Extreme voltage shutdown and LED indicator ensure that neither excessive nor insufficient volt-
ages ever reach your valuable equipment.
Premium-quality magnetic circuit breaker with optimized current sensitivity prevent nuisance trip-
ping.
800V peak 250 Amp capable active voltage-switching devices stand up to the toughest power
demands.
Ultra-low contact resistance Super-Spec AC outlets.
Additional AC filtering for Digital outlets.
Description
In these days of overtaxed, commercial AC power facilities, and utilities lowering their standard voltage
levels, the need for stable power has never been greater. A two volt rise or drop in AC voltage can dra-
matically impact power amplifiers and powered sub-woofers, robbing them of their peak power capabil-
ity,. This causes them to overheat, and veer from their optimum performance capabilities. Premium per-
formance requires Stable Regulated AC Power. Furman Sound's new RA-1210 and RA-1220 Stable
Power AC Line Voltage Regulators provide a constant 120VAC while maintaining the ultra-low noise,
cool operating, low-impedance operation that is the hallmark of the Furman Reference Series.

- Page 2 Balanced power. This provides two benefits: Not only does it ensure pure, Stable Power from your home’s AC supply, it also balances it, reducing AC noise dramatically. Additionally, Furman Refer- ence Series products generate virtually no heat, and are more than capable of the full AC current de- mands your system requires for maximum performance.
- Page 3 90-degree angle. All 3-prong AC cords exiting this unit should be dressed away from signal carrying cables as well. If the RA-1210 or RA-1220 is used in tandem with one of Furman’s Symmetrical Power conditioners, the RA should supply the Symmetrical Power Unit. Simply plug the AC input from the Symmetrical Power unit into any of the RA’s analog AC outlets.
- Page 4 Page 4 Surge Protection The RI-1210 and RI-1220 are capable of suppressing virtually any instantaneous voltage surge caused by lightning or commercial power. However, the protection device may be damaged if the over voltage surge or spike is sustained. The same is true if the device is made to absorb a direct lightning hit. The device in conjunction with the magnetic circuit breaker will protect your valued equipment.
- Page 5 Page 5 RA-1210 / RA-1220 SPECIFICATIONS Current Rating: RA-1210 – 10 Amps Continuous at 114 – 126 VAC (9 Amps below regulation threshold of 113VAC) RA-1220 – 20 Amps Continuous at 114 – 126 VAC (19 Amps below regulation threshold of 113VAC) Regulation Range: The RA-1210 and RA-1220 provide AC regulation for a continuous output of 120VAC (+/- 1.5V or less) with an input voltage range of 114VAC to 126VAC.
