FM/AM tuner developed with the latest technological achievements.

It uses a blocked low-pass filter.
By providing a steep cut-off characteristic, the cause of noise is eliminated.

A newly developed coil unit sealed with epoxy resin is used for the FM multiplex circuit.
A monolithic IC with a double-differential switching circuit, which is the result of IC technology, is used in the coder section of stereo, enabling stable stereo reception regardless of high temperature and humidity.

The muting circuit block consists of a two stage IF component amplifier including one stage differential amplifier, and a DC switching circuit consisting of a narrow-band backward-tuning IFT and two transistors.
This blocks inter-station noise and prevents malfunctions in high-input regions.

Three 2-element ceramic filters are used in the intermediate frequency amplifier circuit, and an IF circuit consists of six stages including three differential amplifier circuits.

A 4-pole MOS FET is used for the FM front end.
A reverse AGC is also provided to prevent distortion when the input is too strong.

Equipped with two output terminals, variable and fixed.

The FM MPX OUT connector is provided to support discrete 4-ch broadcasting.

Equipped with AC outlet
