FURMAN RI-1220 ISOLATED SYMMETRICAL AC POWER CONDITIONER (20AMPS)
The RI-1210 and RI-1220 Isolated Symmetrical AC Power Conditioners are no-compromise, no-expense-spared designs, with painstaking attention paid to the ultimate sonic and visual impact of every component within them. The Reference Series is the flagship Power Conditioning line of Furman Sound, a more than 25-year-old company that pioneered development of AC power products for the most demanding professional audio and video applications. In the home theater/audiophile domain, the need for clean, low-distortion AC power is nothing new. But the RI-1210 and RI-1220's unrivaled technology and unique implementation are. Many designs in today's market employ simple modified RFI filters; cheap, inadequate AC outlets; high-resistance thermal circuit breakers; and poorly designed ferrite beads. All these components are capable of marginally protecting valuable equipment and reducing some forms of noise. Unfortunately, these can and frequently do add ground noise; distortions such as ringing and phase lags; and raise the AC impedance to an unacceptable level. Others employ more sophisticated means of electronically turning AC power to DC, then synthesizing a clean AC signal from there. This method has its merits for very low current demands. But it can be highly inefficient, contain nonlinear distortions, and at minimum do nothing towards the grave problem of ground noise via digital noise, ground contamination and power supply "backwash" from your AC power source.
Isolated Symmetrical AC Power technology greatly reduces common mode and transverse line noise, typically up to 24 dB per total system. All Symmetrical (balanced) AC receptacles are individually ground fault (GFCI) protected to ensure safe operation.
Includes four sets of isolated, positive contact "Super Spec" AC receptacles with additional filtering for digital components
Handles 20 Amps continuous power (RI-1220) or 10 Amps continuous power (RI-1210)
The toroidal transformer is the finest available, yielding extremely low magnetic field leakage. Additionally, ultra-low-noise DC tolerant technology ensures quiet operation regardless of the load.
A precision, high-inrush magnetic circuit breaker/power switch provides maximum protection, while maintaining the lowest possible contact resistance.
