Ultimate
High Fidelity Stereo Component
AM/FM Stereo
Receiver Luxman Model R-1050
A brand New
reciver with LUX's impeccable breeding and modern styling.
Pre-amp
Section
A rotary
switch makes it possible to select FM, AM, Auxiliary, or either of two phono
inputs. The equalizer stage is composed of a two stage direct coupled amp with
PNP and NPN transistors, which ensures excellent linearity and adeguate phono
overload protection.
Two sets
each of tape input and output allow duplication from one tape recorder to the
other or vice versa and instantaneous monitoring from either input. This is an
extremely useful and unusual feature.
Lux's well
known NF type tone controls are provided for treble and bass, and low and high
cut filters are also included. A loudness switch is employed to boost both
treble and bas at low volume levels.
Power Amp
Section
Direct
coupled DC output amp circuitry utilizing dual rail power supply ensures the
best possible bass, the smallest distortion, and very low noise.
The output
stage with almost mandatiry fully complementary configuration makes it possible
to suppress distortion to an almost immeasurable level of typically 0,05%.
A time delay
muting circuit is provided to remove unwanted switch-on thumps and this
simultaneously plays the role of speaker protector.
Very useful
and equally eye-catching LED peak indicators make it possible to read the
output power level instantaneously.
FM Section
A high class
4-gang tuning capacitor in the front end offers an excellent 1,8 µV
sensitivity, and good overload and spurious characteristics are realized in
combination with the dual gate MOS FET.
Linear phase ceramic and block filters guarantee good band pass
response. These filters are excellent in group delay time characteristics and
sharp skirt selectivity, and a quadrature IC and distortion free discriminstor
transformer ensures good limiting and low distortion.
For stable
and excellent distortion as well as good separation and S/N ratio, a select PLL
MPX IC is adopted, and also an exclusive LC low-pass filter is used to suppres
carrier leakage. Moreover a constant voltage supply circuit is provided to
ensure stable function of aech section.
Dolbylized
FM can be received with the insertion of
an additional Dolby circuit board. Unique LED peak Indicators permit
instantaneous reading of peak power output.
AM Section
For high
grade reception of AM broadcasting as well, meticulous care is paid utilizing
modern technology, which can be seen in strong AGC, a ceramic filter of good
selectivity and a low distortion detector.
