Used for about half a year. I am selling it because I am replacing equipment. Operation has been confirmed. Only those who understand that this is a used item, please. Everything in the photos is included. The RNC1773 (Really Nice Compressor) features two different compression modes. One is the normal mode, which has a peak detector and operates as a very standard compressor. The other is the Super Nice mode, which achieves ultra-smooth compression without losing any attack, obtained by layering three compressors. Even renowned professional studios use this small RNC as a secret weapon, demonstrating its true potential. It's an all-around compressor that can be used from tracking to mastering (at an unbelievable price). FMR Audio RNC1773(E) Compressor: Another version of the RNC1773 with special tuning. The op-amps used in the internal analog circuit have been upgraded to high-quality, low-distortion ones. The signal path of the RNC1773 is very simple, consisting only of a VCA IC, op-amps, and passive components such as resistors and capacitors, so the effect is significant. Even comparing the performance of the op-amps alone, the THD+N value is 1/20th of the original! (0.0006% → 0.00003%). Due to its ultimate low distortion, it has high resolution and excellent reproduction of initial reflections and the end of sounds, revealing sounds that can only be heard with this, creating a thrilling sense of realism. 3@3
