FM/AM stereo tuner designed for easy enjoyment of AM stereo broadcast transmission

Equipped with AM stereo circuit.
In addition, it is equipped with an IF band switching circuit, so that the WIDE position with priority for sound quality can be switched under good reception conditions, and the NARROW position with priority for selectivity (forced mono interlock) can be switched when there is much noise, so that AM broadcasting can be enjoyed under the best conditions.

Equipped with a station memory function, up to 30 stations can be preset at random.
The character entry function allows you to enter the desired name (four letters of the alphabet) for each station.

It is equipped with a memory scan function, and you can receive preset broadcasting stations continuously for 5 seconds each.

Equipped with an RF attenuator, distortion can be improved by appropriately adjusting the input level when receiving strong FM radio waves.

The legs are equipped with a honeycomb insulator with excellent anti-vibration effect.

The rotary encoder enables quick channel selection.

Remote control terminal is mounted.

It is designed to save energy.
