The Toshiba 7150 locks into the center of any station's assigned broadcast frequency and eliminates drift.
A few yearas
ago, Toshiba introduced and marketed the first fully electronic
digital-synthesized tuner. Now Toshiba has another first. We've built a
digital-synthesized tuner into a high-powered, low-distortion FM/AM receiver;
the Toshiba 7150 with Synthetune™
Synthetune
is a function that provides tuning so accurate even a center tuning meter is
unnecessary.
Drift is eliminated.
Drift is eliminated.
The 7150's
FM tuner section also contains flat group delay IF circuitry. And a quartz
crystal oscillator, which automatically locks into the center of any station's
assigned broadcast frequency - as precisely as the station's own transmitter.
Tune the
7150 just by pushing the auto-scan button. It scans the full range of the AM or FM band, stopping precisely at each
listenable station. Bright green LED numerals instantly display all frequencies
as they are tuned. Of course, there's more to the 7150 than Synthetune. It also
has separate transformers for class A and class B amplifier sections. The
toroidal transformer for class B amplification has separate left and right
power supplies.
It also has
Dolby FM and an air check switch for accurate tape recording. Furthermore the
7150 delivers a minimum of 150 watts per channel into 8 ohms, 20 Hz to 20,000
Hz , with no more than 0,05% Total Harmonic Distortion. And the restof the
specs are just as impressive.
