Digital Tuner with
Memory
Described as
"the first radical departure in tuner design in four decades".
Sanyo's Plus T55 tuner combines an electronically tuned front end and digitally
programmable quartz crystal reference oscillator to provide "superb"
audio performance. And thre's another unique benefit; it's impossible to
mistune a station. As long as the station's frequency appears in the bright
fluorescent digital display and the center tune indicator is lit, the receiver
is perfectly tuned at the exact point of minimum noise and distortion. Plus T55
has a passive four-pole LC filter that is double-tuned to reject not only the
19 kHz multiplex pilot tune, but also the 38 kHz multiplex subcarrier. Thus the
high frequency subcarrier cannot interact with the bias frequency of tape
decks. The band/mode selector lets you choose AM or either of two FM modes;
auto, with automatic switching to stereo
mode in the presence of a multiplex signal; and mono, which suppresses
stereo information in all signals, allowing noisy stereo signals to be heard
with improved quality.
