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. - 8 Not For Sale OPERATIONS FM Reception 3.

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 reprodu ced out of the two r ear speakers in a"", channel stereo sc t-up for t{rca tl y enhanced 'ambience' effects. . Th e result is almost as if the oriJ.!inal li\'c pedorll1 ~mcc were f e-played r ight in YOUf own rool11. This new approach can now be yours simply by adding certain equipment-mainly. a ansui-lchannel rear amplifier and a second pair of speaker syste ms-to your :!-chan ncl stereo system .

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 ...

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 by incomplete ELECTRONIC CROSSOVER DIVIDER 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. - 12 - Not For Sale 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. / .)/,/ "/;/ '//);/ , //'/'/ "////////1/ / 1///////////,;; ATI ACH COPPER PLATE OR CARBON ROD.
