The CS-PCM tuner in which the MMB system D/A converter was carried.
The
MMB (Multiple Multi-Bit) system D/A converter which is proud of outstanding
engine performance and sound quality is carried.
This D/A converter carries
out the four-piece parallel drive of the 18-bit D/A converter selected
carefully, it is what aimed at the extensive engine-performance improvement, and
inputs the output of an oversampling digital filter into each converter parallel
8 times, and adds it in the state immediately after carrying out D/A conversion.
For this reason, regardless of the frequency and the level of a signal, the
engine performance is improved with all the frequency and all the signal levels.
The parallel drive of the MMB system is performing not simple parallel
connection but operation which every piece became independent of, respectively, and since full operation is carried out even when each D/A converter is
independent respectively, management of a phase serves as weight on high
frequency.
In T-110CS, coincidence of an ideal phase is realized by
selecting a converter element carefully and improving the approximation nature
of arrangement and a circuit pattern.
An 18-bit 8 time oversampling
digital filter is carried in the digital filter.
In the digital filter, the
inputted digital signal is made high to an integral multiple, it separates from
a music signal in the distance, the degree of a latter analog filter is lowered, and rotation of the phase is suppressed.
The digital B mode of CS-PCM
satellite broadcasting exceeds the level of CD by 48kHz of sampling frequencies, and a 16-bit straight line quantization system, and is proud of high-quality
sound almost equivalent to DAT.
Moreover, various programs can be enjoyed by
individual channel organization which cannot be heard by other media by special
broadcast classified by [ of 12 channels ] genre.
VITABI compound (system which compounds data under voice) LSI and PCM
compound LSI which were integrated more highly and raised the engine performance
are carried in the PCM tuner part.
The antenna adjustment switch and antenna input level
display function which can perform adjustment of an antenna simply are carried.
An antenna is adjusted so that this level display may be the greatest point,
and it will become renewable if it becomes more than a receivable level.
The 3rd GIC (Generalized Immitance Converter) Butterworth filter with
little phase rotation is adopted as an active filter.
This circuit has the
loose phase characteristic, and since a signal does not pass along an active
element by a passage region, the outstanding sound quality can be obtained in
it.
For connection with digital equipment, a toss link and two digital
output terminals of the same axle RCA are carried.
By connecting digital
recorders, such as DAT, digital recording is direct possible.
The analog
output terminal carries the XLR type connector for balance, and the RCA type
connector for disequilibrium.
The balance output has structure in the full
balance circuit by which floating was carried out from the ground. Moreover, it
is possible to remove the noise induced by the visitor noise in the middle of
transmission, and to prevent degradation of sound quality.
The scramble
decoder of a core tech system is built in.
The commercial antenna for CS broadcasting (the local oscillation frequency
of a converter is 11.2GHz) is supported.
