IPIONEER SOME UNIQUE FEATURES: aFM front - end employing a field effect transistor to hear more stations more clearly olntegrated circuit (lC) employed in FM tuner assures outstanding capture ratio with high reliability. oMultiplex circuitry (MPX) for maximum channel separation oUnique muting circuit permits the easiest tuning control oHigh performance single ended push-pull (SEPP) output stage eliminates audio transformers and provides large output with true frequency fidelity OFull complement of inputs and outputs oElectronic switch fully protects precious power transistors the By the use of FET (field effect transistor) in the FM radio frequency amplifier stage, design of nearly perfect FlVl front-end was achieved-free from cross modulation, free from drift, with better sensitivity, lower inherent noise, and high spurious rejection ratio. ln the FM intermediate frequency amplifier stage, integrated circuits are employed, resulting in an entirely different outstanding performance from that of lFstages hitherto designed, especially in the limiter characteristic and the capture ratio. The accurate electronic switching circuitry is employed in the FM multiplex demodulator, insuring maximum separation with excellent tonal quality. The muting circuit provided in the FlVl tuner completely eliminates the FM inter station noise whrch has hitherto been annoying the user in tuning. The power amplif ier employs the high-performance single ended push- pull circuitry in the output stage and the push,pull complementary circuitry in the driver stage, completely eliminating the distortion rnherent transformers from the audio stage. Tripple diffused mesa transistors are adopted as the power transistors in the output stage for full-fidelity frequency response with large audio output power and least harmonic distortion. The inputs and outputs pr,ovided in the receiver include two pairs of pHONO MAG inputs. When two turntables are connected to these inputs, the user is able to switch from one turntable to the other any time at will. Also, two pairs of ioudspeaker outputs are included for switching between, or for per- mitting the simultaneous use of, two loudspeakers. The electronic switchrng circuitry employed in the power supply completely protects expensive power transistors even when the loudspeaker leads are shorted while the receiver un,L is in use INSTALLATION As this receiver is sully transistorized, desirable places to install it are as follows: OPlaces airy and free from humidity and dust. Avoid insta ling on close, low-ceiling shelves. OPlaces not directly exposed to the sun ray. OPlaces not close to heat-emitting objects such as heaters and stoves. LINE VOLTAGE SELECTION AND FUSE Switching Line Voltage Setting and Fuse In order to remove the fuse, turn the fuse cap located on the line voltage selector switch in the direction indicated by an arrow. Then remove the fuse plug from the unit. Put the fuse plug back so that the proper line voltage marktng can be seen thru the cut on the edge of the plug. Whenever the set position of the selector swttch is changed, check the rating of the fuse. A 1.5-ampere fuse is to be used for either 220\l or 24OV operation and a 3-ampere fuse for any of 110V, 117V, or 130V operation. lf the rating of the fuse is proper, install the fuse on ihe fuse cap. OPlaces where there is as little vibration as possible and where the surface is level. The optimum stereophonic listening position is across the room from the speakers, sornewhere close to the midpoini between the right and leit speaker systems.
