliances.
• Natural phenomena, such as

ote: FM reception is affected con ~i derably by
transmission condit ions of station. such as power
and antenna efficiency . As a result, you may
receive onc s tation quite we ll while recei \'ing
another station poorly.
.. Install antenna (supplied ) ror maxi·
mum signal strength .
• If this does not prove effective. use
exclus i\'e FM outdoor antenna . If
using TV antenna for both TV and
FM with divider. make sure TV
reception is not affected.
.. Excessive ly long lead· in wire of an·
