The SX-300T
Solid-State 40W Stereo Receiver is a precision made instrument the end result
of meticulous research, design and engineering. Hand-made by craftsmen under
strict quality control standards to insure you of a personal pride of
ownership. All transistorized circuits from the frontend through outputs.
Function and performance are superior to any other receiver in its price range.
An optional walnut wood cabinet (CA-20) is available.
Features of
SX-300T
A unit type
employing an abundant numbar of printed circuit boards. FM front-end, multiplex
circuit, AM tuner, FM-IF unit, equalizer, tone control, main amplifier, etc.,
All major circuits are of a complete unit type employing precision printed
circuit boards. Troubles due to wiring have been virtually eliminated assuring
many years of annoyance fre operation.
Transistorized
front end.
Transistorization
of FM front-end, which is technically very difficult, has been successfully
achieved. The circuit system is of a 3 transistor, separate excitation front
end, and a multiplex tuning 4-IF stage, of which 2 stages are limiters with
AGC. An excellent sensitivity of 3 µV as per IHF specifications and an image ratio of 55 dB (in 82 MHz). A
wide band ratio detection method is employed.
Automatic
switching mechanism with multiplex circuit.
Separation
of the multiplex circuit is more than 20 dB over a wide range of 40 - 8000 Hz.
In addition, an FM mono/stereo automatic switching mechanism, a switching unit
employing Schmidt circuit is provided. This ensures unfailing and stable
operations. Owing an FM stereo broadcast a separate mono - stereo indicating
lamp lights to show it.
Tuning
indicator to assure precise tuning.
Accurate and
precise tuning is imperative for a noise free clear tone reception of a
broadcast. SX-300T is equipped with a high-sensitivity tuning meter for tuning
indication.
Low
Frequency Output Circuit
The main amplifier adopts a complementary circuit which does not use an
input transformer. The OTL system of single ended push pull (SEPP) gives a rich
sound reproduction in a wide band of 20 Hz to 20,000 Hz . Other excellent
features include: the output power of 40W in music power, (distortion factor is
less than 1%), effective output of 15W x 2 (distortion factor is less than 1%),
damping factor of 25 (1 kHz/8 Ω
)
Newly
Designed Speaker Connection Terminal
A screw
terminal of conventional type is provided as an output terminal for speaker.
Since the terminal itself is designed to serves as a plug, it assures a proper
and secure connection.
Various
auxiliary equippment that enable you to enjoy magics in the sound Loudness
contour assures a rea life sound even as a low level AFC ON-Off switch, jack
for stereo headphone, input/output terminals for recording and reproduction
with tape recorder and, a connector jack by DIN specifications are provided to
make this equipment more versatile.
