LUXMAN'S
NEW HIGH SENSITIVITY TUNER FRESH IN DESIGN PRESENTATION !
The T88V is designed as a matching tuner to
the L-80 series integrated amplifiers
with a common concept of being refined yet economical. It incorporates
all the useful features with a modern appearance.
The FM section consists of a 4-gang tuning capacitor and FET
RF amplifier circuits, inter-stage double tuning circuit, mixer
circuit, and special oscillator circuit of low distortion. Thus
result in excellent figures in such characteristics as high sensitivity,
signal over-load capability, various spurious responses and intermodulation
distortion. Therefore impecable quality reproduction of FM
broadcasting is possible over a wide range of signal strengths.
The
IF amplifier employs 2 pairs of linear ceramic filters together
with 2 transistors, and adoption of LC
double tuning circuit, wide band-width discriminator transformer.
A high gain IC makes it possible to obtain an improved phase relationship
as well as excellent distortion and separation.
In the MPX circuit the specially selected
PLL IC is used, which automatically
compensates for voltage and temperature drift etc. for many years
without the need for re-alignment, so ensures good separation and
low distortion. All above mentioned facts account for our meticulous
care paid to overall improvement of reproduced tonal quality. Also
a constant voltage supply circuit is provided at the power supply
section to offer high stability against fluctuation of power supply
voltage.
Annexed
accessories are FM high blend circuit, FM muting circuit, multi-path
detector and output level setter, etc. Among others the FM muting
circuit is of electronic operation by means of transistor logic
and FET analog audio muting, which
is controlled by signal strength and accuracy of tuning centre ensuring
a stable muting threshold irrespective of RF input strength, and
at the same time eliminates thump noises at the time of ON/OFF operation
of the muting switch.
The AM section is composed by high quality variable capacitor with
ceramic filter at the IF amplifier,
and therefore excellent selectivity and faithful reproduction of
AM programs.
