The 500 Series, RNC500 Really Nice Compressor from FMR Audio is an APT500-series rack version of the popular Really Nice Compressor. It can be used to provide positive signal control and reduce collateral sonic damage to an audio signal in applications for recording, broadcast TV, post-production, and more.
The RNC500 is built with overcurrent protection and prevents a rare failure from bringing down your whole 500-series rack. There is an early-warning power supply detection circuit that enters bypass and a front panel switch to avoid power-down pops. Other features include a dot, gain-reduction display, sealed, C & K toggle switches, and blue-anodized, machined aluminum knobs. With the 18 gauge, electro-galvanized enclosure, it will keep the electronics safe from harm and protect against EMI interference.
Additionally, the compressor's sound exhibits a sonic neutrality and permits a level-of-control without adding unwanted artifacts. It has a sonic beefiness or a growl that adds a slight, but very compliant, bottom-end to the source material. Overall, the RNC500 is clean, but with a hint of attitude that's under your control.
