RADIO TUNER MARANTZ DIGITAL MONITORING ST-54 OTTIME CONDIZIONI

Descrizione

A digital synthesizer tuner that employs ultra-wideband ratio detection.

The receiving frequency is accurately selected by a four stage pure electron front end using a dual-gate MOS FET and a quartz PLL synthesizer.
The system is equipped with an anti-birdie filter to eliminate interference, and thorough measures such as eliminating beat interference are implemented.

In addition to being able to switch the IF stage between WIDE and NARROW fields and NARROW for weak electric fields, it is equipped with a "FINE tuning function" that finely adjusts in 10 kHz steps according to radio wave conditions.

The detector section, which converts RF signals into audio signals, uses ultra-wide-band ratio detection with superior differential gain characteristics.

A oxygen-free copper wire is used for wiring from the transformer to each stage in the power supply.

A total of 24 stations (16 FM stations and 8 AM stations) can be preset and stored in memory for channel selection, enabling one touch channel selection.
At the same time, FINE tuning and WIDE/NARROW of the IF stage can also be stored.
Also, it is equipped with a last station memory which stores the last station received.
