Commentary
FM/AM stereo tuner that also supports AM stereo.
Equipped with AM stereo demodulation circuit, it is compatible with AM stereo.
The LC tuning circuit and 4-element ceramic filter improve both the bandwidth required for AM stereo and the ability to eliminate adjacent channel interference.
Equipped with a low-impedance output circuit of 500 Ω or less, it enables high-density signal transmission to the amplifier, and realizes excellent sound quality with high-frequency attenuation characteristics.
We also prevent troubles in matching with amplifiers and transmission caused by external noise.
Equipped with 30-station random preset function.
Wireless remote control is included.
This remote control allows you to control Up down frequencies, channel (preset) up/down, band switching, auto / manual switching (auto-stereo, auto-tuning, FM muting, manual tuning), preset scanning, power on / standby, and more.
In addition to the black model TU-280, there was a gold model TU-280G with side wood.
