Ultimate
High-Fidelity Stereo Component Model T-110 FM/FM-MPX Tuner
New compact tuner
for FM only reception. An epoch-making new approach to styling departs from the
conventional concept of tuners which have normally treated product dimensions
to equal those of the matching amplifier.
Unlike conventional
tuners, the entire dial plate is designed as a unity with tuning and signal
strength meter - in other words tha dial scale isplaced in the meters.
The dial scale and
letters are of etched aluminium foil. An additional feature is in the special
tuning pointer which blinks at interstation settings and lights up when
stations are tuned.
Features of
circuitry
Included in the
front end is a 5 gang variable capacitor, a low distortion oscillator and MOS
FETs in the RF amp and mixer stages, which ensures an amazing characteristic
exceeding 100 dB in all kinds of rejection ratio such as image, spurious
response and IF.
To obtain good
selectivity and low distortion at the same time, the IF stage employs 2 sets of
4-complement linear phase LC block filter and a cerammic filter.
The combination of
LC block filter and a ceramic filter compensates mutual delay time and helps
lower distortion and increases selectivity. Specifically, the distortion figure
is below 0,08% 9both streo and monaural) -
unprecedented in tuners in this price bracket.
Also, selectivity is
excellent in the event that both the desired signals and interfering one are
stereo.
Other, IF stages are
composed of ICs of large scale integration.
The MPX circuit uses
PLL ICs .
A special PLL IC is
provided which yields low distortion equivalent to that of discrete circuit
adoped in the T300.
An IC for pre amp is
used in the last stage of the audio amp to achieve the lowest possible
distortion.
Additional features
are high output multi-path detector circuit, 4-CH output terminal and
attenuator circuit for RF input.
In addition, to
remove the unpleasant "thump" noise at the time of on/off operation
of power switch, time delay is provided until the circuit is put into
operation.
