Noise reduction unit equipped with dbx system.
In order to ensure that the dynamic range of music over 100 dB is recorded faithfully to tape, dbx records the level at 1 / 2 compression, and when playing back it is restored by level expansion.
The dbx achieves a noise reduction effect of more than 30 dB over a wide range from 20 Hz to 20 kHz, and the recording saturation level is + 20 dB, which is more than 10 dB higher than the conventional method.
It uses a simple operation that can be used just by pressing rec for tape recording and play for playback.
Also, the selected position is displayed on the front panel to prevent accidental operation.
You can also play dbx records by washing the dbx disc in the selector.
It also has a bypass position that cancels the dbx circuit with one touch operation.
There are 2 variations, silver and black.
