The SX-440
is the latest in stereo receivers, made strictly for those who care a lot about
stereo. It uses an FET in the FM front end to provide excellent selectivity,
and sensitivity as high as 2,5 µV (IHF). The AM tuner section is equipped for
ideal reception with a ferrite loop antenna. The audio-frequency output circuit
is all silicon transistorized and employs the SEPP-OTL system. Music power
output is at a dynamic 40 watts (IHF), with all this , the SX-440 will make a fine addition to your room and
you'll discover qualities of sound you never know existed.
FM Tuner
Section
When
choosing a good general-purpose stereo receiver careful inspection must first
be made of the FM section. The reliability of the front end section is vital
for perfect reproduction of FM monarual and stereo broadcasts. The FM front end
of the SX-440 is about the best you can get - a combination of an FET and a
three-gang variable capacitor. Even in areas where station crowding occurs the
SX-440 delivers clear, interference-free reception. The high sensitivity (2,5µV
) is indicative of the superior FM performance of this receiver.
FM Multiplex
Section
The advanced
circuity of the SX-440 includes an FM multiplex section, time switching type,
with automatic common, defeatable stereo functioning. Channel separation is
more than 38 dB (at 1khz). Easy to read front dial has a lamp to indicate FM
stereo performance.
AM Tuner
Section
The
superhoterodyne AM tuner has a receiving band of between 525 - 1605 kHz to
equal the range of Am broadcasts. Sensitivity is 8µV, so it doesn't require an
outdor antenna when in the vicinity of a station; the SX-440 has an adeguate
ferrite loop stick bar antenna to pick up most any AM broadcasts.
Audio
Section
The SEPP-OTL
system is used in the advanced audio output circuit. This gives it an output of
40 watts, perfect for home use and with powerful stereo separation.
Complete
Terminal Facilities
With the
SX-440 you can add a complete stereo
system from the selection of terminals provided. It combines ideally with tthe
best quality record players, stereo tape recorders and reverbration amplifiers,
with all terminals conveniently located, plus a set of auxiliary input
terminals. For tape deck versatility, a tape monitor circuit and tape
recording/playback jack to DIN standards are provided. You can ever connect two
separate loudspeaker systems through this practical receiver.
Elegant and
Unique Design
The midnight
black front panel is finished with special acrylic resin over the entire
surface, giving the SX-440 a sophisticated durable lustre. Power switch-on
brings out subdued illumination for crystal-clear readings. Take a look at the SX-440 and you'll agree it's the smartest
set ever.
