Connecting Speaker Systems The SEVEN connects up to three p<lirs of spe<lker systems. Any pair may be driven independently or a combination of two pairs may be dri\'cn . as selected by the Speaker Selector. Connect them to the recei\'er as instructed in the diagram on the left. taking care not to confuse the left and right channels and the plus and minus leads. Also. be very cCireflll not to short-circuit the pills nnd minus leads,

About the Speaker Impedance Each speaker system connected to ),our SE\,El\ must possess an impcdfll1cC of ., to 16 ohms. Should YOLI wish to dri\'c two pairs of speaker systems simultaneously (hy turn ing: the Speaker Selector to the ·.\ -'- If 0" '.-\ + C' position). each of them n","' have an impedance of H ohms or more.

2. Be Sllre not to let the antenna touch 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 keep the antenna as far from streets as possible to prevent picking up the noise gener­ated by automobiles.

If you should need long feeder cable to connect the antenna 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 matching 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.)

AM Antenna" Ferrite Bar A ntenna The highly sensitive AM ferrite har an tenna, pro· 'Aided on the 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_

O utdoor AM Antenna 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.

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.

Note: 1. If you wish to use a moving-coil (MC) type 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.

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 one 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 shielded cables bet ween the 'TAPE 1 (or 2) REG' pin jack terminals of the SEVEN and the recording input termimtls of your tape deck. 2. Connect another pair of such cables bet ween the recei"er's 'TA PE 1 (or 2) \ION' pin jack terminals and the tape deck's playback (monitor) output tenninals_ .

Note: 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_

Use the :!·CI I OUTPUT term inals as recordi ng outputs, and INPUT te rminals as playback inputs.

If U sing the DIN Socket In the rather unlikely event that your 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.

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 circui t.

4-CHANNEL STEREO SYSTEM

4.CHANNEL STEREO The sound we daily hear is a mixture of the sounds that reach Ollf ears straight from the sound source - be it a rnusical instrument, a jet, a Illa ll's mOllth

Of what ha\'e you-and the 'indirect sounds' that arrive at ollr cnrs only after they arc reflected of(

various su rfaces. such as the walls, ceiling and so forth . Four·channel recordings arc m£ldc using two microphones in the front of the concert hall and two in the rear (to simplify the explanation). The 'indirect sounds' with their compl icated wa\'cforms

arc mainly picked up by the two rear rnicrophones and reproduced out of the two rear speakers in a"", channel stereo sct-up for t{rcatly enhanced 'ambience'

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 REDUCTION ADAPTOR jacks on your

EVEN.

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 your 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 your tape deck(s) so connected, regard the NOISE REDUCTION ADAPTOR-OUT, -IN, -REC and ·~ION jacks on your 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.

With 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. REC ... 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.

SIMPLE MAINTENANCE HINTS

About the Place of Installation 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.

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.

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 by incomplete 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.

PM Connectors These arc the U·shaped jumper connectors connce· ting the 'PRE a 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.

Note: 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.

SIMPLE MAINTENANCE HINTS / ACCESSORIES

Quick-Acting Fuses 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. \¥hen a function Indicator is glowing, if no or dis­tortcd 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 thel11 , it is possible that one or more of the quick­

acting 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.

Should the Power Fuse Blow 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 fuse 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.

Rear-Panel AC Outlets 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 ITCHED' outlets h,I\'e a power capaci ty of 50 VA and 150 V A, 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 figures.

Grounding 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 entire system at once. If you hm'e connected an ex ternal A~l antenna to the recch'cr, it is advisable to grou nd it at the samc lime.
