Commentary
FM/AM tuner equipped with Marantz traditional gyro touch tuning.
The traditional Marantz gyro-touch tuning using oilless metal for the flywheel bearing is smooth with less backlash problems, enabling reliable tuning and fine adjustment.
The front-end uses a dual-gate MOS FET to ensure a wide dynamic range and provide excellent performance characteristics that are resistant to overloading.
It is equipped with an original parametric muting, and there is no noise when detuning. It is also equipped with two types of terminals, fixed output and variable output, which are convenient for air check.
For optimum AM reception, a folded ferrite rod antenna for horizontal all fingers direction is mounted.
Cabinet is sold separately.
