Know before you buy
The RM 20 uses a medical-grade toroidal isolation transformer and proprietary NBT filtering to remove electrical noise from your power line. By lowering the noise floor, it allows your equipment to resolve finer details and maintain cleaner, more dynamic musical peaks.
Yes, the unit provides 2,400 VA of power with ultra-low source impedance, which is designed to handle the high current demands of power amplifiers without restricting their dynamic performance. It ensures your gear has access to instantaneous power when the music requires it.
Unlike common surge protectors that use components that degrade or 'sacrifice' themselves over time, the RM 20 uses a series mode design. This provides robust protection against surges without wearing out and without introducing interference into your ground voltage.
Yes, the 10 NEMA 5-20R hospital-grade outlets offer superior contact force and durability. This tighter connection reduces heat buildup and ensures a more reliable, low-resistance power delivery to your components.
The RM 20 weighs 88 lbs, so you should ensure your rack or shelf is rated to handle this weight safely. It is a 3U chassis, so it will occupy three standard rack spaces if you choose the rack-mount faceplate option.
Yes, the RM 20 is designed to attenuate both differential mode (line-to-neutral) and common mode (ground-to-neutral) noise. This comprehensive filtering is essential for eliminating the various types of artifacts that can pollute audio signals.
