Audio Dynamics T-1
¥ 40,000 (around the mid-1980s?)
Commentary
FM/AM tuner of the Eurostyle component series.
Quartz synthesizer system is adopted.
Ten FM/AM stations can be preset / stored.
Also, memory can be retained even when power is turned off by battery backup method.
The channel selection can be done quickly with the 3-speed tuning button.
Equipped with Schutz noise reduction.
This circuit effectively cancels the noise according to the FM signal strength and the high-frequency component level, and realizes clearer stereo reception.
